Does not affect conversions to RGB formats of any bit depth. Does not
affect conversions if chroma sampling scheme is the same i.e. -f lavfi -i
testsrc2=r=1:d=5,format=yuv422p or yuv422p16le. Also does not affect if
only the luma plane is converted. So this has to do with converting the
chroma sampling frequency in swscale.
