RTMP INPUT/OUTPOT ERROR FROM FFMPEG #309

hello,
I configured rtmp nginx module git with latest nginx 1.19 ffmpeg-git and i am having some intermittent random ffmpeg errors when trying to read with ffmpeg -i rtmp://..

I can see that in the ffmpeg debug log. So my question is what versions are you using for nginx/ffmpeg/rtmpmodule that would be stable? I am pretty sure it is a bug somewhere

Thanks

Why don't you post the ffmpeg debug log, and the nginx log in debug mode?

The Problem is that it got logrotated. Which nginx version/ ffmpeg version are you using ? Do you mind sharing? I will post as soon as i see the bug again, it just happens randomly sometimes after days..

Any ideas please? Appreciate if you can point me what is a good stack to use : nginx version / OS / ffmpeg version that you are using in production

Thank you

The errors are fairly normal from ffmpeg, try turning down the log verbosity. This has nothing to do with nginx.

How can i optimize nginx rtmp to handle a user broadcasting with bad connections? Can you please advise if there are some parameters that can help to handle such cases?
Thanks

IS that SRT compatible with nginx rtmp module? do you use softwares like OBS to stream ? is that compatible?

As a note here, using SRT with the ffmpeg listener is currently bugged. If the SRT stream disconnects, the socket gets hung and will cause issues, and ffmpeg needs to be restarted. Make sure this is not what is affecting you first.
