Thanks. There is one issue I found:

You are setting &ctx->video_st->metadata from the VideoInputFrameArrived 
callback. That runs in a separate thread from the main thread 
handling read_packet calls, and you can only invalidate 
video_st->metadata in the main thread. So I suggest to store the timecode 
string in a context variable, and do av_dict_set in 
ff_decklink_read_packet after avpacket_queue_get.
