Ffmpeg mac using cpu2/18/2023 Is it possible for ffmpeg to use the GPU to encode instead of the CPU. ![]() I am assuming the dedicated GPU would be faster at encoding h264 video. You can see this in action below (the machine is an i7 6700K with 16GB of memory), with the CPU's logical cores seeming to hover around 50-60 usage while the output speed at the bottom is well under 1x. When I encode h264 video on my Macbook Pro with ffmpeg it uses the intel CPU and not the dedicated AMD Radeon Pro 560 GPU. support on linux with Intel > 9th gen CPU My old Mac 3,1 tower is finally. ![]() For best quality, Id recommend rendering in ProRes. Use Intel QuickSync with ffmpeg to have hardware accelerated video decoding. Stream #0:1(ger): Audio: dts (DTS), 48000 Hz, 5.1(side), s16, 1536 kb/s (default) What's confusing me is that according to htop, ffmpeg isn't using anywhere near the max amount of available CPU. A high cpu usage normally is desired, since it means rendering will be as fast as it could possibly be. ![]() ![]() I’ve seen suggestions to set the -threads option to 1.5 the number of cores, which doesn’t make any sense.

While ffmpeg has multithreading capability, getting the best performance on multi-core systems calls for something more than just playing with the -threads option.
