This looks wrong, we don't pass pointers to an AVClass around. The
logging functions want a pointer to a pointer to a AVClass either way
(ie. a AVClass pointer embedded in another struct)
If you want to pass a generic logging context, make it accept a void*,
The same for all other methods where this applies.
