I've asked this many times regarding VOBs, now I ask regarding M2TSes.

Is there some parameter that can be set to force FFmpeg to report what's actually in PES headers instead of allowing it to make things up?

'-vf framecrc' reports this:

         DTS         PTS
    +-----------+
1,  ¦ 504219120 ¦ 504219120,      960,     1400, 0xdffda506
    +-----------+

The actual situation is this:

PES header
   stream_id: BD (private stream 1)
   PES_packet_length: 1408
   PES_scrambling: 0
   PES_priority: False
   data_alignment: False
   copyright: False
   original_or_copy: False
   PTS_flag: True
 +-----------------+
 ¦ DTS_flag: False ¦
 +-----------------+
   ESCR_flag: False
   ES_rate_flag: False
   DSM_trick_mode_flag: False
   additional_copy_info_flag: False
   PES_CRC_flag: False
   PES_extension_flag: False
   PES_header_data_length: 5
   PTS: 504219120

There is _no_ DTS.

Is this nonsense the cause of so many discontinuous DTS alerts (and other 
strangeness)?
How consistent is pretend DTS values across all FFmpeg tools and filters?

--Mark.
