I have a CPU 8 cores / 16 threads, but the final rendering uses only one core. I tried with mp4/h264-5; webm/VP9; mkv/h264-5 e Prores. A 45 min video takes 3h 30m. I tried adding the parameters "threads=15", "wpp" which should be active by default and "frame-threads=3"; but the result is the same. On average I do 15 fps. Using h264-5 with nvenc takes 1h20m; but the CPU still uses only one core. On average I make 115 fps. Using an external engine (handbrake, which uses ffmpeg) you can use both the Cpu and the GPU; the rendering will take 10m! (but with lower quality). Since I'm compiling CinGG (note: all threads are used for compiling), maybe I need to enable some flags or something like that? Are there any customizations to do? Or should I set something in the operating system? Another question: How do you configure the render farm to use only the local CPU cores?
