probably, with the latest cap_ffmpeg.cpp (http://code.ros.org/svn/opencv/trunk/opencv/modules/highgui/src/cap_ffmpeg.cpp) the problem is fixed. If not, please, reopen the ticket

In Ubuntu 10.04 with the last stable version (2.3 rc) and the correct version of the cap_ffmpeg.cpp file, I still get the problem.

I also compiled the last ffmpeg version and nothing changed.

I posted on the OpenCV yahoo group before coming here : http://tech.groups.yahoo.com/group/OpenCV/message/81451

The solution provided in the ticket #120 worked for me. You might also need to use the hurry_up property of the AVCodecContext to speed things up.
