[FFmpeg-devel] [PATCH] Add FourCC SP54

Stub about the codec: http://wiki.multimedia.cx/index.php?title=Sunplus_JPEG

MPlayer docs list a bunch of other FourCCs, but there are only samples
for SP54, and none of the others show up in the "Popular codecs on the
web not supported by FFmpeg" thread, so it's likely the other FourCCs
aren't actually used.  Adding them would be trivial, though.

Since FFmpeg already supports the codec, the patch is trivial.  The
samples appear to decode correctly.
