Comment(by reidjr_at_lineone_net):

 I've updated the patch for trunk, as it looks like it will miss another
 release. I have also added a really minimalist patch. which just hard
 codes the loopfilter off.

 There is a strange thing I am seing though. Without the patch,
 multithreading h264 doesnt work, whatever you set max CPUs to. With the
 patch Setting the loopfilter option to off, doesnt save any overall cpu
 load, but does allow multithreading to work. Looks like either ffmpeg or
 underlying code has changed.

 I would suggest only applying this patch if you have multi-core cpu.
