It describes the process to use the FFmpeg libraries on Ubuntu 16.04. This article provides important updates to the 2012 article.

A 2012 article by Petter Larsson began exploring how to use the FFmpeg libav* APIs and Media SDK APIs together in the same application.

The Intel ® FFmpeg plug-in project is a fork of FFmpeg which attempts to explore additional options to improve performance for Intel hardware within the FFmpeg framework.

FFmpeg supports the default Media SDK plugin and this article describes the transcoding performance of the plugin, the detailed installation and validation guide is here.

FFmpeg wrappers for lower level APIs "underneath" Media SDK in the stack: libva (Linux) and DXVA (Windows).Intel ® provides several ways for you to use hardware acceleration in FFmpeg. To get the best of both worlds – full performance and access to the full range of capabilities in FFmpeg – a hybrid approach is recommended. However, the tradeoff for this ease of use is that performance is still left on the table. Various forms of these wrappers have existed for many years, and they provide important ease of use benefits compared to writing encode/decode code directly with the Media SDK API. It is straightforward to extend FFmpeg with wrappers for Intel ® HW acceleration. Because of this it has a very wide range of functionality beyond just codecs: muxing and demuxing(splitting), audio, network streaming, and more. FFmpeg is one of the most popular media frameworks. However, there is a big limitation: the Media SDK API only processes video elementary streams. Media SDK and Media Server Studio provide great performance with an API designed around delivering full hardware capabilities that is portable between OSes. All you have to do is tell APT to grab and install the program from the default Ubuntu software repo.įire up a terminal, update the APT cache, and install FFmpeg.Intel ® GPUs contain fixed function hardware to accelerate video encode, decode, and frame processing, which can now be used with a variety of interfaces. This is the default method for installing FFmpeg. However, this method is a bit complex and it is recommended not to follow this method unless you have a specific reason to do so. It is also possible to compile and install FFmpeg from the source. Depending on your needs, you should choose the most appropriate method for you.

There are two official ways of installing FFmpeg on Ubuntu: from the Ubuntu repo (v7.x) and from the snap (v4.x). This guide will show you how to install and use FFmpeg in Ubuntu 20.04. FFmpeg can convert audio and video into different formats, resize and configure sample rates, and much more. This program supports a wide range of audio and video libraries, including libavformat, libavutil, libavcodec, etc. It is an open-source CLI tool that is available for all the major platforms. FFmpeg is a powerful tool used for transcoding multimedia files.
