How To Install NVENC in Ubuntu: Step-by-Step Guide

Ubuntu 5

In this guide, we will walk you through a step-by-step process on how to install and compile NVENC in Ubuntu. NVENC, or NVIDIA Encoder, is a feature in Nvidia graphics cards that performs video encoding, offloading this compute-intensive task from the CPU.

Prerequisites

Before proceeding, ensure you have the following:

  • An Nvidia graphics card that supports NVENC. You can check the Nvidia official website for a list of supported graphics cards.
  • The latest Nvidia drivers installed. The latest version of nv-codec-headers corresponds to Video Codec SDK version 11.0.10 and requires Nvidia drivers version 455.28 or newer.

Step 1: Install the nv-codec-headers package

The first step is to install the nv-codec-headers package. Open a terminal and run the following commands:

sudo apt-get install make git
mkdir $HOME/nv-codec-headers_build && cd $HOME/nv-codec-headers_build
git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git
cd nv-codec-headers
make && sudo make install

Here’s what each command does:

  • sudo apt-get install make git installs the ‘make’ and ‘git’ packages, which are required to build the nv-codec-headers package.
  • mkdir $HOME/nv-codec-headers_build && cd $HOME/nv-codec-headers_build creates a new directory in your home folder called ‘nv-codec-headers_build’ and navigates into it.
  • git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git clones the nv-codec-headers repository from the official FFmpeg project.
  • cd nv-codec-headers navigates into the cloned repository.
  • make && sudo make install builds and installs the nv-codec-headers package.

Step 2: Compile FFmpeg

Next, we will compile FFmpeg. FFmpeg is a free and open-source software project that produces libraries and programs for handling multimedia data. You can use the guide provided by FFmpeg for compiling on Ubuntu, Debian, or Mint. You can find it here.

The nv-codec-headers will be automatically recognized during the compilation process, so no extra configuration options are needed.

Step 3: Testing

After compiling FFmpeg, you can test if NVENC is working properly by running the following command in the terminal:

ffmpeg -encoders 2>/dev/null | grep nvenc

This command lists all the encoders available in FFmpeg and filters for ‘nvenc’. If you see a list of encoders with ‘nvenc’ in their names, and you have a supported graphics card, then NVENC is successfully installed and ready to use.

Conclusion

Congratulations! You have successfully installed and compiled NVENC in Ubuntu. Now you can take advantage of the power of your Nvidia graphics card to perform video encoding tasks.

Remember, if you need to revert to an earlier version of nv-codec-headers, you can download and compile an earlier release from the official GitHub repository: here. Always ensure that your graphics driver supports the minimum CUDA API version required by nv-codec-headers to avoid any compatibility issues.
