MJPEG lossless rotate is a utility to rotate MJPEG Videos by 90 degrees without any loss of quality. Many digital cameras record video using MJPEG. The main purpose of MJPEG lossless rotate is to rotate digital camera videos made in portrait mode.
Actually I think this is a worthwhile project, but I'm afraid it currently doesnt work. I tried to rotate a Motion Jpeg AVI generated by a Canon IXUS 55. The original plays perfectly under a number of Linux players - using gmplayer as a reference. However the rotated one must be missing some header information. The error is: FATAL: Could not initialize video filters (-vf) or video output (-vo) VLC could play it (audio fine), but the colour information for the video was completely wrecked - B&W with coloured bands across it. Kaffeine crashed immediately trying to play it (Kaffeine is an awful video player anyway, its much better as a music shuffler). The good: the program launched and 'worked' pefectly, it just didn't do what it was supposed to do. Please keep working on it and good luck!
