133	CJPG files have chroma problems	cehoyos		"(issue 777)
CJPG files are decoded fine with mplayer -vc ijpg, they are mostly green with ffmpeg (and grey with mplayer -vc +ffmjpeg).

The problem is that the image data is full of restart markers (FFDx) that make libavcodec fail to decode chroma planes (Kostya).
