Description
Summary of the bug: ffmpeg creates very corrupted video when encoding with vulkan on both ANV (Intel) & Nvidia & AMD.
How to reproduce:
% ffmpeg -init_hw_device vulkan=vkdev:0 -filter_hw_device vkdev -f lavfi -i testsrc -t 10 -filter:v "format=nv12,hwupload" -an -c:v h264_vulkan out.mp4 ffmpeg version N-117737-g10c02deccb Copyright (c) 2000-2024 the FFmpeg developers built with gcc 14.2.1 (GCC) 20240910
If I add -g 1 the output video is not corrupted. Tested with Mesa git 0a81434adf44eaeeb246a57e2f00a00a01e0e67a & nvidia drivers 565.57.01. For ANV, note that you need to set ANV_VIDEO_ENCODE=1 in the environment.
I don't personally have an AMD device to test on, but I had someone test for me and it was also very corrupted.
