How to install FFmpeg with NVIDIA GPU acceleration on Linux

To install FFmpeg with NVIDIA GPU acceleration on Linux, you can use the following steps:

1. Install the NVIDIA drivers:
   Follow the instructions at https://docs.nvidia.com/cuda/cuda-installation-guide-linux/index.html to install the NVIDIA drivers on your Linux system. This is required to enable GPU acceleration.

2. Install the dependencies for FFmpeg:
   sudo apt-get install build-essential nasm yasm pkg-config libtool libx264-dev libx265-dev libnuma-dev libvpx-dev libfdk-aac-dev libmp3lame-dev libopus-dev
   This installs the required packages for building FFmpeg.

3. Download the FFmpeg source code:
   wget https://ffmpeg.org/releases/ffmpeg-4.4.1.tar.bz2
tar xvf ffmpeg-4.4.1.tar.bz2
   This downloads and extracts the FFmpeg source code to a directory called ffmpeg-4.4.1.

4. Change to the FFmpeg directory:
   cd ffmpeg-4.4.1

5. Configure FFmpeg:
   ./configure --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp
   This enables GPU acceleration and various other FFmpeg features.

6. Build and install FFmpeg:
   make
sudo make install
   This builds and installs FFmpeg on your system.
