Does a report exist for this bug with the project's home (upstream) and/or another distro?

No response

Expected behaviour

Running ffmpeg -listen 1 -i rtmp://192.168.1.235:1935/test -f h264 - | ffplay - should listen for an incoming stream, then display a video.

Actual behaviour

$ ffmpeg -listen 1 -i rtmp://192.168.1.235:1935/test -f h264 - | ffplay -

Error opening input files: Unknown error occurred
fd:: Invalid data found when processing input 0KB sq=    0B f=0/0

Steps to reproduce

  1. Have ffmpeg listen for an RTMP stream: ffmpeg -listen 1 -i rtmp://192.168.1.235:1935/test -f h264 - | ffplay -
  2. Stream something to the RTMP url.
  3. See error above.

I have tested with a build of ffmpeg omitting --enable-librtmp and can confirm this error does not occur.

At least in the past, librtmp builds also had connectivity issues while streaming (would randomly disconnect), prompting me to make my personal builds with it disabled. At this point I'm not sure if librtmp offers any useful features that ffmpeg's native RTMP doesn't yet have.
