I can't speak for FOSS video stuff, but when I'm encoding H.264 with
Quicktime on OSX, it most definitely does use all of the CPUs it can
get. On Linux, I note that pbzip2 will use all cores to compress
files, and git can be told to do some CPU-bound things in parallel.
There's something satisfying about seeing 390-odd% CPU usage in top.
