I have yet to get my system ffmpeg vulkan video transcoding to work on my machines, while benchmarking works. Therefore I hope get verified if my code line is correct, and how to fix possible syntax errors.

=====================
ah, syntax was slightly different, you apparently need to "link" vulcan decode and filtering via common naming?
I am afraid I don't understand how to "link vulkan decode and filtering via common naming?" Could you possibly give me one or two examples to test with my code line?
My line fails in similar way:
