My understanding of side data is that anything that is not essential to the
decoding phase is a side data. Pixel_format is essential because it tells
how bits are packed, thus it's an AVFrame field; however range, primaries
etc are often used after decoding, for rendering or scaling the picture,
and the decoded picture is usable even if that information is missing.
