 Summary of the bug:
 Ffmpeg ignores the -threads option with libx265. I've tried with libx264
 and works fine, it uses about 60% of processor, but with libx265 uses
 about 95% (full processor).
 I'm using Windows 7 SP1 on a Core2Duo 2GHZ CPU (2 threads).

 How to reproduce:
 {{{
 % ffmpeg -threads 1 -i salida.mp4 -c:v libx265 -b:v 500k -b:a 128k -preset
 superfast "salida2.mp4"
 }}}

 and just the same command but with libx264 instead libx265 works fine.
