No, sorry, x264 is the way forward, I'd rather fix the remaining latency
and quality issues than use a slow and outdated encoding.

This visual distortion is probably from the colourspace conversion (I
think), x264 is not affected because the size is rounded down to the
nearest even number, I will try to find a better solution for vpx but we
may end up taking the same approach..
AFAICT this is not related to this patch or other recent changes either.
