avc1 is a pointer to a pointer to a AVClass

or avc1 is a pointer to an arbitrary struct whos first field is a pointer to
a AVClass struct

or in OOshit talk avc1 is a pointer to an instance of a subclass of a class
which contains exactly one field, and this field is a pointer to a AVClass

all the same just getting more obfuscated as you get closer to CS dreamland
