But FFV1 is lossless, so there is no quality range.

Hello,
I'm currently working on GSOC 2016 project for upgrading FFV1 codec with an
ability to use P frames. Maybe some of you have any suggestions or
recommendations.
While working on qualification task I implemented a simple modification of
codec to encode P frames without motion compensation,
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.

Hello, I have implemented simple p frame support for FFV1 codec as part of
the GSoC qualification task, so now it for every non key frame stores a
"residual" instead of a frame itself.
The patch file is attached to this message. It also replaces reference
files for FATE tests, cause relative
e relative checksums and filesizes were changed.
