Ok, it seems that a newer build of ffmpeg can understand and mux the mjpeg raw frames file. Still, that doesn't help me much, since I need to do this programatically... thank you for your time though! -- View this message in context: http://ffmpeg-users.933282.n4.nabble.com/Mux-encoded-video-data-directly-into-mp4-files-tp4667372p4667397.html Sent from the FFmpeg-users mailing list archive at Nabble.com. ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
