Reproduction Steps

Load MPV with a file-specific option for --start:

mpv --{ start=5 video.mp4 --}

Run the commands in MPV console:

set file-local-options/start none
set start none
playlist-play-index current

It will reload the video, but it will be at the start position of 5, instead of having no start position and playing back at 0.

However, if you use the global option --start=5:

mpv --start=5 video.mp4

Then you are able to clear the option, reload the file and have it play the file from the beginning:

set start none
playlist-play-index current

---

This also gets a little more messy if you try to clear these options from a script. If you set the global --start option in MPV (mpv --start=5 video.mp4) and then in invoke mp.set_property('start', 'none') in a JS script, it does not seem to clear the value, because then running mp.command('playlist-play-index current') will still set the starting position of the video to 5 seconds.

Expected Behavior

Setting properties start and file-local-options/start to none (clearing them) should allow you to reload the playlist without any start position via playlist-play-index current.

Actual Behavior

After setting properties start and file-local-options/start to none and then reloading with playlist-play-index current, the starting playback position still uses the previous start value before it was cleared.

No response

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 console commands involving start, file-local-options/start, and playlist-play-index current, then compare the global option path with the file-local option path. Check the handling behind the set command and the JavaScript mp.set_property API; done means clearing both properties causes a reload to begin at position 0.
