Use libavfilter in vapoursynth?
I'm encoding on Apple Silicon Macs. However, KNLMEANSCL and libavfilter's nlmeans_opencl don't work correctly here for some reason. Luckily, libavfilter as a nlmeans_vulkan. Is it possible to use it inside vpys? Or I will have to port the code myself?

You have to port it.

CPU version of KNLMEANSCL https://github.com/AmusementClub/vs-nlm-ispc
I have no idea if can be compiled for mac or not. EDIT: I'm blind https://github.com/AmusementClub/vs-...me-ov-file#arm

If you are going to port somthing, is a somewhat general interface of libavfilters possible? So most of the FFmpeg's filters can be used...
(Talk about general interfaces I think vs-placebo, then I think perhaps you can use nlmeans shader) Last time I checked, vs-nlm-ispc got completely "smashed" by the opencl version in terms of speed, is it different in Apple Silicon chips? What performance is it that you would call it "very fast"? What is the "not work correctly" mean by the way? Is it crashing, or is it have corrupted output frames? |

Performance king would be vs-nlm-cuda, but I don't think cuda is supported on mac?

yeah cuda don't support mac. I'm now learning apple's metal, it's like 80% similar with cuda. But it's swift that made it hard to use in vapoursynth plugins.
