I don't know if it can be made into a proper project easily and
if it is worth it, but our MPEG-4 decoder and possibly encoder
should have some issues to clear out.
For example there's some issues with non-mod 16 resolutions and
4mv where we are not correctly limiting them.
It would be interesting to investigate what other encoder and
decoders do and change our code to work as well as possible
in all cases.
Then there is the interlaced case where we have a TODO since
we just use a 2*8x8 instead of 16x8 MC function.
There might be more stuff.
