Wrong mailing list. ffmpeg-devel is only for patch submissions and discussions related to the development of FFmpeg. Questions involving the usage of the FFmpeg libraries should be asked at libav-user. See http://ffmpeg.org/contact.html _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
