+
+## HTTP API
+
+Interactive [OpenAPI](https://alexxit.github.io/go2rtc/api/).
+
+`www/stream.html` - universal viewer with support params in URL:
+
+- multiple streams on page `src=camera1&src=camera2...`
+- stream technology autoselection `mode=webrtc,webrtc/tcp,mse,hls,mp4,mjpeg`
+- stream technology comparison `src=camera1&mode=webrtc&mode=mse&mode=mp4`
+- player width setting in pixels `width=320px` or percents `width=50%`
+
+`www/webrtc.html` - WebRTC viewer with support two way audio and params in URL:
+
+- `media=video+audio` - simple viewer
+- `media=video+audio+microphone` - two way audio from camera
+- `media=camera+microphone` - stream from browser
+- `media=display+speaker` - stream from desktop
+
+## JavaScript API
+
+- You can write your viewer from the scratch
+- You can extend the built-in viewer - `www/video-rtc.js`
+- Check example - `www/video-stream.js`
+- Check example - https://github.com/AlexxIT/WebRTC
+
+`video-rtc.js` features:
+
+- support technologies:
+    - WebRTC over UDP or TCP
+    - MSE or HLS or MP4 or MJPEG over WebSocket
+- automatic selection best technology according on:
+    - codecs inside your stream
+    - current browser capabilities
+    - current network configuration
+- automatic stop stream while browser or page not active
+- automatic stop stream while player not inside page viewport
+- automatic reconnection
+
+Technology selection based on priorities:
+
+1. Video and Audio better than just Video
+2. H265 better than H264
+3. WebRTC better than MSE, than HLS, than MJPEG
+
+## WebSocket API
+
+Endpoint: `/api/ws`
+
+Query parameters:
+
+- `src` (required) - Stream name

+- 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
+
+There is support for loading external variables into the config. First, they will be attempted to be loaded from [credential files](https://systemd.io/CREDENTIALS). If `CREDENTIALS_DIRECTORY` is not set, then the key will be loaded from an environment variable. If no environment variable is set, then the string will be left as-is.
+
+```yaml
+streams:
+  camera1: rtsp://rtsp:${CAMERA_PASSWORD}@192.168.1.123/av_stream/ch0
+
+rtsp:
+  username: ${RTSP_USER:admin}   # "admin" if "RTSP_USER" not set
+  password: ${RTSP_PASS:secret}  # "secret" if "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
+```
+
+## Defaults
+
+- Default values may change in updates
+- FFmpeg module has many presets, they are not listed here because they may also change in updates

+# Expr
+
+[Expr](https://github.com/antonmedv/expr) - expression language and expression evaluation for Go.
+
+- [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:
+  - `fetch` - JS-like HTTP requests
+  - `match` - JS-like RegExp queries
+
+## Examples
+

+        ? "rtsp://"+host+"/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif" : ""
+```
+
+**dom.ru**
+
+You can get credentials via:
+
+- https://github.com/alexmorbo/domru (file `/share/domru/accounts`)

+# Hardware
+
+You **DON'T** need hardware acceleration if:
+
+- you not using [FFmpeg source](https://github.com/AlexxIT/go2rtc#source-ffmpeg)
+- you using only `#video=copy` for FFmpeg source
+- you using only `#audio=...` (any audio) transcoding for FFmpeg source
+
+You **NEED** hardware acceleration if you using `#video=h264`, `#video=h265`, `#video=mjpeg` (video) transcoding.
+
+## Important
+
+- Acceleration is disabled by default because it can be unstable (it can be changed in future)
+- go2rtc can automatically detect supported hardware acceleration if enabled
+- go2rtc will enable hardware decoding only if hardware encoding supported
+- go2rtc will use the same GPU for decoder and encoder
+- Intel and AMD will switch to software decoder if input codec is not supported with hardware decoder
+- NVidia will fail if input codec is not supported with hardware decoder
+- Raspberry always uses software decoder

+
+## Docker and Hass Addon
+
+There are two versions of the Docker container and Hass Add-on:
+
+- Latest (alpine) support hardware acceleration for Intel iGPU (CPU with Graphics) and Raspberry.
+- Hardware (debian 12) support Intel iGPU, AMD GPU, NVidia GPU.
+
+## Intel iGPU
+
+**Supported on:** Windows binary, Linux binary, Docker, Hass Addon.
+
+If you have Intel CPU Sandy Bridge (2011) with Graphics, you already have support hardware decoding/encoding for `AVC/H.264`.
+
+If you have Intel CPU Skylake (2015) with Graphics, you already have support hardware decoding/encoding for `AVC/H.264`, `HEVC/H.265` and `MJPEG`.
+
+Read more [here](https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video#Hardware_decoding_and_encoding) and [here](https://en.wikipedia.org/wiki/Intel_Graphics_Technology#Capabilities_(GPU_video_acceleration)).
+
+Linux and Docker:
+
+- It may be important to have the latest version of the OS with the latest version of the Linux kernel. For example, on my **Debian 10 (kernel 4.19)** it did not work, but after update to **Debian 11 (kernel 5.10)** all was fine.
+- In case of troube check you have `/dev/dri/` folder on your host.
+
+Docker users should add `--privileged` option to container for access to Hardware.
+
+**PS.** Supported via [VAAPI](https://trac.ffmpeg.org/wiki/Hardware/VAAPI) engine on Linux and [DXVA2+QSV](https://trac.ffmpeg.org/wiki/Hardware/QuickSync) engine on Windows.
+
+## AMD GPU
+
+*I don't have the hardware for test support!!!*
+
+**Supported on:** Linux binary, Docker, Hass Addon.
+
+Docker users should install: `alexxit/go2rtc:master-hardware`. Docker users should add `--privileged` option to container for access to Hardware.
+
+Hass Addon users should install **go2rtc master hardware** version.
+
+**PS.** Supported via [VAAPI](https://trac.ffmpeg.org/wiki/Hardware/VAAPI) engine.
+
+## NVidia GPU
+
+**Supported on:** Windows binary, Linux binary, Docker.
+
+Docker users should install: `alexxit/go2rtc:master-hardware`.
+
+Read more [here](https://docs.frigate.video/configuration/hardware_acceleration) and [here](https://jellyfin.org/docs/general/administration/hardware-acceleration/#nvidia-hardware-acceleration-on-docker-linux).
+
+**PS.** Supported via [CUDA](https://trac.ffmpeg.org/wiki/HWAccelIntro#CUDANVENCNVDEC) engine.
+
+## Raspberry Pi 3
+
+**Supported on:** Linux binary, Docker, Hass Addon.
+
+I don't recommend using transcoding on the Raspberry Pi 3. It's extreamly slow, even with hardware acceleration. Also it may fail when transcoding 2K+ stream.
+
+## Raspberry Pi 4
+
+*I don't have the hardware for test support!!!*
+
+**Supported on:** Linux binary, Docker, Hass Addon.
+
+**PS.** Supported via [v4l2m2m](https://lalitm.com/hw-encoding-raspi/) engine.
+
+## macOS
+
+In my tests, transcoding is faster on the M1 CPU than on the M1 GPU. Transcoding time on M1 CPU better than any Intel iGPU and comparable to NVidia RTX 2070.
+
+**PS.** Supported via [videotoolbox](https://trac.ffmpeg.org/wiki/HWAccelIntro#VideoToolbox) engine.
+
+## Rockchip
+
+- Important to use custom FFmpeg with Rockchip support from [@nyanmisaka](https://github.com/nyanmisaka/ffmpeg-rockchip)
+  - Static binaries from [@MarcA711](https://github.com/MarcA711/Rockchip-FFmpeg-Builds/releases/)
+- Important to have Linux kernel 5.10 or 6.1
+
+**Tested**
+
+- [Orange Pi 3B](https://www.armbian.com/orangepi3b/) with Armbian 6.1, support transcoding H264, H265, MJPEG
