I think he wants to software-decode into a user-provided AVFrame, which
this code does _not_ do. (It does only for hardware decoding - and for
old libavcodec versions which didn't have native reference counting
yet. I guess the hw decoding case could actually be applied to
software decoding too, but it still doesn't make an ideal example.)

Anyway, he want to override get_frame2. I'm not sure if that strictly
_requires_ reference counting, but maybe it's a good idea to use and
enable it.
