https://ffmpeg.org/ffmpeg-filters.html#toc-Examples-89

it says

====
Run this filter on the CPU, on systems with Mesa installed (and with the
most expensive options disabled):

ffmpeg ... -init_hw_device vulkan:llvmpipe ... -vf
libplacebo=upscaler=none:downscaler=none:peak_detect=false

====

but to be honest it does not work that fast in this mode. But may be on
much faster cpu ot will work better?
