current FFMPEG that is compiled with nlmeans_vulkan??

[RogerTango]

Ive downloaded several full bins for Win64 and ran -filters and none so far show is supports nlmeans_vulkan....


however....

It shows it in the filter base of ffmpeg... at...
https://ffmpeg.org/ffmpeg-filters.html#nlmeans_005fvulkan

So, now I am confused...

Thoughts/experiences??

Check if your ffmpeg build was compiled with vulkan enabled - at some point you may need to build such ffmpeg with vulkan enabled by yourself...

[LigH.de]

The media-autobuild suite may help you doing that using a very configurable and self-updating MSYS2/MinGW environment.

There is just a chance that some developer just messed up the sources of a linked module to not build properly at the moment, so the process might fail from time to time ... until they fix it or the suite implements a temporary workaround, e.g. falling back to an older source snapshot which still worked.

Try at https://www.gyan.dev/ffmpeg/builds/ - seem full release is build with vulkan support

Thanks! I *finally* got it to work with vob source (720x480) using:

-init_hw_device opencl=gpu:0.0 -filter_hw_device gpu -filter:v "hwupload,nlmeans_opencl,hwdownload,format=yuv420p"

However, I am only getting 14fps encode with GTX 1050TI. Using HandbrakeCLI's NLMeans, I was encoding at 200fps (both with NVENC_HEVC)

I need to dig into this more, but Ill stick with HB until I can figure out a better way to get FFMPEG to work.

Thanks again!

After doing some more digging, I added the arguments to the filter as suggested at:

https://forum.videohelp.com/threads/398880-Optimising-Performance-of-NLMeans-in-FFmpeg

and am now getting 280fps encode...

Ive got some experimenting to do!!!

Thanks for everyone's help, esp. pandy!
