 **Recommendations**
 
 - **Amcrest Doorbell** users may want to disable two way audio, because with an active stream you won't have a call button working. You need to add `#backchannel=0` to the end of your RTSP link in YAML config file
 - **Dahua Doorbell** users may want to change backchannel [audio codec](https://github.com/AlexxIT/go2rtc/issues/52)
+- **Reolink** users may want NOT to use RTSP protocol at all, some camera models have a very awful unusable stream implementation
 - **Ubiquiti UniFi** users may want to disable HTTPS verification. Use `rtspx://` prefix instead of `rtsps://`. And don't use `?enableSrtp` [suffix](https://github.com/AlexxIT/go2rtc/issues/81)
 - **TP-Link Tapo** users may skip login and password, because go2rtc support login [without them](https://drmnsamoliu.github.io/video.html)
 - If your camera has two RTSP links - you can add both of them as sources. This is useful when streams has different codecs, as example AAC audio with main stream and PCMU/PCMA audio with second stream
 - If the stream from your camera is glitchy, try using [ffmpeg source](#source-ffmpeg). It will not add CPU load if you won't use transcoding
 - If the stream from your camera is very glitchy, try to use transcoding with [ffmpeg source](#source-ffmpeg)
 
+**Other options**
+
+Format: `rtsp...#{param1}#{param2}#{param3}`

+- Add custom timeout `#timeout=30` (in seconds)
+- Ignore audio - `#media=video` or ignore video - `#media=audio` 
+- Ignore two way audio API `#backchannel=0` - important for some glitchy cameras

+- By default go2rtc will search config file `go2rtc.yaml` in current work directory
+- go2rtc support multiple config files:
+  - `go2rtc -c config1.yaml -c config2.yaml -c config3.yaml` 
+- go2rtc support inline config as multiple formats from command line:
+  - **YAML**: `go2rtc -c '{log: {format: text}}'`
+  - **JSON**: `go2rtc -c '{"log":{"format":"text"}}'`
+  - **key=value**: `go2rtc -c log.format=text`
+- Every next config will overwrite previous (but only defined params)
+
+```
+go2rtc -config "{log: {format: text}}" -config /config/go2rtc.yaml -config "{rtsp: {listen: ''}}" -config /usr/local/go2rtc/go2rtc.yaml
+```
+
+or simple version
+
+```
+go2rtc -c log.format=text -c /config/go2rtc.yaml -c rtsp.listen='' -c /usr/local/go2rtc/go2rtc.yaml
+```
+
+## Environment variables
+
+Also go2rtc support templates for using environment variables in any part of config:
+
+```yaml
+streams:
+  camera1: rtsp://rtsp:${CAMERA_PASSWORD}@192.168.1.123/av_stream/ch0
+
+rtsp:
+  username: ${RTSP_USER:admin}   # "admin" if env "RTSP_USER" not set
+  password: ${RTSP_PASS:secret}  # "secret" if env "RTSP_PASS" not set
+```
+
+## JSON Schema
+
+Editors like [GoLand](https://www.jetbrains.com/go/) and [VS Code](https://code.visualstudio.com/) supports autocomplete and syntax validation.
+
+```yaml
+# yaml-language-server: $schema=https://raw.githubusercontent.com/AlexxIT/go2rtc/master/website/schema.json

+- [language definition](https://expr.medv.io/docs/Language-Definition) - takes best from JS, Python, Jinja2 syntax
+- your expression should return a link of any supported source
+- expression supports multiple operation, but:
+  - all operations must be separated by a semicolon
+  - all operations, except the last one, must declare a new variable (`let s = "abc";`)
+  - the last operation should return a string
+- go2rtc supports additional functions:

+# GoPro
+
+Supported models: HERO9, HERO10, HERO11, HERO12.  
+Supported OS: Linux, Mac, Windows, [HassOS](https://www.home-assistant.io/installation/)
+
+The other camera models have different APIs. I will try to add them in the next versions.
+
+## Config
+
+- USB-connected cameras create a new network interface in the system
+- Linux users do not need to install anything
+- Windows users should install the [network driver](https://community.gopro.com/s/article/GoPro-Webcam)
+- if the camera is detected but the stream does not start - you need to disable firewall
+
+1. Discover camera address: WebUI > Add > GoPro
+2. Add camera to config
+
+```yaml
+streams:
+  hero12: gopro://172.20.100.51
+```
+
+## Useful links

+## Stream as ASCII to Terminal
+
+[![](https://img.youtube.com/vi/sHj_3h_sX7M/mqdefault.jpg)](https://www.youtube.com/watch?v=sHj_3h_sX7M)
+
+**Tips**
+
+- this feature works only with MJPEG codec (use transcoding)
+- choose a low frame rate (FPS)
+- choose the width and height to fit in your terminal
+- different terminals support different numbers of colours (8, 256, rgb)
+- escape text param with urlencode
+- you can stream any camera or file from a disc
+
+**go2rtc.yaml** - transcoding to MJPEG, terminal size - 210x59 (16/9), fps - 10
+
+```yaml
+streams:
+  gamazda: ffmpeg:gamazda.mp4#video=mjpeg#hardware#width=210#height=59#raw=-r 10
+```
+
+**API params**
+
+- `color` - foreground color, values: empty, `8`, `256`, `rgb`, [SGR](https://en.wikipedia.org/wiki/ANSI_escape_code)
+  - example: `30` (black), `37` (white), `38;5;226` (yellow)
+- `back` - background color, values: empty, `8`, `256`, `rgb`, [SGR](https://en.wikipedia.org/wiki/ANSI_escape_code)
+  - example: `40` (black), `47` (white), `48;5;226` (yellow)
+- `text` - character set, values: empty, one char, `block`, list of chars (in order of brightness)
+  - example: `%20` (space), `block` (keyword for block elements), `ox` (two chars)
+
+**Examples**
+
+```bash
+% curl "http://192.168.1.123:1984/api/stream.ascii?src=gamazda"
+% curl "http://192.168.1.123:1984/api/stream.ascii?src=gamazda&color=256"

+What you should to know about WebRTC:
+
+- It's almost always a **direct [peer-to-peer](https://en.wikipedia.org/wiki/Peer-to-peer) connection** from your browser to go2rtc app
+- When you use Home Assistant, Frigate, Nginx, Nabu Casa, Cloudflare and other software - they are only **involved in establishing** the connection, but they are **not involved in transferring** media data
+- WebRTC media cannot be transferred inside an HTTP connection
+- Usually, WebRTC uses random UDP ports on client and server side to establish a connection
+- Usually, WebRTC uses public [STUN](https://en.wikipedia.org/wiki/STUN) servers to establish a connection outside LAN, such servers are only needed to establish a connection and are not involved in data transfer
+- Usually, WebRTC will automatically discover all of your local addresses and all of your public addresses and try to establish a connection
+
+If an external connection via STUN is used:
+
+- Uses [UDP hole punching](https://en.wikipedia.org/wiki/UDP_hole_punching) technology to bypass NAT even if you not open your server to the World
+- For about 20% of users, the techology will not work because of the [Symmetric NAT](https://tomchen.github.io/symmetric-nat-test/)
+- UDP is not suitable for transmitting 2K and 4K high bitrate video over open networks because of the high loss rate
+
+## Default config
+
+```yaml
+webrtc:
+  listen: ":8555/tcp"
+  ice_servers:
+    - urls: [ "stun:stun.l.google.com:19302" ]
+```
+
+## Config
+
+**Important!** This example is not for copypasting!
+
+```yaml
+webrtc:
+  # fix local TCP or UDP or both ports for WebRTC media
+  listen: ":8555/tcp"        # address of your local server
+
+  # add additional host candidates manually
+  # order is important, the first will have a higher priority
+  candidates:
+    - 216.58.210.174:8555    # if you have static public IP-address
+    - stun:8555              # if you have dynamic public IP-address
+    - home.duckdns.org:8555  # if you have domain
+
+  # add custom STUN and TURN servers
+  # use `ice_servers: []` for remove defaults and leave empty
+  ice_servers:
+    - urls: [ stun:stun1.l.google.com:19302 ]
+    - urls: [ turn:123.123.123.123:3478 ]
+      username: your_user
+      credential: your_pass
+
+  # optional filter list for auto discovery logic
+  # some settings only make sense if you don't specify a fixed UDP port  
+  filters:
+    # list of host candidates from auto discovery to be sent
+    # including candidates from the `listen` option
+    # use `candidates: []` to remove all auto discovery candidates
+    candidates: [ 192.168.1.123 ]
+
+    # list of network types to be used for connection
+    # including candidates from the `listen` option
+    networks: [ udp4, udp6, tcp4, tcp6 ]
+
+    # list of interfaces to be used for connection
+    # not related to the `listen` option
+    interfaces: [ eno1 ]
+
+    # list of host IP-addresses to be used for connection
+    # not related to the `listen` option
+    ips: [ 192.168.1.123 ]
+
+    # range for random UDP ports [min, max] to be used for connection
+    # not related to the `listen` option
+    udp_ports: [ 50000, 50100 ]
+```
+
+By default go2rtc uses **fixed TCP** port and multiple **random UDP** ports for each WebRTC connection - `listen: ":8555/tcp"`.
+
+You can set **fixed TCP** and **fixed UDP** port for all connections - `listen: ":8555"`. This may has lower performance, but it's your choice. 
+
+Don't know why, but you can disable TCP port and leave only random UDP ports - `listen: ""`.
+
+## Config filters
+
+Filters allow you to exclude unnecessary candidates. Extra candidates don't make your connection worse or better. But the wrong filter settings can break everything. Skip this setting if you don't understand it.
+
+For example, go2rtc is installed on the host system. And there are unnecessary interfaces. You can keep only the relevant via `interfaces` or `ips` options. You can also exclude IPv6 candidates if your server supports them but your home network does not.
+
+```yaml
+webrtc:
+  listen: ":8555/tcp"         # use fixed TCP port and random UDP ports
+  filters:
+    ips: [ 192.168.1.2 ]      # IP-address of your server
+    networks: [ udp4, tcp4 ]  # skip IPv6, if it's not supported for you
+```
+
+For example, go2rtc inside closed docker container (ex. [Frigate](https://frigate.video/)). You shouldn't filter docker interfaces, otherwise go2rtc will not be able to connect anywhere. But you can filter the docker candidates because no one can connect to them.
+
+```yaml
+webrtc:
+  listen: ":8555"                   # use fixed TCP and UDP ports
+  candidates: [ 192.168.1.2:8555 ]  # add manual host candidate (use docker port forwarding)
+  filters:
+    candidates: []                  # skip all internal docker candidates
+```
