Playback position not always saved when closing window via close button

[FusionGold]

Overview Description: When using an external MPV configuration with save-position-on-quit = yes, the video playback position is consistently saved when quitting with the q key. However, when closing the window by clicking the "close" button, the playback position is not always saved.

Steps to Reproduce:

1. Open a video with save-position-on-quit = yes enabled in external mpv config file.
2. Click to seek to a specific position in the video.
3. Close the window using the "close" button instead of the q key.

Actual Results: Playback position is not always saved when closing the window using the "close" button.

Expected Results: Playback position should be saved consistently when closing the window, just as it is when quitting with the q key.

Version: 0.27 (installed via Arch's extra repo)

Additional Information: Running Arch Linux, GNOME.

Would you be able to test with the git version? I think this might have been fixed already.

Thank you for your response. I installed the celluloid-git package from AUR, version 0.27.r35.g8356432-1, but unfortunately, the issue still persists.

Dear dev, I'm afraid the issue has not been resolved. I tested with 3f2aef9 (installed via celluloid-git), but the problem still persists. For test, I used a single line configuration in my mpv.conf that is save-position-on-quit = yes and did choose the file correctly. Disable loading of file and add --save-position-on-quit in the Extra MPV Options UI also not working.

Can you try reproducing the bug again with logging enabled and post the log file here?

I have a video file called video_for_test.mkv, and i play it for 3-5 seconds, and then close it. For test convenient, alias test='rm ~/.config/celluloid/watch_later/*; rm /tmp/celluloid.log;G_MESSAGES_DEBUG=all celluloid video_for_test.mkv --mpv-msg-level=all=trace > /tmp/celluloid.log'

Test with click close button: close_button.log now, do cat ~/.config/celluloid/watch_later/*:

# redirect entry
# redirect entry

Test with press q: q.log now, do cat ~/.config/celluloid/watch_later/*:

# redirect entry
start=3.670000
# redirect entry

Also to mention that this is an occasional issue. I tested by clicking the close button five times, and one time the watch_later recorded the correct position.

Test file with additional stderr message: (not sure if it's helpful.) This time, alias test='rm ~/.config/celluloid/watch_later/*; rm /tmp/celluloid.log;G_MESSAGES_DEBUG=all celluloid video_for_test.mkv --mpv-msg-level=all=trace &> /tmp/celluloid.log'

Test with click close button and redirect stderr: close_button_stderr.log

Test with press q and redirect stderr: q_stderr.log

Is close_button_stderr.log from when it failed to write a watch_later file?

https://github.com/celluloid-player/celluloid/commit/3f2aef9d829bd99f3db11c000126bf1cccd2fee0 fixed a crash on exit that could prevent the watch_later file from being written, but it doesn't look like there's a crash happening in your log. I'm unable to reproduce the bug with the fix applied.

[FusionGold]

Yes, for the close_button_stderr.log case, I immediately ran cat ~/.config/celluloid/watch_later/*, and it showed # redirect entry # redirect entry with no time logged. It's wired. Not sure if it's an OS specific issue, a Btrfs filesystem problem, or just an isolated case.

[FusionGold]

if it's an OS specific issue

Can confirm no such issue with the flatpak version. The issue only exists when using the celluloid package from arch extra repo, or using celluloid-git from aur.

I'm experiencing the same on 0.27 on a freshly installed Ubuntu 24.10, both with the snap and the ppa:xuzhen666/gnome-mpv versions I have to use q for the position to save, closing with the application with the GUI close button won't save the last position
