Comment (by cehoyos):
Replying to [ticket:2640 b_jonas]:
> I believe that direct color space conversion to gbrp should not add this
much overhead if I am dropping most of the output frames anyway, because
the color space conversion should be needed only for the frames kept.
I strongly suspect you can achieve that higher performance if you put the
fps filter in front of the scale filter in your filter chain.
