 Summary of the bug: Regression in the JPEG2000 decoder. I see the problem
 using either libopenjpeg or jpeg2000 as the decoder. It seems that FFmpeg
 erroneously recognizes the video as rgb48le when it is really yuv422p10le.
 I have a version of FFmpeg from 3/28/2013 that does not exhibit the
 problem.

 How to reproduce: Try to decode JPEG2000 video with the following command:
 ffmpeg -i "J2K Decoding Regression.mkv" -f rawvideo NUL -y


 {{{
 ffmpeg -i "J2K Decoding Regression.mkv" -f rawvideo NUL -y
