These fields are supposed to store information about the packet the
frame was decoded from, specifically the byte offset it was stored at
and its size.
However,
- the fields are highly ad-hoc - there is no strong reason why
specifically those (and not any other) packet properties should have a

Since these are external encoders not under our control, we cannot test
the encoded output exactly as is done for internal encoders. We can
still test however that the output is decodable and produces the
expected number of frames with expected dimensions, pixel formats, and
timestamps.

A minim
When decoding jp2 with palette, [color space] is determined when calling
[opj_decode]. Because of this, [pix_fmt] should be set after decoding.
Otherwise, [pix_fmt] will be set to AV_PIX_FMT_GRAY8 and output an wrong
image.
