Other Information

- Windows version: Microsoft Windows [版本 10.0.26200.8246]
- GPU model, driver and version: Intel(R) Arc(TM) B580 Graphics 101.8735
- Source of mpv: mpv v0.40.0-291-g5faec4e6a
- Latest known working version:  mpv v0.40.0-279-g07572dc83
- Issue started after the following happened: mpv.exe --gpu-debug --log-file=output.txt --hwdec=vulkan --gpu-api=vulkan --gpu-context=winvk

Reproduction Steps

Use any version newer than mpv v0.40.0-279-g07572dc83(20250817), for example:mpv v0.40.0-291-g5faec4e6a（20250824）
mpv.exe --gpu-debug --log-file=output.txt --hwdec=vulkan --gpu-api=vulkan --gpu-context=winvk

Expected Behavior

After the MPV is running, the LOGO in the middle of the window does not appear. It is unable to play videos using Vulkan.

Actual Behavior

[ 0.075][e][vo/gpu-next/libplacebo] vk->CreateDevice(vk->physd, &dinfo, PL_VK_ALLOC, &vk->dev): VK_ERROR_FEATURE_NOT_PRESENT (../../../../../src_packages/libplacebo/src/vulkan/context.c:1314)

Sample Files

No response

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

• I tested and confirmed that the issue exists with the latest release version or newer.
• 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.

The implication is a missing feature in the driver. Intel drivers on windows would not surprise me if they had some theoretically impossible missing features despite the Vulkan version and extensions they claim to support.

Can you rerun with --gpu-debug. We need to see which feature is being reported as not present.

Thanks.

mpv.exe --gpu-debug --log-file=output.txt --hwdec=vulkan --gpu-api=vulkan --gpu-context=winvk

This is the command I use to extract logs, and all previously submitted logs were generated in this way. Could you please advise how I should modify it to obtain the content you need?

[philipl]

Hmm. Maybe the validation layer doesn't do anything this early in initialization. @haasn @kasper93 is there a way to make libplacebo print the missing feature?

Since I deleted all downloaded files after yesterday's testing, this log was generated using mpvnet. If this is not suitable, I will download the official mpv again and redo it.

mpvnet.exe --no-config --msg-time --gpu-debug --log-file=mpv_vulkan_full.log --msg-level=all=trace,vulkan=trace,libplacebo=trace,ffmpeg=debug,vo=debug,hwdec=debug --hwdec=vulkan --gpu-api=vulkan --gpu-context=winvk --vo=gpu-next
