Comment (by er.anshul.maheshwari@…):

 In Mov demuxer following function for First frame of Closed caption.

 Inside mov_read_packet
 while calling av_get_packet sample->size must be zero and 8 bytes before
 that must be discarded or parsed. In present scenario one atom is not
 parsed and that atom header act as garbage for Closed caption decoder.
 ret = av_get_packet(sc->pb, pkt, sample->size);
