Paul and all, do you have any chances to view my patch from Feb,19? I assume I'\ve fixed all you've kindly pointed out and even more. Please correct me if I'm wrong. The only question remaining is - are you ok with the combination of threading and conditional filter operation (= do something if it is really required only) or you prefer to split it to 2 separate corresponding patches. I'd prefer the first option because it makes git ffmpeg repo and ffmpeg development cleaner not dirtier...
