Generally looks good, but it occurred to me that the semantics of what
happens on failure in av_packet_ref() is unspecified, which might lead
to those uninitialized packets now being full of random data, which
might be dangerous.

So we might want to specify that on failure dst is reset to a clean
state and replace the call to av_packet_free_side_data() with
av_packet_unref().
