Reproduction Steps

Have

vf=d3d11vpp=scale=2:scaling-mode=nvidia:format=nv12
interpolation
video-sync=display-resample

Then play any video. The video will be frozen, but the audio will play. UI is fine.

Expected Behavior

Video plays correctly with sound.

Actual Behavior

A snapshot of the video frame is shown, frozen in time, audio keeps playing. If you skip to a different timeframe, it shows a different video image, still frozen though.

Log File

output.txt

Sample Files

Happens with all videos it seems.

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.

Ah, after doing more testing, it looks like interpolation and video-sync are the culprit,

vf=d3d11vpp=scale=2:scaling-mode=nvidia:format=nv12

Doesn't matter.

Can you try vo=gpu-next?

Never mind, I can reproduce locally.

Hello,

The issue is fixed for most videos, but still sometimes happens, here's the log file for the one that happens: output.txt

Sometimes now some videos don't even open: output2.txt

Does it only happen with vf=d3d11vpp=scale=2:scaling-mode=nvidia:format=nv12?

No, it happens with just

interpolation
video-sync=display-resample

I can't reproduce this time, both of your logs set vf=d3d11vpp=scale=2:scaling-mode=nvidia:format=nv12. Can you produce a log file without that set?

Try this one: output.txt

Hmm can you try this build https://github.com/shinchiro/mpv-winbuild-cmake/releases/tag/20240901 ?

I think the msvc CI builds just don't have av1 swdec. Can you try downloading mpv-x86_64-w64-mingw32 instead?

Ah nice, thanks! It works!
