I need to remove MPEG-4 support from mpegvideo in order to upstream the
following code:

I'll need to extract mpeg4video from mpegvideo for the following reasons in
the Studio Profile:

- 10-bit video, mpegvideo.c is entirely 8-bit, I'll need to write a new
idct or use an existing (e.g ProRes) if applicable
- DPCM mode (a bit like h264's mode)

In particular I think this will break lowres. Is this ok or will the patch
be blocked?
