Reproduction Steps

The pullup filter should turn off, but does not, with the keyboard shortcut used to turn in on, shift + D, with the script cycle-deinterlace-pullup.lua installed.

1. Get the script cycle-deinterlace-pullup.lua from the repo.

2. Place it in ~/.config/mpv/scripts/.

3. Open mpv and play a video.

4. Press shift+D until the OSD reports the pullup filter is on:

   deinterlace: no
   pullup: yes

5. Press shift+D once more and then again repeatedly.

Expected Behavior

Deinterlacing should keep toggling between no deinterlace, deinterlace and pullup, and the ODS report so.

Actual Behavior

Nothing happens: the pullup filter stays on, and deinterlacing mode does not toggle any more. The ODS reports so on every subsequent shift + D press, staying on:

deinterlace: no
pullup: yes

No response

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

• I tested with the latest mpv version to validate that the issue is not already fixed.
• 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.
