[FFmpeg-devel] [PATCH] Escape 124 (RPL) decoder

Per subject, decoder for Escape 124, one of the three known formats
for video in RPL
(http://www.wiki.multimedia.cx/index.php?title=Escape_124).  I've
tested this on some samples from the original Tomb Raider, and the
decoder appears to be working flawlessly.  As far as I can tell, the
codec description on the wiki is accurate; however, it took me a while
to realize that depth=0 is legal in the codebooks.

This implementation is extremely prone to crash on invalid streams due
to reading past the end of the buffer.  Any suggestions on how to make
this safer?
