Reproduction Steps

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.

Use --teletext-page to select page of teletext and subtitles you want to see.

--teletext-page=199 for Swedish, --teletext-page=299 for Norwegian and so on, as mediainfo listed them.

[drejjmit]

Sounds more of a workaround than a fix. Makes more sense to split it into selectable subtitle tracks like other players.

[kasper93]

Teletext is much more than just subtitles, and we support it all. Teletext is one stream/track, it's decoder job to display pages you would like to see.

Of course ffmpeg could expose pages information (in limited cases where it's available) and we could multiple the same track for each page, but this is quite low priority, patches welcome.
