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.
Regards,
Marton
