I can offer some help with the algorithm...
Cleaning up this codec is on the top of my personal TODO list! Last year I wrote
my own source code for indeo3 that approx. 50% smaller than the lavc one. It's
still uncomplete (delta frames must be implemented) but contains some fixes:
- it works both for big and little endian (the current lavc version doesn't work
on big endian machines properly)
- the algorithm was completely deobfuscated
- decoding tables are generated at runtime

So if you want to fix it fully I could send you my source. Otherwise I'll get
onto it by myself next month...
