Inspect the CPU to determine number of threads to use while processing

Right now it's hardcoded as 8 ffmpeg processes to run in parallel so speed up the frame grabbing. Until ffmpeg is directly incorporated, I have to be more careful that the number of threads is below the number of cores on the CPU.

You could use one of these methods:

  • grep -Ec 'processor\s+\:' /proc/cpuinfo
  • nproc
  • lscpu -p | grep -Ecv '^#'

tested on Xubuntu Linux ...
