+[WebRTC Camera](https://github.com/AlexxIT/WebRTC) custom component can be used on any [Home Assistant installation](https://www.home-assistant.io/installation/), including [HassWP](https://github.com/AlexxIT/HassWP) on Windows. It can automatically download and use the latest version of go2rtc. Or it can connect to an existing version of go2rtc. Addon installation in this case is optional.
 
 ## Configuration
 
-Create file `go2rtc.yaml` next to the app.
+- by default go2rtc will search `go2rtc.yaml` in the current work dirrectory
+- `api` server will start on default **1984 port** (TCP)
+- `rtsp` server will start on default **8554 port** (TCP)
+- `webrtc` will use port **8555** (TCP/UDP) for connections
+- `ffmpeg` will use default transcoding options
 
-- by default, you need to config only your `streams` links
-- `api` server will start on default **1984 port**
-- `rtsp` server will start on default **8554 port**
-- `webrtc` will use random UDP port for each connection
-- `ffmpeg` will use default transcoding options (you may install it [manually](https://ffmpeg.org/))
+Configuration options and a complete list of settings can be found in [the wiki](https://github.com/AlexxIT/go2rtc/wiki/Configuration).

 #### Source: RTSP
 
-- Support **RTSP and RTSPS** links with multiple video and audio tracks
-- Support **2-way audio** ONLY for [ONVIF Profile T](https://www.onvif.org/specs/stream/ONVIF-Streaming-Spec.pdf) cameras (back channel connection)
-

 ```yaml
 streams:
   sonoff_camera: rtsp://rtsp:12345678@192.168.1.123/av_stream/ch0

-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.
-
-**Attention:** Dahua cameras has different capabilities for different RTSP links. For example, it has support multiple codecs for 2-way audio with `&proto=Onvif` in link and only one codec without it.

-**PS.** For disable bachannel just add `#backchannel=0` to end of RTSP link.
+**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)
+- **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

+```
+
+#### Source: WebTorrent
+
+This source can get a stream from another go2rtc via [WebTorrent](#module-webtorrent) protocol.
+
+```yaml
+streams:
+  webtorrent1: webtorrent:?share=huofssuxaty00izc&pwd=k3l2j9djeg8v8r7e
+```
+
+#### Incoming sources
+
+By default, go2rtc establishes a connection to the source when any client requests it. Go2rtc drops the connection to the source when it has no clients left.
+
+- Go2rtc also can accepts incoming sources in [RTSP](#source-rtsp), [HTTP](#source-http) and **WebRTC/WHIP** formats
+- Go2rtc won't stop such a source if it has no clients
+- You can push data only to existing stream (create stream with empty source in config)
+- You can push multiple incoming sources to same stream
+- You can push data to non empty stream, so it will have additional codecs inside
+
+**Examples**
+
+- RTSP with any codec
+  ```yaml
+  ffmpeg -re -i BigBuckBunny.mp4 -c copy -rtsp_transport tcp -f rtsp rtsp://localhost:8554/camera1
+  ```
+- HTTP-MJPEG with MJPEG codec
+  ```yaml
+  ffmpeg -re -i BigBuckBunny.mp4 -c mjpeg -f mpjpeg http://localhost:1984/api/stream.mjpeg?dst=camera1
+  ```
+- HTTP-FLV with H264, AAC codecs
+  ```yaml
+  ffmpeg -re -i BigBuckBunny.mp4 -c copy -f flv http://localhost:1984/api/stream.flv?dst=camera1
+  ```
+- MPEG-TS with H264 codec
+  ```yaml
+  ffmpeg -re -i BigBuckBunny.mp4 -c copy -f mpegts http://localhost:1984/api/stream.ts?dst=camera1
+  ```
+
+#### Incoming: Browser
+
+You can turn the browser of any PC or mobile into an IP-camera with support video and two way audio. Or even broadcast your PC screen:
+
+1. Create empty stream in the `go2rtc.yaml`
+2. Go to go2rtc WebUI
+3. Open `links` page for you stream
+4. Select `camera+microphone` or `display+speaker` option
+5. Open `webrtc` local page (your go2rtc **should work over HTTPS!**) or `share link` via [WebTorrent](#module-webtorrent) technology (work over HTTPS by default)
+
+#### Incoming: WebRTC/WHIP
+
+You can use **OBS Studio** or any other broadcast software with [WHIP](https://www.ietf.org/archive/id/draft-ietf-wish-whip-01.html) protocol support. This standard has not yet been approved. But you can download OBS Studio [dev version](https://github.com/obsproject/obs-studio/actions/runs/3969201209):

+
+API example:
+
+```
+POST http://localhost:1984/api/streams?dst=camera1&src=ffmpeg:http://example.com/song.mp3#audio=pcma#input=file
+```
+
+- you can stream: local files, web files, live streams or any format, supported by FFmpeg 
+- you should use [ffmpeg source](#source-ffmpeg) for transcoding audio to codec, that your camera supports
+- you can check camera codecs on the go2rtc WebUI info page when the stream is active
+- some cameras support only low quality `PCMA/8000` codec (ex. [Tapo](#source-tapo))
+- it is recommended to choose higher quality formats if your camera supports them (ex. `PCMA/48000` for some Dahua cameras)
+- if you play files over http-link, you need to add `#input=file` params for transcoding, so file will be transcoded and played in real time
+- if you play live streams, you should skip `#input` param, because it is already in real time
+- you can stop active playback by calling the API with the empty `src` parameter
+- you will see one active producer and one active consumer in go2rtc WebUI info page during streaming

-- you can omit the codec filters, so one first video and one first audio will be selected
-- you can set `?video=copy` or just `?video`, so only one first video without audio will be selected
-- you can set multiple video or audio, so all of them will be selected
-- you can enable external password protection for your RTSP streams

 ### Module: WebRTC
 
-WebRTC usually works without problems in the local network. But external access may require additional settings. It depends on what type of Internet do you have.
+In most cases [WebRTC](https://en.wikipedia.org/wiki/WebRTC) uses direct peer-to-peer connection from your browser to go2rtc and sends media data via UDP.
+It **can't pass** media data through your Nginx or Cloudflare or [Nabu Casa](https://www.nabucasa.com/) HTTP TCP connection!
+It can automatically detects your external IP via public [STUN](https://en.wikipedia.org/wiki/STUN) server.
+It can establish a external direct connection via [UDP hole punching](https://en.wikipedia.org/wiki/UDP_hole_punching) technology even if you not open your server to the World.
 
-- by default, WebRTC use two random UDP ports for each connection (video and audio)
-- you can enable one additional TCP port for all connections and use it for external access
+But about 10-20% of users may need to configure additional settings for external access if **mobile phone** or **go2rtc server** behing [Symmetric NAT](https://tomchen.github.io/symmetric-nat-test/).
+
+- by default, WebRTC uses both TCP and UDP on port 8555 for connections

+By default WebRTC support only `PCMA/8000` and `PCMU/8000`. But go2rtc can automatically resample PCMA and PCMU codec with with a different sample rate. Also go2rtc can transcode `PCM` codec to `PCMA/8000`, so WebRTC can play it:
+
+```
+PCM/xxx => PCMA/8000 => WebRTC
+PCMA/xxx => PCMA/8000 => WebRTC
+PCMU/xxx => PCMU/8000 => WebRTC

+
+- [Dahua](https://www.dahuasecurity.com/) - reference implementation streaming protocols, a lot of settings, high stream quality, multiple streaming clients
+- [EZVIZ](https://www.ezviz.com/) - awful RTSP protocol realisation, many bugs in SDP
+- [Hikvision](https://www.hikvision.com/) - a lot of proprietary streaming technologies
+- [Reolink](https://reolink.com/) - some models has awful unusable RTSP realisation and not best HTTP-FLV alternative (I recommend that you contact Reolink support for new firmware), few settings
+- [Sonoff](https://sonoff.tech/) - very low stream quality, no settings, not best protocol implementation
+- [TP-Link](https://www.tp-link.com/) - few streaming clients, packet loss?
+- Chinese cheap noname cameras, Wyze Cams, Xiaomi cameras with hacks (usual has `/live/ch00_1` in RTSP URL) - awful but usable RTSP protocol realisation, low stream quality, few settings, packet loss?

 ## FAQ
 
 **Q. What's the difference between go2rtc, WebRTC Camera and RTSPtoWebRTC?**
 
 **go2rtc** is a new version of the server-side [WebRTC Camera](https://github.com/AlexxIT/WebRTC) integration, completely rewritten from scratch, with a number of fixes and a huge number of new features. It is compatible with native Home Assistant [RTSPtoWebRTC](https://www.home-assistant.io/integrations/rtsp_to_webrtc/) integration. So you [can use](#module-hass) default lovelace Picture Entity or Picture Glance.
 
-**Q. Why go2rtc is an addon and not an integration?**
+**Q. Should I use go2rtc addon or WebRTC Camera integration?**
 
-Because **go2rtc** is more than just viewing your stream online with WebRTC. You can use it all the time for your various tasks. But every time the Hass is rebooted - all integrations are also rebooted. So your streams may be interrupted if you use them in additional tasks.
+**go2rtc** is more than just viewing your stream online with WebRTC/MSE/HLS/etc. You can use it all the time for your various tasks. But every time the Hass is rebooted - all integrations are also rebooted. So your streams may be interrupted if you use them in additional tasks.
 
-When **go2rtc** is released, the **WebRTC Camera** integration will be updated. And you can decide whether to use the integration or the addon.
+Basic users can use **WebRTC Camera** integration. Advanced users can use go2rtc addon or Frigate 12+ addon.
 
 **Q. Which RTSP link should I use inside Hass?**
 
 You can use direct link to your cameras there (as you always do). **go2rtc** support zero-config feature. You may leave `streams` config section empty. And your streams will be created on the fly on first start from Hass. And your cameras will have multiple connections. Some from Hass directly and one from **go2rtc**.
 
-Also you can specify your streams in **go2rtc** [config file](#configuration) and use RTSP links to this addon. With additional features: multi-source [codecs negotiation](#codecs-negotiation) or FFmpeg [transcoding](#source-ffmpeg) for unsupported codecs. Or use them as source for Frigate. And your cameras will have one connection from **go2rtc**. And **go2rtc** will have multiple connection - some from Hass via RTSP protocol, some from your browser via WebRTC protocol.
