[FFmpeg-devel] [WIP] GSoC P frame support for FFV1 codec

[Станислав Долганов]

New formula for residual calculation, which reduced compressed sized
significantly, but it is still a bit larger then in case if all frames are
I. I think it because of coder context changes to much from I frame pixel
value to P ones.

Also more fate test references were generated.
