And finally, ffmpeg configured and complied with -enable-cuda-nvcc option.In short, to enable support for GPU-assisted encoding with an NVIDIA GPU for ffmpeg, you need: Please see NVIDIA documentations and ffmpeg wiki page for further information. You learned how to install FFmpeg with NVIDIA GPU acceleration hardware support on Debian or Ubuntu Linux to speed up encoding with the ffmpeg command. Make sure you read the following man pages using the man command: Mine is a consumer-grade GPU, but no doubt data center or professional-grade NVIDIA GPU gives even better performance. If you are converting M4V to MP4 on Mac, press on Space and input clear to clear the Terminal. If you are converting M4V to MP4 on Windows, press Windows Key and R, enter CMD to launch up the Command Prompt in administrator mode, input ffmpeg-version and tap Enter. Time ~/ffmpeg/ffmpeg -hwaccel cuda -y -i /tmp/input.mkv /tmp/out.mp4 Enter brew install ffmpeg on the Terminal to install FFmpeg on Mac.
Time command outputs with CPU used: realđm40.678sĪlso note down the speed: frame= 7320 fps= 73 q=-1.0 Lsize= 58306kB time=00:02:02.03 bitrate=3914.0kbits/s speed=1.22xĪnd now same file with NVIDIA GPU acceleration (note the path, I am calling the compiled version):
Time /bin/ffmpeg -y -i /tmp/input.mkv /tmp/out.mp4 In this example, I am converting input.mkv to out.mp4 as follows without using GPU acceleration: Related: Top 7 Linux GPU Monitoring and Diagnostic Commands Line Tools Result
