This seems like a very bad argument assuming there is a quality
hit and the speed gain is very

Is there really no quality hit for a 20% speed-up?

With the patch, we simply reuse the same source chroma line for each pair
of lines in the output and the yuv420 and yuv420p10 format of the decoder
can go to the v210 encoder without having to touch the pixels at all with
autoscale by swscale filter.
The end effect is swscale
