[FFmpeg-devel] [RFC] Dealing with flipped videos

Searching through the Facebook logs of failed videos with ffmpeg, I
found a video clearly recorded on some type of mobile device that's
stored as "DIB"; rawvideo.  Attached patch adds support (turns out its
RGB565).  However, there's one problem: as the video is in Microsoft
bitmap format, it's flipped.  Virtualdub, however, decodes it
correctly.  Sample is in incoming as facebook_dib_flipped.avi.

So the question is--what is the best way to deal with videos that are
coded upside down?
