Description

Hi !

I have problem with opening RTSP stream from network camera.
This works fine using livemedia RTSP, but can not make it working on OpenCV.

capture = cvCaptureFromFile("rtsp://l:p@ip"); returns null pointer (on version compiled with gstreamer support), or hangs on (on version without gstreamer support).

Interesting thing that version compiled without gsstreamer support seems to work a bit better - as strace shows that library is trying to play the stream (RTSP DESCRIBE and PLAY commands) - but later - hangs infinitely.

For telling truth I'm not sure what the problem is, I suppose it is something about H264 stream encoding.

Are there any changes to make it working ? :)
Thanks in advance !

Best regards,
Grzesiek22

Maybe this is fixed by another version(s) of gstreamer and/or ffmpeg..? Probably this can't be fixed in opencv itself, but I'm only guessing here..

For this kind of connection you need to use svn version of opencv using its gstreamer backend

decision is right - after manual compilation of ffmpeg with x264 + OpenCV recompilation, it works. So changing bug status to invalid as it does not refer to OpenCV itself, but to supporting libraries (ffmpeg, x264 codec).

Regards and thanks for your support !
