When I started to convert my vdr recordings to h264 using ffmpeg
-vcodec libx264. I saw that running it without -threads or with
-threads set to 2, it used the same cpu usage. When I changed it to
-threads 3 I started to see more than 100% usage. Perhaps decoding
should also use -threads 3 to see it run on more than one cpu ?
Perhaps you can modify the ffmpeg profiles?

This was on a Core 2 Duo 1.8GHz. Hope this helps somebody.
