av_copy_packet in a muxer sounds strange, in libav we do not have such
function since avpackets are refcounted.
ff_alloc_packet2 from what I can recall keeps 1 packet cache in
avcodeccontext, but then if you always copy/duplicate the avpacket
produced it gets a little pointless having it, even worse if you have mt
encoders.

Today I'll be traveling so I might look at it when flying to Berlin,
thanks a lot for your effort =)
