Well, I thought the /* private fields */ meant that the lavf internal
variables are last so that they can be added/removed/modified at will
without breaking ABI, which only works if they indeed are the last ones.

But if that is not the intention, priv_class can be put last (it is public).

As for the minor bump, seems I forgot that for this one.
