Description
Hi
I've had a few bugs where ffmpeg would fail to read an mpg video returning :
[mpeg1video 004910a0] mpeg_decode_postinit() failure 004910a0] too many threads
[mpeg1video
It seems this error comes from libavcodec used to build ffmpeg. This was additionally corrected on July 9th in libavcodec so probably releasing a new version of the opencv_ffmpeg.dll dll would solve this.

Ok don't know what's going wrong here but I'm also getting these messages on some mpeg4 videos now (except message start with [mp4video ) which used to work flawlessly before (mpeg videos used to work too)
Is there a way to recompile opencv_ffmpeg.dll myself?

Ok ended up recompiling the latest ffmpeg version (head from 2011/12/15) and the new dll solved all issues with too many threads error
Definitely a must have in my opinion - dll is huge though (40MB compared to 7.5MB of the previous one)
Attached is the compiled dll
- Status changed from Open to Done
- (deleted custom field) set to fixed
