Thanks you for these response.

[rtsp @ 0x39da4c0] UDP timeout, retrying with TCP

Did you try forcing tcp? It may help if a camera timeout is the issue.

How to force tcp?

Hi,

I try to read a stream video with the command line : ffmpeg -i rtsp://192.9.200.121/h264 -y -map 0 -t 5 -c copy -f matroska  _capture.mkv

And I get this error :

[rtsp @ 0x39da4c0] method SETUP failed: 454 Session Not Found
[rtsp @ 0x39da4c0] Could not find codec parameters for stream 0 (Video: h264, none, 1280x720): unspecified pixel format
Consider increasing the value for the 'analyzeduration' and 'probesize' options

These are the relevant lines, everything else is just a consequence.
Consider increasing verbosity.
