  mxfdec: Don't crash in mxf_packet_timestamps() if current_edit_unit overflows
  mxfdec: Zero nb_ptses in mxf_compute_ptses_fake_index()
  mxfdec: Sanity check PreviousPartition
  mxfdec: Never seek back in local sets and KLVs
  mxfdec: Move the current_partition check inside mxf_read_header()
  mxfdec: Fix infinite loop in mxf_packet_timestamps()
  mxfdec: Check eof_reached in mxf_read_local_tags()
  mxfdec: Check for NULL component
  mxfdec: Make sure mxf->nb_index_tables > 0 in mxf_packet_timestamps()
