I was interested in how it compared to a couple of pcs here.
6-7 year old laptop with pentium-m @ 2ghz - 43.481s
desktop pc with i5-2500k single thread - 12.891s
desktop pc with i5-2500k threads=4 - 4.596s
desktop pc with i5-2500k threads=8 - 4.070s
of course ffmpeg libs have plenty of x86 optimisations.
