MakeMKV generates corrupt subtitle track when using custom track names

#1 Post by CaptPicard » Mon Mar 25, 2024 3:04 am

MakeMKV 1.17.6 appears to be generating a corrupt subtitle track when I try to convert the "Pirates of the Caribbean: The Curse of the Black Pearl" blu-ray disc into an MKV file and use a custom name for some subtitle tracks. It seems to be inserting an extraneous 0x74 byte into the beginning of a track element of the MKV file, corrupting that track. It reports no errors when reading the blu-ray disc and creating the MKV file.

Here are my repro steps:
  1. Open the "Pirates of the Caribbean: The Curse of the Black Pearl" blu-ray disc in MakeMKV.
  2. Unselect all titles except for the first title (with 17 chapters).
  3. Set the name of this selected/enabled title to: Pirates of the Caribbean: The Curse of the Black Pearl
  4. Within this selected/enabled title, set the chapter names to:

    1. Opening Credits / A Pirate's Life
    2. Pirates Ye Be Warned
    3. Elizabeth's Rescue
    4. The Black Pearl
    5. Welcome Aboard
    6. The Hunt
    7. Finding a Crew
    8. Aztec Gold
    9. The Treasure of Cortez
    10. Keep to the Code
    11. The Battle
    12. Stranded Again
    13. The Curse
    14. The Trojan Horse
    15. The Curse Is Lifted
    16. End Credits
    17. Empty
  5. For the first 2 English audio tracks (LPCM and Dolby Digital), leave them at their default names.
  6. For the final 3 English audio tracks, set their names to:

    Commentary with Director Gore Verbinski and Actor Johnny Depp
    Commentary with Producer Jerry Bruckheimer and Actors Keira Knightley and Jack Davenport
    Commentary with Screenwriters Stuart Beattie, Ted Elliott, Terry Rossio and Jay Wolpert
  7. For the first set of English subtitle tracks (regular and "forced only"), set their names to: SDH
  8. For the 3 sets of English subtitle tracks (regular and "forced only"), set their names to:

    Commentary with Director Gore Verbinski and Actor Johnny Depp
    Commentary with Producer Jerry Bruckheimer and Actors Keira Knightley and Jack Davenport
    Commentary with Screenwriters Stuart Beattie, Ted Elliott, Terry Rossio and Jay Wolpert
  9. Click the Save button to create the MKV file.
When I then open this MKV file in MPC-HC version 2.1.7.4, it shows all of the subtitle tracks I selected in MakeMKV except for the last one. That last subtitle track (Commentary with Screenwriters Stuart Beattie, Ted Elliott, Terry Rossio and Jay Wolpert) is missing.

When I examine the MKV file using the "Info tool" in MKVToolNix GUI version 82.0, it shows all of the subtitle tracks as expected except for that last subtitle track. In the location of the MKV file where it should have that last subtitle track, the MKVToolNix info tool shows "Unknown element (ID: 0x74ae)".

Notice how all of the tracks except for the corrupt one start with an 0xAE byte to represent the TrackEntry element. However, the corrupt track starts with an 0x74 byte, which isn't a valid starting byte to represent any MKV element. But right after that 0x74 byte is an 0xAE byte, which is likely the desired start of this track element.

If I skip putting the "Commentary with Producer Jerry Bruckheimer and Actors Keira Knightley and Jack Davenport" custom name in the middle set of English commentary subtitle tracks (regular and "forced only"), then the MKV file that MakeMKV generates includes all of the subtitle tracks without corruption.
