Michael Niedermayer b548f2b91b ffv1 and ffvhuff havnt changed since a long time and noone proposed any
changes within 1 month after my warning so they are officially no longer
experimental and we will gurantee decodeability of files encoded with
the currenzt ffv1/ffvhuff in the future

Michael Niedermayer d925c516e4 huffyuv writes to AVCodecContext.stats_out only once every 32 frames,
presumably to reduce the size of the log file.
However, it doesn't clear stats_out on the other 31 out of 32 frames.
So the application (ffmpeg and mencoder) writes each stat line 32 times.
