Reproduction Steps

Play any high resolution video with vulkan hwdec.

Expected Behavior

No framedrops.

Actual Behavior

Framedrops.

Log File

Can't get log with --gpu-debug because of validation errors.

The issue only happens on drivers that doesn't use additional images for DPB - VK_VIDEO_DECODE_CAPABILITY_DPB_AND_OUTPUT_COINCIDE_BIT_KHR.

Decoding is stalled by waiting on rendering current frame, if the current frame is used as reference for decoding next frame.

Using -vf scale_vulkan to force copy workarounds the issue. No issue with VAAPI

Sample Files

No response

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

• I tested with the latest mpv version to validate that the issue is not already fixed.
• 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.
