That's good. :)

I can't see anything bad with this approach. BTW, limit of 64 maximum
threads is absolutely random, maybe it should be smaller or bigger, or
no limit at all.

No, I don't.


I've made patch, which add -b (--benchmark) command line option. In
benchmark mode bino doesn't play audio and don't use any timesync for
video, playing video as fast as possible. Each 250 frames it show
current FPS value.

Then, I build two versions of bino with this patch: one on vanilla
ffmpeg, and one on ffmpeg-mt.

The results of benchmarking are included.

Regards,
Alexey.
