Other Information

- Windows version: Microsoft Windows [Version 10.0.26100.2605]
- GPU model, driver and version: Qualcomm(R) Adreno(TM) X1-85 GPU, DirectX 12 (FL 11.1) version 31.0.80.0
- Source of mpv: mpv-aarch64-20241226-git-d9eb9ed (https://github.com/shinchiro/mpv-winbuild-cmake/releases)
- Latest known working version: N/A
- Issue started after the following happened: Using the --vo=gpu-next video rendering backend

Reproduction Steps

The --vo=gpu-next backend driver causes mpv to crash when resizing its window during video playback on my Dell Inspiron 14 Plus 7441 featuring a Qualcomm(R) Adreno(TM) X1-85 GPU. This behaviour occurs during media playback and idle mode. However, this behaviour doesn't occur during the startup screen or when rendering content on other backends, like --vo=gpu and --vo=direct3d; it only occurs when the console parses the --vo=gpu-next parameter. Furthermore, the console doesn't print any error indicating why it crashes with the --vo=gpu-next backend driver enabled.

Incidentally, the console prints the following error messages when using --vo=gpu; however, these errors don't interfere with media playback.
[vo/gpu] Unrecognized/unavailable FORMAT name: 'rgba16f'!
[vo/gpu] Unrecognized command 'PARAM distance_coeff'!

Strangely enough, the console doesn't print these errors with the --vo=gpu-next video renderer enabled.

Expected Behavior

Seamless playback without crashing when resizing its associated window with the --vo=gpu-next parameter enabled.

Actual Behavior

mpv crashes when resizing its associated window with --vo=gpu-next enabled.

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.

Does gpu-context=winvk crash as well?
You need windbg and pdb to get meaningful crash backtrace.

[llyyr]

mpv cleanly exits in your logfile, I don't see any crashes.

Does gpu-context=winvk crash as well? You need windbg and pdb to get meaningful crash backtrace.

profile=gpu-hq
vo=gpu
priority=realtime
hwdec=d3d11va-copy
gpu-api=d3d11
gpu-context=winvk
vulkan-device=43510000-0600-0000-12c5-6000140012c5
vulkan-swap-mode=auto

No, --gpu-context=winvk doesn't make mpv crash with --hwdec=d3d11va-copy and --gpu-api=d3d11 enabled; its demuxer can play audio from media files, but it can't render any video footage.

pwsh output:
[vo/gpu] Failed initializing any suitable GPU context!
Error opening/initializing the selected video_out (--vo) device.

However, mpv refuses to execute when using --hwdec=vulkan-copy, --gpu-api=vulkan, and --gpu-context=winvk simultaneously.

profile=gpu-hq
vo=gpu
priority=realtime
hwdec=vulkan-copy

Incidentally, here's a windbg file for the following conf with --vo=gpu-next enabled:

gpu-api=d3d11
gpu-context=d3d11

windbg.txt

The following instruction shown at line 515 always appears before mpv crashes with --vo=gpu-next enabled. Line 512 shows that mpv crashes when the Access violation - code c0000005 (first chance) invalid memory address exception error message appears after adjusting the size of its window during video playback.

qcgpuarm64xcompilercore!LoadLLC+0x6d0e24:
00007ffb`2bbca3a4 39402268 ldrb w8,[x19,#8]

※Note: there's eight blank spaces between "ldrb" and "w8,[x19,#8]" for some reason. I've also tried installing shinchiro's x86_64 mpv executable instead of the native aarch64 one, but this behaviour persists.

mpv cleanly exits in your logfile, I don't see any crashes.

Yes, mpv cleanly exited after generating my logfile, but an Access violation - code c0000005 (first chance) invalid memory address exception error message appears whenever I adjust the size of its window during video playback when using --vo=gpu-next. When mpv's window becomes too big or small, its associated process freezes, crashes, and generates a dump file in the %LOCALAPPDATA%\mpv directory. My reply to Andarwinux's comment contains the relevant details regarding mpv's behaviour with --vo=gpu-next enabled during video playback.

I suspect that a graphics driver for my laptop's Qualcomm Adreno X1-85 GPU might be attributable to this behaviour. I've upgraded to the latest driver, Qualcomm-Adreno-X1-85-Graphics-Driver_PGKYF_WINARM64_31.0.80.0_A05.EXE (31.0.80.0, A05), which Dell released on December 16, 2024, but to no avail https://www.dell.com/support/home/en-ca/drivers/driversdetails?driverid=pgkyf&oscode=w11a6&productcode=inspiron-14-7441-laptop.
