I should clarify that threads=8 for ffms2 from my previous post is cpu_threads/2. So you can try with that cpu_threads/2.

I got curious and made a couple of tests using different source filters with Atak's SeekTester 1.2. I used the default frame limit of 1000 frames. As the source I took the "Letter - SHE'S.mkv" (VP9 Video 1080p). My CPU is a Core i5 third generation (2 physical cores plus hyperthreading). I used the default thread values for all source filters which would be 4 for this CPU.

Ok, these results are only for this specific VP9 source file. Other source formats may behave differently, but I find this very interesting. Any comments?

Thanks for sharing.
