But does it actually work? ;)
I am glad you asked :) No, sorry - still no success with video transcoding using vulkan so far ...... At least I have not found a ffmpeg code line that works, conversion fails, similary for h264_vulkan and hevc_vulkan: ffmpeg -hide_banner -hwaccel vulkan -i hdv09_04.m2t -c:v h264_vulkan hdv09_04_h264_vulkan.mp4 .......... Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scale_0' Link 'Parsed_null_0.default' -> 'auto_scale_0.default': src: yuv420p dst: yuv420p [vf#0:0 @ 0x5640cf955040] Error reinitializing filters!

I think prores (not prores RAW) work exist in ffmpeg.git for now ....
