[x264-devel] problem with interlaced encoding + compilation fix patch

[Erik Slagter]

The problem has been partly solved.

When using x264 instead of ffmpeg AND applying buffer size AND setting 
nal-hrd, the result is as expected. So imho this is a problem in both 
ffmpeg (doesn't set nal hrd and buffer options in the right order) and 
x264 (doesn't warn that --bff --tff don't have the desired effect if 
--nal-hrd isn't used).

Oh, btw this is a q&d hack to make x264 compile to current ffmpeg again.
