Can stream via SRT to MonaServer/MonaTiny but cannot access that stream

[maltris]

Hello,

I am trying to utilize MonaServer/MonaTiny to stream to a server and then fetch that stream from there. With RTMP this works perfectly fine, however I wanted to check out SRT:

ffmpeg -re -i ~/myvid.webm -f mpegts 'srt://127.0.0.1:9710/?streamid=1'

ffplay "srt://127.0.0.1:9710/?streamid=1"

The sender transmits, but the receiver will not be able to fetch any stream. Just empty.

The debug log looks like this:

My setup is running in docker but for debug purposes in host networking mode:

docker run --rm -it -v "./MonaServer.ini:/usr/local/bin/MonaTiny.ini" --net=host --name=mona monaimage

The libsrt is 1.5.3 (from Alpine 3.19), MonaServer is commit 13b4eb4.

Any help would be appreciated!

Have you had any luck with it? I have the same problem

Not really, I kinda gave up on it and didn't investigate further. Seems like the MonaServer is not as actively developed as one wished, I tried a couple things with nginx-rtmp, which has its own flaws.

Thanks for your answer, RTMP Server on Mona works perfectly fine and i just found a way to use SRT with mona but currently it does only work for me on the Windows Mona Server and not the Docker Version.
The SRT server is not really usefull, because SRT doesnt work that way.
But you can use publications and define the in and out link as srt.
This works great with as little latency as possible.
If you have more questions to my way feel free to ask.
