Btw. after thinking about it a bit, I think it is better to read only
the things you need like width and height from the header in
read_header and then seek back to the start of the file.
Then in read_packet you can just read the header first and continue from
there.
That means less data in the private context (possibly none at all?),
using the generic index/seeking support will be easier and it should
also work better for supporting video, since I think you will have to
copy (most of) the header into the video packet anyway.
