Live H264 stream from RTSP camera to your browser
a new, completely rewritten version!
It this demo we're streaming live video from an RTSP camera to your HTML5 browser.
Video is streamed as H264 encapsulated in MP4. No transcoding takes place in the stream-to-browser pipeline. No browser-side flash or pure-javascript decoders required.
Video is decoded and presented in the browser using the W3 Media Source Extensions that is well supported by all major browsers by now.
Only H264 is supported - browser MSE's do not support H246 yet (and neither does libValkka).
How does it work?
Roughly like this:
server-side nginx
ws_serve_new.py <-- websocket <---------------+-* <----+ <---- web browser
| |
ws_client_new.html <-----+ |
| |
+--------------------------+
(requests websocket)
Starts nginx
Uses libValkka JavaScript
W3 MediaSource Extension
The web-browser client uses the W3 Media Source Extensions to push the payload into browsers video decoding infrastructure.
Requirements
- Install libValkka as instructed here
- Install nginx with
sudo apt-get install nginx - Install python websocket module with
pip3 install --user websockets - Prepare nginx user rights:
sudo addgroup nginx
sudo chgrp nginx /var/lib/nginx
sudo adduser $USER nginx
sudo chmod g+r+w+x /var/lib/nginx
- You need to do logout/login (so that group change takes effect)
- Test if your nginx works correctly
nginx -p $PWD -c ./nginx.conf -g 'error_log error.log warn;'
- Setup your camera so that it sends H264 only.
Usage
1. Start the program with
killall -9 nginx; python3 ws_serve_new.py rtsp://user:password@ip-address
An X-window is opened that shows you the live video stream.
2. Open your browser
Your low-latency live video is now available at http://localhost:8089
Now what?
- Please tell me in the issues if this worked for you or not and what camera & other setup you are using
- ..i.e. don't just report the bugs, but also successes! :)
