+# API
+
+Fill free to make any API design proposals.
+
+## HTTP API
+
+Interactive [OpenAPI](https://go2rtc.org/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
+
+### WebRTC
+
+Request SDP:
+
+```json
+{"type":"webrtc/offer","value":"v=0\r\n..."}
+```
+
+Response SDP:
+
+```json
+{"type":"webrtc/answer","value":"v=0\r\n..."}
+```
+
+Request/response candidate:
+
+- empty value also allowed and optional
+
+```json
+{"type":"webrtc/candidate","value":"candidate:3277516026 1 udp 2130706431 192.168.1.123 54321 typ host"}
+```
+
+### MSE

+```
+

+- 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

+# 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
+
+## Fetch examples
+
+Multiple fetch requests are executed within a single session. They share the same cookie.
+
+**HTTP GET**
+
+```js
+var r = fetch('https://example.org/products.json');
+```
+
+**HTTP POST JSON**
+
+```js
+var r = fetch('https://example.org/post', {
+    method: 'POST',
+    // Content-Type: application/json will be set automatically
+    json: {username: 'example'}
+});
+```
+
+**HTTP POST Form**
+
+```js
+var r = fetch('https://example.org/post', {
+    method: 'POST',
+    // Content-Type: application/x-www-form-urlencoded will be set automatically
+    data: {username: 'example', password: 'password'}
+});
+```
+
+## Script examples
+
+**Two way audio for Dahua VTO**
+
+```yaml
+streams:
+  dahua_vto: |
+    expr:
+    let host = 'admin:password@192.168.1.123';
+
+    var r = fetch('http://' + host + '/cgi-bin/configManager.cgi?action=setConfig&Encode[0].MainFormat[0].Audio.Compression=G.711A&Encode[0].MainFormat[0].Audio.Frequency=8000');
+
+    'rtsp://' + host + '/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif'
+```
+
+**dom.ru**
+
+You can get credentials from https://github.com/ad/domru
+
+```yaml
+streams:
+  dom_ru: |
+    expr:
+    let camera   = '***';
+    let token    = '***';
+    let operator = '***';
+
+    fetch('https://myhome.proptech.ru/rest/v1/forpost/cameras/' + camera + '/video', {
+      headers: {
+        'Authorization': 'Bearer ' + token,
+        'User-Agent': 'Google sdkgphone64x8664 | Android 14 | erth | 8.26.0 (82600010) | 0 | 0 | 0',
+        'Operator': operator
+      }
+    }).json().data.URL
+```
+
+**dom.ufanet.ru**
+
+```yaml
+streams:
+  ufanet_ru: |
+    expr:
+    let username = '***';
+    let password = '***';
+    let cameraid = '***';
+
+    let r1 = fetch('https://ucams.ufanet.ru/api/internal/login/', {
+      method: 'POST',
+      data: {username: username, password: password}
+    });
+    let r2 = fetch('https://ucams.ufanet.ru/api/v0/cameras/this/?lang=ru', {
+      method: 'POST',
+      json: {'fields': ['token_l', 'server'], 'token_l_ttl': 3600, 'numbers': [cameraid]},
+    }).json().results[0];
+
+    'rtsp://' + r2.server.domain + '/' + r2.number + '?token=' + r2.token_l
+```
+
+**Parse HLS files from Apple**
+

+# 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
+
+```yaml
+streams:
+  # auto select hardware encoder
+  camera1_hw: ffmpeg:rtsp://rtsp:12345678@192.168.1.123/av_stream/ch0#video=h264#hardware
+  
+  # manual select hardware encoder (vaapi, cuda, v4l2m2m, dxva2, videotoolbox)
+  camera1_vaapi: ffmpeg:rtsp://rtsp:12345678@192.168.1.123/av_stream/ch0#video=h264#hardware=vaapi
+```
+
+## 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
