Video stuttering on Windows 11

steo86 commented 1 week ago

mpv Information

Hello,

I have the issue that video on Windows 11 is stuttering. Display refreshrate is set to match the video (23,976hz) and also when checking with "I" there are no framedrops. It´s just stuttering. 

This happens:

- When switchen between windows. Means swtichen between mpv and other windows with "alt+tab".
- Video is running fine for about 20-60 minutes fine without stutter in fullscreen and then begin to sutter suddenly.

To fix it I need to:
- Pause the video
- Jump to another Windows with "alt+tab"
- Jump back to mpv with atl+tab
- Unpause video

Then video is running fine again for a few minutes and starts stuttering again.
I have this with my customized config-file but also with a plank downloaded MPV without any config.
So it seems to be independent form the config ander shaders etc. In logfile no error is visible.
Someone haveing similar issues?

Other Information

- Windows 11 24H2
- Latest mvp build form git
- Nvidia RTX 4070 + I5-14400F

Sample Files

No response

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

[X] I tested with the latest mpv version to validate that the issue is not already fixed.
[X] I provided all required information including system and mpv version.
[X] 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.
[X] I produced the log file while the behaviors described in "Actual Behavior" were actively observed.
[X] I attached the full, untruncated log file.
[X] I attached the backtrace in the case of a crash.

outlog.zip Attached a logfile with logging options set to maximum (--msg-level=all=trace) Video was running fine first minute and then began stuttering. Then I pressed pause --> see line [ 105.444][v][cplayer] Set property: pause -> 1 So stuttering began a few seconds before that line. Maybe someone is seeing whats going wrong?

I have the same issue, stuttering on Windows 11 running the latest NVIDIA driver, no frame drops reported by mpv but the video is clearly dropping frames sometimes.

The only way I was able to work around the issue is to downgrade NVIDIA driver to 551.86. Not sure if there's any way to avoid the issue while running the latest driver.
