+# Admin Service Mechanism
+
+Monibuca provides powerful administrative service support for system monitoring, configuration management, plugin management, and other administrative functions. This document details the implementation mechanism and usage of the Admin service.
+
+## Service Architecture
+
+### 1. UI Interface
+
+The Admin service provides a Web management interface by loading the `admin.zip` file. This interface has the following features:
+
+- Unified management interface entry point
+- Access to all server-provided HTTP interfaces
+- Responsive design, supporting various devices
+- Modular function organization
+
+### 2. Configuration Management
+
+Admin service configuration is located in the admin node within global configuration, including:
+
+```yaml
+admin:
+  enableLogin: false    # Whether to enable login mechanism
+  filePath: admin.zip  # Management interface file path
+  homePage: home      # Management interface homepage
+  users:             # User list (effective only when login is enabled)
+    - username: admin   # Username
+      password: admin   # Password
+      role: admin      # Role, options: admin, user
+```
+
+When `enableLogin` is false, all users access as anonymous users.
+When login is enabled and no users exist in the database, the system automatically creates a default admin account (username: admin, password: admin).
+
+### 3. Authentication Mechanism
+
+Admin provides dedicated user login verification interfaces for:
+
+- User identity verification
+- Access token management (JWT)
+- Permission control
+- Session management
+
+### 4. Interface Specifications
+
+All Admin APIs must follow these specifications:
+
+- Response format uniformly includes code, message, and data fields
+- Successful responses use code = 0
+- Error handling uses unified error response format
+- Must perform permission verification
+
+## Function Modules
+
+### 1. System Monitoring
+
+- CPU usage monitoring
+- Memory usage
+- Network bandwidth statistics
+- Disk usage
+- System uptime
+- Online user statistics
+
+### 2. Plugin Management
+
+- Plugin enable/disable
+- Plugin configuration modification
+- Plugin status viewing
+- Plugin version management
+- Plugin dependency checking
+
+### 3. Stream Media Management
+
+- Online stream list viewing
+- Stream status monitoring
+- Stream control (start/stop)
+- Stream information statistics
+- Recording management
+- Transcoding task management
+
+## Security Mechanism
+
+### 1. Authentication Mechanism
+
+- JWT token authentication
+- Session timeout control
+- IP whitelist control
+
+### 2. Permission Control
+
+- Role-Based Access Control (RBAC)
+- Fine-grained permission management
+- Operation audit logging
+- Sensitive operation confirmation
+
+## Best Practices
+
+1. Security
+   - Use HTTPS encryption
+   - Implement strong password policies
+   - Regular key updates
+   - Monitor abnormal access
+
+2. Performance Optimization
+   - Reasonable caching strategy
+   - Paginated query optimization
+   - Asynchronous processing of time-consuming operations
+
+3. Maintainability
+   - Complete operation logs
+   - Clear error messages
+   - Hot configuration updates

+# Monibuca Stream Alias Technical Implementation Documentation
+
+## 1. Feature Overview
+
+Stream Alias is an important feature in Monibuca that allows creating one or more aliases for existing streams, enabling the same stream to be accessed through different paths. This feature is particularly useful in the following scenarios:
+
+- Creating short aliases for streams with long paths
+- Dynamically modifying stream access paths
+- Implementing stream redirection functionality
+
+## 2. Core Data Structures
+
+### 2.1 AliasStream Structure
+
+```go
+type AliasStream struct {
+    *Publisher      // Inherits from Publisher
+    AutoRemove bool // Whether to automatically remove
+    StreamPath string // Original stream path
+    Alias      string // Alias path
+}
+```
+
+### 2.2 StreamAlias Message Structure
+
+```protobuf
+message StreamAlias {
+    string streamPath = 1;  // Original stream path
+    string alias = 2;       // Alias
+    bool autoRemove = 3;    // Whether to automatically remove
+    uint32 status = 4;      // Status
+}
+```
+
+## 3. Core Functionality Implementation
+
+### 3.1 Alias Creation and Modification
+
+When calling the `SetStreamAlias` API to create or modify an alias, the system:
+
+1. Validates and parses the target stream path
+2. Checks if the target stream exists
+3. Handles the following scenarios:
+   - Modifying existing alias: Updates auto-remove flag and stream path
+   - Creating new alias: Initializes new AliasStream structure
+4. Handles subscriber transfer or wakes waiting subscribers
+
+### 3.2 Publisher Startup Alias Handling
+
+When a Publisher starts, the system:
+
+1. Checks for aliases pointing to this Publisher
+2. For each matching alias:
+   - If alias Publisher is empty, sets it to the new Publisher
+   - If alias already has a Publisher, transfers subscribers to the new Publisher
+3. Wakes all subscribers waiting for this stream
+
+### 3.3 Publisher Destruction Alias Handling
+
+Publisher destruction process:
+
+1. Checks if stopped due to being kicked out
+2. Removes Publisher from Streams
+3. Iterates through all aliases, for those pointing to this Publisher:
+   - If auto-remove is set, deletes the alias
+   - Otherwise, retains alias structure
+4. Handles related subscribers
+
+### 3.4 Subscriber Handling Mechanism
+
+When a new subscription request arrives:
+
+1. Checks for matching alias
+2. If alias exists:
+   - If alias Publisher exists: adds subscriber
+   - If Publisher doesn't exist: triggers OnSubscribe event
+3. If no alias exists:
+   - Checks for matching regex alias
+   - Checks if original stream exists
+   - Adds subscriber or joins wait list based on conditions
+
+## 4. API Interfaces
+
+### 4.1 Set Alias
+
+```http
+POST /api/stream/alias
+```
+
+Request body:
+```json
+{
+    "streamPath": "original stream path",
+    "alias": "alias path",
+    "autoRemove": false
+}
+```
+
+### 4.2 Get Alias List
+
+```http
+GET /api/stream/alias
+```
+
+Response body:
+```json
+{
+    "code": 0,
+    "message": "",
+    "data": [
+        {
+            "streamPath": "original stream path",
+            "alias": "alias path",
+            "autoRemove": false,
+            "status": 1
+        }
+    ]
+}
+```
+
+## 5. Status Descriptions
+
+Alias status descriptions:
+- 0: Initial state
+- 1: Alias associated with Publisher
+- 2: Original stream with same name exists
+
+## 6. Best Practices
+
+1. Using Auto-Remove (autoRemove)
+   - Enable auto-remove when temporary stream redirection is needed
+   - This ensures automatic alias cleanup when original stream ends
+
+2. Alias Naming Recommendations
+   - Use short, meaningful aliases
+   - Avoid special characters
+   - Use standardized path format
+
+3. Performance Considerations
+   - Alias mechanism uses efficient memory mapping
+   - Maintains connection state during subscriber transfer
+   - Supports dynamic modification without service restart
+
+## 7. Important Notes
+
+1. Alias Conflict Handling
+   - System handles appropriately when created alias conflicts with existing stream path
+   - Recommended to check for conflicts before creating aliases
+
+2. Subscriber Behavior
+   - Existing subscribers are transferred to new stream when alias is modified
+   - Ensure clients can handle stream redirection
+
+3. Resource Management
+   - Clean up unnecessary aliases promptly
+   - Use auto-remove feature appropriately
+   - Monitor alias status to avoid resource leaks

+# Monibuca Configuration Mechanism
+
+Monibuca employs a flexible configuration system that supports multiple configuration methods. Configuration files use the YAML format and can be initialized either through files or by directly passing configuration objects.
+
+## Configuration Loading Process
+
+1. Configuration initialization occurs during Server startup and can be provided through one of three methods:
+   - YAML configuration file path
+   - Byte array containing YAML configuration content
+   - Raw configuration object (RawConfig)
+
+2. Configuration parsing process:
+   ```go
+   // Supports three configuration input methods
+   case string:  // Configuration file path
+   case []byte:  // YAML configuration content
+   case RawConfig:  // Raw configuration object
+   ```
+
+## Configuration Structure
+
+### Simplified Configuration Syntax
+
+When a configuration item's value is a struct or map type, the system supports a simplified configuration approach: if a simple type value is configured directly, that value will be automatically assigned to the first field of the struct.
+
+For example, given the following struct:
+```go
+type Config struct {
+    Port int
+    Host string
+}
+```
+
+You can use simplified syntax:
+```yaml
+plugin: 1935  # equivalent to plugin: { port: 1935 }
+```
+
+### Configuration Deserialization Mechanism
+
+Each plugin contains a `config.Config` type field for storing and managing configuration information. The configuration loading priority from highest to lowest is:
+
+1. User configuration (via `ParseUserFile`)
+2. Default configuration (via `ParseDefaultYaml`)
+3. Global configuration (via `ParseGlobal`)
+4. Plugin-specific configuration (via `Parse`)
+5. Common configuration (via `Parse`)
+
+Configurations are automatically deserialized into the plugin's public properties. For example:
+
+```go
+type MyPlugin struct {
+    Plugin
+    Port    int    `yaml:"port"`
+    Host    string `yaml:"host"`
+}
+```
+
+Corresponding YAML configuration:
+```yaml
+myplugin:
+    port: 8080
+    host: "localhost"
+```
+
+The configuration will automatically deserialize to the `Port` and `Host` fields. You can query configurations using methods provided by `Config`:
+- `Has(name string)` - Check if a configuration exists
+- `Get(name string)` - Get the value of a configuration
+- `GetMap()` - Get a map of all configurations
+
+Additionally, plugin configurations support saving modifications:
+```go
+func (p *Plugin) SaveConfig() (err error)
+```
+This saves the modified configuration to `{settingDir}/{pluginName}.yaml`.
+
+### Global Configuration
+
+Global configuration is located under the `global` node in the YAML file and includes these main configuration items:
+
+```yaml
+global:
+  settingDir: ".m7s"        # Settings directory
+  fatalDir: "fatal"         # Error log directory
+  pulseInterval: "5s"       # Heartbeat interval
+  disableAll: false         # Whether to disable all plugins
+  streamAlias:              # Stream alias configuration
+    pattern: "target"       # Regex -> target path
+  location:                 # HTTP routing rules
+    pattern: "target"       # Regex -> target address
+  admin:                    # Admin interface configuration
+    enableLogin: false      # Whether to enable login mechanism
+    filePath: "admin.zip"   # Admin interface file path
+    homePage: "home"        # Admin interface homepage
+    users:                  # User list (effective only when login is enabled)
+      - username: "admin"   # Username
+        password: "admin"   # Password
+        role: "admin"       # Role (admin/user)
+```
+
+### Database Configuration
+
+If database connection is configured, the system will automatically:
+
+1. Connect to the database
+2. Auto-migrate data models
+3. Initialize user data (if login is enabled)
+4. Initialize proxy configurations
+
+```yaml
+global:
+  db:
+    dsn: ""                # Database connection string
+    type: ""              # Database type
+```
+
+### Proxy Configuration
+
+The system supports pull and push proxy configurations:
+
+```yaml
+global:
+  pullProxy:              # Pull proxy configuration
+    - id: 1              # Proxy ID
+      name: "proxy1"     # Proxy name
+      url: "rtmp://..."  # Proxy address
+      type: "rtmp"       # Proxy type
+      pullOnStart: true  # Whether to pull on startup
+
+  pushProxy:              # Push proxy configuration
+    - id: 1              # Proxy ID
+      name: "proxy1"     # Proxy name
+      url: "rtmp://..."  # Proxy address
+      type: "rtmp"       # Proxy type
+      pushOnStart: true  # Whether to push on startup
+      audio: true        # Whether to push audio
+```
+
+## Plugin Configuration
+
+Each plugin can have its own configuration node, named as the lowercase version of the plugin name:
+
+```yaml
+rtmp:                    # RTMP plugin configuration
+  port: 1935            # Listen port
+
+rtsp:                   # RTSP plugin configuration
+  port: 554             # Listen port
+```
+
+## Configuration Priority
+
+The configuration system uses a multi-level priority mechanism, from highest to lowest:
+
+1. URL Query Parameter Configuration - Configurations specified via URL query parameters during publishing or subscribing have the highest priority
+   ```
+   Example: rtmp://localhost/live/stream?audio=false
+   ```
+
+2. Plugin-Specific Configuration - Configuration items under the plugin's configuration node
+   ```yaml
+   rtmp:
+     publish:
+       audio: true
+     subscribe:
+       audio: true
+   ```
+
+3. Global Configuration - Configuration items under the global node
+   ```yaml
+   global:
+     publish:
+       audio: true
+     subscribe:
+       audio: true
+   ```
+
+## Common Configuration
+
+There are some common configuration items that can appear in both global and plugin configurations. When plugins use these items, they prioritize values from plugin configuration, falling back to global configuration if not set in plugin configuration.
+
+Main common configurations include:
+
+1. Publish Configuration
+   ```yaml
+   publish:
+     audio: true          # Whether to include audio
+     video: true          # Whether to include video
+     bufferLength: 1000   # Buffer length
+   ```
+
+2. Subscribe Configuration
+   ```yaml
+   subscribe:
+     audio: true          # Whether to subscribe to audio
+     video: true          # Whether to subscribe to video
+     bufferLength: 1000   # Buffer length
+   ```
+
+3. HTTP Configuration
+   ```yaml
+   http:
+     listenAddr: ":8080"  # Listen address
+   ```
+
+4. Other Common Configurations
+   - PublicIP - Public IP
+   - PublicIPv6 - Public IPv6
+   - LogLevel - Log level
+   - EnableAuth - Whether to enable authentication
+
+Usage example:
+
+```yaml
+# Global configuration
+global:
+  publish:
+    audio: true
+    video: true
+  subscribe:
+    audio: true
+    video: true
+
+# Plugin configuration (higher priority than global)
+rtmp:
+  publish:
+    audio: false  # Overrides global configuration
+  subscribe:
+    video: false  # Overrides global configuration
+
+# URL query parameters (highest priority)
+# rtmp://localhost/live/stream?audio=true&video=false
+```
+
+## Hot Configuration Update
+
+Currently, the system supports hot updates for the admin interface file (admin.zip), periodically checking for changes and automatically reloading.
+
+## Configuration Validation
+
+The system performs basic validation of configurations at startup:
+
+1. Checks necessary directory permissions
+2. Validates database connections
+3. Validates user configurations (if login is enabled)

+# Database Mechanism
+
+Monibuca provides database support functionality, allowing database configuration and usage in both global settings and plugins.
+
+## Configuration
+
+### Global Configuration
+
+Database can be configured in global settings using these fields:
+
+```yaml
+global:
+  dsn: "database connection string"
+  dbType: "database type"
+```
+
+### Plugin Configuration
+
+Each plugin can have its own database configuration:
+
+```yaml
+pluginName:
+  dsn: "database connection string"
+  dbType: "database type"
+```
+
+## Database Initialization Process
+
+### Global Database Initialization
+
+1. When the server starts, if `dsn` is configured, it attempts to connect to the database
+2. After successful connection, the following models are automatically migrated:
+   - User table
+   - PullProxy table
+   - PushProxy table
+   - StreamAliasDB table
+
+3. If login is enabled (`Admin.EnableLogin = true`), users are created or updated based on the configuration file
+4. If no users exist in the database, a default admin account is created:
+   - Username: admin
+   - Password: admin
+   - Role: admin
+
+### Plugin Database Initialization
+
+1. During plugin initialization, the plugin's `dsn` configuration is checked
+2. If the plugin's `dsn` matches the global configuration, the global database connection is used
+3. If the plugin configures a different `dsn`, a new database connection is created
+4. If the plugin implements the Recorder interface, the RecordStream table is automatically migrated
+
+## Database Usage
+
+### Global Database Access
+
+The global database can be accessed through the Server instance:
+
+```go
+server.DB
+```
+
+### Plugin Database Access
+
+Plugins can access their database through their instance:
+
+```go
+plugin.DB
+```
+
+## Important Notes
+
+1. Database connection failures will disable related functionality
+2. Plugins using independent databases need to manage their own database connections
+3. Database migration failures will cause plugins to be disabled
+4. It's recommended to reuse the global database connection when possible to avoid creating too many connections
+
+## Built-in Tables
+
+### User Table
+Stores user information, including:
+- Username: User's name
+- Password: User's password
+- Role: User's role (admin/user)
+
+### PullProxy Table
+Stores pull proxy configurations
+
+### PushProxy Table
+Stores push proxy configurations
+
+### StreamAliasDB Table
+Stores stream alias configurations
+
+### RecordStream Table

+# gRPC Service Mechanism
+
+Monibuca provides gRPC service support, allowing plugins to offer services via the gRPC protocol. This document explains the implementation mechanism and usage of gRPC services.
+
+## Service Registration Mechanism
+
+### 1. Service Registration
+
+Plugins need to pass ServiceDesc and Handler when calling `InstallPlugin` to register gRPC services:
+
+```go
+// Example: Registering gRPC service in a plugin
+type MyPlugin struct {
+    pb.UnimplementedApiServer
+    m7s.Plugin
+}
+
+var _ = m7s.InstallPlugin[MyPlugin](
+    m7s.DefaultYaml(`your yaml config here`),
+    &pb.Api_ServiceDesc,           // gRPC service descriptor
+    pb.RegisterApiHandler,         // gRPC gateway handler
+    // ... other parameters
+)
+```
+
+### 2. Proto File Specifications
+
+All gRPC services must follow these Proto file specifications:
+
+- Response structs must include code, message, and data fields
+- Error handling should return errors directly, without manually setting code and message
+- Run `sh scripts/protoc.sh` to generate pb files after modifying global.proto
+- Run `sh scripts/protoc.sh {pluginName}` to generate corresponding pb files after modifying plugin-related proto files
+
+## Service Implementation Mechanism
+
+### 1. Server Configuration
+
+gRPC services use port settings from the global TCP configuration:
+
+```yaml
+global:
+  tcp:
+    listenaddr: :8080     # gRPC service listen address and port
+    listentls: :8443      # gRPC TLS service listen address and port (if enabled)
+```
+
+Configuration items include:
+- Listen address and port settings (specified in global TCP configuration)
+- TLS/SSL certificate configuration (if enabled)
+
+### 2. Error Handling
+
+Error handling follows these principles:
+
+- Return errors directly, no need to manually set code and message
+- The system automatically handles errors and sets response format
+
+## Best Practices
+
+1. Service Definition
+   - Clear service interface design
+   - Appropriate method naming
+   - Complete interface documentation
+
+2. Performance Optimization
+   - Use streaming for large data
+   - Set reasonable timeout values
+
+3. Security Considerations
+   - Enable TLS encryption as needed
+   - Implement necessary access controls

+# HTTP Service Mechanism
+
+Monibuca provides comprehensive HTTP service support, including RESTful API, WebSocket, HTTP-FLV, and other protocols. This document details the implementation mechanism and usage of the HTTP service.
+
+## HTTP Configuration
+
+### 1. Configuration Priority
+
+- Plugin HTTP configuration takes precedence over global HTTP configuration
+- If a plugin doesn't have HTTP configuration, global HTTP configuration is used
+
+### 2. Configuration Items
+
+```yaml
+# Global configuration example
+global:
+  http:
+    listenaddr: :8080  # Listen address and port
+    listentlsaddr: :8081 # TLS listen address and port
+    certfile: ""       # SSL certificate file path
+    keyfile: ""        # SSL key file path
+    cors: true        # Whether to allow CORS
+    username: ""      # Basic auth username
+    password: ""      # Basic auth password
+
+# Plugin configuration example (takes precedence over global config)
+plugin_name:
+  http:
+    listenaddr: :8081
+    cors: false
+    username: "admin"
+    password: "123456"
+```
+
+## Service Processing Flow
+
+### 1. Request Processing Order
+
+When the HTTP server receives a request, it processes it in the following order:
+
+1. First attempts to forward to the corresponding gRPC service
+2. If no corresponding gRPC service is found, looks for plugin-registered HTTP handlers
+3. If nothing is found, returns a 404 error
+
+### 2. Handler Registration Methods
+
+Plugins can register HTTP handlers in two ways:
+
+1. Reflection Registration: The system automatically obtains plugin handling methods through reflection
+   - Method names must start with uppercase to be reflected (Go language rule)
+   - Usually use `API_` as method name prefix (recommended but not mandatory)
+   - Method signature must be `func(w http.ResponseWriter, r *http.Request)`
+   - URL path auto-generation rules:
+     - Underscores `_` in method names are converted to slashes `/`
+     - Example: `API_relay_` method maps to `/API/relay/*` path
+   - If a method name ends with underscore, it indicates a wildcard path that matches any subsequent path
+
+2. Manual Registration: Plugin implements `IRegisterHandler` interface for manual registration
+   - Lowercase methods can't be reflected, must be registered manually
+   - Manual registration can use path parameters (like `:id`)
+   - More flexible routing rule configuration
+
+Example code:
+```go
+// Reflection registration example
+type YourPlugin struct {
+    // ...
+}
+
+// Uppercase start, can be reflected
+// Automatically maps to /API/relay/*
+func (p *YourPlugin) API_relay_(w http.ResponseWriter, r *http.Request) {
+    // Handle wildcard path requests
+}
+
+// Lowercase start, can't be reflected, needs manual registration
+func (p *YourPlugin) handleUserRequest(w http.ResponseWriter, r *http.Request) {
+    // Handle parameterized requests
+}
+
+// Manual registration example
+func (p *YourPlugin) RegisterHandler() {
+    // Can use path parameters
+    engine.GET("/api/user/:id", p.handleUserRequest)
+}
+```
+
+## Middleware Mechanism
+
+### 1. Adding Middleware
+
+Plugins can add global middleware using the `AddMiddleware` method to handle all HTTP requests. Middleware executes in the order it was added.
+
+Example code:
+```go
+func (p *YourPlugin) OnInit() {
+    // Add authentication middleware
+    p.GetCommonConf().AddMiddleware(func(next http.HandlerFunc) http.HandlerFunc {
+        return func(w http.ResponseWriter, r *http.Request) {
+            // Execute before request handling
+            if !authenticate(r) {
+                http.Error(w, "Unauthorized", http.StatusUnauthorized)
+                return
+            }
+            // Call next handler
+            next(w, r)
+            // Execute after request handling
+        }
+    })
+}
+```
+
+### 2. Middleware Use Cases
+
+- Authentication and Authorization
+- Request Logging
+- CORS Handling
+- Request Rate Limiting
+- Response Header Setting
+- Error Handling
+- Performance Monitoring
+
+## Special Protocol Support
+
+### 1. HTTP-FLV
+
+- Supports HTTP-FLV live stream distribution
+- Automatically generates FLV headers
+- Supports GOP caching
+- Supports WebSocket-FLV
+
+### 2. HTTP-MP4
+
+- Supports HTTP-MP4 stream distribution
+- Supports fMP4 file distribution
+
+### 3. HLS
+- Supports HLS protocol
+- Supports MPEG-TS encapsulation
+
+### 4. WebSocket
+
+- Supports custom message protocols
+- Supports ws-flv
+- Supports ws-mp4

+# Logging Mechanism
+
+Monibuca uses Go's standard library `slog` as its logging system, providing structured logging functionality.
+
+## Log Configuration
+
+In the global configuration, you can set the log level through the `LogLevel` field. Supported log levels are:
+
+- trace
+- debug
+- info 
+- warn
+- error
+
+Configuration example:
+
+```yaml
+global:
+  LogLevel: "debug" # Set log level to debug
+```
+
+## Log Format
+
+The default log format includes the following information:
+
+- Timestamp (format: HH:MM:SS.MICROSECONDS)
+- Log level
+- Log message
+- Structured fields
+
+Example output:
+```
+15:04:05.123456 INFO server started
+15:04:05.123456 ERROR failed to connect database dsn="xxx" type="mysql"
+```
+
+## Log Handlers
+
+Monibuca uses `console-slog` as the default log handler, which provides:
+
+1. Color output support
+2. Microsecond-level timestamps
+3. Structured field formatting
+
+### Multiple Handler Support
+
+Monibuca implements a `MultiLogHandler` mechanism, supporting multiple log handlers simultaneously. This provides the following advantages:
+
+1. Can output logs to multiple targets simultaneously (e.g., console, file, log service)
+2. Supports dynamic addition and removal of log handlers
+3. Each handler can have its own log level settings
+4. Supports log grouping and property inheritance
+
+Through the plugin system, various logging methods can be extended, for example:
+
+- LogRotate plugin: Supports log file rotation
+- VMLog plugin: Supports storing logs in VictoriaMetrics time-series database
+
+## Using Logs in Plugins
+
+Each plugin inherits the server's log configuration. Plugins can log using the following methods:
+
+```go
+plugin.Info("message", "key1", value1, "key2", value2)  // Log INFO level
+plugin.Debug("message", "key1", value1)                 // Log DEBUG level
+plugin.Warn("message", "key1", value1)                  // Log WARN level
+plugin.Error("message", "key1", value1)                 // Log ERROR level
+```
+
+## Log Initialization Process
+
+1. Create default console log handler at server startup
+2. Read log level settings from configuration file
+3. Apply log level configuration
+4. Set inherited log configuration for each plugin
+
+## Best Practices
+
+1. Use Log Levels Appropriately
+   - trace: For most detailed tracing information
+   - debug: For debugging information
+   - info: For important information during normal operation
+   - warn: For warning information
+   - error: For error information
+
+2. Use Structured Fields
+   - Avoid concatenating variables in messages
+   - Use key-value pairs to record additional information
+
+3. Error Handling
+   - Include complete error information when logging errors
+   - Add relevant context information
+
+Example:
+```go
+// Recommended
+s.Error("failed to connect database", "error", err, "dsn", dsn)
+
+// Not recommended
+s.Error("failed to connect database: " + err.Error())
+```
+
+## Extending the Logging System
+
+To extend the logging system, you can:
+
+1. Implement custom `slog.Handler` interface
+2. Use `LogHandler.Add()` method to add new handlers
+3. Provide more complex logging functionality through the plugin system
+
+Example of adding a custom log handler:
+
+```go
+type MyLogHandler struct {
+    slog.Handler
+}
+
+// Add handler during plugin initialization
+func (p *MyPlugin) OnInit() error {
+    handler := &MyLogHandler{}
+    p.Server.LogHandler.Add(handler)
+    return nil
+}
+```

+# Plugin System
+
+Monibuca adopts a plugin-based architecture design, extending functionality through its plugin mechanism. The plugin system is one of Monibuca's core features, allowing developers to add new functionality in a modular way without modifying the core code.
+
+## Plugin Lifecycle
+
+The plugin system has complete lifecycle management, including the following phases:
+
+### 1. Registration Phase
+
+Plugins are registered using the `InstallPlugin` generic function, during which:
+
+- Plugin metadata (PluginMeta) is created, including:
+  - Plugin name: automatically extracted from the plugin struct name (removing "Plugin" suffix)
+  - Plugin version: extracted from the caller's file path or package path, defaults to "dev" if not extractable
+  - Plugin type: obtained through reflection of the plugin struct type
+  
+- Optional features are registered:
+  - Exit handler (OnExitHandler)
+  - Default configuration (DefaultYaml)
+  - Puller
+  - Pusher
+  - Recorder
+  - Transformer
+  - Publish authentication (AuthPublisher)
+  - Subscribe authentication (AuthSubscriber)
+  - gRPC service (ServiceDesc)
+  - gRPC gateway handler (RegisterGRPCHandler)
+
+- Plugin metadata is added to the global plugin list
+
+The registration phase is the first stage in a plugin's lifecycle, providing the plugin system with basic information and functional definitions, preparing for subsequent initialization and startup.
+
+### 2. Initialization Phase (Init)
+
+Plugins are initialized through the `Plugin.Init` method, including these steps:
+
+1. Instance Verification
+   - Check if the plugin implements the IPlugin interface
+   - Get plugin instance through reflection
+
+2. Basic Setup
+   - Set plugin metadata and server reference
+   - Configure plugin logger
+   - Set plugin name and version information
+
+3. Environment Check
+   - Check if plugin is disabled by environment variables ({PLUGIN_NAME}_ENABLE=false)
+   - Check global disable status (DisableAll)
+   - Check enable status in user configuration (enable)
+
+4. Configuration Loading
+   - Parse common configuration
+   - Load default YAML configuration
+   - Merge user configuration
+   - Apply final configuration and log
+
+5. Database Initialization (if needed)
+   - Check database connection configuration (DSN)
+   - Establish database connection
+   - Auto-migrate database tables (for recording functionality)
+
+6. Status Recording
+   - Record plugin version
+   - Record user configuration
+   - Set log level
+   - Record initialization status
+
+If errors occur during initialization:
+- Plugin is marked as disabled
+- Disable reason is recorded
+- Plugin is added to the disabled plugins list
+
+The initialization phase prepares necessary environment and resources for plugin operation, crucial for ensuring normal plugin operation.
+
+### 3. Startup Phase (Start)
+
+Plugins start through the `Plugin.Start` method, executing these operations in sequence:
+
+1. gRPC Service Registration (if configured)
+   - Register gRPC service
+   - Register gRPC gateway handler
+   - Handle gRPC-related errors
+
+2. Plugin Management
+   - Add plugin to server's plugin list
+   - Set plugin status to running
+
+3. Network Listener Initialization
+   - Start HTTP/HTTPS services
+   - Start TCP/TLS services (if implementing ITCPPlugin interface)
+   - Start UDP services (if implementing IUDPPlugin interface)
+   - Start QUIC services (if implementing IQUICPlugin interface)
+
+4. Plugin Initialization Callback
+   - Call plugin's OnInit method
+   - Handle initialization errors
+
+5. Timer Task Setup
+   - Configure server keepalive task (if enabled)
+   - Set up other timer tasks
+
+If errors occur during startup:
+- Error reason is recorded
+- Plugin is marked as disabled
+- Subsequent startup steps are stopped
+
+The startup phase is crucial for plugins to begin providing services, with all preparations completed and ready for business logic processing.
+
+### 4. Stop Phase (Stop)
+
+The plugin stop phase is implemented through the `Plugin.OnStop` method and related stop handling logic, including:
+
+1. Service Shutdown
+   - Stop all network services (HTTP/HTTPS/TCP/UDP/QUIC)
+   - Close all network connections
+   - Stop processing new requests
+
+2. Resource Cleanup
+   - Stop all timer tasks
+   - Close database connections (if any)
+   - Clean up temporary files and cache
+
+3. Status Handling
+   - Update plugin status to stopped
+   - Remove from server's active plugin list
+   - Trigger stop event notifications
+
+4. Callback Processing
+   - Call plugin's custom OnStop method
+   - Execute registered stop callback functions
+   - Handle errors during stop process
+
+5. Connection Handling
+   - Wait for current request processing to complete
+   - Gracefully close existing connections
+   - Reject new connection requests
+
+The stop phase aims to ensure plugins can safely and cleanly stop running without affecting other parts of the system.
+
+### 5. Destroy Phase (Destroy)
+
+The plugin destroy phase is implemented through the `Plugin.Dispose` method, the final phase in a plugin's lifecycle, including:
+
+1. Resource Release
+   - Call plugin's OnStop method for stop processing
+   - Remove from server's plugin list
+   - Release all allocated system resources
+
+2. Status Cleanup
+   - Clear all plugin status information
+   - Reset plugin internal variables
+   - Clear plugin configuration information
+
+3. Connection Disconnection
+   - Disconnect all connections with other plugins
+   - Clean up plugin dependencies
+   - Remove event listeners
+
+4. Data Cleanup
+   - Clean up temporary data generated by plugin
+   - Close and clean up database connections
+   - Delete unnecessary files
+
+5. Final Processing
+   - Execute registered destroy callback functions
+   - Log destruction
+   - Ensure all resources are properly released
+
+The destroy phase aims to ensure plugins completely clean up all resources, leaving no residual state, preventing memory and resource leaks.

+# Core Relay Process
+
+## Publisher
+
+A Publisher is an object that writes audio/video data to the RingBuffer on the server. It exposes WriteVideo and WriteAudio methods.
+When writing through WriteVideo and WriteAudio, it creates Tracks, parses data, and generates ICodecCtx. To start publishing, simply call the Plugin's Publish method.
+
+### Accepting Stream Push
+
+Plugins like rtmp, rtsp listen on a port to accept stream pushes.
+
+### Pulling Streams from Remote
+
+- Plugins that implement OnPullProxyAdd method can pull streams from remote sources.
+- Plugins that inherit from HTTPFilePuller can pull streams from http or files.
+
+### Pulling from Local Recording Files
+
+Plugins that inherit from RecordFilePuller can pull streams from local recording files.
+
+## Subscriber
+
+A Subscriber is an object that reads audio/video data from the RingBuffer. Subscribing to a stream involves two steps:
+
+1. Call the Plugin's Subscribe method, passing StreamPath and Subscribe configuration.
+2. Call the PlayBlock method to start reading data, which blocks until the subscription ends.
+
+The reason for splitting into two steps is that the first step might fail (timeout etc.), or might need some interaction work after the first step succeeds.
+The first step will block for some time, waiting for the publisher (if there's no publisher initially) and waiting for the publisher's tracks to be created.
+
+### Accepting Stream Pull
+
+For example, rtmp and rtsp plugins listen on a port to accept playback requests.
+
+### Pushing to Remote
+
+- Plugins that implement OnPushProxyAdd method can push streams to remote destinations.
+
+### Writing to Local Files
+
+Plugins with recording functionality need to subscribe to the stream before writing to local files.
+
+## On-Demand Pull (Publishing)
+
+Triggered by subscribers, when calling plugin's OnSubscribe, it notifies all plugins of a subscription demand, at which point plugins can respond to this demand by publishing a stream. For example, pulling recording streams falls into this category. It's crucial to configure using regular expressions to prevent simultaneous publishing.

+# Task Mechanism
+
+The task mechanism permeates the entire project, defined in the /pkg/task directory. When designing any logic, you must first consider implementing it using the task mechanism, which ensures observability and panic capture, among other benefits.
+
+## Concept Definitions
+
+### Inheritance
+
+In the task mechanism, all tasks are implemented through inheritance.
+While Go doesn't have inheritance, it can be achieved through embedding.
+
+### Macro Task
+
+A macro task, also called a parent task, can contain multiple child tasks and is itself a task.
+
+### Child Task Goroutine
+
+Each macro task starts a goroutine to execute the Start, Run, and Dispose methods of child tasks. Therefore, child tasks sharing the same parent task can avoid concurrent execution issues. This goroutine might not be created immediately, implementing lazy loading.
+
+## Task Definition
+
+Tasks are typically defined by inheriting from `task.Task`, `task.Job`, `task.Work`, `task.ChannelTask`, or `task.TickTask`.
+For example:
+```go
+type MyTask struct {
+    task.Task
+}
+```
+- `task.Task` is the base class for all tasks, defining basic task properties and methods.
+- `task.Job` can contain child tasks and ends when all child tasks complete.
+- `task.Work` similar to Job, but continues executing after child tasks complete.
+- `task.ChannelTask` custom signal task, implemented by overriding the `GetSignal` method.
+- `task.TickTask` timer task, inherits from `task.ChannelTask`, controls timer interval by overriding `GetTickInterval` method.
+
+### Defining Task Start Method
+
+Implement task startup by defining a Start() error method.
+
+The returned error indicates whether the task started successfully. Nil indicates successful startup, otherwise indicates startup failure (special case: returning Complete indicates task completion).
+
+Start typically includes resource creation, such as opening files, establishing network connections, etc.
+
+The Start method is optional; if not defined, startup is considered successful by default.
+
+### Defining Task Execution Process
+
+Implement task execution process by defining a Run() error method.
+
+This method typically executes time-consuming operations and blocks the parent task's child task goroutine.
+
+There's also a non-blocking way to run time-consuming operations by defining a Go() error method.
+
+A nil error return indicates successful execution, otherwise indicates execution failure (special case: returning Complete indicates task completion).
+
+Run and Go are optional; if not defined, the task remains in running state.
+
+### Defining Task Destruction Process
+
+Implement task destruction process by defining a Dispose() method.
+
+This method typically releases resources, such as closing files, network connections, etc.
+
+The Dispose method is optional; if not defined, no action is taken when the task ends.
+
+## Hook Mechanism
+
+Implement hooks through OnStart, OnBeforeDispose, and OnDispose methods.
+
+## Waiting for Task Start and End
+
+Implement waiting for task start and end through WaitStarted() and WaitStopped() methods. This approach blocks the current goroutine.
+
+## Retry Mechanism
+
+Implement retry mechanism by setting Task's RetryCount and RetryInterval. There's a setting method, SetRetry(maxRetry int, retryInterval time.Duration).
+
+### Trigger Conditions
+
+- When Start fails, it retries calling Start until successful.
+- When Run or Go fails, it calls Dispose to release resources before calling Start to begin the retry process.
+
+### Termination Conditions
+
+- Retries stop when the retry count is exhausted.
+- Retries stop when Start, Run, or Go returns ErrStopByUser, ErrExit, or ErrTaskComplete.
+
+## Starting a Task
+
+Start a task by calling the parent task's AddTask method. Don't directly call a task's Start method. Start must be called by the parent task.
+
+## Task Stopping
+
+Implement task stopping through the Stop(err error) method. err cannot be nil. Don't override the Stop method when defining tasks.
+
+## Task Stop Reason
+
+Check task stop reason by calling the StopReason() method.
+
+## Call Method
+
+Calling a Job's Call method creates a temporary task to execute a function in the child task goroutine, typically used to access resources like maps that need protection from concurrent read/write. Since this function runs in the child task goroutine, it cannot call WaitStarted, WaitStopped, or other goroutine-blocking logic, as this would cause deadlock.

+# fMP4 Technology Implementation and Application Based on HLS v7
+
+## Author's Foreword
+
+As developers of the Monibuca streaming server, we have been continuously seeking to provide more efficient and flexible streaming solutions. With the evolution of Web frontend technologies, especially the widespread application of Media Source Extensions (MSE), we gradually recognized that traditional streaming transmission solutions can no longer meet the demands of modern applications. During our exploration and practice, we discovered that fMP4 (fragmented MP4) technology effectively bridges traditional media formats with modern Web technologies, providing users with a smoother video experience.
+
+In the implementation of the MP4 plugin for the Monibuca project, we faced the challenge of efficiently converting recorded MP4 files into a format compatible with MSE playback. Through in-depth research on the HLS v7 protocol and fMP4 container format, we ultimately developed a comprehensive solution supporting real-time conversion from MP4 to fMP4, seamless merging of multiple MP4 segments, and optimizations for frontend MSE playback. This article shares our technical exploration and implementation approach during this process.
+
+## Introduction
+
+As streaming media technology evolves, video distribution methods continue to advance. From traditional complete downloads to progressive downloads, and now to widely used adaptive bitrate streaming technology, each advancement has significantly enhanced the user experience. This article will explore the implementation of fMP4 (fragmented MP4) technology based on HLS v7, and how it integrates with Media Source Extensions (MSE) in modern Web frontends to create efficient and smooth video playback experiences.
+
+## Evolution of HLS Protocol and Introduction of fMP4
+
+### Traditional HLS and Its Limitations
+
+HTTP Live Streaming (HLS) is an HTTP adaptive bitrate streaming protocol developed by Apple. In earlier versions, HLS primarily used TS (Transport Stream) segments as the media container format. Although the TS format has good error resilience and streaming characteristics, it also has several limitations:
+
+1. Larger file size compared to container formats like MP4
+2. Each TS segment needs to contain complete initialization information, causing redundancy
+3. Lower integration with other parts of the Web technology stack
+
+### HLS v7 and fMP4
+
+HLS v7 introduced support for fMP4 (fragmented MP4) segments, marking a significant advancement in the HLS protocol. As a media container format, fMP4 offers the following advantages over TS:
+
+1. Smaller file size, higher transmission efficiency
+2. Shares the same underlying container format with other streaming protocols like DASH, facilitating a unified technology stack
+3. Better support for modern codecs
+4. Better compatibility with MSE (Media Source Extensions)
+
+In HLS v7, seamless playback of fMP4 segments is achieved by specifying initialization segments using the `#EXT-X-MAP` tag in the playlist.
+
+## MP4 File Structure and fMP4 Basic Principles
+
+### Traditional MP4 Structure
+
+Traditional MP4 files follow the ISO Base Media File Format (ISO BMFF) specification and mainly consist of the following parts:
+
+1. **ftyp** (File Type Box): Indicates the format and compatibility information of the file
+2. **moov** (Movie Box): Contains metadata about the media, such as track information, codec parameters, etc.
+3. **mdat** (Media Data Box): Contains the actual media data
+
+In traditional MP4, the `moov` is usually located at the beginning or end of the file and contains all the metadata and index data for the entire video. This structure is not friendly for streaming transmission because the player needs to acquire the complete `moov` before playback can begin.
+
+Below is a diagram of the MP4 file box structure:
+
+```mermaid

+### fMP4 Structural Characteristics
+
+fMP4 (fragmented MP4) restructures the traditional MP4 format with the following key features:
+
+1. Divides media data into multiple fragments
+2. Each fragment contains its own metadata and media data
+3. The file structure is more suitable for streaming transmission
+
+The main components of fMP4:
+
+1. **ftyp**: Same as traditional MP4, located at the beginning of the file
+2. **moov**: Contains overall track information, but not specific sample information
+3. **moof** (Movie Fragment Box): Contains metadata for specific fragments
+4. **mdat**: Contains media data associated with the preceding moof
+
+Below is a diagram of the fMP4 file box structure:
+
+```mermaid
+graph TD
+    FMP4[fMP4 File] --> FTYP[ftyp box]
+    FMP4 --> MOOV[moov box]

+    FMP4 --> MDAT1[mdat 1: Fragment 1 media data]

+    MOOF1 --> TRAF1[traf: Track fragment]
+    
+    TRAF1 --> TFHD1[tfhd: Track fragment header]
+    TRAF1 --> TFDT1[tfdt: Track fragment decode time]
+    TRAF1 --> TRUN1[trun: Track run]
+```
+
+This structure allows the player to immediately begin processing subsequent `moof`+`mdat` fragments after receiving the initial `ftyp` and `moov`, making it highly suitable for streaming transmission and real-time playback.
+
+## Conversion Principles from MP4 to fMP4
+
+The MP4 to fMP4 conversion process can be illustrated by the following sequence diagram:
+
+```mermaid
+sequenceDiagram
+    participant MP4 as Source MP4 File
+    participant Demuxer as MP4 Parser
+    participant Muxer as fMP4 Muxer
+    participant fMP4 as Target fMP4 File
+    
+    MP4->>Demuxer: Read MP4 file
+    Note over Demuxer: Parse file structure
+    Demuxer->>Demuxer: Extract ftyp info
+    Demuxer->>Demuxer: Parse moov box
+    Demuxer->>Demuxer: Extract tracks info<br>(video, audio tracks)
+    Demuxer->>Muxer: Pass track metadata
+    
+    Muxer->>fMP4: Write ftyp box
+    Muxer->>Muxer: Create streaming-friendly moov
+    Muxer->>Muxer: Add mvex extension
+    Muxer->>fMP4: Write moov box
+    
+    loop For each media sample
+        Demuxer->>MP4: Read sample data
+        Demuxer->>Muxer: Pass sample
+        Muxer->>Muxer: Create moof box<br>(time and position info)
+        Muxer->>Muxer: Create mdat box<br>(actual media data)
+        Muxer->>fMP4: Write moof+mdat pair
+    end
+    
+    Note over fMP4: Conversion complete
+```
+
+As shown in the diagram, the conversion process consists of three key steps:
+
+1. **Parse the source MP4 file**: Read and parse the structure of the original MP4 file, extract information about video and audio tracks, including codec type, frame rate, resolution, and other metadata.
+
+2. **Create the initialization part of fMP4**: Build the file header and initialization section, including the ftyp and moov boxes. These serve as the initialization segment, containing all the information needed by the decoder, but without actual media sample data.
+
+3. **Create fragments for each sample**: Read the sample data from the original MP4 one by one, then create corresponding moof and mdat box pairs for each sample (or group of samples).
+
+This conversion method transforms MP4 files that were only suitable for download-and-play into fMP4 format suitable for streaming transmission.
+
+## Multiple MP4 Segment Merging Technology
+
+### User Requirement: Time-Range Recording Downloads
+
+In scenarios such as video surveillance, course playback, and live broadcast recording, users often need to download recorded content within a specific time range. For example, a security system operator might only need to export video segments containing specific events, or a student on an educational platform might only want to download key parts of a course. However, since systems typically divide recorded files by fixed durations (e.g., 30 minutes or 1 hour) or specific events (such as the start/end of a live broadcast), the time range needed by users often spans multiple independent MP4 files.
+
+In the Monibuca project, we developed a solution based on time range queries and multi-file merging to address this need. Users only need to specify the start and end times of the content they require, and the system will:
+
+1. Query the database to find all recording files that overlap with the specified time range
+2. Extract relevant time segments from each file
+3. Seamlessly merge these segments into a single downloadable file
+
+This approach greatly enhances the user experience, allowing them to precisely obtain the content they need without having to download and browse through large amounts of irrelevant video content.
+
+### Database Design and Time Range Queries
+
+To support time range queries, our recording file metadata in the database includes the following key fields:
+
+- Stream Path: Identifies the video source
+- Start Time: The start time of the recording segment
+- End Time: The end time of the recording segment
+- File Path: The storage location of the actual recording file
+- Type: The file format, such as "mp4"
+
+When a user requests recordings within a specific time range, the system executes a query similar to the following:
+
+```sql
+SELECT * FROM record_streams 
+WHERE stream_path = ? AND type = 'mp4' 
+AND start_time <= ? AND end_time >= ?
+```
+
+This returns all recording segments that intersect with the requested time range, after which the system needs to extract the relevant parts and merge them.
+
+### Technical Challenges of Multiple MP4 Merging
+
+Merging multiple MP4 files is not a simple file concatenation but requires addressing the following technical challenges:
+
+1. **Timestamp Continuity**: Ensuring that the timestamps in the merged video are continuous, without jumps or overlaps
+2. **Codec Consistency**: Handling cases where different MP4 files may use different encoding parameters
+3. **Metadata Merging**: Correctly merging the moov box information from various files
+4. **Precise Cutting**: Precisely extracting content within the user-specified time range from each file
+
+In practical applications, we implemented two merging strategies: regular MP4 merging and fMP4 merging. These strategies each have their advantages and are suitable for different application scenarios.
+
+### Regular MP4 Merging Process
+
+```mermaid
+sequenceDiagram
+    participant User as User
+    participant API as API Service
+    participant DB as Database
+    participant MP4s as Multiple MP4 Files
+    participant Muxer as MP4 Muxer
+    participant Output as Output MP4 File
+    
+    User->>API: Request time-range recording<br>(stream, startTime, endTime)
+    API->>DB: Query records within specified range
+    DB-->>API: Return matching recording list
+    
+    loop For each MP4 file
+        API->>MP4s: Read file
+        MP4s->>Muxer: Parse file structure
+        Muxer->>Muxer: Parse track info
+        Muxer->>Muxer: Extract media samples
+        Muxer->>Muxer: Adjust timestamps for continuity
+        Muxer->>Muxer: Record sample info and offsets
+        Note over Muxer: Skip samples outside time range
+    end
+    
+    Muxer->>Output: Write ftyp box
+    Muxer->>Output: Write adjusted sample data
+    Muxer->>Muxer: Create moov containing all sample info
+    Muxer->>Output: Write merged moov box
+    Output-->>User: Provide merged file to user
+```
+
+In this approach, the merging process primarily involves arranging media samples from different MP4 files in sequence and adjusting timestamps to ensure continuity. Finally, a new `moov` box containing all sample information is generated. The advantage of this method is its good compatibility, as almost all players can play the merged file normally, making it suitable for download and offline playback scenarios.
+
+It's particularly worth noting that in the code implementation, we handle the overlap relationship between the time range in the parameters and the actual recording time, extracting only the content that users truly need:
+
+```go
+if i == 0 {
+    startTimestamp := startTime.Sub(stream.StartTime).Milliseconds()
+    var startSample *box.Sample
+    if startSample, err = demuxer.SeekTime(uint64(startTimestamp)); err != nil {
+        tsOffset = 0
+        continue
+    }
+    tsOffset = -int64(startSample.Timestamp)
+}
+
+// In the last file, frames beyond the end time are skipped
+if i == streamCount-1 && int64(sample.Timestamp) > endTime.Sub(stream.StartTime).Milliseconds() {
+    break
+}
+```
+
+### fMP4 Merging Process
+
+```mermaid
+sequenceDiagram
+    participant User as User
+    participant API as API Service
+    participant DB as Database
+    participant MP4s as Multiple MP4 Files
+    participant Muxer as fMP4 Muxer
+    participant Output as Output fMP4 File
+    
+    User->>API: Request time-range recording<br>(stream, startTime, endTime)
+    API->>DB: Query records within specified range
+    DB-->>API: Return matching recording list
+    
+    Muxer->>Output: Write ftyp box
+    Muxer->>Output: Write initial moov box<br>(including mvex)
+    
+    loop For each MP4 file
+        API->>MP4s: Read file
+        MP4s->>Muxer: Parse file structure
+        Muxer->>Muxer: Parse track info
+        Muxer->>Muxer: Extract media samples
+        
+        loop For each sample
+            Note over Muxer: Check if sample is within target time range
+            Muxer->>Muxer: Adjust timestamp
+            Muxer->>Muxer: Create moof+mdat pair
+            Muxer->>Output: Write moof+mdat pair
+        end
+    end
+    
+    Output-->>User: Provide merged file to user
+```
+
+The fMP4 merging is more flexible, with each sample packed into an independent `moof`+`mdat` fragment, maintaining independently decodable characteristics, which is more conducive to streaming transmission and random access. This approach is particularly suitable for integration with MSE and HLS, providing support for real-time streaming playback, allowing users to efficiently play merged content directly in the browser without waiting for the entire file to download.
+
+### Handling Codec Compatibility in Merging
+
+In the process of merging multiple recordings, a key challenge we face is handling potential codec parameter differences between files. For example, during long-term recording, a camera might adjust video resolution due to environmental changes, or an encoder might reinitialize, causing changes in encoding parameters.
+
+To solve this problem, Monibuca implements a smart track version management system that identifies changes by comparing encoder-specific data (ExtraData):
+
+```mermaid
+sequenceDiagram
+    participant Muxer as Merger
+    participant Track as Track Manager
+    participant History as Track Version History
+
+    loop For each new track
+        Muxer->>Track: Check track encoding parameters
+        Track->>History: Compare with existing track versions
+        alt Found matching track version
+            History-->>Track: Return existing track
+            Track-->>Muxer: Use existing track
+        else No matching version
+            Track->>Track: Create new track version
+            Track->>History: Add to version history
+            Track-->>Muxer: Use new track
+        end
+    end
+```
+
+This design ensures that even if there are encoding parameter changes in the original recordings, the merged file can maintain correct decoding parameters, providing users with a smooth playback experience.
+
+### Performance Optimization
+
+When processing large video files or a large number of concurrent requests, the performance of the merging process is an important consideration. We have adopted the following optimization measures:
+
+1. **Streaming Processing**: Process samples frame by frame to avoid loading entire files into memory
+2. **Parallel Processing**: Use parallel processing for multiple independent tasks (such as file parsing)
+3. **Smart Caching**: Cache commonly used encoding parameters and file metadata
+4. **On-demand Reading**: Only read and process samples within the target time range
+
+These optimizations enable the system to efficiently process large-scale recording merging requests, completing processing within a reasonable time even for long-term recordings spanning hours or days.
+
+The multiple MP4 merging functionality greatly enhances the flexibility and user experience of Monibuca as a streaming server, allowing users to precisely obtain the recorded content they need, regardless of how the original recordings are segmented and stored.
+
+## Media Source Extensions (MSE) and fMP4 Compatibility Implementation
+
+### MSE Technology Overview
+
+Media Source Extensions (MSE) is a JavaScript API that allows web developers to directly manipulate media stream data. It enables custom adaptive bitrate streaming players to be implemented entirely in the browser without relying on external plugins.
+
+The core working principle of MSE is:
+1. Create a MediaSource object
+2. Create one or more SourceBuffer objects
+3. Append media fragments to the SourceBuffer
+4. The browser is responsible for decoding and playing these fragments
+
+### Perfect Integration of fMP4 with MSE
+
+The fMP4 format has natural compatibility with MSE, mainly reflected in:
+
+1. Each fragment of fMP4 can be independently decoded
+2. The clear separation of initialization segments and media segments conforms to MSE's buffer management model
+3. Precise timestamp control enables seamless splicing
+
+The following sequence diagram shows how fMP4 works with MSE:
+
+```mermaid
+sequenceDiagram
+    participant Client as Browser Client
+    participant Server as Server
+    participant MSE as MediaSource API
+    participant Video as HTML5 Video Element
+    
+    Client->>Video: Create video element
+    Client->>MSE: Create MediaSource object
+    Client->>Video: Set video.src = URL.createObjectURL(mediaSource)
+    MSE-->>Client: sourceopen event
+    
+    Client->>MSE: Create SourceBuffer
+    Client->>Server: Request initialization segment (ftyp+moov)
+    Server-->>Client: Return initialization segment
+    Client->>MSE: appendBuffer(initialization segment)
+    
+    loop During playback
+        Client->>Server: Request media segment (moof+mdat)
+        Server-->>Client: Return media segment
+        Client->>MSE: appendBuffer(media segment)
+        MSE-->>Video: Decode and render frames
+    end
+```
+
+In Monibuca's implementation, we've made special optimizations for MSE: creating independent moof and mdat for each frame. Although this approach adds some overhead, it provides high flexibility, particularly suitable for low-latency real-time streaming scenarios and precise frame-level operations.
+
+## Integration of HLS and fMP4 in Practical Applications
+
+In practical applications, we combine fMP4 technology with the HLS v7 protocol to implement time-range-based on-demand playback. The system can find the corresponding MP4 records from the database based on the time range specified by the user, and then generate an fMP4 format HLS playlist:
+
+```mermaid
+sequenceDiagram
+    participant Client as Client
+    participant Server as HLS Server
+    participant DB as Database
+    participant MP4Plugin as MP4 Plugin
+    
+    Client->>Server: Request fMP4.m3u8<br>with time range parameters
+    Server->>DB: Query MP4 records within specified range
+    DB-->>Server: Return record list
+    
+    Server->>Server: Create HLS v7 playlist<br>Version: 7
+    loop For each record
+        Server->>Server: Calculate duration
+        Server->>Server: Add media segment URL<br>/mp4/download/{stream}.fmp4?id={id}
+    end
+    
+    Server->>Server: Add #EXT-X-ENDLIST marker
+    Server-->>Client: Return HLS playlist
+    
+    loop For each segment
+        Client->>MP4Plugin: Request fMP4 segment
+        MP4Plugin->>MP4Plugin: Convert to fMP4 format
+        MP4Plugin-->>Client: Return fMP4 segment
+    end
+```
+
+Through this approach, we maintain compatibility with existing HLS clients while leveraging the advantages of the fMP4 format to provide more efficient streaming services.
+
+## Conclusion
+
+As a modern media container format, fMP4 combines the efficient compression of MP4 with the flexibility of streaming transmission, making it highly suitable for video distribution needs in modern web applications. Through integration with HLS v7 and MSE technologies, more efficient and flexible streaming services can be achieved.
+
+In the practice of the Monibuca project, we have successfully built a complete streaming solution by implementing MP4 to fMP4 conversion, merging multiple MP4 files, and optimizing fMP4 fragment generation for MSE. The application of these technologies enables our system to provide a better user experience, including faster startup times, smoother quality transitions, and lower bandwidth consumption.
+
+As video technology continues to evolve, fMP4, as a bridge connecting traditional media formats with modern Web technologies, will continue to play an important role in the streaming media field. The Monibuca project will also continue to explore and optimize this technology to provide users with higher quality streaming services.

+# Monibuca 配置机制
+
+Monibuca 采用灵活的配置机制，支持多种配置方式。配置文件采用 YAML 格式，可以通过文件或者直接传入配置对象的方式进行初始化。
+
+## 配置加载流程
+
+1. 配置初始化发生在 Server 启动阶段，通过以下三种方式之一提供配置：
+   - YAML 配置文件路径
+   - YAML 配置内容的字节数组
+   - 原始配置对象 (RawConfig)
+
+2. 配置解析过程：
+   ```go
+   // 支持三种配置输入方式
+   case string:  // 配置文件路径
+   case []byte:  // YAML 配置内容
+   case RawConfig:  // 原始配置对象
+   ```
+
+## 配置结构
+
+### 配置简化语法
+
+当配置项的值是一个结构体或 map 类型时，系统支持一种简化的配置方式：如果直接配置一个简单类型的值，该值会被自动赋给结构体的第一个字段。
+
+例如，对于以下结构体：
+```go
+type Config struct {
+    Port int
+    Host string
+}
+```
+
+可以使用简化语法：
+```yaml
+plugin: 1935  # 等同于 plugin: { port: 1935 }
+```
+
+### 配置反序列化机制
+
+每个插件都包含一个 `config.Config` 类型的字段，用于存储和管理配置信息。配置加载的优先级从高到低是：
+
+1. 用户配置 (通过 `ParseUserFile`)
+2. 默认配置 (通过 `ParseDefaultYaml`)
+3. 全局配置 (通过 `ParseGlobal`)
+4. 插件特定配置 (通过 `Parse`)
+5. 通用配置 (通过 `Parse`)
+
+配置会被自动反序列化到插件的公开属性中。例如：
+
+```go
+type MyPlugin struct {
+    Plugin
+    Port    int    `yaml:"port"`
+    Host    string `yaml:"host"`
+}
+```
+
+对应的 YAML 配置：
+```yaml
+myplugin:
+    port: 8080
+    host: "localhost"
+```
+
+配置会自动反序列化到 `Port` 和 `Host` 字段中。你可以通过 `Config` 提供的方法来查询配置：
+- `Has(name string)` - 检查是否存在某个配置
+- `Get(name string)` - 获取某个配置的值
+- `GetMap()` - 获取所有配置的 map
+
+此外，插件的配置支持保存修改：
+```go
+func (p *Plugin) SaveConfig() (err error)
+```
+这会将修改后的配置保存到 `{settingDir}/{pluginName}.yaml` 文件中。
+
+### 全局配置
+
+全局配置位于 YAML 文件的 `global` 节点下，包含以下主要配置项：
+
+```yaml
+global:
+  settingDir: ".m7s"        # 设置文件目录
+  fatalDir: "fatal"         # 错误日志目录
+  pulseInterval: "5s"       # 心跳间隔
+  disableAll: false         # 是否禁用所有插件
+  streamAlias:              # 流别名配置
+    pattern: "target"       # 正则表达式 -> 目标路径
+  location:                 # HTTP 路由转发规则
+    pattern: "target"       # 正则表达式 -> 目标地址
+  admin:                    # 管理界面配置
+    enableLogin: false      # 是否启用登录机制
+    filePath: "admin.zip"   # 管理界面文件路径
+    homePage: "home"        # 管理界面首页
+    users:                  # 用户列表(仅在启用登录时生效)
+      - username: "admin"   # 用户名
+        password: "admin"   # 密码
+        role: "admin"       # 角色(admin/user)
+```
+
+### 数据库配置
+
+如果配置了数据库连接，系统会自动进行以下操作：
+
+1. 连接数据库
+2. 自动迁移数据模型
+3. 初始化用户数据（如果启用了登录机制）
+4. 初始化代理配置
+
+```yaml
+global:
+  db:
+    dsn: ""                # 数据库连接字符串
+    type: ""              # 数据库类型
+```
+
+### 代理配置
+
+系统支持拉流代理和推流代理配置：
+
+```yaml
+global:
+  pullProxy:              # 拉流代理配置
+    - id: 1              # 代理ID
+      name: "proxy1"     # 代理名称
+      url: "rtmp://..."  # 代理地址
+      type: "rtmp"       # 代理类型
+      pullOnStart: true  # 是否启动时拉流
+
+  pushProxy:              # 推流代理配置
+    - id: 1              # 代理ID
+      name: "proxy1"     # 代理名称
+      url: "rtmp://..."  # 代理地址
+      type: "rtmp"       # 代理类型
+      pushOnStart: true  # 是否启动时推流
+      audio: true        # 是否推送音频
+```
+
+## 插件配置
+
+每个插件可以有自己的配置节点，节点名为插件名称的小写形式：
+
+```yaml
+rtmp:                    # RTMP插件配置
+  port: 1935            # 监听端口
+
+rtsp:                   # RTSP插件配置
+  port: 554             # 监听端口
+```
+
+## 配置优先级
+
+配置系统采用多级优先级机制，从高到低依次为：
+
+1. URL 查询参数配置 - 发布或订阅时通过 URL 查询参数指定的配置具有最高优先级
+   ```
+   例如：rtmp://localhost/live/stream?audio=false
+   ```
+
+2. 插件特定配置 - 在插件配置节点下的配置项
+   ```yaml
+   rtmp:
+     publish:
+       audio: true
+     subscribe:
+       audio: true
+   ```
+
+3. 全局配置 - 在 global 节点下的配置项
+   ```yaml
+   global:
+     publish:
+       audio: true
+     subscribe:
+       audio: true
+   ```
+
+## 通用配置
+
+系统中存在一些通用配置项，这些配置项可以同时出现在全局配置和插件配置中。当插件使用这些配置项时，会优先使用插件配置中的值，如果插件配置中没有设置，则使用全局配置中的值。
+
+主要的通用配置包括：
+
+1. 发布配置（Publish）
+   ```yaml
+   publish:
+     audio: true          # 是否包含音频
+     video: true          # 是否包含视频
+     bufferLength: 1000   # 缓冲长度
+   ```
+
+2. 订阅配置（Subscribe）
+   ```yaml
+   subscribe:
+     audio: true          # 是否订阅音频
+     video: true          # 是否订阅视频
+     bufferLength: 1000   # 缓冲长度
+   ```
+
+3. HTTP 配置
+   ```yaml
+   http:
+     listenAddr: ":8080"  # 监听地址
+   ```
+
+4. 其他通用配置
+   - PublicIP - 公网 IP
+   - PublicIPv6 - 公网 IPv6
+   - LogLevel - 日志级别
+   - EnableAuth - 是否启用认证
+
+使用示例：
+
+```yaml
+# 全局配置
+global:
+  publish:
+    audio: true
+    video: true
+  subscribe:
+    audio: true
+    video: true
+
+# 插件配置（优先级高于全局配置）
+rtmp:
+  publish:
+    audio: false  # 覆盖全局配置
+  subscribe:
+    video: false  # 覆盖全局配置
+
+# URL 查询参数（最高优先级）
+# rtmp://localhost/live/stream?audio=true&video=false
+```
+
+## 配置热更新
+
+目前系统支持管理界面文件（admin.zip）的热更新，会定期检查文件变化并自动重新加载。
+
+## 配置验证
+
+系统在启动时会对配置进行基本验证：
+
+1. 检查必要的目录权限
+2. 验证数据库连接
+3. 验证用户配置（如果启用登录机制）
+
+## 配置示例
+
+完整的配置文件示例：
+
+```yaml
+global:
+  settingDir: ".m7s"
+  fatalDir: "fatal"
+  pulseInterval: "5s"
+  disableAll: false
+  streamAlias:
+    "live/(.*)": "record/$1"
+  location:
+    "^/live/(.*)": "/hls/$1"
+  admin:
+    enableLogin: true
+    filePath: "admin.zip"
+    homePage: "home"
+    users:
+      - username: "admin"
+        password: "admin"
+        role: "admin"
+  db:
+    dsn: "host=localhost user=postgres password=postgres dbname=monibuca port=5432 sslmode=disable TimeZone=Asia/Shanghai"
+    type: "postgres"
+  pullProxy:
+    - id: 1
+      name: "proxy1"
+      url: "rtmp://example.com/live/stream"
+      type: "rtmp"
+      pullOnStart: true

+      audio: true
+
+rtmp:
+  port: 1935
+
+rtsp:
+  port: 554

+# 数据库机制
+
+Monibuca 提供了数据库支持功能，可以在全局配置和插件中分别配置和使用数据库。
+
+## 配置说明
+
+### 全局配置
+
+在全局配置中可以通过以下字段配置数据库：
+
+```yaml
+global:
+  dsn: "数据库连接字符串"
+  dbType: "数据库类型"
+```
+
+### 插件配置
+
+每个插件也可以单独配置数据库：
+
+```yaml
+pluginName:
+  dsn: "数据库连接字符串"
+  dbType: "数据库类型"
+```
+
+## 数据库初始化流程
+
+### 全局数据库初始化
+
+1. 服务器启动时，如果配置了 `dsn`，会尝试连接数据库
+2. 连接成功后会自动迁移以下模型:
+   - User 用户表
+   - PullProxy 拉流代理表
+   - PushProxy 推流代理表
+   - StreamAliasDB 流别名表
+
+3. 如果开启了登录功能(`Admin.EnableLogin = true`)，会根据配置文件创建或更新用户
+4. 如果数据库中没有任何用户，会创建一个默认的管理员账户:
+   - 用户名: admin
+   - 密码: admin
+   - 角色: admin
+
+### 插件数据库初始化
+
+1. 插件初始化时会检查插件配置中的 `dsn`
+2. 如果插件配置的 `dsn` 与全局配置相同，则直接使用全局数据库连接
+3. 如果插件配置了不同的 `dsn`，则会创建新的数据库连接
+4. 如果插件实现了 Recorder 接口，会自动迁移 RecordStream 表
+
+## 数据库使用
+
+### 全局数据库访问
+
+可以通过 Server 实例访问全局数据库:
+
+```go
+server.DB
+```
+
+### 插件数据库访问
+
+插件可以通过自身实例访问数据库:
+
+```go
+plugin.DB
+```
+
+## 注意事项
+
+1. 数据库连接失败会导致相应的功能被禁用
+2. 插件使用独立数据库时需要自行管理数据库连接
+3. 数据库迁移失败会导致插件被禁用
+4. 建议在可能的情况下复用全局数据库连接，避免创建过多连接
+
+## 内置数据表
+
+### User 表
+用于存储用户信息，包含以下字段:
+- Username: 用户名
+- Password: 密码
+- Role: 角色(admin/user)
+
+### PullProxy 表
+用于存储拉流代理配置
+
+### PushProxy 表
+用于存储推流代理配置
+
+### StreamAliasDB 表
+用于存储流别名配置
+
+### RecordStream 表
+用于存储录制相关信息(仅在插件实现 Recorder 接口时创建)

+# GRPC 服务机制
+
+Monibuca 提供了 gRPC 服务支持，允许插件通过 gRPC 协议提供服务。本文档说明了 gRPC 服务的实现机制和使用方法。
+
+## 服务注册机制
+
+### 1. 服务注册
+
+插件注册 gRPC 服务需要在 `InstallPlugin` 时传入 ServiceDesc 和 Handler：
+
+```go
+// 示例：在插件中注册 gRPC 服务
+type MyPlugin struct {
+    pb.UnimplementedApiServer
+    m7s.Plugin
+}
+
+var _ = m7s.InstallPlugin[MyPlugin](
+    m7s.DefaultYaml(`your yaml config here`),
+    &pb.Api_ServiceDesc,           // gRPC service descriptor
+    pb.RegisterApiHandler,         // gRPC gateway handler
+    // ... 其他参数
+)
+```
+
+### 2. Proto 文件规范
+
+所有的 gRPC 服务都需要遵循以下 Proto 文件规范：
+
+- 响应结构体必须包含 code、message、data 字段
+- 错误处理采用直接返回 error 的方式，无需手动设置 code 和 message
+- 修改 global.proto 后需要运行 `sh scripts/protoc.sh` 生成 pb 文件
+- 修改插件相关的 proto 文件后需要运行 `sh scripts/protoc.sh {pluginName}` 生成对应的 pb 文件
+
+## 服务实现机制
+
+### 1. 服务器配置
+
+gRPC 服务使用全局 TCP 配置中的端口设置：
+
+```yaml
+global:
+  tcp:
+    listenaddr: :8080     # gRPC 服务监听地址和端口
+    listentls: :8443      # gRPC TLS 服务监听地址和端口（如果启用）
+```
+
+配置项包括：
+- 监听地址和端口设置（在全局 TCP 配置中指定）
+- TLS/SSL 证书配置（如果启用）
+
+### 2. 错误处理
+
+错误处理遵循以下原则：
+
+- 直接返回 error，无需手动设置 code 和 message
+- 系统会自动处理错误并设置响应格式
+
+## 最佳实践
+
+1. 服务定义
+   - 清晰的服务接口设计
+   - 合理的方法命名
+   - 完整的接口文档
+
+2. 性能优化
+   - 使用流式处理大数据
+   - 合理设置超时时间
+
+3. 安全考虑
+   - 根据需要启用 TLS 加密
+   - 实现必要的访问控制

+# HTTP 服务机制
+
+Monibuca 提供了完整的 HTTP 服务支持，包括 RESTful API、WebSocket、HTTP-FLV 等多种协议支持。本文档详细说明了 HTTP 服务的实现机制和使用方法。
+
+## HTTP 配置
+
+### 1. 配置优先级
+
+- 插件的 HTTP 配置优先于全局 HTTP 配置
+- 如果插件没有配置 HTTP，则使用全局 HTTP 配置
+
+### 2. 配置项说明
+
+```yaml
+# 全局配置示例
+global:
+  http:
+    listenaddr: :8080  # 监听地址和端口
+    listentlsaddr: :8081 # 监听tls地址和端口
+    certfile: ""       # SSL证书文件路径
+    keyfile: ""        # SSL密钥文件路径
+    cors: true        # 是否允许跨域
+    username: ""      # Basic认证用户名
+    password: ""      # Basic认证密码
+
+# 插件配置示例（优先于全局配置）
+plugin_name:
+  http:
+    listenaddr: :8081
+    cors: false
+    username: "admin"
+    password: "123456"
+```
+
+## 服务处理流程
+
+### 1. 请求处理顺序
+
+HTTP 服务器接收到请求后，按以下顺序处理：
+
+1. 首先尝试转发到对应的 gRPC 服务
+2. 如果没有找到对应的 gRPC 服务，则查找插件注册的 HTTP handler
+3. 如果都没有找到，返回 404 错误
+
+### 2. Handler 注册方式
+
+插件可以通过以下两种方式注册 HTTP handler：
+
+1. 反射注册：系统自动通过反射获取插件的处理方法
+   - 方法名必须大写开头才能被反射获取（Go 语言规则）
+   - 通常使用 `API_` 作为方法名前缀（推荐但不强制）
+   - 方法签名必须为 `func(w http.ResponseWriter, r *http.Request)`
+   - URL 路径自动生成规则：
+     - 方法名中的下划线 `_` 会被转换为斜杠 `/`
+     - 例如：`API_relay_` 方法将映射到 `/API/relay/*` 路径
+   - 如果方法名以下划线结尾，表示这是一个通配符路径，可以匹配后续任意路径
+
+2. 手动注册：插件实现 `IRegisterHandler` 接口进行手动注册
+   - 小写开头的方法无法被反射获取，需要通过手动注册方式
+   - 手动注册可以使用路径参数（如 `:id`）
+   - 更灵活的路由规则配置
+
+示例代码：
+```go
+// 反射注册示例
+type YourPlugin struct {
+    // ...
+}
+
+// 大写开头，可以被反射获取
+// 自动映射到 /API/relay/*
+func (p *YourPlugin) API_relay_(w http.ResponseWriter, r *http.Request) {
+    // 处理通配符路径的请求
+}
+
+// 小写开头，无法被反射获取，需要手动注册
+func (p *YourPlugin) handleUserRequest(w http.ResponseWriter, r *http.Request) {
+    // 处理带参数的请求
+}
+
+// 手动注册示例
+func (p *YourPlugin) RegisterHandler() {
+    // 可以使用路径参数
+    engine.GET("/api/user/:id", p.handleUserRequest)
+}
+```
+
+## 中间件机制
+
+### 1. 添加中间件
+
+插件可以通过 `AddMiddleware` 方法添加全局中间件，用于处理所有 HTTP 请求。中间件按照添加顺序依次执行。
+
+示例代码：
+```go
+func (p *YourPlugin) OnInit() {
+    // 添加认证中间件
+    p.GetCommonConf().AddMiddleware(func(next http.HandlerFunc) http.HandlerFunc {
+        return func(w http.ResponseWriter, r *http.Request) {
+            // 在请求处理前执行
+            if !authenticate(r) {
+                http.Error(w, "Unauthorized", http.StatusUnauthorized)
+                return
+            }
+            // 调用下一个处理器
+            next(w, r)
+            // 在请求处理后执行
+        }
+    })
+}
+```
+
+### 2. 中间件使用场景
+
+- 认证和授权
+- 请求日志记录
+- CORS 处理
+- 请求限流
+- 响应头设置
+- 错误处理
+- 性能监控
+
+## 特殊协议支持
+
+### 1. HTTP-FLV
+
+- 支持 HTTP-FLV 直播流分发
+- 自动生成 FLV 头
+- 支持 GOP 缓存
+- 支持 WebSocket-FLV
+
+### 2. HTTP-MP4
+
+- 支持 HTTP-MP4 流分发
+- 支持 fMP4 文件分发
+
+### 3. HLS
+- 支持 HLS 协议
+- 支持 MPEG-TS 封装
+
+### 4. WebSocket
+
+- 支持自定义消息协议
+- 支持ws-flv
+- 支持ws-mp4

+# 日志机制
+
+Monibuca 使用 Go 标准库的 `slog` 作为日志系统，提供了结构化的日志记录功能。
+
+## 日志配置
+
+在全局配置中，可以通过 `LogLevel` 字段来设置日志级别。支持的日志级别有：
+
+- trace
+- debug
+- info 
+- warn
+- error
+
+配置示例:
+
+```yaml
+global:
+  LogLevel: "debug" # 设置日志级别为 debug
+```
+
+## 日志格式
+
+默认的日志格式包含以下信息：
+
+- 时间戳 (格式: HH:MM:SS.MICROSECONDS)
+- 日志级别
+- 日志消息
+- 结构化字段
+
+示例输出:
+```
+15:04:05.123456 INFO server started
+15:04:05.123456 ERROR failed to connect database dsn="xxx" type="mysql"
+```
+
+## 日志处理器
+
+Monibuca 使用 `console-slog` 作为默认的日志处理器，它提供了:
+
+1. 彩色输出支持
+2. 微秒级时间戳
+3. 结构化字段格式化
+
+### 多处理器支持
+
+Monibuca 实现了 `MultiLogHandler` 机制，支持同时使用多个日志处理器。这提供了以下优势：
+
+1. 可以同时将日志输出到多个目标（如控制台、文件、日志服务等）
+2. 支持动态添加和移除日志处理器
+3. 每个处理器可以有自己的日志级别设置
+4. 支持日志分组和属性继承
+
+通过插件系统，可以扩展多种日志处理方式，例如：
+
+- LogRotate 插件：支持日志文件轮转
+- VMLog 插件：支持将日志存储到 VictoriaMetrics 时序数据库
+
+## 在插件中使用日志
+
+每个插件都会继承服务器的日志配置。插件可以通过以下方式记录日志：
+
+```go
+plugin.Info("message", "key1", value1, "key2", value2)  // 记录 INFO 级别日志
+plugin.Debug("message", "key1", value1)                 // 记录 DEBUG 级别日志
+plugin.Warn("message", "key1", value1)                  // 记录 WARN 级别日志
+plugin.Error("message", "key1", value1)                 // 记录 ERROR 级别日志
+```
+
+## 日志初始化流程
+
+1. 服务器启动时创建默认的控制台日志处理器
+2. 从配置文件读取日志级别设置
+3. 应用日志级别配置
+4. 为每个插件设置继承的日志配置
+
+## 最佳实践
+
+1. 合理使用日志级别
+   - trace: 用于最详细的追踪信息
+   - debug: 用于调试信息
+   - info: 用于正常运行时的重要信息
+   - warn: 用于警告信息
+   - error: 用于错误信息
+
+2. 使用结构化字段
+   - 避免在消息中拼接变量
+   - 使用 key-value 对记录额外信息
+
+3. 错误处理
+   - 记录错误时包含完整的错误信息
+   - 添加相关的上下文信息
+
+示例:
+```go
+// 推荐
+s.Error("failed to connect database", "error", err, "dsn", dsn)
+
+// 不推荐
+s.Error("failed to connect database: " + err.Error())
+```
+
+## 扩展日志系统
+
+要扩展日志系统，可以通过以下方式：
+
+1. 实现自定义的 `slog.Handler` 接口
+2. 使用 `LogHandler.Add()` 方法添加新的处理器
+3. 可以通过插件系统提供更复杂的日志功能
+
+例如添加自定义日志处理器：
+
+```go
+type MyLogHandler struct {
+    slog.Handler
+}
+
+// 在插件初始化时添加处理器
+func (p *MyPlugin) OnInit() error {
+    handler := &MyLogHandler{}
+    p.Server.LogHandler.Add(handler)
+    return nil
+}
+```

+# 插件系统
+
+Monibuca 采用插件化架构设计，通过插件机制来扩展功能。插件系统是 Monibuca 的核心特性之一，它允许开发者以模块化的方式添加新功能，而不需要修改核心代码。
+
+## 插件生命周期
+
+插件系统具有完整的生命周期管理，主要包含以下阶段：
+
+### 1. 注册阶段
+
+插件通过 `InstallPlugin` 泛型函数进行注册，在此阶段会：
+
+- 创建插件元数据(PluginMeta)，包含：
+  - 插件名称：自动从插件结构体名称中提取(去除"Plugin"后缀)
+  - 插件版本：从调用者的文件路径或包路径中提取，如果无法提取则默认为"dev"
+  - 插件类型：通过反射获取插件结构体类型
+  
+- 注册可选功能：
+  - 退出处理器(OnExitHandler)
+  - 默认配置(DefaultYaml)
+  - 拉流器(Puller)
+  - 推流器(Pusher)
+  - 录制器(Recorder)
+  - 转换器(Transformer)
+  - 发布认证(AuthPublisher)
+  - 订阅认证(AuthSubscriber)
+  - gRPC服务(ServiceDesc)
+  - gRPC网关处理器(RegisterGRPCHandler)
+
+- 将插件元数据添加到全局插件列表中
+
+注册阶段是插件生命周期的第一个阶段，它为插件系统提供了插件的基本信息和功能定义，为后续的初始化和启动做准备。
+
+### 2. 初始化阶段 (Init)
+
+插件通过 `Plugin.Init` 方法进行初始化，此阶段包含以下步骤：
+
+1. 实例化检查
+   - 检查插件是否实现了 IPlugin 接口
+   - 通过反射获取插件实例
+
+2. 基础设置
+   - 设置插件元数据和服务器引用
+   - 配置插件日志记录器
+   - 设置插件名称和版本信息
+
+3. 环境检查
+   - 检查环境变量是否禁用插件(通过 {PLUGIN_NAME}_ENABLE=false)
+   - 检查全局禁用状态(DisableAll)
+   - 检查用户配置中的启用状态(enable)
+
+4. 配置加载
+   - 解析通用配置
+   - 加载默认YAML配置
+   - 合并用户配置
+   - 应用最终配置并记录
+
+5. 数据库初始化（如果需要）
+   - 检查数据库连接配置(DSN)
+   - 建立数据库连接
+   - 自动迁移数据库表结构(针对录制功能)
+
+6. 状态记录
+   - 记录插件版本
+   - 记录用户配置
+   - 设置日志级别
+   - 记录初始化状态
+
+如果在初始化过程中发生错误：
+- 插件将被标记为禁用状态
+- 记录禁用原因
+- 添加到已禁用插件列表
+
+初始化阶段为插件的运行准备必要的环境和资源，是确保插件正常运行的关键阶段。
+
+### 3. 启动阶段 (Start)
+
+插件通过 `Plugin.Start` 方法启动，此阶段按顺序执行以下操作：
+
+1. gRPC服务注册（如果配置）
+   - 注册gRPC服务
+   - 注册gRPC网关处理器
+   - 处理gRPC相关错误
+
+2. 插件管理
+   - 将插件添加到服务器的插件列表中
+   - 设置插件状态为运行中
+
+3. 网络监听初始化
+   - HTTP/HTTPS服务启动
+   - TCP/TLS服务启动（如果实现了ITCPPlugin接口）
+   - UDP服务启动（如果实现了IUDPPlugin接口）
+   - QUIC服务启动（如果实现了IQUICPlugin接口）
+
+4. 插件初始化回调
+   - 调用插件的OnInit方法
+   - 处理初始化错误
+
+5. 定时任务设置
+   - 配置服务器保活任务（如果启用）
+   - 设置其他定时任务
+
+如果在启动过程中发生错误：
+- 记录错误原因
+- 将插件标记为禁用状态
+- 停止后续启动步骤
+
+启动阶段是插件开始提供服务的关键阶段，此时插件完成了所有准备工作，可以开始处理业务逻辑。
+
+### 4. 停止阶段 (Stop)
+
+插件的停止阶段通过 `Plugin.OnStop` 方法和相关的停止处理逻辑实现，主要包含以下步骤：
+
+1. 停止服务
+   - 停止所有网络服务（HTTP/HTTPS/TCP/UDP/QUIC）
+   - 关闭所有网络连接
+   - 停止处理新的请求
+
+2. 资源清理
+   - 停止所有定时任务
+   - 关闭数据库连接（如果有）
+   - 清理临时文件和缓存
+
+3. 状态处理
+   - 更新插件状态为已停止
+   - 从服务器的活动插件列表中移除
+   - 触发停止事件通知
+
+4. 回调处理
+   - 调用插件自定义的OnStop方法
+   - 执行注册的停止回调函数
+   - 处理停止过程中的错误
+
+5. 连接处理
+   - 等待当前请求处理完成
+   - 优雅关闭现有连接
+   - 拒绝新的连接请求
+
+停止阶段的主要目标是确保插件能够安全、干净地停止运行，不影响系统的其他部分。
+
+### 5. 销毁阶段 (Destroy)
+
+插件的销毁阶段通过 `Plugin.Dispose` 方法实现，这是插件生命周期的最后阶段，主要包含以下步骤：
+
+1. 资源释放
+   - 调用插件的OnStop方法进行停止处理
+   - 从服务器的插件列表中移除
+   - 释放所有分配的系统资源
+
+2. 状态清理
+   - 清除插件的所有状态信息
+   - 重置插件的内部变量
+   - 清空插件的配置信息
+
+3. 连接断开
+   - 断开与其他插件的所有连接
+   - 清理插件间的依赖关系
+   - 移除事件监听器
+
+4. 数据清理
+   - 清理插件产生的临时数据
+   - 关闭并清理数据库连接
+   - 删除不再需要的文件
+
+5. 最终处理
+   - 执行注册的销毁回调函数
+   - 记录销毁日志
+   - 确保所有资源都被正确释放
+
+销毁阶段的主要目标是确保插件完全清理所有资源，不留下任何残留状态，防止内存泄漏和资源泄露。

+# 基于HLS v7的fMP4技术实现与应用
+
+## 作者前言
+
+作为Monibuca流媒体服务器的开发者，我们一直在寻求提供更高效、更灵活的流媒体解决方案。随着Web前端技术的发展，特别是Media Source Extensions (MSE) 的广泛应用，我们逐渐认识到传统的流媒体传输方案已难以满足现代应用的需求。在探索与实践中，我们发现fMP4(fragmented MP4)技术能够很好地连接传统媒体格式与现代Web技术，为用户提供更流畅的视频体验。
+
+Monibuca项目在MP4插件的实现中，我们面临着如何将已录制的MP4文件高效转换为支持MSE播放的格式这一挑战。通过深入研究HLS v7协议和fMP4容器格式，我们最终实现了一套完整的解决方案，支持MP4到fMP4的实时转换、多段MP4的无缝合并，以及针对前端MSE播放的优化。本文将分享我们在这一过程中的技术探索和实现思路。
+
+## 引言
+
+随着流媒体技术的发展，视频分发方式不断演进。从传统的整体式下载到渐进式下载，再到现在广泛使用的自适应码率流媒体技术，每一步演进都极大地提升了用户体验。本文将探讨基于HLS v7的fMP4（fragmented MP4）技术实现，以及它如何与现代Web前端中的媒体源扩展（Media Source Extensions, MSE）结合，打造高效流畅的视频播放体验。
+
+## HLS协议演进与fMP4的引入
+
+### 传统HLS与其局限性
+
+HTTP Live Streaming (HLS)是由Apple公司开发的HTTP自适应比特率流媒体通信协议。在早期版本中，HLS主要使用TS(Transport Stream)切片作为媒体容器格式。虽然TS格式具有良好的容错性和流式传输特性，但也存在一些局限性：
+
+1. 相比于MP4等容器格式，TS文件体积较大
+2. 每个TS切片都需要包含完整的初始化信息，导致冗余
+3. 与Web技术栈的其他部分集成度不高
+
+### HLS v7与fMP4
+
+HLS v7版本引入了对fMP4(fragmented MP4)切片的支持，这是HLS协议的一个重大进步。fMP4作为媒体容器格式相比TS具有以下优势：
+
+1. 文件体积更小，传输效率更高
+2. 与DASH等其他流媒体协议共享相同的底层容器格式，有利于统一技术栈
+3. 更好地支持现代编解码器
+4. 与MSE(Media Source Extensions)有更好的兼容性
+
+在HLS v7中，通过在播放列表中使用`#EXT-X-MAP`标签指定初始化片段，可以实现fMP4切片的无缝播放。
+
+## MP4文件结构与fMP4的基本原理
+
+### 传统MP4结构
+
+传统的MP4文件遵循ISO Base Media File Format(ISO BMFF)规范，主要由以下几个部分组成：
+
+1. **ftyp** (File Type Box): 指示文件的格式和兼容性信息
+2. **moov** (Movie Box): 包含媒体的元数据信息，如轨道信息、编解码器参数等
+3. **mdat** (Media Data Box): 包含实际的媒体数据
+
+在传统MP4中，`moov`通常位于文件开头或结尾，包含了整个视频的所有元信息和索引数据。这种结构对于流式传输不友好，因为播放器需要先获取完整的`moov`才能开始播放。
+
+以下是MP4文件的box结构示意图：
+
+```mermaid
+graph TD
+    MP4[MP4文件] --> FTYP[ftyp box]
+    MP4 --> MOOV[moov box]
+    MP4 --> MDAT[mdat box]
+    MOOV --> MVHD[mvhd: 电影头信息]
+    MOOV --> TRAK1[trak: 视频轨道]
+    MOOV --> TRAK2[trak: 音频轨道]
+    TRAK1 --> TKHD1[tkhd: 轨道头信息]
+    TRAK1 --> MDIA1[mdia: 媒体信息]
+    TRAK2 --> TKHD2[tkhd: 轨道头信息]
+    TRAK2 --> MDIA2[mdia: 媒体信息]
+    MDIA1 --> MDHD1[mdhd: 媒体头信息]
+    MDIA1 --> HDLR1[hdlr: 处理器信息]
+    MDIA1 --> MINF1[minf: 媒体信息容器]
+    MDIA2 --> MDHD2[mdhd: 媒体头信息]
+    MDIA2 --> HDLR2[hdlr: 处理器信息]
+    MDIA2 --> MINF2[minf: 媒体信息容器]
+    MINF1 --> STBL1[stbl: 采样表]
+    MINF2 --> STBL2[stbl: 采样表]
+    STBL1 --> STSD1[stsd: 采样描述]
+    STBL1 --> STTS1[stts: 时间戳信息]
+    STBL1 --> STSC1[stsc: 块到采样映射]
+    STBL1 --> STSZ1[stsz: 采样大小]
+    STBL1 --> STCO1[stco: 块偏移]
+    STBL2 --> STSD2[stsd: 采样描述]
+    STBL2 --> STTS2[stts: 时间戳信息]
+    STBL2 --> STSC2[stsc: 块到采样映射]
+    STBL2 --> STSZ2[stsz: 采样大小]
+    STBL2 --> STCO2[stco: 块偏移]
+```
+
+### fMP4的结构特点
+
+fMP4(fragmented MP4)对传统MP4格式进行了重构，主要特点是：
+
+1. 将媒体数据分割成多个片段(fragments)
+2. 每个片段包含自己的元数据和媒体数据
+3. 文件结构更适合流式传输
+
+fMP4的主要组成部分：
+
+1. **ftyp**: 与传统MP4相同，位于文件开头
+2. **moov**: 包含整体的轨道信息，但不包含具体的样本信息
+3. **moof** (Movie Fragment Box): 包含特定片段的元数据
+4. **mdat**: 包含与前面的moof相关联的媒体数据
+
+以下是fMP4文件的box结构示意图：
+
+```mermaid
+graph TD
+    FMP4[fMP4文件] --> FTYP[ftyp box]
+    FMP4 --> MOOV[moov box]
+    FMP4 --> MOOF1[moof 1: 片段1元数据]
+    FMP4 --> MDAT1[mdat 1: 片段1媒体数据]
+    FMP4 --> MOOF2[moof 2: 片段2元数据]
+    FMP4 --> MDAT2[mdat 2: 片段2媒体数据]
+    FMP4 -.- MOOFN[moof n: 片段n元数据]
+    FMP4 -.- MDATN[mdat n: 片段n媒体数据]
+    
+    MOOV --> MVHD[mvhd: 电影头信息]
+    MOOV --> MVEX[mvex: 电影扩展]
+    MOOV --> TRAK1[trak: 视频轨道]
+    MOOV --> TRAK2[trak: 音频轨道]
+    
+    MVEX --> TREX1[trex 1: 轨道扩展]
+    MVEX --> TREX2[trex 2: 轨道扩展]
+    
+    MOOF1 --> MFHD1[mfhd: 片段头]
+    MOOF1 --> TRAF1[traf: 轨道片段]
+    
+    TRAF1 --> TFHD1[tfhd: 轨道片段头]
+    TRAF1 --> TFDT1[tfdt: 轨道片段基准时间]
+    TRAF1 --> TRUN1[trun: 轨道运行信息]
+```
+
+这种结构允许播放器在接收到初始的`ftyp`和`moov`后，可以立即开始处理后续接收到的`moof`+`mdat`片段，非常适合流式传输和实时播放。
+
+## MP4到fMP4的转换原理
+
+MP4到fMP4的转换过程可以通过以下时序图来说明：
+
+```mermaid
+sequenceDiagram
+    participant MP4 as 源MP4文件
+    participant Demuxer as MP4解析器
+    participant Muxer as fMP4封装器
+    participant fMP4 as 目标fMP4文件
+    
+    MP4->>Demuxer: 读取MP4文件
+    Note over Demuxer: 解析文件结构
+    Demuxer->>Demuxer: 提取ftyp信息
+    Demuxer->>Demuxer: 解析moov box
+    Demuxer->>Demuxer: 提取tracks信息<br>(视频、音频轨道)
+    Demuxer->>Muxer: 传递tracks元数据
+    
+    Muxer->>fMP4: 写入ftyp box
+    Muxer->>Muxer: 创建适合流式传输的moov
+    Muxer->>Muxer: 添加mvex扩展
+    Muxer->>fMP4: 写入moov box
+    
+    loop 对每个媒体样本
+        Demuxer->>MP4: 读取样本数据
+        Demuxer->>Muxer: 传递样本
+        Muxer->>Muxer: 创建moof box<br>(包含时间和位置信息)
+        Muxer->>Muxer: 创建mdat box<br>(包含实际媒体数据)
+        Muxer->>fMP4: 写入moof+mdat对
+    end
+    
+    Note over fMP4: 完成转换
+```
+
+从上图可以看出，转换过程主要包含三个关键步骤：
+
+1. **解析源MP4文件**：读取并解析原始MP4文件的结构，提取出视频轨、音频轨的相关信息，包括编解码器类型、帧率、分辨率等元数据。
+
+2. **创建fMP4的初始化部分**：构建文件头和初始化部分，包括ftyp和moov box，它们作为初始化段(initialization segment)，包含了解码器需要的所有信息，但不包含实际的媒体样本数据。
+
+3. **为每个样本创建片段**：逐个读取原始MP4中的样本数据，然后为每个样本（或一组样本）创建对应的moof和mdat box对。
+
+这种转换方式使得原本只适合下载后播放的MP4文件变成了适合流式传输的fMP4格式。
+
+## MP4多段合并技术
+
+### 用户需求：时间范围录像下载
+
+在视频监控、课程回放和直播录制等场景中，用户经常需要下载特定时间范围内的录像内容。例如，一个安防系统的操作员可能只需要导出包含特定事件的视频片段，或者一个教育平台的学生可能只想下载课程中的重点部分。然而，由于系统通常按照固定时长（如30分钟或1小时）或特定事件（如直播开始/结束）来分割录制文件，用户需要的时间范围往往横跨多个独立的MP4文件。
+
+在Monibuca项目中，我们针对这一需求，开发了基于时间范围查询和多文件合并的解决方案。用户只需指定所需内容的起止时间，系统会：
+
+1. 查询数据库，找出所有与指定时间范围重叠的录像文件
+2. 从每个文件中提取相关的时间片段
+3. 将这些片段无缝合并为单个下载文件
+
+这种方式极大地提升了用户体验，使其能够精确获取所需内容，而不必下载和浏览大量无关的视频内容。
+
+### 数据库设计与时间范围查询
+
+为支持时间范围查询，我们的录像文件元数据在数据库中包含以下关键字段：
+
+- 流路径（StreamPath）：标识视频源
+- 开始时间（StartTime）：录像片段的开始时间
+- 结束时间（EndTime）：录像片段的结束时间
+- 文件路径（FilePath）：实际录像文件的存储位置
+- 文件类型（Type）：文件格式，如"mp4"
+
+当用户请求特定时间范围的录像时，系统执行类似以下的查询：
+
+```sql
+SELECT * FROM record_streams 
+WHERE stream_path = ? AND type = 'mp4' 
+AND start_time <= ? AND end_time >= ?
+```
+
+这将返回所有与请求时间范围有交集的录像片段，然后系统需要从中提取相关部分并合并。
+
+### 多段MP4合并的技术挑战
+
+合并多个MP4文件并非简单的文件拼接，而是需要处理以下技术挑战：
+
+1. **时间戳连续性**：确保合并后视频的时间戳连续，没有跳跃或重叠
+2. **编解码一致性**：处理不同MP4文件可能使用不同编码参数的情况
+3. **元数据合并**：正确合并各文件的moov box信息
+4. **精确剪切**：从每个文件中精确提取用户指定时间范围的内容
+
+在实际应用中，我们实现了两种合并策略：普通MP4合并和fMP4合并。这两种策略各有优势，适用于不同的应用场景。
+
+### 普通MP4合并流程
+
+```mermaid
+sequenceDiagram
+    participant User as 用户
+    participant API as API服务
+    participant DB as 数据库
+    participant MP4s as 多个MP4文件
+    participant Muxer as MP4封装器
+    participant Output as 输出MP4文件
+    
+    User->>API: 请求时间范围录像<br>(stream, startTime, endTime)
+    API->>DB: 查询指定范围的录像记录
+    DB-->>API: 返回符合条件的录像列表
+    
+    loop 对每个MP4文件
+        API->>MP4s: 读取文件
+        MP4s->>Muxer: 解析文件结构
+        Muxer->>Muxer: 解析轨道信息
+        Muxer->>Muxer: 提取媒体样本
+        Muxer->>Muxer: 调整时间戳保持连续性
+        Muxer->>Muxer: 记录样本信息和偏移量
+        Note over Muxer: 跳过时间范围外的样本
+    end
+    
+    Muxer->>Output: 写入ftyp box
+    Muxer->>Output: 写入调整后的样本数据
+    Muxer->>Muxer: 创建包含所有样本信息的moov
+    Muxer->>Output: 写入合并后的moov box
+    Output-->>User: 向用户提供合并后的文件
+```
+
+这种方式下，合并过程主要是将不同MP4文件的媒体样本连续排列，并调整时间戳确保连续性。最后，重新生成一个包含所有样本信息的`moov` box。这种方法的优点是兼容性好，几乎所有播放器都能正常播放合并后的文件，适合用于下载和离线播放场景。
+
+特别值得注意的是，在代码实现中，我们会处理参数中时间范围与实际录像时间的重叠关系，只提取用户真正需要的内容：
+
+```go
+if i == 0 {
+    startTimestamp := startTime.Sub(stream.StartTime).Milliseconds()
+    var startSample *box.Sample
+    if startSample, err = demuxer.SeekTime(uint64(startTimestamp)); err != nil {
+        tsOffset = 0
+        continue
+    }
+    tsOffset = -int64(startSample.Timestamp)
+}
+
+// 在最后一个文件中，超出结束时间的帧会被跳过
+if i == streamCount-1 && int64(sample.Timestamp) > endTime.Sub(stream.StartTime).Milliseconds() {
+    break
+}
+```
+
+### fMP4合并流程
+
+```mermaid
+sequenceDiagram
+    participant User as 用户
+    participant API as API服务
+    participant DB as 数据库
+    participant MP4s as 多个MP4文件
+    participant Muxer as fMP4封装器
+    participant Output as 输出fMP4文件
+    
+    User->>API: 请求时间范围录像<br>(stream, startTime, endTime)
+    API->>DB: 查询指定范围的录像记录
+    DB-->>API: 返回符合条件的录像列表
+    
+    Muxer->>Output: 写入ftyp box
+    Muxer->>Output: 写入初始moov box<br>(包含mvex)
+    
+    loop 对每个MP4文件
+        API->>MP4s: 读取文件
+        MP4s->>Muxer: 解析文件结构
+        Muxer->>Muxer: 解析轨道信息
+        Muxer->>Muxer: 提取媒体样本
+        
+        loop 对每个样本
+            Note over Muxer: 检查样本是否在目标时间范围内
+            Muxer->>Muxer: 调整时间戳
+            Muxer->>Muxer: 创建moof+mdat对
+            Muxer->>Output: 写入moof+mdat对
+        end
+    end
+    
+    Output-->>User: 向用户提供合并后的文件
+```
+
+fMP4的合并更加灵活，每个样本都被封装成独立的`moof`+`mdat`片段，保持了可独立解码的特性，更有利于流式传输和随机访问。这种方式特别适合与MSE和HLS结合，为实时流媒体播放提供支持，让用户能够在浏览器中直接高效地播放合并后的内容，而无需等待整个文件下载完成。
+
+### 合并中的编解码兼容性处理
+
+在多段录像合并过程中，我们面临的一个关键挑战是处理不同文件可能存在的编码参数差异。例如，在长时间录制过程中，摄像头可能因环境变化调整了视频分辨率，或者编码器可能重新初始化导致编码参数变化。
+
+为了解决这一问题，Monibuca实现了一个智能的轨道版本管理系统，通过比较编码器特定数据(ExtraData)来识别变化：
+
+```mermaid
+sequenceDiagram
+    participant Muxer as 合并器
+    participant Track as 轨道管理器
+    participant History as 轨道历史版本
+
+    loop 对每个新轨道
+        Muxer->>Track: 检查轨道编码参数
+        Track->>History: 比较已有轨道版本
+        alt 发现匹配的轨道版本
+            History-->>Track: 返回现有轨道
+            Track-->>Muxer: 使用已有轨道
+        else 无匹配版本
+            Track->>Track: 创建新轨道版本
+            Track->>History: 添加到历史版本库
+            Track-->>Muxer: 使用新轨道
+        end
+    end
+```
+
+这种设计确保了即使原始录像中存在编码参数变化，合并后的文件也能保持正确的解码参数，为用户提供流畅的播放体验。
+
+### 性能优化
+
+在处理大型视频文件或大量并发请求时，合并过程的性能是一个重要考量。我们采取了以下优化措施：
+
+1. **流式处理**：逐帧处理样本，避免将整个文件加载到内存
+2. **并行处理**：对多个独立任务(如文件解析)采用并行处理
+3. **智能缓存**：缓存常用的编码参数和文件元数据
+4. **按需读取**：仅读取和处理目标时间范围内的样本
+
+这些优化使得系统能够高效处理大规模的录像合并请求，即使是跨越数小时或数天的长时间录像，也能在合理的时间内完成处理。
+
+多段MP4合并功能极大地增强了Monibuca作为流媒体服务器的灵活性和用户体验，使用户能够精确获取所需的录像内容，无论原始录像如何分段存储。
+
+## 媒体源扩展(MSE)与fMP4的兼容实现
+
+### MSE技术概述
+
+媒体源扩展(Media Source Extensions, MSE)是一种JavaScript API，允许网页开发者直接操作媒体流数据。它使得自定义的自适应比特率流媒体播放器可以完全在浏览器中实现，无需依赖外部插件。
+
+MSE的核心工作原理是：
+1. 创建一个MediaSource对象
+2. 创建一个或多个SourceBuffer对象
+3. 将媒体片段追加到SourceBuffer中
+4. 浏览器负责解码和播放这些片段
+
+### fMP4与MSE的完美适配
+
+fMP4格式与MSE有着天然的兼容性，主要体现在：
+
+1. fMP4的每个片段都可以独立解码
+2. 初始化段和媒体段的清晰分离符合MSE的缓冲区管理模型
+3. 时间戳的精确控制使得无缝拼接成为可能
+
+以下时序图展示了fMP4如何与MSE配合工作：
+
+```mermaid
+sequenceDiagram
+    participant Client as 浏览器客户端
+    participant Server as 服务器
+    participant MSE as MediaSource API
+    participant Video as HTML5 Video元素
+

+    Client->>MSE: 创建MediaSource对象
+    Client->>Video: 设置video.src = URL.createObjectURL(mediaSource)
+    MSE-->>Client: sourceopen事件
+    
+    Client->>MSE: 创建SourceBuffer
+    Client->>Server: 请求初始化段(ftyp+moov)
+    Server-->>Client: 返回初始化段
+    Client->>MSE: appendBuffer(初始化段)
+    
+    loop 播放过程
+        Client->>Server: 请求媒体段(moof+mdat)
+        Server-->>Client: 返回媒体段
+        Client->>MSE: appendBuffer(媒体段)
+        MSE-->>Video: 解码并渲染帧
+    end
+```
+
+在Monibuca的实现中，我们针对MSE进行了特殊优化：为每一帧创建独立的moof和mdat。这种实现方式尽管会增加一些开销，但提供了极高的灵活性，特别适合于低延迟的实时流媒体场景和精确的帧级操作。
+
+## HLS与fMP4在实际应用中的集成
+
+在实际应用中，我们将fMP4技术与HLS v7协议结合，实现了基于时间范围的点播功能。系统可以根据用户指定的时间范围，从数据库中查找对应的MP4记录，然后生成fMP4格式的HLS播放列表：
+
+```mermaid
+sequenceDiagram
+    participant Client as 客户端
+    participant Server as HLS服务
+    participant DB as 数据库
+    participant MP4Plugin as MP4插件
+    
+    Client->>Server: 请求fMP4.m3u8<br>带时间范围参数
+    Server->>DB: 查询指定时间范围的MP4记录
+    DB-->>Server: 返回记录列表
+    
+    Server->>Server: 创建HLS v7播放列表<br>Version: 7
+    loop 对每个记录
+        Server->>Server: 计算时长
+        Server->>Server: 添加媒体片段URL<br>/mp4/download/{stream}.fmp4?id={id}
+    end
+    
+    Server->>Server: 添加#EXT-X-ENDLIST标记
+    Server-->>Client: 返回HLS播放列表
+    
+    loop 对每个片段
+        Client->>MP4Plugin: 请求fMP4片段
+        MP4Plugin->>MP4Plugin: 转换为fMP4格式
+        MP4Plugin-->>Client: 返回fMP4片段
+    end
+```
+
+通过这种方式，我们在保持兼容现有HLS客户端的同时，利用了fMP4格式的优势，提供了更高效的流媒体服务。
+
+## 结论
+
+fMP4作为一种现代媒体容器格式，结合了MP4的高效压缩和流媒体传输的灵活性，非常适合现代Web应用中的视频分发需求。通过与HLS v7和MSE技术的结合，可以实现更高效、更灵活的流媒体服务。
+
+在Monibuca项目的实践中，我们通过实现MP4到fMP4的转换、多段MP4文件的合并，以及针对MSE优化fMP4片段生成，成功构建了一套完整的流媒体解决方案。这些技术的应用使得我们的系统能够提供更好的用户体验，包括更快的启动时间、更平滑的画质切换以及更低的带宽消耗。
+
+随着视频技术的不断发展，fMP4作为连接传统媒体格式与现代Web技术的桥梁，将继续在流媒体领域发挥重要作用。而Monibuca项目也将持续探索和优化这一技术，为用户提供更优质的流媒体服务。

+# Etcd 集成测试说明
+
+## 1. 概述
+
+本测试方案旨在验证 Cluster 插件对 etcd 的集成功能，包括：
+
+1. 内嵌 etcd 服务器的启动和运行
+2. 节点信息在 etcd 中的存储和同步
+3. 流信息在 etcd 中的存储和同步
+4. etcd 键值操作的 API 接口
+5. etcd 变更监控 (Watcher) 功能
+6. 节点故障和恢复过程中的数据一致性
+
+## 2. 测试环境
+
+测试环境由以下组件组成：
+
+1. **管理节点** (etcd-node1): 运行内嵌 etcd 服务器，作为集群的中心节点
+2. **工作节点** (etcd-node2, etcd-node3): 连接到 etcd 存储，提供媒体处理能力
+3. **测试客户端**: 通过 Node.js 脚本和 CDP 与集群交互
+
+### 2.1 节点配置
+
+我们提供了三个节点的配置文件：
+
+- `etcd-node1.yaml`: 管理节点，启用内嵌 etcd 服务器
+- `etcd-node2.yaml`: 工作节点，连接到 etcd
+- `etcd-node3.yaml`: 工作节点，连接到 etcd 并启用 watcher
+
+每个配置文件都包含了对应节点的 etcd 相关配置，以满足不同的测试场景。
+
+## 3. 测试用例
+
+### 3.1 集群状态测试
+
+验证集群是否通过 etcd 正确形成，所有节点是否能够注册到 etcd 并被其他节点发现。
+
+**预期结果**: 所有节点都能够正确注册和发现，集群状态 API 返回完整的节点列表。
+
+### 3.2 Etcd 键值存储测试
+
+测试通过 API 接口操作 etcd 键值存储的基本功能。
+
+**测试步骤**:
+1. 设置测试键值
+2. 获取并验证键值
+3. 删除键值
+4. 确认键值已删除
+
+**预期结果**: 所有键值操作都能正确执行，数据在所有节点间同步。
+
+### 3.3 节点故障和恢复测试
+
+测试当节点发生故障并恢复后，其在 etcd 中的状态是否能够正确更新。
+
+**测试步骤**:
+1. 确认所有节点在线
+2. 关闭一个工作节点
+3. 验证节点状态更新为离线
+4. 重启工作节点
+5. 验证节点状态恢复为在线
+
+**预期结果**: 节点状态在 etcd 中正确更新，故障节点被标记为离线，恢复后自动标记为在线。
+
+### 3.4 Etcd Watcher 测试
+
+测试 etcd 的变更监控功能，验证一个节点的变更能否被其他节点通过 watcher 及时感知。
+
+**测试步骤**:
+1. 在节点1上设置键值
+2. 验证节点3是否能通过 watcher 获取到更新
+
+**预期结果**: 节点3能够实时接收键值更新，证明 watcher 功能正常工作。
+
+## 4. 运行测试
+
+### 4.1 前置条件
+
+- Node.js 环境
+- Go 环境
+- Chrome 浏览器（远程调试端口 9222）
+
+### 4.2 测试命令
+
+```bash
+# 进入测试目录
+cd example/cluster-test
+
+# 安装依赖
+pnpm install
+
+# 运行 etcd 测试
+node etcd-test-runner.js
+```
+
+### 4.3 测试输出
+
+测试脚本将输出详细的测试过程和结果，包括：
+
+- 服务器启动信息
+- 每个测试用例的执行过程
+- 测试通过或失败的标记
+- 最终的测试结果摘要
+
+## 5. 注意事项
+
+1. 确保测试前没有其他 etcd 实例在运行，特别是使用相同的端口
+2. 测试过程中可能需要较长时间，因为 etcd 启动和同步需要一定时间
+3. 如果测试失败，请检查日志输出以了解详细错误信息
+4. 测试完成后，脚本会自动清理资源，如果由于某些原因未能清理，请手动终止 Go 进程
+
+## 6. 扩展测试
+
+如需添加更多测试场景，可以修改 `etcd-test-runner.js` 文件，添加新的测试用例函数，并将其添加到测试列表中。

+[![CI status](https://github.com/cyrus-and/chrome-remote-interface/actions/workflows/ci.yml/badge.svg)](https://github.com/cyrus-and/chrome-remote-interface/actions?query=workflow:CI)
+
+[Chrome Debugging Protocol] interface that helps to instrument Chrome (or any
+other suitable [implementation](#implementations)) by providing a simple
+abstraction of commands and notifications using a straightforward JavaScript
+API.
+
+## Sample API usage
+
+The following snippet loads `https://github.com` and dumps every request made:
+
+```js
+const CDP = require('chrome-remote-interface');
+
+async function example() {
+    let client;
+    try {
+        // connect to endpoint
+        client = await CDP();
+        // extract domains
+        const {Network, Page} = client;
+        // setup handlers
+        Network.requestWillBeSent((params) => {
+            console.log(params.request.url);
+        });
+        // enable events then start!
+        await Network.enable();
+        await Page.enable();
+        await Page.navigate({url: 'https://github.com'});
+        await Page.loadEventFired();
+    } catch (err) {
+        console.error(err);
+    } finally {
+        if (client) {
+            await client.close();
+        }
+    }
+}
+
+example();
+```

+The meaning of *target* varies according to the implementation, for example,
+each Chrome tab represents a target whereas for Node.js a target is the
+currently inspected script.
+
+## Setup
+
+An instance of either Chrome itself or another implementation needs to be
+running on a known port in order to use this module (defaults to
+`localhost:9222`).
+
+### Chrome/Chromium
+
+#### Desktop
+
+Start Chrome with the `--remote-debugging-port` option, for example:
+
+    google-chrome --remote-debugging-port=9222
+
+##### Headless
+
+Since version 59, additionally use the `--headless` option, for example:
+
+    google-chrome --headless --remote-debugging-port=9222
+
+#### Android
+
+Plug the device and make sure to authorize the connection from the device itself. Then
+enable the port forwarding, for example:
+
+    adb -d forward tcp:9222 localabstract:chrome_devtools_remote
+
+After that you should be able to use `http://127.0.0.1:9222` as usual, but note that in
+Android, Chrome does not have its own protocol available, so a local version must be used.
+See [here](#chrome-debugging-protocol-versions) for more information.
+
+##### WebView
+
+In order to be inspectable, a WebView must
+be [configured for debugging][webview] and the corresponding process ID must be
+known. There are several ways to obtain it, for example:
+
+    adb shell grep -a webview_devtools_remote /proc/net/unix
+
+Finally, port forwarding can be enabled as follows:
+
+    adb forward tcp:9222 localabstract:webview_devtools_remote_<pid>
+
+[webview]: https://developers.google.com/web/tools/chrome-devtools/remote-debugging/webviews#configure_webviews_for_debugging
+
+### Opera
+
+Start Opera with the `--remote-debugging-port` option, for example:
+
+    opera --remote-debugging-port=9222
+
+### Node.js
+
+Start Node.js with the `--inspect` option, for example:
+
+    node --inspect=9222 script.js
+
+### Safari (iOS)
+
+Install and run the [iOS WebKit Debug Proxy][iwdp]. Then use it with the `local`
+option set to `true` to use the local version of the protocol or pass a custom
+descriptor upon connection (`protocol` option).
+
+[iwdp]: https://github.com/google/ios-webkit-debug-proxy
+
+### Edge
+
+Start Edge with the `--devtools-server-port` option, for example:
+
+    MicrosoftEdge.exe --devtools-server-port 9222 about:blank
+
+Please find more information [here][edge-devtools].
+
+[edge-devtools]: https://docs.microsoft.com/en-us/microsoft-edge/devtools-protocol/
+
+### Firefox (Nightly)
+
+Start Firefox with the `--remote-debugging-port` option, for example:
+
+    firefox --remote-debugging-port 9222
+
+Bear in mind that this is an experimental feature of Firefox.
+
+## Bundled client
+
+This module comes with a bundled client application that can be used to
+interactively control a remote instance.
+
+### Target management
+
+The bundled client exposes subcommands to interact with the HTTP frontend
+(e.g., [List](#cdplistoptions-callback), [New](#cdpnewoptions-callback), etc.),
+run with `--help` to display the list of available options.
+
+Here are some examples:
+
+```js
+$ chrome-remote-interface new 'http://example.com'
+{
+    "description": "",
+    "devtoolsFrontendUrl": "/devtools/inspector.html?ws=localhost:9222/devtools/page/b049bb56-de7d-424c-a331-6ae44cf7ae01",
+    "id": "b049bb56-de7d-424c-a331-6ae44cf7ae01",
+    "thumbnailUrl": "/thumb/b049bb56-de7d-424c-a331-6ae44cf7ae01",
+    "title": "",
+    "type": "page",
+    "url": "http://example.com/",
+    "webSocketDebuggerUrl": "ws://localhost:9222/devtools/page/b049bb56-de7d-424c-a331-6ae44cf7ae01"
+}
+$ chrome-remote-interface close 'b049bb56-de7d-424c-a331-6ae44cf7ae01'
+```
+
+### Inspection
+
+Using the `inspect` subcommand it is possible to perform [command execution](#clientdomainmethodparams-callback)
+and [event binding](#clientdomaineventcallback) in a REPL fashion that provides completion.
+
+Here is a sample session:
+
+```js
+$ chrome-remote-interface inspect
+>>> Runtime.evaluate({expression: 'window.location.toString()'})
+{ result: { type: 'string', value: 'about:blank' } }
+>>> Page.enable()
+{}
+>>> Page.loadEventFired(console.log)
+[Function]
+>>> Page.navigate({url: 'https://github.com'})
+{ frameId: 'E1657E22F06E6E0BE13DFA8130C20298',
+  loaderId: '439236ADE39978F98C20E8939A32D3A5' }
+>>> { timestamp: 7454.721299 } // from Page.loadEventFired
+>>> Runtime.evaluate({expression: 'window.location.toString()'})
+{ result: { type: 'string', value: 'https://github.com/' } }
+```
+
+Additionally there are some custom commands available:
+
+```js
+>>> .help
+[...]
+.reset    Remove all the registered event handlers
+.target   Display the current target
+```
+
+## Embedded documentation
+
+In both the REPL and the regular API every object of the protocol is *decorated*
+with the meta information found within the descriptor. In addition The
+`category` field is added, which determines if the member is a `command`, an
+`event` or a `type`.
+
+For example to learn how to call `Page.navigate`:
+
+```js
+>>> Page.navigate
+{ [Function]
+  category: 'command',
+  parameters: { url: { type: 'string', description: 'URL to navigate the page to.' } },
+  returns:
+   [ { name: 'frameId',
+       '$ref': 'FrameId',
+       hidden: true,
+       description: 'Frame id that will be navigated.' } ],
+  description: 'Navigates current page to the given URL.',
+  handlers: [ 'browser', 'renderer' ] }
+```
+
+To learn about the parameters returned by the `Network.requestWillBeSent` event:
+
+```js
+>>> Network.requestWillBeSent
+{ [Function]
+  category: 'event',
+  description: 'Fired when page is about to send HTTP request.',
+  parameters:
+   { requestId: { '$ref': 'RequestId', description: 'Request identifier.' },
+     frameId:
+      { '$ref': 'Page.FrameId',
+        description: 'Frame identifier.',
+        hidden: true },
+     loaderId: { '$ref': 'LoaderId', description: 'Loader identifier.' },
+     documentURL:
+      { type: 'string',
+        description: 'URL of the document this request is loaded for.' },
+     request: { '$ref': 'Request', description: 'Request data.' },
+     timestamp: { '$ref': 'Timestamp', description: 'Timestamp.' },
+     wallTime:
+      { '$ref': 'Timestamp',
+        hidden: true,
+        description: 'UTC Timestamp.' },
+     initiator: { '$ref': 'Initiator', description: 'Request initiator.' },
+     redirectResponse:
+      { optional: true,
+        '$ref': 'Response',
+        description: 'Redirect response data.' },
+     type:
+      { '$ref': 'Page.ResourceType',
+        optional: true,
+        hidden: true,
+        description: 'Type of this resource.' } } }
+```
+
+To inspect the `Network.Request` (note that unlike commands and events, types
+are named in upper camel case) type:
+
+```js
+>>> Network.Request
+{ category: 'type',
+  id: 'Request',
+  type: 'object',
+  description: 'HTTP request data.',
+  properties:
+   { url: { type: 'string', description: 'Request URL.' },
+     method: { type: 'string', description: 'HTTP request method.' },
+     headers: { '$ref': 'Headers', description: 'HTTP request headers.' },
+     postData:
+      { type: 'string',
+        optional: true,
+        description: 'HTTP POST request data.' },
+     mixedContentType:
+      { optional: true,
+        type: 'string',
+        enum: [Object],
+        description: 'The mixed content status of the request, as defined in http://www.w3.org/TR/mixed-content/' },
+     initialPriority:
+      { '$ref': 'ResourcePriority',
+        description: 'Priority of the resource request at the time request is sent.' } } }
+```
+
+## Chrome Debugging Protocol versions
+
+By default `chrome-remote-interface` *asks* the remote instance to provide its
+own protocol.
+
+This behavior can be changed by setting the `local` option to `true`
+upon [connection](#cdpoptions-callback), in which case the [local version] of
+the protocol descriptor is used. This file is manually updated from time to time
+using `scripts/update-protocol.sh` and pushed to this repository.
+
+To further override the above behavior there are basically two options:
+
+- pass a custom protocol descriptor upon [connection](#cdpoptions-callback)
+  (`protocol` option);
+
+- use the *raw* version of the [commands](#clientsendmethod-params-callback)
+  and [events](#event-domainmethod) interface to use bleeding-edge features that
+  do not appear in the [local version] of the protocol descriptor;
+
+[local version]: lib/protocol.json
+
+## Browser usage
+
+This module is able to run within a web context, with obvious limitations
+though, namely external HTTP requests
+([List](#cdplistoptions-callback), [New](#cdpnewoptions-callback), etc.) cannot
+be performed directly, for this reason the user must provide a global
+`criRequest` in order to use them:
+
+```js
+function criRequest(options, callback) {}
+```
+
+`options` is the same object used by the Node.js `http` module and `callback` is
+a function taking two arguments: `err` (JavaScript `Error` object or `null`) and
+`data` (string result).
+
+### Using [webpack](https://webpack.github.io/)
+
+It just works, simply require this module:
+
+```js
+const CDP = require('chrome-remote-interface');
+```
+
+### Using *vanilla* JavaScript
+
+To generate a JavaScript file that can be used with a `<script>` element:
+
+1. run `npm install` from the root directory;
+
+2. manually run webpack with:
+
+        TARGET=var npm run webpack
+
+3. use as:
+
+    ```html
+    <script>
+      function criRequest(options, callback) { /*...*/ }
+    </script>
+    <script src="chrome-remote-interface.js"></script>
+    ```
+
+## TypeScript Support
+
+[TypeScript][] definitions are kindly provided by [Khairul Azhar Kasmiran][] and [Seth Westphal][], and can be installed from [DefinitelyTyped][]:

+
+## API
+
+The API consists of three parts:
+
+- *DevTools* methods (for those [implementations](#implementations) that support
+  them, e.g., [List](#cdplistoptions-callback), [New](#cdpnewoptions-callback),
+  etc.);
+
+- [connection](#cdpoptions-callback) establishment;
+
+- the actual [protocol interaction](#class-cdp).
+
+### CDP([options], [callback])
+
+Connects to a remote instance using the [Chrome Debugging Protocol].
+
+`options` is an object with the following optional properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL
+  before that a request happens. Defaults to the identity function;
+- `target`: determines which target this client should attach to. The behavior
+  changes according to the type:
+
+  - a `function` that takes the array returned by the `List` method and returns
+    a target or its numeric index relative to the array;
+  - a target `object` like those returned by the `New` and `List` methods;
+  - a `string` representing the raw WebSocket URL, in this case `host` and
+    `port` are not used to fetch the target list, yet they are used to complete
+    the URL if relative;
+  - a `string` representing the target id.
+
+  Defaults to a function which returns the first available target according to
+  the implementation (note that at most one connection can be established to the
+  same target);
+- `protocol`: [Chrome Debugging Protocol] descriptor object. Defaults to use the
+  protocol chosen according to the `local` option;
+- `local`: a boolean indicating whether the protocol must be fetched *remotely*
+  or if the local version must be used. It has no effect if the `protocol`
+  option is set. Defaults to `false`.
+
+These options are also valid properties of all the instances of the `CDP`
+class. In addition to that, the `webSocketUrl` field contains the currently used
+WebSocket URL.
+
+`callback` is a listener automatically added to the `connect` event of the
+returned `EventEmitter`. When `callback` is omitted a `Promise` object is
+returned which becomes fulfilled if the `connect` event is triggered and
+rejected if the `error` event is triggered.
+
+The `EventEmitter` supports the following events:
+
+#### Event: 'connect'
+
+```js
+function (client) {}
+```
+
+Emitted when the connection to the WebSocket is established.
+
+`client` is an instance of the `CDP` class.
+
+#### Event: 'error'
+
+```js
+function (err) {}
+```
+
+Emitted when `http://host:port/json` cannot be reached or if it is not possible
+to connect to the WebSocket.
+
+`err` is an instance of `Error`.
+
+### CDP.Protocol([options], [callback])
+
+Fetch the [Chrome Debugging Protocol] descriptor.
+
+`options` is an object with the following optional properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL
+  before that a request happens. Defaults to the identity function;
+- `local`: a boolean indicating whether the protocol must be fetched *remotely*
+  or if the local version must be returned. Defaults to `false`.
+
+`callback` is executed when the protocol is fetched, it gets the following
+arguments:
+
+- `err`: a `Error` object indicating the success status;
+- `protocol`: the [Chrome Debugging Protocol] descriptor.
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.Protocol((err, protocol) => {
+    if (!err) {
+        console.log(JSON.stringify(protocol, null, 4));
+    }
+});
+```
+
+### CDP.List([options], [callback])
+
+Request the list of the available open targets/tabs of the remote instance.
+
+`options` is an object with the following optional properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL
+  before that a request happens. Defaults to the identity function.
+
+`callback` is executed when the list is correctly received, it gets the
+following arguments:
+
+- `err`: a `Error` object indicating the success status;
+- `targets`: the array returned by `http://host:port/json/list` containing the
+  target list.
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.List((err, targets) => {
+    if (!err) {
+        console.log(targets);
+    }
+});
+```
+
+### CDP.New([options], [callback])
+
+Create a new target/tab in the remote instance.
+
+`options` is an object with the following optional properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL
+  before that a request happens. Defaults to the identity function;
+- `url`: URL to load in the new target/tab. Defaults to `about:blank`.
+
+`callback` is executed when the target is created, it gets the following
+arguments:
+
+- `err`: a `Error` object indicating the success status;
+- `target`: the object returned by `http://host:port/json/new` containing the
+  target.
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.New((err, target) => {
+    if (!err) {
+        console.log(target);
+    }
+});
+```
+
+### CDP.Activate([options], [callback])
+
+Activate an open target/tab of the remote instance.
+
+`options` is an object with the following properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL
+  before that a request happens. Defaults to the identity function;
+- `id`: Target id. Required, no default.
+
+`callback` is executed when the response to the activation request is
+received. It gets the following arguments:
+
+- `err`: a `Error` object indicating the success status;
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.Activate({id: 'CC46FBFA-3BDA-493B-B2E4-2BE6EB0D97EC'}, (err) => {
+    if (!err) {
+        console.log('target is activated');
+    }
+});
+```
+
+### CDP.Close([options], [callback])

+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;
+- `alterPath`: a `function` taking and returning the path fragment of a URL

+
+`callback` is executed when the response to the close request is received. It
+gets the following arguments:
+
+- `err`: a `Error` object indicating the success status;
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.Close({id: 'CC46FBFA-3BDA-493B-B2E4-2BE6EB0D97EC'}, (err) => {
+    if (!err) {
+        console.log('target is closing');
+    }
+});
+```
+
+Note that the callback is fired when the target is *queued* for removal, but the
+actual removal will occur asynchronously.
+
+### CDP.Version([options], [callback])
+
+Request version information from the remote instance.
+
+`options` is an object with the following optional properties:
+
+- `host`: HTTP frontend host. Defaults to `localhost`;
+- `port`: HTTP frontend port. Defaults to `9222`;
+- `secure`: HTTPS/WSS frontend. Defaults to `false`;
+- `useHostName`: do not perform a DNS lookup of the host. Defaults to `false`;

+
+`callback` is executed when the version information is correctly received, it
+gets the following arguments:
+
+- `err`: a `Error` object indicating the success status;
+- `info`: a JSON object returned by `http://host:port/json/version` containing
+  the version information.
+
+When `callback` is omitted a `Promise` object is returned.
+
+For example:
+
+```js
+const CDP = require('chrome-remote-interface');
+CDP.Version((err, info) => {
+    if (!err) {
+        console.log(info);
+    }
+});
+```
+
+### Class: CDP
+
+#### Event: 'event'
+
+```js
+function (message) {}
+```
+
+Emitted when the remote instance sends any notification through the WebSocket.
+
+`message` is the object received, it has the following properties:
+
+- `method`: a string describing the notification (e.g.,
+  `'Network.requestWillBeSent'`);
+- `params`: an object containing the payload;
+- `sessionId`: an optional string representing the session identifier.
+
+Refer to the [Chrome Debugging Protocol] specification for more information.
+
+For example:
+
+```js
+client.on('event', (message) => {
+    if (message.method === 'Network.requestWillBeSent') {
+        console.log(message.params);
+    }
+});
+```
+
+#### Event: '`<domain>`.`<method>`'
+
+```js
+function (params, sessionId) {}
+```
+
+Emitted when the remote instance sends a notification for `<domain>.<method>`
+through the WebSocket.
+
+`params` is an object containing the payload.
+
+`sessionId` is an optional string representing the session identifier.
+
+This is just a utility event which allows to easily listen for specific
+notifications (see [`'event'`](#event-event)), for example:
+
+```js
+client.on('Network.requestWillBeSent', console.log);
+```
+
+Additionally, the equivalent `<domain>.on('<method>', ...)` syntax is available, for example:
+
+```js
+client.Network.on('requestWillBeSent', console.log);
+```
+
+#### Event: '`<domain>`.`<method>`.`<sessionId>`'
+
+```js
+function (params, sessionId) {}
+```
+
+Equivalent to the following but only for those events belonging to the given `session`:
+
+```js
+client.on('<domain>.<event>', callback);
+```
+
+#### Event: 'ready'
+
+```js
+function () {}
+```
+
+Emitted every time that there are no more pending commands waiting for a
+response from the remote instance. The interaction is asynchronous so the only
+way to serialize a sequence of commands is to use the callback provided by
+the [`send`](#clientsendmethod-params-callback) method. This event acts as a
+barrier and it is useful to avoid the *callback hell* in certain simple
+situations.
+
+Users are encouraged to extensively check the response of each method and should
+prefer the promises API when dealing with complex asynchronous program flows.
+
+For example to load a URL only after having enabled the notifications of both
+`Network` and `Page` domains:
+
+```js
+client.Network.enable();
+client.Page.enable();
+client.once('ready', () => {
+    client.Page.navigate({url: 'https://github.com'});
+});
+```
+
+In this particular case, not enforcing this kind of serialization may cause that
+the remote instance does not properly deliver the desired notifications the
+client.
+
+
+#### Event: 'disconnect'
+
+```js
+function () {}
+```
+
+Emitted when the instance closes the WebSocket connection.
+
+This may happen for example when the user opens DevTools or when the tab is
+closed.
+
+#### client.send(method, [params], [sessionId], [callback])
+
+Issue a command to the remote instance.
+
+`method` is a string describing the command.
+
+`params` is an object containing the payload.
+
+`sessionId` is a string representing the session identifier.
+
+`callback` is executed when the remote instance sends a response to this
+command, it gets the following arguments:
+
+- `error`: a boolean value indicating the success status, as reported by the
+  remote instance;
+- `response`: an object containing either the response (`result` field, if
+  `error === false`) or the indication of the error (`error` field, if `error
+  === true`).
+
+When `callback` is omitted a `Promise` object is returned instead, with the
+fulfilled/rejected states implemented according to the `error` parameter. The
+`Error` object returned contains two additional parameters: `request` and
+`response` which contain the raw massages, useful for debugging purposes. In
+case of low-level WebSocket errors, the `error` parameter contains the
+originating `Error` object and no `response` is returned.
+
+Note that the field `id` mentioned in the [Chrome Debugging Protocol]
+specification is managed internally and it is not exposed to the user.
+
+For example:
+
+```js
+client.send('Page.navigate', {url: 'https://github.com'}, console.log);
+```
+
+#### client.`<domain>`.`<method>`([params], [sessionId], [callback])
+
+Just a shorthand for:
+
+```js
+client.send('<domain>.<method>', params, sessionId, callback);
+```
+
+For example:
+
+```js
+client.Page.navigate({url: 'https://github.com'}, console.log);
+```
+
+#### client.`<domain>`.`<event>`([sessionId], [callback])
+
+Just a shorthand for:
+
+```js
+client.on('<domain>.<event>[.<sessionId>]', callback);
+```
+
+When `callback` is omitted the event is registered only once and a `Promise`
+object is returned. Notice though that in this case the optional `sessionId` usually passed to `callback` is not returned.
+
+When `callback` is provided, it returns a function that can be used to
+unsubscribe `callback` from the event, it can be useful when anonymous functions
+are used as callbacks.
+
+For example:
+
+```js
+const unsubscribe = client.Network.requestWillBeSent((params, sessionId) => {
+    console.log(params.request.url);
+});
+unsubscribe();
+```
+
+#### client.close([callback])
+
+Close the connection to the remote instance.
+
+`callback` is executed when the WebSocket is successfully closed.
+
+When `callback` is omitted a `Promise` object is returned.
+
+#### client['`<domain>`.`<name>`']
+
+Just a shorthand for:
+
+```js
+client.<domain>.<name>
+```
+
+Where `<name>` can be a command, an event, or a type.
+
+## FAQ
+
+### Invoking `Domain.methodOrEvent` I obtain `Domain.methodOrEvent is not a function`
+
+This means that you are trying to use a method or an event that are not present
+in the protocol descriptor that you are using.
+
+If the protocol is fetched from Chrome directly, then it means that this version
+of Chrome does not support that feature. The solution is to update it.
+
+If you are using a local or custom version of the protocol, then it means that
+the version is obsolete. The solution is to provide an up-to-date one, or if you
+are using the protocol embedded in chrome-remote-interface, make sure to be
+running the latest version of this module. In case the embedded protocol is
+obsolete, please [file an issue](https://github.com/cyrus-and/chrome-remote-interface/issues/new).
+
+See [here](#chrome-debugging-protocol-versions) for more information.
+
+### Invoking `Domain.method` I obtain `Domain.method wasn't found`
+
+This means that you are providing a custom or local protocol descriptor
+(`CDP({protocol: customProtocol})`) which declares `Domain.method` while the
+Chrome version that you are using does not support it.
+
+To inspect the currently available protocol descriptor use:
+
+```
+$ chrome-remote-interface inspect
+```
+
+See [here](#chrome-debugging-protocol-versions) for more information.
+
+### Why my program stalls or behave unexpectedly if I run Chrome in a Docker container?
+
+This happens because the size of `/dev/shm` is set to 64MB by default in Docker
+and may not be enough for Chrome to navigate certain web pages.
+
+You can change this value by running your container with, say,
+`--shm-size=256m`.
+
+### Using `Runtime.evaluate` with `awaitPromise: true` I sometimes obtain `Error: Promise was collected`
+
+This is thrown by `Runtime.evaluate` when the browser-side promise gets
+*collected* by the Chrome's garbage collector, this happens when the whole
+JavaScript execution environment is invalidated, e.g., a when page is navigated
+or reloaded while a promise is still waiting to be resolved.
+
+Here is an example:
+
+```
+$ chrome-remote-interface inspect
+>>> Runtime.evaluate({expression: `new Promise(() => {})`, awaitPromise: true})
+>>> Page.reload() // then wait several seconds
+{ result: {} }
+{ error: { code: -32000, message: 'Promise was collected' } }
+```
+
+To fix this, just make sure there are no pending promises before closing,
+reloading, etc. a page.
+
+### How does this compare to Puppeteer?
+
+[Puppeteer] is an additional high-level API built upon the [Chrome Debugging
+Protocol] which, among the other things, may start and use a bundled version of
+Chromium instead of the one installed on your system. Use it if its API meets
+your needs as it would probably be easier to work with.
+
+chrome-remote-interface instead is just a general purpose 1:1 Node.js binding
+for the [Chrome Debugging Protocol]. Use it if you need all the power of the raw
+protocol, e.g., to implement your own high-level API.
+
+See [#240] for a more thorough discussion.

+
+  The complete solution for [node.js](http://nodejs.org) command-line interfaces, inspired by Ruby's [commander](https://github.com/commander-rb/commander).  
+  [API documentation](http://tj.github.com/commander.js/)
+
+
+## Installation
+
+    $ npm install commander --save
+
+## Option parsing
+
+ Options with commander are defined with the `.option()` method, also serving as documentation for the options. The example below parses args and options from `process.argv`, leaving remaining args as the `program.args` array which were not consumed by options.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-p, --peppers', 'Add peppers')
+  .option('-P, --pineapple', 'Add pineapple')
+  .option('-b, --bbq-sauce', 'Add bbq sauce')
+  .option('-c, --cheese [type]', 'Add the specified type of cheese [marble]', 'marble')
+  .parse(process.argv);
+
+console.log('you ordered a pizza with:');
+if (program.peppers) console.log('  - peppers');
+if (program.pineapple) console.log('  - pineapple');
+if (program.bbqSauce) console.log('  - bbq');
+console.log('  - %s cheese', program.cheese);
+```
+
+ Short flags may be passed as a single arg, for example `-abc` is equivalent to `-a -b -c`. Multi-word options such as "--template-engine" are camel-cased, becoming `program.templateEngine` etc.
+
+
+## Coercion
+
+```js
+function range(val) {
+  return val.split('..').map(Number);
+}
+
+function list(val) {
+  return val.split(',');
+}
+
+function collect(val, memo) {
+  memo.push(val);
+  return memo;
+}
+
+function increaseVerbosity(v, total) {
+  return total + 1;
+}
+
+program
+  .version('0.1.0')
+  .usage('[options] <file ...>')
+  .option('-i, --integer <n>', 'An integer argument', parseInt)
+  .option('-f, --float <n>', 'A float argument', parseFloat)
+  .option('-r, --range <a>..<b>', 'A range', range)
+  .option('-l, --list <items>', 'A list', list)
+  .option('-o, --optional [value]', 'An optional value')
+  .option('-c, --collect [value]', 'A repeatable value', collect, [])
+  .option('-v, --verbose', 'A value that can be increased', increaseVerbosity, 0)
+  .parse(process.argv);
+
+console.log(' int: %j', program.integer);
+console.log(' float: %j', program.float);
+console.log(' optional: %j', program.optional);
+program.range = program.range || [];
+console.log(' range: %j..%j', program.range[0], program.range[1]);
+console.log(' list: %j', program.list);
+console.log(' collect: %j', program.collect);
+console.log(' verbosity: %j', program.verbose);
+console.log(' args: %j', program.args);
+```
+
+## Regular Expression
+```js
+program
+  .version('0.1.0')
+  .option('-s --size <size>', 'Pizza size', /^(large|medium|small)$/i, 'medium')
+  .option('-d --drink [drink]', 'Drink', /^(coke|pepsi|izze)$/i)
+  .parse(process.argv);
+  
+console.log(' size: %j', program.size);
+console.log(' drink: %j', program.drink);
+```
+
+## Variadic arguments
+
+ The last argument of a command can be variadic, and only the last argument.  To make an argument variadic you have to
+ append `...` to the argument name.  Here is an example:
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .command('rmdir <dir> [otherDirs...]')
+  .action(function (dir, otherDirs) {
+    console.log('rmdir %s', dir);
+    if (otherDirs) {
+      otherDirs.forEach(function (oDir) {
+        console.log('rmdir %s', oDir);
+      });
+    }
+  });
+
+program.parse(process.argv);
+```
+
+ An `Array` is used for the value of a variadic argument.  This applies to `program.args` as well as the argument passed
+ to your action as demonstrated above.
+
+## Specify the argument syntax
+
+```js
+#!/usr/bin/env node
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .arguments('<cmd> [env]')
+  .action(function (cmd, env) {
+     cmdValue = cmd;
+     envValue = env;
+  });
+
+program.parse(process.argv);
+
+if (typeof cmdValue === 'undefined') {
+   console.error('no command given!');
+   process.exit(1);
+}
+console.log('command:', cmdValue);
+console.log('environment:', envValue || "no environment given");
+```
+Angled brackets (e.g. `<cmd>`) indicate required input. Square brackets (e.g. `[env]`) indicate optional input.
+
+## Git-style sub-commands
+
+```js
+// file: ./examples/pm
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .command('install [name]', 'install one or more packages')
+  .command('search [query]', 'search with optional query')
+  .command('list', 'list packages installed', {isDefault: true})
+  .parse(process.argv);
+```
+
+When `.command()` is invoked with a description argument, no `.action(callback)` should be called to handle sub-commands, otherwise there will be an error. This tells commander that you're going to use separate executables for sub-commands, much like `git(1)` and other popular tools.  
+The commander will try to search the executables in the directory of the entry script (like `./examples/pm`) with the name `program-command`, like `pm-install`, `pm-search`.
+
+Options can be passed with the call to `.command()`. Specifying `true` for `opts.noHelp` will remove the option from the generated help output. Specifying `true` for `opts.isDefault` will run the subcommand if no other subcommand is specified.
+
+If the program is designed to be installed globally, make sure the executables have proper modes, like `755`.
+
+### `--harmony`
+
+You can enable `--harmony` option in two ways:
+* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. Note some os version don’t support this pattern.
+* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
+
+## Automated --help
+
+ The help information is auto-generated based on the information commander already knows about your program, so the following `--help` info is for free:
+
+```  
+ $ ./examples/pizza --help
+
+   Usage: pizza [options]
+
+   An application for pizzas ordering
+
+   Options:
+
+     -h, --help           output usage information
+     -V, --version        output the version number
+     -p, --peppers        Add peppers
+     -P, --pineapple      Add pineapple
+     -b, --bbq            Add bbq sauce
+     -c, --cheese <type>  Add the specified type of cheese [marble]
+     -C, --no-cheese      You do not want any cheese
+
+```
+
+## Custom help
+
+ You can display arbitrary `-h, --help` information
+ by listening for "--help". Commander will automatically
+ exit once you are done so that the remainder of your program
+ does not execute causing undesired behaviours, for example
+ in the following executable "stuff" will not output when
+ `--help` is used.
+
+```js
+#!/usr/bin/env node
+
+/**
+ * Module dependencies.
+ */
+
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-f, --foo', 'enable some foo')
+  .option('-b, --bar', 'enable some bar')
+  .option('-B, --baz', 'enable some baz');
+
+// must be before .parse() since
+// node's emit() is immediate
+
+program.on('--help', function(){
+  console.log('  Examples:');
+  console.log('');
+  console.log('    $ custom-help --help');
+  console.log('    $ custom-help -h');
+  console.log('');
+});
+
+program.parse(process.argv);
+
+console.log('stuff');
+```
+
+Yields the following help output when `node script-name.js -h` or `node script-name.js --help` are run:
+
+```
+
+Usage: custom-help [options]
+
+Options:
+
+  -h, --help     output usage information
+  -V, --version  output the version number
+  -f, --foo      enable some foo
+  -b, --bar      enable some bar
+  -B, --baz      enable some baz
+
+Examples:
+
+  $ custom-help --help
+  $ custom-help -h
+
+```
+
+## .outputHelp(cb)
+
+Output help information without exiting.
+Optional callback cb allows post-processing of help text before it is displayed.
+
+If you want to display help by default (e.g. if no command was provided), you can use something like:
+
+```js
+var program = require('commander');
+var colors = require('colors');
+
+program
+  .version('0.1.0')
+  .command('getstream [url]', 'get stream URL')
+  .parse(process.argv);
+
+  if (!process.argv.slice(2).length) {
+    program.outputHelp(make_red);
+  }
+
+function make_red(txt) {
+  return colors.red(txt); //display the help text in red on the console
+}
+```
+
+## .help(cb)
+
+  Output help information and exit immediately.
+  Optional callback cb allows post-processing of help text before it is displayed.
+
+## Examples
+
+```js
+var program = require('commander');
+
+program
+  .version('0.1.0')
+  .option('-C, --chdir <path>', 'change the working directory')
+  .option('-c, --config <path>', 'set config path. defaults to ./deploy.conf')
+  .option('-T, --no-tests', 'ignore test hook');
+
+program
+  .command('setup [env]')
+  .description('run setup commands for all envs')
+  .option("-s, --setup_mode [mode]", "Which setup mode to use")
+  .action(function(env, options){
+    var mode = options.setup_mode || "normal";
+    env = env || 'all';
+    console.log('setup for %s env(s) with %s mode', env, mode);
+  });
+
+program
+  .command('exec <cmd>')
+  .alias('ex')
+  .description('execute the given remote cmd')
+  .option("-e, --exec_mode <mode>", "Which exec mode to use")
+  .action(function(cmd, options){
+    console.log('exec "%s" using %s mode', cmd, options.exec_mode);
+  }).on('--help', function() {
+    console.log('  Examples:');
+    console.log();
+    console.log('    $ deploy exec sequential');
+    console.log('    $ deploy exec async');
+    console.log();
+  });
+
+program
+  .command('*')
+  .action(function(env){
+    console.log('deploying "%s"', env);
+  });
+
+program.parse(process.argv);
+```

+
+## Motivation
+
+Instead of implementing `XMLHttpRequest` in Node.js to run browser-specific [Fetch polyfill](https://github.com/github/fetch), why not go from native `http` to `fetch` API directly? Hence, `node-fetch`, minimal code for a `window.fetch` compatible API on Node.js runtime.
+
+See Matt Andrews' [isomorphic-fetch](https://github.com/matthew-andrews/isomorphic-fetch) or Leonardo Quixada's [cross-fetch](https://github.com/lquixada/cross-fetch) for isomorphic usage (exports `node-fetch` for server-side, `whatwg-fetch` for client-side).
+
+## Features
+
+- Stay consistent with `window.fetch` API.
+- Make conscious trade-off when following [WHATWG fetch spec][whatwg-fetch] and [stream spec](https://streams.spec.whatwg.org/) implementation details, document known differences.
+- Use native promise but allow substituting it with [insert your favorite promise library].
+- Use native Node streams for body on both request and response.
+- Decode content encoding (gzip/deflate) properly and convert string output (such as `res.text()` and `res.json()`) to UTF-8 automatically.
+- Useful extensions such as timeout, redirect limit, response size limit, [explicit errors](ERROR-HANDLING.md) for troubleshooting.
+
+## Difference from client-side fetch
+
+- See [Known Differences](LIMITS.md) for details.
+- If you happen to use a missing feature that `window.fetch` offers, feel free to open an issue.
+- Pull requests are welcomed too!
+
+## Installation
+
+Current stable release (`2.x`)
+
+```sh
+$ npm install node-fetch
+```
+
+## Loading and configuring the module
+We suggest you load the module via `require` until the stabilization of ES modules in node:
+```js
+const fetch = require('node-fetch');
+```
+
+If you are using a Promise library other than native, set it through `fetch.Promise`:
+```js
+const Bluebird = require('bluebird');
+
+fetch.Promise = Bluebird;
+```
+
+## Common Usage
+
+NOTE: The documentation below is up-to-date with `2.x` releases; see the [`1.x` readme](https://github.com/bitinn/node-fetch/blob/1.x/README.md), [changelog](https://github.com/bitinn/node-fetch/blob/1.x/CHANGELOG.md) and [2.x upgrade guide](UPGRADE-GUIDE.md) for the differences.
+
+#### Plain text or HTML
+```js
+fetch('https://github.com/')
+    .then(res => res.text())
+    .then(body => console.log(body));
+```
+
+#### JSON
+
+```js
+
+fetch('https://api.github.com/users/github')
+    .then(res => res.json())
+    .then(json => console.log(json));
+```
+
+#### Simple Post
+```js
+fetch('https://httpbin.org/post', { method: 'POST', body: 'a=1' })
+    .then(res => res.json()) // expecting a json response
+    .then(json => console.log(json));
+```
+
+#### Post with JSON
+
+```js
+const body = { a: 1 };
+
+fetch('https://httpbin.org/post', {
+        method: 'post',
+        body:    JSON.stringify(body),
+        headers: { 'Content-Type': 'application/json' },
+    })
+    .then(res => res.json())
+    .then(json => console.log(json));
+```
+
+#### Post with form parameters
+`URLSearchParams` is available in Node.js as of v7.5.0. See [official documentation](https://nodejs.org/api/url.html#url_class_urlsearchparams) for more usage methods.
+
+NOTE: The `Content-Type` header is only set automatically to `x-www-form-urlencoded` when an instance of `URLSearchParams` is given as such:
+
+```js
+const { URLSearchParams } = require('url');
+
+const params = new URLSearchParams();
+params.append('a', 1);
+
+fetch('https://httpbin.org/post', { method: 'POST', body: params })
+    .then(res => res.json())
+    .then(json => console.log(json));
+```
+
+#### Handling exceptions
+NOTE: 3xx-5xx responses are *NOT* exceptions and should be handled in `then()`; see the next section for more information.
+
+Adding a catch to the fetch promise chain will catch *all* exceptions, such as errors originating from node core libraries, network errors and operational errors, which are instances of FetchError. See the [error handling document](ERROR-HANDLING.md)  for more details.
+
+```js
+fetch('https://domain.invalid/')
+    .catch(err => console.error(err));
+```
+
+#### Handling client and server errors
+It is common to create a helper function to check that the response contains no client (4xx) or server (5xx) error responses:
+
+```js
+function checkStatus(res) {
+    if (res.ok) { // res.status >= 200 && res.status < 300
+        return res;
+    } else {
+        throw MyCustomError(res.statusText);
+    }
+}
+
+fetch('https://httpbin.org/status/400')
+    .then(checkStatus)
+    .then(res => console.log('will not get here...'))
+```
+
+## Advanced Usage
+
+#### Streams
+The "Node.js way" is to use streams when possible:
+
+```js
+fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
+    .then(res => {
+        const dest = fs.createWriteStream('./octocat.png');
+        res.body.pipe(dest);
+    });
+```
+
+In Node.js 14 you can also use async iterators to read `body`; however, be careful to catch
+errors -- the longer a response runs, the more likely it is to encounter an error.
+
+```js
+const fetch = require('node-fetch');
+const response = await fetch('https://httpbin.org/stream/3');
+try {
+	for await (const chunk of response.body) {
+		console.dir(JSON.parse(chunk.toString()));
+	}
+} catch (err) {
+	console.error(err.stack);
+}
+```
+
+In Node.js 12 you can also use async iterators to read `body`; however, async iterators with streams
+did not mature until Node.js 14, so you need to do some extra work to ensure you handle errors
+directly from the stream and wait on it response to fully close.
+
+```js
+const fetch = require('node-fetch');
+const read = async body => {
+    let error;
+    body.on('error', err => {
+        error = err;
+    });
+    for await (const chunk of body) {
+        console.dir(JSON.parse(chunk.toString()));
+    }
+    return new Promise((resolve, reject) => {
+        body.on('close', () => {
+            error ? reject(error) : resolve();
+        });
+    });
+};
+try {
+    const response = await fetch('https://httpbin.org/stream/3');
+    await read(response.body);
+} catch (err) {
+    console.error(err.stack);
+}
+```
+
+#### Buffer
+If you prefer to cache binary data in full, use buffer(). (NOTE: `buffer()` is a `node-fetch`-only API)
+
+```js
+const fileType = require('file-type');
+
+fetch('https://assets-cdn.github.com/images/modules/logos_page/Octocat.png')
+    .then(res => res.buffer())
+    .then(buffer => fileType(buffer))
+    .then(type => { /* ... */ });
+```
+
+#### Accessing Headers and other Meta data
+```js
+fetch('https://github.com/')
+    .then(res => {
+        console.log(res.ok);
+        console.log(res.status);
+        console.log(res.statusText);
+        console.log(res.headers.raw());
+        console.log(res.headers.get('content-type'));
+    });
+```
+
+#### Extract Set-Cookie Header
+
+Unlike browsers, you can access raw `Set-Cookie` headers manually using `Headers.raw()`. This is a `node-fetch` only API.
+
+```js
+fetch(url).then(res => {
+    // returns an array of values, instead of a string of comma-separated values
+    console.log(res.headers.raw()['set-cookie']);
+});
+```
+
+#### Post data using a file stream
+
+```js
+const { createReadStream } = require('fs');
+
+const stream = createReadStream('input.txt');
+
+fetch('https://httpbin.org/post', { method: 'POST', body: stream })
+    .then(res => res.json())
+    .then(json => console.log(json));
+```
+
+#### Post with form-data (detect multipart)
+
+```js
+const FormData = require('form-data');
+
+const form = new FormData();
+form.append('a', 1);
+
+fetch('https://httpbin.org/post', { method: 'POST', body: form })
+    .then(res => res.json())
+    .then(json => console.log(json));
+
+// OR, using custom headers
+// NOTE: getHeaders() is non-standard API
+
+const form = new FormData();
+form.append('a', 1);
+
+const options = {
+    method: 'POST',
+    body: form,
+    headers: form.getHeaders()
+}
+
+fetch('https://httpbin.org/post', options)
+    .then(res => res.json())
+    .then(json => console.log(json));
+```
+
+#### Request cancellation with AbortSignal
+
+> NOTE: You may cancel streamed requests only on Node >= v8.0.0
+
+You may cancel requests with `AbortController`. A suggested implementation is [`abort-controller`](https://www.npmjs.com/package/abort-controller).
+
+An example of timing out a request after 150ms could be achieved as the following:
+
+```js
+import AbortController from 'abort-controller';
+
+const controller = new AbortController();
+const timeout = setTimeout(
+  () => { controller.abort(); },
+  150,
+);
+
+fetch(url, { signal: controller.signal })
+  .then(res => res.json())
+  .then(
+    data => {
+      useData(data)
+    },
+    err => {
+      if (err.name === 'AbortError') {
+        // request was aborted
+      }
+    },
+  )
+  .finally(() => {
+    clearTimeout(timeout);
+  });
+```
+
+See [test cases](https://github.com/bitinn/node-fetch/blob/master/test/test.js) for more examples.
+
+
+## API
+
+### fetch(url[, options])
+
+- `url` A string representing the URL for fetching
+- `options` [Options](#fetch-options) for the HTTP(S) request
+- Returns: <code>Promise&lt;[Response](#class-response)&gt;</code>
+
+Perform an HTTP(S) fetch.
+
+`url` should be an absolute url, such as `https://example.com/`. A path-relative URL (`/file/under/root`) or protocol-relative URL (`//can-be-http-or-https.com/`) will result in a rejected `Promise`.
+
+<a id="fetch-options"></a>
+### Options
+
+The default values are shown after each option key.
+
+```js
+{
+    // These properties are part of the Fetch Standard
+    method: 'GET',
+    headers: {},        // request headers. format is the identical to that accepted by the Headers constructor (see below)
+    body: null,         // request body. can be null, a string, a Buffer, a Blob, or a Node.js Readable stream
+    redirect: 'follow', // set to `manual` to extract redirect headers, `error` to reject redirect
+    signal: null,       // pass an instance of AbortSignal to optionally abort requests
+
+    // The following properties are node-fetch extensions
+    follow: 20,         // maximum redirect count. 0 to not follow redirect
+    timeout: 0,         // req/res timeout in ms, it resets on redirect. 0 to disable (OS limit applies). Signal is recommended instead.
+    compress: true,     // support gzip/deflate content encoding. false to disable
+    size: 0,            // maximum response body size in bytes. 0 to disable
+    agent: null         // http(s).Agent instance or function that returns an instance (see below)
+}
+```
+
+##### Default Headers
+
+If no values are set, the following request headers will be sent automatically:
+
+Header              | Value
+------------------- | --------------------------------------------------------
+`Accept-Encoding`   | `gzip,deflate` _(when `options.compress === true`)_
+`Accept`            | `*/*`
+`Content-Length`    | _(automatically calculated, if possible)_
+`Transfer-Encoding` | `chunked` _(when `req.body` is a stream)_
+`User-Agent`        | `node-fetch/1.0 (+https://github.com/bitinn/node-fetch)`
+
+Note: when `body` is a `Stream`, `Content-Length` is not set automatically.
+
+##### Custom Agent
+
+The `agent` option allows you to specify networking related options which are out of the scope of Fetch, including and not limited to the following:
+
+- Support self-signed certificate
+- Use only IPv4 or IPv6
+- Custom DNS Lookup
+
+See [`http.Agent`](https://nodejs.org/api/http.html#http_new_agent_options) for more information.
+
+If no agent is specified, the default agent provided by Node.js is used. Note that [this changed in Node.js 19](https://github.com/nodejs/node/blob/4267b92604ad78584244488e7f7508a690cb80d0/lib/_http_agent.js#L564) to have `keepalive` true by default. If you wish to enable `keepalive` in an earlier version of Node.js, you can override the agent as per the following code sample. 
+
+In addition, the `agent` option accepts a function that returns `http`(s)`.Agent` instance given current [URL](https://nodejs.org/api/url.html), this is useful during a redirection chain across HTTP and HTTPS protocol.
+
+```js
+const httpAgent = new http.Agent({
+    keepAlive: true
+});
+const httpsAgent = new https.Agent({
+    keepAlive: true
+});
+
+const options = {
+    agent: function (_parsedURL) {
+        if (_parsedURL.protocol == 'http:') {
+            return httpAgent;
+        } else {
+            return httpsAgent;
+        }
+    }
+}
+```
+
+<a id="class-request"></a>
+### Class: Request
+
+An HTTP(S) request containing information about URL, method, headers, and the body. This class implements the [Body](#iface-body) interface.
+
+Due to the nature of Node.js, the following properties are not implemented at this moment:
+
+- `type`
+- `destination`
+- `referrer`
+- `referrerPolicy`
+- `mode`
+- `credentials`
+- `cache`
+- `integrity`
+- `keepalive`
+
+The following node-fetch extension properties are provided:
+
+- `follow`
+- `compress`
+- `counter`
+- `agent`
+
+See [options](#fetch-options) for exact meaning of these extensions.
+
+#### new Request(input[, options])
+
+<small>*(spec-compliant)*</small>
+
+- `input` A string representing a URL, or another `Request` (which will be cloned)
+- `options` [Options][#fetch-options] for the HTTP(S) request
+
+Constructs a new `Request` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Request/Request).
+
+In most cases, directly `fetch(url, options)` is simpler than creating a `Request` object.
+
+<a id="class-response"></a>
+### Class: Response
+
+An HTTP(S) response. This class implements the [Body](#iface-body) interface.
+
+The following properties are not implemented in node-fetch at this moment:
+
+- `Response.error()`
+- `Response.redirect()`
+- `type`
+- `trailer`
+
+#### new Response([body[, options]])
+
+<small>*(spec-compliant)*</small>
+
+- `body` A `String` or [`Readable` stream][node-readable]
+- `options` A [`ResponseInit`][response-init] options dictionary
+
+Constructs a new `Response` object. The constructor is identical to that in the [browser](https://developer.mozilla.org/en-US/docs/Web/API/Response/Response).
+
+Because Node.js does not implement service workers (for which this class was designed), one rarely has to construct a `Response` directly.
+
+#### response.ok
+
+<small>*(spec-compliant)*</small>
+
+Convenience property representing if the request ended normally. Will evaluate to true if the response status was greater than or equal to 200 but smaller than 300.
+
+#### response.redirected
+
+<small>*(spec-compliant)*</small>
+
+Convenience property representing if the request has been redirected at least once. Will evaluate to true if the internal redirect counter is greater than 0.
+
+<a id="class-headers"></a>
+### Class: Headers
+
+This class allows manipulating and iterating over a set of HTTP headers. All methods specified in the [Fetch Standard][whatwg-fetch] are implemented.
+
+#### new Headers([init])
+
+<small>*(spec-compliant)*</small>
+
+- `init` Optional argument to pre-fill the `Headers` object
+
+Construct a new `Headers` object. `init` can be either `null`, a `Headers` object, an key-value map object or any iterable object.
+
+```js
+// Example adapted from https://fetch.spec.whatwg.org/#example-headers-class
+
+const meta = {
+  'Content-Type': 'text/xml',
+  'Breaking-Bad': '<3'
+};
+const headers = new Headers(meta);
+
+// The above is equivalent to
+const meta = [
+  [ 'Content-Type', 'text/xml' ],
+  [ 'Breaking-Bad', '<3' ]
+];
+const headers = new Headers(meta);
+
+// You can in fact use any iterable objects, like a Map or even another Headers
+const meta = new Map();
+meta.set('Content-Type', 'text/xml');
+meta.set('Breaking-Bad', '<3');
+const headers = new Headers(meta);
+const copyOfHeaders = new Headers(headers);
+```
+
+<a id="iface-body"></a>
+### Interface: Body
+
+`Body` is an abstract interface with methods that are applicable to both `Request` and `Response` classes.
+
+The following methods are not yet implemented in node-fetch at this moment:
+
+- `formData()`
+
+#### body.body
+
+<small>*(deviation from spec)*</small>
+
+* Node.js [`Readable` stream][node-readable]
+
+Data are encapsulated in the `Body` object. Note that while the [Fetch Standard][whatwg-fetch] requires the property to always be a WHATWG `ReadableStream`, in node-fetch it is a Node.js [`Readable` stream][node-readable].
+
+#### body.bodyUsed
+
+<small>*(spec-compliant)*</small>
+
+* `Boolean`
+
+A boolean property for if this body has been consumed. Per the specs, a consumed body cannot be used again.
+
+#### body.arrayBuffer()
+#### body.blob()
+#### body.json()
+#### body.text()
+
+<small>*(spec-compliant)*</small>
+
+* Returns: <code>Promise</code>
+
+Consume the body and return a promise that will resolve to one of these formats.
+
+#### body.buffer()
+
+<small>*(node-fetch extension)*</small>
+
+* Returns: <code>Promise&lt;Buffer&gt;</code>
+
+Consume the body and return a promise that will resolve to a Buffer.
+
+#### body.textConverted()
+
+<small>*(node-fetch extension)*</small>
+
+* Returns: <code>Promise&lt;String&gt;</code>
+
+Identical to `body.text()`, except instead of always converting to UTF-8, encoding sniffing will be performed and text converted to UTF-8 if possible.
+
+(This API requires an optional dependency of the npm package [encoding](https://www.npmjs.com/package/encoding), which you need to install manually. `webpack` users may see [a warning message](https://github.com/bitinn/node-fetch/issues/412#issuecomment-379007792) due to this optional dependency.)

+# WebIDL Type Conversions on JavaScript Values
+
+This package implements, in JavaScript, the algorithms to convert a given JavaScript value according to a given [WebIDL](http://heycam.github.io/webidl/) [type](http://heycam.github.io/webidl/#idl-types).
+
+The goal is that you should be able to write code like
+
+```js
+const conversions = require("webidl-conversions");
+
+function doStuff(x, y) {
+    x = conversions["boolean"](x);
+    y = conversions["unsigned long"](y);
+    // actual algorithm code here
+}
+```
+
+and your function `doStuff` will behave the same as a WebIDL operation declared as
+
+```webidl
+void doStuff(boolean x, unsigned long y);
+```
+
+## API
+
+This package's main module's default export is an object with a variety of methods, each corresponding to a different WebIDL type. Each method, when invoked on a JavaScript value, will give back the new JavaScript value that results after passing through the WebIDL conversion rules. (See below for more details on what that means.) Alternately, the method could throw an error, if the WebIDL algorithm is specified to do so: for example `conversions["float"](NaN)` [will throw a `TypeError`](http://heycam.github.io/webidl/#es-float).
+
+## Status
+
+All of the numeric types are implemented (float being implemented as double) and some others are as well - check the source for all of them. This list will grow over time in service of the [HTML as Custom Elements](https://github.com/dglazkov/html-as-custom-elements) project, but in the meantime, pull requests welcome!
+
+I'm not sure yet what the strategy will be for modifiers, e.g. [`[Clamp]`](http://heycam.github.io/webidl/#Clamp). Maybe something like `conversions["unsigned long"](x, { clamp: true })`? We'll see.
+
+We might also want to extend the API to give better error messages, e.g. "Argument 1 of HTMLMediaElement.fastSeek is not a finite floating-point value" instead of "Argument is not a finite floating-point value." This would require passing in more information to the conversion functions than we currently do.
+
+## Background
+
+What's actually going on here, conceptually, is pretty weird. Let's try to explain.
+
+WebIDL, as part of its madness-inducing design, has its own type system. When people write algorithms in web platform specs, they usually operate on WebIDL values, i.e. instances of WebIDL types. For example, if they were specifying the algorithm for our `doStuff` operation above, they would treat `x` as a WebIDL value of [WebIDL type `boolean`](http://heycam.github.io/webidl/#idl-boolean). Crucially, they would _not_ treat `x` as a JavaScript variable whose value is either the JavaScript `true` or `false`. They're instead working in a different type system altogether, with its own rules.
+
+Separately from its type system, WebIDL defines a ["binding"](http://heycam.github.io/webidl/#ecmascript-binding) of the type system into JavaScript. This contains rules like: when you pass a JavaScript value to the JavaScript method that manifests a given WebIDL operation, how does that get converted into a WebIDL value? For example, a JavaScript `true` passed in the position of a WebIDL `boolean` argument becomes a WebIDL `true`. But, a JavaScript `true` passed in the position of a [WebIDL `unsigned long`](http://heycam.github.io/webidl/#idl-unsigned-long) becomes a WebIDL `1`. And so on.
+
+Finally, we have the actual implementation code. This is usually C++, although these days [some smart people are using Rust](https://github.com/servo/servo). The implementation, of course, has its own type system. So when they implement the WebIDL algorithms, they don't actually use WebIDL values, since those aren't "real" outside of specs. Instead, implementations apply the WebIDL binding rules in such a way as to convert incoming JavaScript values into C++ values. For example, if code in the browser called `doStuff(true, true)`, then the implementation code would eventually receive a C++ `bool` containing `true` and a C++ `uint32_t` containing `1`.
+
+The upside of all this is that implementations can abstract all the conversion logic away, letting WebIDL handle it, and focus on implementing the relevant methods in C++ with values of the correct type already provided. That is payoff of WebIDL, in a nutshell.
+
+And getting to that payoff is the goal of _this_ project—but for JavaScript implementations, instead of C++ ones. That is, this library is designed to make it easier for JavaScript developers to write functions that behave like a given WebIDL operation. So conceptually, the conversion pipeline, which in its general form is JavaScript values ↦ WebIDL values ↦ implementation-language values, in this case becomes JavaScript values ↦ WebIDL values ↦ JavaScript values. And that intermediate step is where all the logic is performed: a JavaScript `true` becomes a WebIDL `1` in an unsigned long context, which then becomes a JavaScript `1`.
+
+## Don't Use This
+
+Seriously, why would you ever use this? You really shouldn't. WebIDL is … not great, and you shouldn't be emulating its semantics. If you're looking for a generic argument-processing library, you should find one with better rules than those from WebIDL. In general, your JavaScript should not be trying to become more like WebIDL; if anything, we should fix WebIDL to make it more like JavaScript.
+
+The _only_ people who should use this are those trying to create faithful implementations (or polyfills) of web platform interfaces defined in WebIDL.
