how to install ffmpeg and add it to path

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. ldd which ffmpeg find /usr/local/lib/ Let’s add the directory on the ldconfig cache. To fix that issue we need to add the path /usr/local/lib shared libraries ldconfig cache. Time command outputs with GPU used: realĐm28.494sįfmpeg speed up by 4.32x: frame= 7320 fps=259 q=31.0 Lsize= 50294kB time=00:02:02.03 bitrate=3376.2kbits/s speed=4.32x 1) We need to ensure that some codecs and FFmpeg itself are not installed in our system.

Time ~/ffmpeg/ffmpeg -hwaccel cuda -y -i /tmp/input.mkv /tmp/out.mp4 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
