The -sameq option is probably the most misused FFmpeg option and it
probably doesn't do what you think it does. The old documentation
(ffmpeg -h) implied that -sameq meant, "make the output the same
quality as the input", but this is not necessarily true. The
documentation has been updated, but could still be more descriptive.
