Describe the issue

If you stream via rtmp and receive via rtsp the stream freezes after three seconds. Receiving with rtmp does work.

Describe how to replicate the issue

1. https://github.com/aler9/rtsp-simple-server#from-obs-studio
2. Watch rtsp stream using mpv

Seeing the same issue with the current GIT version. Streams published via RTMP aren't available as RTSP.

Hello, i was able to replicate the issue, it seems specific to mpv player.
ffmpeg, GStreamer and VLC all works when reading with RTSP a stream that is being published with RTMP.
mpv doesn't work when the stream contains video and audio, or contains audio only.
Will investigate further.

Thanks for reporting this bug, it has been fixed. It was caused by the fact that the server was advertising payload type "96" for the audio track, but was encoding audio with payload type "97". You can check that everything is all right by using this nightly version:

For the record I still cannot have a RTMP source read back as RTSP, the logs show:

[aler9]

@Enverex that is evidently another problem. Please open another issue and follow the instructions in order to provide data needed to replicate the issue (for instance, which client are you using?).

[Enverex]

Will do.
