Description
Summary of the bug:
How to reproduce:
ffmpeg -v verbose -init_hw_device vulkan=vul -filter_hw_device vul -i input1080p.264 -vf "hwupload=extra_hw_frames=16,scale_vulkan=1920:1080,hwdownload,format=yuv420p" -f rawvideo output.yuv built on ffmpeg master GPU: 2080Ti
This command reports a segmentation fault at https://github.com/FFmpeg/FFmpeg/blob/1f58503013720700a5adfd72c708e6275aefc165/libavfilter/vulkan.c#L1217
I think the problem is that when queue_count is greater than 1, pl->descriptor_sets_num will be greater than pl->desc_layout and vkAllocateDescriptorSets will cause error.
