Because I tend to track this issue https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/19232 see latest notes there (you need llvm 15.0.4 - yeah, in this case 0.0.1 version matters) and mesa git + some merge requests manually merged, but results relatively promising - darktable starts and enjoy some 2x speedup (on Power CPU, no less!), Lux render also starts and works. Ffmpeg I guess not tested yet :) for me ffmpeg -filters | grep opencl shows ... avgblur_opencl V->V Apply average blur filter ... boxblur_opencl V->V Apply boxblur filter to input video ... colorkey_opencl V->V Turns a certain color into transparency. Operates on RGB colors. ... convolution_opencl V->V Apply convolution mask to input video ... deshake_opencl V->V Feature-point based video stabilization filter ... dilation_opencl V->V Apply dilation effect ... erosion_opencl V->V Apply erosion effect ... nlmeans_opencl V->V Non-local means denoiser through OpenCL ... overlay_opencl VV->V Overlay one video on top of another ... pad_opencl V->V Pad the input video. ... prewitt_opencl V->V Apply prewitt operator ... program_opencl |->V Filter video using an OpenCL program ... roberts_opencl V->V Apply roberts operator ... sobel_opencl V->V Apply sobel operator ... tonemap_opencl V->V Perform HDR to SDR conversion with tonemapping. ... transpose_opencl V->V Transpose input video ... unsharp_opencl V->V Apply unsharp mask to input video ... xfade_opencl VV->V Cross fade one video with another video. ... openclsrc |->V Generate video using an OpenCL program for tonemapping on OpenCL this line was suggested (on Nvidia) - see below. https://superuser.com/questions/1549479/ffmpeg-4k-hdr-to-1080p-sdr-hardware-... so I guess we can use it as example for trying on Radeons (comment about OpenCL 1.2 needed still apply, but rusticl exposes 3.0 :-) ) there is also AUR package, but not sure if it tracks right branch from Karol Herbst (developer) repo .. https://aur.archlinux.org/packages/mesa-rusticl-git I personally look at https://gitlab.freedesktop.org/karolherbst/mesa/-/commits/rusticl/wip_nv/ note enabling this also require some environment flags to be set. ffmpeg -vsync 0 -hwaccel cuda \ -init_hw_device opencl=ocl \ -filter_hw_device ocl -extra_hw_frames 3 \ -threads 16 -c:v hevc_cuvid \ -resize 1920x1080 -i INPUT \ -vf "format=p010,hwupload,tonemap_opencl=tonemap=mobius:param=0.01:desat=0:r=tv:p=bt709:t=bt709:m=bt709:format=nv12,hwdownload,format=nv12" \ -c:a copy -c:s copy \ -c:v libx264 -max_muxing_queue_size 9999 OUTPUT
