Reproduction Steps

playing a 1080i h.264 video, with no scripts or shaders loaded, using the following config

hwdec=vulkan
vo=gpu-next
gpu-context=winvk

trying to use video filters like pullup + dejudder doesn't work, is like the filters weren't there at all, commenting the winvk line makes the filters work

Expected Behavior

filters work on winvk

Actual Behavior

filters don't work on winvk

Log File

output.txt

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.

--hwdec=vulkan-copy

You can't insert CPU filters into a video without copy-back.

https://mpv.io/manual/master/#options-hwdec

auto-copy selects only modes that copy the video data back to system memory after decoding. This selects modes like vaapi-copy (and so on). If none of these work, hardware decoding is disabled. This mode is usually guaranteed to incur no additional quality loss compared to software decoding (assuming modern codecs and an error free video stream), and will allow CPU processing with video filters. This mode works with all video filters and VOs.
