Comment:
Okay, I was wrong, I used yuvview (hex view in settings) and your file is
indeed using in hex 0x3ac 0x200 0x200. So the bug here is not about the
scale: even normal production of a png of -vf extractplanes=y will produce
65283 Y only png. I suppose the idea that 10 bit value in png 32 bit will
be just *64 is wrong. Sigh.
