[FFmpeg-devel] Official status of FFv1?

[Jason Garrett-Glaser]

Here's some benches for you, Baptiste.  Source: standard foreman CIF.

Note of course in practice you would use multiple threads with x264,
which would put it well ahead speed-wise (since FFV1 cannot be
frame-multithreaded in the typical way).
