Comment (by mkver):

 avpacket_queue_put() calls av_packet_make_refcounted() on the packet
 before putting it into the queue. Because the packet is not already
 refcounted, this will make a copy. So everything should be fine. But I
 don't have a decklink device at all, so I can't test this and am therefore
 not closing it. Have you actually experienced a use-after-free yourself in
 the scenario you describe?

 (The handling of video avoids copying the data, instead adding
 references.)
