#9353: Vulkan filter cannot work on the latest mesa on Intel platform
-------------------------------------+-------------------------------------
Reporter: wenbin,chen | Type: defect

Summary of the bug:
How to reproduce:
{{{
ffmpeg -v verbose -init_hw_device vulkan=vul:2,linear_images=1
-filter_hw_device vul -i input1080p.mp4 -vf
"hwupload=extra_hw_frames=16,scale_vulkan=1920:1080,hwdownload,format=yuv420p"
-f rawvideo output.yuv
built on ffmpeg-master and mesa-21.2
Intel platform.
}}}
This command can work on mesa-20.1 which is installed through apt on
Ubuntu, but failed on latest mesa-21.2.
I found that a commit in mesa (a193060221c4df123e26a562949cae5df3e73cde)
causes this problem.
