Did you even read the link I passed? That patch makes x264 not 
initialize any mutexes if no threads are specified since it's not going 
to use them anyways.

When I moved the initialization code from ffmpeg.c to phtreads.c, that 
code would only be called if -threads x was given. If only 1 thread was 
used, it would crash x264 attempting to create mutexes (without running 
the init code). This is a bug in x264.
