Comment (by andreasg):
I don't really understand the question about setting the range. I still
kind of consider it to be a bug that converting YUV to gray takes that
long with sws_scale. However, this conversation has been very helpful for
me in understanding some FFmpeg internals so that I can work around this
issue.
You can close the bug if you think that this is the intended performance.
