Fallback stream for RTSP

[alex-rsk]

Hello. Firstly, thank you for impressive work.

I want to ingest RTSP stream and produce ...another RTSP stream, so my goal is to restream.
But, suppose my RTSP source is unreliable, and sometimes breaking down, due to network weather.
Can I manage with go2rtc a fallback source, e.g. some local ffmpeg-generated stream, which is always working?
So i'd want to obtain seamless stream, which doesn't depend of network weather and source problems.

You can set multiple sources for your stream. But I've never tested this function as a fallback. You can try.

It would also be great to have an api to switch off a stream to some static image. This would be really helpful for tools like frigate which are constantly restarting their video processing if some stream gets unavailable.

Switching active stream to something else is a hard task. Because you should pass same encoding data (resolution, codec with all params, etc).

It would be no problem if the stream is interrupted for a moment, because frigate will restart the process anyway if there is an error. The static image could also be using a very low resolution to save bandwith and compute power...

Most video protocols should not change resolution and codec during video transmission.
