Reproduction Steps

1. Play the .ts file

Expected Behavior

4 selectable subtitle tracks.

Actual Behavior

1 selectable subtitle track with all 4 teletext subtitle streams on top of each other.

Log File

output.txt

Sample Files

dvb_teletext_example.zip

I carefully read all instruction and confirm that I did the following:

• I tested and confirmed that the issue exists with the latest release version or newer.
• I provided all required information including system and mpv version.
• I produced the log file with the exact same set of files, parameters, and conditions used in "Reproduction Steps", with the addition of --log-file=output.txt.
• I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
• I attached the full, untruncated log file.
• I attached the backtrace in the case of a crash.

Start by reproducing the issue with the attached dvb_teletext_example.zip and reviewing output.txt. Trace how mpv handles the four DVB Teletext subtitle streams from the sample, then verify that each language is exposed as a separate selectable subtitle track instead of being layered together.
