We're still supporting old x264 versions, so you should add some
considerations for 9 bit pixfmts. On X264_BUILD < 153, just check the
value of x264_bit_depth.
Is there much point in continuing to support 5.5 year old x264? We could
drop a lot of ugliness, including the abominable X264_init_static().
Afaik we tend to support what's shipped with not yet EOL'd big distros
like Debian and Ubuntu. I assume Michael's Ubuntu setup is one of those,
and it has a libx264 without X264_CSP_I400, for example.
