Using NVIDIA hardware acceleration in FFmpeg/libav requires the following steps
- Download and install the compatible driver from NVIDIA web site
- Download and install
ffnvcodec:git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git cd nv-codec-headers && sudo make install && cd - -
Download and install the CUDA Toolkit CUDA toolkit
For Linux Mint 19.3:
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/cuda-ubuntu1804.pin sudo mv cuda-ubuntu1804.pin /etc/apt/preferences.d/cuda-repository-pin-600 sudo apt-key adv --fetch-keys https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/7fa2af80.pub sudo add-apt-repository "deb https://developer.download.nvidia.com/compute/cuda/repos/ubuntu1804/x86_64/ /" sudo apt-get update sudo apt-get -y install cuda - Ensure that your PATH includes the bin directory where you installed the Toolkit
export PATH=/usr/local/cuda-10.2/bin${PATH:+:${PATH}} - Install
sudo apt install nasm yasm - Download the latest FFmpeg or libav source code, by cloning the corresponding GIT repositories
- FFmpeg: https://git.ffmpeg.org/ffmpeg.git
- Libav: https://github.com/libav/libav
- Use the following configure command (Use correct CUDA library path in config command below)
./configure --enable-cuda-nvcc --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp --extra-cflags=-I/usr/local/cuda/include --extra-ldflags=-L/usr/local/cuda/lib64 - Use the following command to compile:
make -j $(nproc) - Install
sudo make install
