Enhancement request - MPEG-TS output via UDP for mediamtx #199

Open MittaAxt opened 1 year ago

MittaAxt commented 1 year ago

Hi

I would like to know if it would be possible to add UDP MPEG-TS output for the video/audio stream, which could be sent via TCP already. I'm looking to reduce the overall load on the pi, by trying to get rid of all "publishing" services, like node-rtsp-rtmp and just sending the stream to another host, where it could be restreamed either viat rtsp or directly into webrtc like with https://github.com/aler9/mediamtx (previously known as rtsp-simple-server). unfortunately the mediamtx does not accept TCP MPEG-TS streams as it seems.

If there is any other option to reduce the load/keep up high framerates on a Pi3+ or PiZero and to publish the stream via rtsp, I'm also happy to hear about that.

Actually, it is possible to use UDP with the --tcpout option. Sorry the option name is confusing. For example: picam --tcpout udp://192.168.1.2:8181

There is a trade-off between frame rate and resolution. If you want to increase the frame rate, you have to decrease the width and height of the video.
