[MPlayer-dev-eng] BMP Demuxer & 4bpp MS RLE

This is a momentous day in the history of MPlayer
development. This is the day that MPlayer supports 4-bit Microsoft
RLE. Really. I don't even know if there ever were AVI files with 4-bit
RLE, but if there are, you can count on MPlayer to play them.
But here's the kicker: Since I needed a way to test the support
and there are no sample AVIs to be found, but I can create sample BMP
files, I added a BMP image "demuxer". Actually, it just continuously loads
the same frame over and over again, twice a second. It works. Maybe we can
apply this to other still image formats? A JPEG "demuxer" that uses the
same optimized IDCT routines as the MPEG libraries and uses the Xv
Bonus: The BMP demuxer supports seeking...heh...oww, hey! Stop
throwing things at me...:) Unfortunately, the PNG vo target makes MPlayer
crash, so you can't use MPlayer to transcode from BMP -> PNG.
Oh yeah, and you can find samples in incoming/bmp-files.
