I am trying to do some crop detection on an MJPEG (in quicktime
container) file I captured with mjpeg_tools and it's not working.
When I put some debugging into vf_cropdetect.c, it revealed that
checkline() is being called with a bpp=2, however checkline does not
support bpp=2.
Is this a bug or intentional behaviour? Here is what mplayer -vv has
to say about the file format:
