My question is (quite) simple: how can I 'translate' above to FFmpeg+OpenCL language? I'm using integrated Intel HD Graphics 4600 and external AMD Radeon HD 8790M. I call it usually like this: ffmpeg -framerate 30 -i frame-%05d.png -preset ultrafast -tune film -c:v h264 -c:v libx264 -b:v 20M -pix_fmt yuv420p output.mp4

I use FFmpeg mainly to convert images sequences to movies - thousands of images in 2K-4K resolution. I also installed FFmpeg with OpenCL support from Snapcraft ( ): ffmpeg version n4.1 Copyright (c) 2000-2018 the FFmpeg developersīuilt with gcc 5.4.0 (Ubuntu 5.4.0-6ubuntu1~16.04.10) 20160609Ĭonfiguration: -prefix= -prefix=/usr -disable-debug -disable-doc -disable-static -enable-avisynth -enable-cuda -enable-cuvid -enable-libdrm -enable-ffplay -enable-gpl -enable-libass -enable-libfdk-aac -enable-libfontconfig -enable-libfreetype -enable-libmp3lame -enable-libopencore_amrnb -enable-libopencore_amrwb -enable-libopus -enable-libpulse -enable-sdl2 -enable-libspeex -enable-libtheora -enable-libtwolame -enable-libv4l2 -enable-libvorbis -enable-libvpx -enable-libx264 -enable-libx265 -enable-libxcb -enable-libxvid -enable-nonfree -enable-nvenc -enable-omx -enable-openal -enable-opencl -enable-runtime-cpudetect -enable-shared -enable-vaapi -enable-vdpau -enable-version3 -enable-xlib I installed it on my OS (Kubuntu 18.04.2 LTS) and confirmed it works. After many tests I see that fighting with this topic is hard, especially if I read something like that: Feature support varies – for more complex codecs with many different profiles, hardware decoders rarely implement all of them (for example, hardware decoders tend not to implement anything beyond YUV 4:2:0 at 8-bit depth for H.264) ( ).īut maybe I just started with wrong solution? Maybe OpenCL is what I need? So I'd like to ask if someone could help me with OpenCL. Recently I asked about GPU acceleration in FFmpeg using AMD Radeon ( AMD support for ffmpeg? Can't get my dedicated GPU to work).

Ubuntu install ffmpeg with libx264
