hwcontext_vulkan : rewrite upload/download
18 juillet 2024, par Lynnehwcontext_vulkan : rewrite upload/download

handles falling back to buffer-based uploads if host-mapping fails.Roundtrip performance difference :
ffmpeg -init_hw_device "vulkan=vk:0,debug=0,disable_multiplane=1" -f lavfi \i color=red:s=3840x2160 -vf hwupload,hwdownload,format=yuv420p -f null -
