+You can get any stream as RTMP-stream: `rtmp://192.168.1.123/{stream_name}`. Only H264/AAC codecs supported right now.
+
+[Incoming stream](#incoming-sources) in RTMP-format tested only with [OBS Studio](https://obsproject.com/) and Dahua camera. Different FFmpeg versions has differnt problems with this format.

+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
+

+- stream technology autoselection `mode=webrtc,webrtc/tcp,mse,hls,mp4,mjpeg`

+- `media=video+audio+microphone` - two way audio from camera
+- `media=camera+microphone` - stream from browser
+- `media=display+speaker` - stream from desktop

+- 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:

+    - 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
+

+1. Video and Audio better than just Video
+2. H265 better than H264
