Yes, the load was raised by 100%, not that is really huge (from 6% - 9%
to 12% - 15%). But on 29 running ffmpeg instances it matters. Thou I am
still trying to understand where the bottleneck is when I try to pass
more than 32+ instances, but that is a matter for a new subject.

Dependent on a stream I am "burning" subtitles into a video and mapping
out only those streams that I am interested in, so one audio + one video
(optionally burned subtitles). Everything else (deinterlace) is done in
decoding stage.
