Comment (by 11rcombs):
$100 to whoever fixes, where "fixes" is defined as "ffmpeg -ss <time> -i
<10bit_h264_file> -vframes 1 -pix_fmt rgb24 out.png" produces output with
no discernible image-wide discoloration as compared to the same cmdline
without the -pix_fmt, and the amount of banding in the image is comparable
to that in the same frame downsampled using ImageMagick.
