+# Modules
+
+go2rtc tries to name formats, protocols and codecs the same way they are named in FFmpeg.
+Some formats and protocols go2rtc supports exclusively. They have no equivalent in FFmpeg.
+
+- The [`echo`], [`expr`], [`hass`] and [`onvif`] modules receive a link to a stream. They don't know the protocol in advance.
+- The [`exec`] and [`ffmpeg`] modules support many formats. They are identical to the [`http`] module.
+- The [`api`], [`app`], [`debug`], [`ngrok`], [`pinggy`], [`srtp`], [`streams`] are supporting modules.
+
+**Modules** implement communication APIs: authorization, encryption, command set, structure of media packets.
+
+**Formats** describe the structure of the data being transmitted.
+
+**Protocols** implement transport for data transmission.

-## Exit codes
+# HTTP API
 
-- https://tldp.org/LDP/abs/html/exitcodes.html
+The HTTP API is the main part for interacting with the application. Default address: `http://localhost:1984/`.
-- https://komodor.com/learn/exit-codes-in-containers-and-kubernetes-the-complete-guide/
+
+The HTTP API is described in [OpenAPI](../../website/api/openapi.yaml) format. It can be explored in [interactive viewer](https://go2rtc.org/api/). WebSocket API described [here](ws/README.md).
+
+The project's static HTML and JS files are located in the [www](../../www/README.md) folder. An external developer can use them as a basis for integrating go2rtc into their project or for developing a custom web interface for go2rtc.
+
+The contents of `www` folder are built into go2rtc when building, but you can use configuration to specify an external folder as the source of static files.
+
+## Configuration
+
+**Important!** go2rtc passes requests from localhost and Unix sockets without HTTP authorization, even if you have it configured. It is your responsibility to set up secure external access to the API. If not properly configured, an attacker can gain access to your cameras and even your server.
+
+- you can disable HTTP API with `listen: ""` and use, for example, only RTSP client/server protocol
+- you can enable HTTP API only on localhost with `listen: "127.0.0.1:1984"` setting
+- you can change the API `base_path` and host go2rtc on your main app webserver suburl
+- all files from `static_dir` hosted on root path: `/`
+- you can use raw TLS cert/key content or path to files
+
+```yaml
+api:
+  listen: ":1984"    # default ":1984", HTTP API port ("" - disabled)
+  username: "admin"  # default "", Basic auth for WebUI
+  password: "pass"   # default "", Basic auth for WebUI
+  local_auth: true   # default false, Enable auth check for localhost requests
+  base_path: "/rtc"  # default "", API prefix for serving on suburl (/api => /rtc/api)
+  static_dir: "www"  # default "", folder for static files (custom web interface)
+  origin: "*"        # default "", allow CORS requests (only * supported)
+  tls_listen: ":443" # default "", enable HTTPS server
+  tls_cert: |        # default "", PEM-encoded fullchain certificate for HTTPS
+    -----BEGIN CERTIFICATE-----
+    ...
+    -----END CERTIFICATE-----
+  tls_key: |         # default "", PEM-encoded private key for HTTPS
+    -----BEGIN PRIVATE KEY-----
+    ...
+    -----END PRIVATE KEY-----
+  unix_listen: "/tmp/go2rtc.sock"  # default "", unix socket listener for API
+```
+
+**PS:**
+
+- MJPEG over WebSocket plays better than native MJPEG because Chrome [bug](https://bugs.chromium.org/p/chromium/issues/detail?id=527446)
+- MP4 over WebSocket was created only for Apple iOS because it doesn't support file streaming

+# App
+
+The application module is responsible for reading configuration files, running other modules and setting up [logs](#log).
+
+The configuration can be edited through the application's WebUI with code highlighting, syntax and specification checking.
+
+- By default, go2rtc will search for the `go2rtc.yaml` config file in the current working directory
+- go2rtc supports multiple config files:
+  - `go2rtc -c config1.yaml -c config2.yaml -c config3.yaml`
+- go2rtc supports inline config in multiple formats from the command line:
+  - **YAML**: `go2rtc -c '{log: {format: text}}'`
+  - **JSON**: `go2rtc -c '{"log":{"format":"text"}}'`
+  - **key=value**: `go2rtc -c log.format=text`
+- Each subsequent config will overwrite the previous one (but only for defined params)
+
+```
+go2rtc -config "{log: {format: text}}" -config /config/go2rtc.yaml -config "{rtsp: {listen: ''}}" -config /usr/local/go2rtc/go2rtc.yaml
+```
+
+or a simpler 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 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/) support autocomplete and syntax validation.
+
+```yaml
+# yaml-language-server: $schema=https://raw.githubusercontent.com/AlexxIT/go2rtc/master/www/schema.json
+```
+
+or from a running go2rtc:
+
+```yaml
+# yaml-language-server: $schema=http://localhost:1984/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
+
+```yaml
+api:
+  listen: ":1984"  # default public port for WebUI and HTTP API
+
+ffmpeg:
+  bin: "ffmpeg"    # default binary path for FFmpeg
+
+log:
+  level: "info"    # default log level
+  output: "stdout"
+  time: "UNIXMS"
+
+rtsp:
+  listen: ":8554"  # default public port for RTSP server
+  default_query: "video&audio"
+
+srtp:
+  listen: ":8443"  # default public port for SRTP server (used for HomeKit)
+
+webrtc:
+  listen: ":8555"  # default public port for WebRTC server (TCP and UDP)
+  ice_servers:
+    - urls: [ "stun:stun.cloudflare.com:3478", "stun:stun.l.google.com:19302" ]
+```
+
+## Log
+
+You can set different log levels for different modules.
+
+```yaml
+log:
+  format: ""        # empty (default, autodetect color support), color, json, text 
+  level: "info"     # disabled, trace, debug, info (default), warn, error
+  output: "stdout"  # empty (only to memory), stderr, stdout (default)
+  time: "UNIXMS"    # empty (disable timestamp), UNIXMS (default), UNIXMICRO, UNIXNANO
+  
+  api: trace   # module name: log level
+```
+
+Modules: `api`, `streams`, `rtsp`, `webrtc`, `mp4`, `hls`, `mjpeg`, `hass`, `homekit`, `onvif`, `rtmp`, `webtorrent`, `wyoming`, `echo`, `exec`, `expr`, `ffmpeg`, `wyze`, `xiaomi`.

+# Echo
+
+Some sources may have a dynamic link. And you will need to get it using a Bash or Python script. Your script should echo a link to the source. RTSP, FFmpeg or any of the supported sources.
+
+**Docker** and **Home Assistant add-on** users have preinstalled `python3`, `curl`, `jq`.
+
+## Configuration
+
+```yaml
+streams:
+  apple_hls: echo:python3 hls.py https://developer.apple.com/streaming/examples/basic-stream-osx-ios5.html
+```
+
+## Install python libraries
+
+**Docker** and **Hass Add-on** users have preinstalled `python3` without any additional libraries, like [requests](https://requests.readthedocs.io/) or others. If you need some additional libraries - you need to install them to folder with your script:
+
+1. Install [SSH & Web Terminal](https://github.com/hassio-addons/addon-ssh)
+2. Goto Add-on Web UI
+3. Install library: `pip install requests -t /config/echo`
+4. Add your script to `/config/echo/myscript.py`
+5. Use your script as source `echo:python3 /config/echo/myscript.py`
+
+## Example: Apple HLS
+
+```yaml
+streams:
+  apple_hls: echo:python3 hls.py https://developer.apple.com/streaming/examples/basic-stream-osx-ios5.html
+```
+
+**hls.py**

+# Exec
+
+Exec source can run any external application and expect data from it. Two transports are supported - **pipe** ([`new in v1.5.0`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.5.0)) and **RTSP**.
+
+If you want to use **RTSP** transport, the command must contain the `{output}` argument in any place. On launch, it will be replaced by the local address of the RTSP server.
+
+**pipe** reads data from app stdout in different formats: **MJPEG**, **H.264/H.265 bitstream**, **MPEG-TS**. Also pipe can write data to app stdin in two formats: **PCMA** and **PCM/48000**.
+
+The source can be used with:
+
+- [FFmpeg](https://ffmpeg.org/) - go2rtc ffmpeg source is just a shortcut to exec source
+- [FFplay](https://ffmpeg.org/ffplay.html) - play audio on your server
+- [GStreamer](https://gstreamer.freedesktop.org/)
+- [Raspberry Pi Cameras](https://www.raspberrypi.com/documentation/computers/camera_software.html)
+- any of your own software
+
+## Configuration
+
+Pipe commands support parameters (format: `exec:{command}#{param1}#{param2}`):
+
+- `killsignal` - signal which will be sent to stop the process (numeric form)
+- `killtimeout` - time in seconds for forced termination with sigkill
+- `backchannel` - enable backchannel for two-way audio
+- `starttimeout` - time in seconds for waiting first byte from RTSP
+
+```yaml
+streams:
+  stream: exec:ffmpeg -re -i /media/BigBuckBunny.mp4 -c copy -rtsp_transport tcp -f rtsp {output}
+  picam_h264: exec:libcamera-vid -t 0 --inline -o -
+  picam_mjpeg: exec:libcamera-vid -t 0 --codec mjpeg -o -
+  pi5cam_h264: exec:libcamera-vid -t 0 --libav-format h264 -o -
+  canon: exec:gphoto2 --capture-movie --stdout#killsignal=2#killtimeout=5
+  play_pcma: exec:ffplay -fflags nobuffer -f alaw -ar 8000 -i -#backchannel=1
+  play_pcm48k: exec:ffplay -fflags nobuffer -f s16be -ar 48000 -i -#backchannel=1
+```
+
+## Backchannel
+
+- You can check audio card names in the **Go2rtc > WebUI > Add**
+- You can specify multiple backchannel lines with different codecs
+
+```yaml
+sources:
+  two_way_audio_win:
+    - exec:ffmpeg -hide_banner -f dshow -i "audio=Microphone (High Definition Audio Device)" -c pcm_s16le -ar 16000 -ac 1 -f wav -

+# Expr
+
+[`new in v1.8.2`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.8.2)
+
+[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';

+
+    'rtsp://' + host + '/cam/realmonitor?channel=1&subtype=0&unicast=true&proto=Onvif'
+```
+
+**dom.ru**
+
+You can get credentials from https://github.com/ad/domru

+You can get any stream, file or device via FFmpeg and push it to go2rtc. The app will automatically start FFmpeg with the proper arguments when someone starts watching the stream.
 
-- `7.11` - master clock, is the time from start of the stream/video
+- FFmpeg preinstalled for **Docker** and **Home Assistant add-on** users
-- `A-V` - av_diff, difference between audio and video timestamps
+- **Home Assistant add-on** users can target files from [/media](https://www.home-assistant.io/more-info/local-media/setup-media/) folder
-- `fd` - frames dropped
-- `aq` - audio queue (0 - no delay)
-- `vq` - video queue (0 - no delay)
-- `sq` - subtitle queue
-- `f` - timestamp error correction rate (Not 100% sure)

+But you can override them via YAML config. You can also add your own formats to the config and use them with source params.

-## Devices Linux 
+- You can use go2rtc stream name as ffmpeg input (ex. `ffmpeg:camera1#video=h264`)
+- You can use `video` and `audio` params multiple times (ex. `#video=copy#audio=copy#audio=pcmu`)
+- You can use `rotate` param with `90`, `180`, `270` or `-90` values, important with transcoding (ex. `#video=h264#rotate=90`)
+- You can use `width` and/or `height` params, important with transcoding (ex. `#video=h264#width=1280`)
+- You can use `drawtext` to add a timestamp (ex. `drawtext=x=2:y=2:fontsize=12:fontcolor=white:box=1:boxcolor=black`)
+    - This will greatly increase the CPU of the server, even with hardware acceleration
+- You can use `timeout` param to set RTSP input timeout in seconds (ex. `#timeout=10`)
+- You can use `raw` param for any additional FFmpeg arguments (ex. `#raw=-vf transpose=1`)
+- You can use `input` param to override default input template (ex. `#input=rtsp/udp` will change RTSP transport from TCP to UDP+TCP)
+    - You can use raw input value (ex. `#input=-timeout {timeout} -i {input}`)
+    - You can add your own input templates

+# Hardware
+
+You **DON'T** need hardware acceleration if:
+
+- you're not using the [FFmpeg source](../README.md)
+- you're using only `#video=copy` for the FFmpeg source
+- you're using only `#audio=...` (any audio) transcoding for the FFmpeg source
+
+You **NEED** hardware acceleration if you're using `#video=h264`, `#video=h265`, `#video=mjpeg` (video) transcoding.
+
+## Important
+
+- Acceleration is disabled by default because it can be unstable (this may change in the future)
+- go2rtc can automatically detect supported hardware acceleration if enabled
+- go2rtc will enable hardware decoding only if hardware encoding is supported
+- go2rtc will use the same GPU for decoder and encoder
+- Intel and AMD will switch to a software decoder if the input codec isn't supported by the hardware decoder
+- NVIDIA will fail if the input codec isn't supported by the hardware decoder
+- Raspberry Pi always uses a 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) supports hardware acceleration for Intel iGPU (CPU with graphics) and Raspberry Pi.
+- Hardware (Debian 12) supports Intel iGPU, AMD GPU, NVIDIA GPU.
+
+## Intel iGPU
+
+**Supported on:** Windows binary, Linux binary, Docker, Hass Addon.
+
+If you have an Intel Sandy Bridge (2011) CPU with graphics, you already have hardware decoding/encoding support for `AVC/H.264`.
+
+If you have an Intel Skylake (2015) CPU with graphics, you already have hardware decoding/encoding support 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 a recent OS and Linux kernel. For example, on my **Debian 10 (kernel 4.19)** it did not work, but after updating to **Debian 11 (kernel 5.10)** everything was fine.
+- If you run into trouble, check that you have the `/dev/dri/` folder on your host.
+
+Docker users should add the `--privileged` option to the container for access to the 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 to test this!!!*
+
+**Supported on:** Linux binary, Docker, Hass Addon.
+
+Docker users should install: `alexxit/go2rtc:master-hardware`. Docker users should add the `--privileged` option to the container for access to the 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 extremely slow, even with hardware acceleration. Also, it may fail when transcoding a 2K+ stream.
+
+## Raspberry Pi 4
+
+*I don't have the hardware to test this!!!*
+
+**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 the M1 CPU is better than any Intel iGPU and comparable to an NVIDIA RTX 2070.
+
+**PS.** Supported via [videotoolbox](https://trac.ffmpeg.org/wiki/HWAccelIntro#VideoToolbox) engine.
+
+## Rockchip
+
+- It's important to use a custom FFmpeg build with Rockchip support from [@nyanmisaka](https://github.com/nyanmisaka/ffmpeg-rockchip)
+  - Static binaries from [@MarcA711](https://github.com/MarcA711/Rockchip-FFmpeg-Builds/releases/)
+- It's important to have Linux kernel 5.10 or 6.1
+
+**Tested**
+
+- [Orange Pi 3B](https://www.armbian.com/orangepi3b/) with Armbian 6.1, supports transcoding H.264, H.265, MJPEG

+[`new in v1.8.3`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.8.3)
+
+Support streaming from [GoPro](https://gopro.com/) cameras, connected via USB or Wi-Fi to Linux, Mac, Windows.
+
+Supported models: HERO9, HERO10, HERO11, HERO12.  
+Supported OS: Linux, Mac, Windows, [HassOS](https://www.home-assistant.io/installation/)
+
+Other camera models have different APIs. I will try to add them in future versions.
+
+## Configuration
+
+- 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 the firewall
+
+1. Discover camera address: WebUI > Add > GoPro
+2. Add camera to config
+
+```yaml
+streams:
+  hero12: gopro://172.20.100.51
+```

+### WebRTC Cameras
+
+[`new in v1.6.0`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.6.0)
+
+Any cameras in WebRTC format are supported. But at the moment Home Assistant only supports some [Nest](https://www.home-assistant.io/integrations/nest/) cameras in this format.
+
+**Important.** The Nest API only allows you to get a link to a stream for 5 minutes.
+Do not use this with Frigate! If the stream expires, Frigate will consume all available RAM on your machine within seconds.
+It's recommended to use [Nest source](../nest/README.md) - it supports extending the stream.
+
+```yaml
+streams:
+  # link to Home Assistant Supervised
+  hass-webrtc1: hass://supervisor?entity_id=camera.nest_doorbell
+  # link to external Home Assistant with Long-Lived Access Tokens
+  hass-webrtc2: hass://192.168.1.123:8123?entity_id=camera.nest_doorbell&token=eyXYZ...
+```
+
+### RTSP Cameras
+
+By default, the Home Assistant API does not allow you to get a dynamic RTSP link to a camera stream. [This method](https://github.com/felipecrs/hass-expose-camera-stream-source#importing-cameras-from-home-assistant-to-go2rtc-or-frigate) can work around it.

+
+[HLS](https://en.wikipedia.org/wiki/HTTP_Live_Streaming) is the worst technology for real-time streaming. 
+It can only be useful on devices that do not support more modern technology, like [WebRTC](../webrtc/README.md), [MP4](../mp4/README.md).
+
+The go2rtc implementation differs from the standards and may not work with all players.
+
+API examples:
+
+- HLS/TS stream: `http://192.168.1.123:1984/api/stream.m3u8?src=camera1` (H264)
+- HLS/fMP4 stream: `http://192.168.1.123:1984/api/stream.m3u8?src=camera1&mp4` (H264, H265, AAC)
+
+Read more about [codecs filters](../../README.md#codecs-filters).

+# Apple HomeKit
+
+This module supports both client and server for the [Apple HomeKit](https://www.apple.com/home-app/accessories/) protocol.
+
+## HomeKit Client
+
+**Important:**
+
+- You can use HomeKit Cameras **without Apple devices** (iPhone, iPad, etc.), it's just a yet another protocol
+- HomeKit device can be paired with only one ecosystem. So, if you have paired it to an iPhone (Apple Home), you can't pair it with Home Assistant or go2rtc. Or if you have paired it to go2rtc, you can't pair it with an iPhone
+- HomeKit device should be on the same network with working [mDNS](https://en.wikipedia.org/wiki/Multicast_DNS) between the device and go2rtc
+
+go2rtc supports importing paired HomeKit devices from [Home Assistant](../hass/README.md). 
+So you can use HomeKit camera with Home Assistant and go2rtc simultaneously. 
+If you are using Home Assistant, I recommend pairing devices with it; it will give you more options.
+
+You can pair device with go2rtc on the HomeKit page. If you can't see your devices, reload the page. 
+Also, try rebooting your HomeKit device (power off). If you still can't see it, you have a problem with mDNS.
+
+If you see a device but it does not have a pairing button, it is paired to some ecosystem (Apple Home, Home Assistant, HomeBridge, etc.). You need to delete the device from that ecosystem, and it will be available for pairing. If you cannot unpair the device, you will have to reset it.
+
+**Important:**
+
+- HomeKit audio uses very non-standard **AAC-ELD** codec with very non-standard params and specification violations
+- Audio can't be played in `VLC` and probably any other player
+- Audio should be transcoded for use with MSE, WebRTC, etc.
+
+### Client Configuration
+
+Recommended settings for using HomeKit Camera with WebRTC, MSE, MP4, RTSP:
+
+```yaml
+streams:
+  aqara_g3:
+    - hass:Camera-Hub-G3-AB12
+    - ffmpeg:aqara_g3#audio=aac#audio=opus
+```
+
+RTSP link with "normal" audio for any player: `rtsp://192.168.1.123:8554/aqara_g3?video&audio=aac`
+
+**This source is in active development!** Tested only with [Aqara Camera Hub G3](https://www.aqara.com/eu/product/camera-hub-g3) (both EU and CN versions).
+
+## HomeKit Server
+
+[`new in v1.7.0`](https://github.com/AlexxIT/go2rtc/releases/tag/v1.7.0)
+
+HomeKit module can work in two modes:
+
+- export any H264 camera to Apple HomeKit
+- transparent proxy any Apple HomeKit camera (Aqara, Eve, Eufy, etc.) back to Apple HomeKit, so you will have all camera features in Apple Home and also will have RTSP/WebRTC/MP4/etc. from your HomeKit camera
+
+**Important**
+
+- HomeKit cameras support only H264 video and OPUS audio
+
+### Server Configuration
+
+**Minimal config**
+
+```yaml
+streams:
+  dahua1: rtsp://admin:password@192.168.1.123/cam/realmonitor?channel=1&subtype=0
+homekit:
+  dahua1:  # same stream ID from streams list, default PIN - 19550224
+```
+
+**Full config**
+
+```yaml
+streams:
+  dahua1:
+    - rtsp://admin:password@192.168.1.123/cam/realmonitor?channel=1&subtype=0
+    - ffmpeg:dahua1#video=h264#hardware  # if your camera doesn't support H264, important for HomeKit
+    - ffmpeg:dahua1#audio=opus           # only OPUS audio supported by HomeKit
+
+homekit:
+  dahua1:                   # same stream ID from streams list
+    pin: 12345678           # custom PIN, default: 19550224
+    name: Dahua camera      # custom camera name, default: generated from stream ID
+    device_id: dahua1       # custom ID, default: generated from stream ID
+    device_private: dahua1  # custom key, default: generated from stream ID
+```
+
+**Proxy HomeKit camera**
+
+- Video stream from HomeKit camera to Apple device (iPhone, Apple TV) will be transmitted directly
+- Video stream from HomeKit camera to RTSP/WebRTC/MP4/etc. will be transmitted via go2rtc
+
+```yaml
+streams:
+  aqara1:
+    - homekit://...
+    - ffmpeg:aqara1#audio=aac#audio=opus  # optional audio transcoding
+
+homekit:
+  aqara1:  # same stream ID from streams list
+```
