I'm using giflib 5.0.5
Thanks in advance for any help.
Yep, this happens on Linux and that message also says that it supports only short videos encoded with other codecs than YUV or MJPEG. This restriction will be lifted when OpenCV will provide accurate search for MPEG4 on Linux. The solution is recoding your video or cutting the existing one using ffmpeg or something else.

I cannot open any video file (avi, mp4, mkv) - codecs not supported... Only JPEG or YUV4 codecs. RIP!

Try libav for this. http://libav.org
