This is the extra info I got from the ffmpeg output... didn't notice
it before (without the -vpre default):
[libx264 @ 0x831c050]broken ffmpeg default settings detected
[libx264 @ 0x831c050]use an encoding preset (vpre)
I wonder if this is actually a bug in libx264. Shouldn't it use some
default when detecting "broken" default settings?
Maybe I should report upstream to both (ffmpeg and libx264)?
