At its core is the command-line ffmpeg tool itself, designed for processing video and audio files. It is widely used for format transcoding, basic editing (trimming and concatenation), video scaling, video post-production effects, and standards compliance (SMPTE, ITU).

FFmpeg also includes other tools: ffplay, a simple media player, and ffprobe, a command-line tool to display media information. Among included libraries are libavcodec, an audio/video codec library used by many commercial and free software products, libavformat (Lavf),<ref name="Lavf">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> an audio/video container mux and demux library, and libavfilter, a library for enhancing and editing filters through a GStreamer-like filtergraph.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

FFmpeg is part of the workflow of many other software projects, and its libraries are a core part of software media players such as VLC, and has been included in core processing for YouTube and Bilibili.<ref>Template:Citation</ref> Encoders and decoders for many audio and video file formats are included, making it highly useful for the transcoding of common and uncommon media files.

FFmpeg is published under the LGPL-2.1-or-later or GPL-2.0-or-later, depending on which options are enabled.<ref name="legal">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

HistoryEdit

The project was started by Fabrice Bellard<ref name="legal" /> (using the pseudonym "Gérard Lantau") in 2000, and was led by Michael Niedermayer from 2004 until 2015.<ref name=":0">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Some FFmpeg developers were also part of the MPlayer project.

The name of the project is inspired by the MPEG video standards group, together with "FF" for "fast forward", so FFmpeg stands for "Fast Forward Moving Picture Experts Group".<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The logo represents a zigzag scan pattern that shows how MPEG video codecs handle entropy encoding.<ref>Template:Cite FTP Alt URL Template:Webarchive</ref>

On March 13, 2011, a group of FFmpeg developers decided to fork the project under the name Libav.<ref>Template:Citation</ref><ref>Template:Citation</ref><ref>Template:Citation</ref> The group decided to fork the project due to a disagreement with the leadership of FFmpeg.Template:Clarify<ref>Template:Citation</ref><ref>Template:Citation</ref><ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> Despite an initial push in Debian and derived distributions, Libav was considered inferior to FFmpeg in both technical merit and popularity,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> prompting Debian and Gentoo to switch back to FFmpeg in 2015. Libav was declared abandoned in 2020.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

On January 10, 2014, two Google employees announced that over 1000 bugs had been fixed in FFmpeg during the previous two years by means of fuzz testing.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In January 2018, the ffserver command-line program – a long-time component of FFmpeg – was removed.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> The developers had previously deprecated the program citing high maintenance efforts due to its use of internal application programming interfaces.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

The project publishes a new release every three months on average. While release versions are available from the website for download, FFmpeg developers recommend that users compile the software from source using the latest build from their source code, using the Git version control system.<ref name="release_policy">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Codec historyEdit

Two video coding formats with corresponding codecs and one container format have been created within the FFmpeg project so far. The two video codecs are the lossless FFV1, and the lossless and lossy Snow codec. Development of Snow has stalled, while its bit-stream format has not been finalized yet, making it experimental since 2011. The multimedia container format called NUT is no longer being actively developed, but still maintained.<ref name="nut">{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In summer 2010, FFmpeg developers Fiona Glaser, Ronald Bultje, and David Conrad, announced the ffvp8 decoder. Through testing, they determined that ffvp8 was faster than Google's own libvpx decoder.<ref>Template:Citation</ref><ref>Template:Citation</ref> Starting with version 0.6, FFmpeg also supported WebM and VP8.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

In October 2013, a native VP9<ref name="LaunchpadVP9Decoder">Template:Cite news</ref> decoder and OpenHEVC, an open source High Efficiency Video Coding (HEVC) decoder, were added to FFmpeg.<ref name=FFmpegHEVCOctober2013Softpedia>Template:Cite news</ref> In 2016 the native AAC encoder was considered stable, removing support for the two external AAC encoders from VisualOn and FAAC.

ComponentsEdit

Command-line toolsEdit

LibrariesEdit

  • libswresample is a library containing audio resampling routines.
  • libavresample is a library containing audio resampling routines from the Libav project, similar to libswresample from ffmpeg.
  • libavcodec is a library containing all of the native FFmpeg audio/video encoders and decoders. Most codecs were developed from scratch to ensure best performance and high code reusability.
  • libavformat (Lavf)<ref name="Lavf" /> is a library containing demuxers and muxers for audio/video container formats.
  • libavutil is a helper library containing routines common to different parts of FFmpeg. This library includes hash functions, ciphers, LZO decompressor and Base64 encoder/decoder.
  • libpostproc is a library containing older H.263 based video postprocessing routines.
  • libswscale is a library containing video image scaling and colorspace/pixelformat conversion routines.
  • libavfilter is the substitute for vhook which allows the video/audio to be modified or examined (for debugging) between the decoder and the encoder. Filters have been ported from many projects including MPlayer and avisynth.
  • libavdevice is a library containing audio/video io through internal and external devices.

Supported hardwareEdit

CPUsEdit

FFmpeg encompasses software implementations of video and audio compressing and decompressing algorithms. These can be compiled and run on many different instruction sets, including x86 (IA-32 and x86-64), PPC (PowerPC), ARM, DEC Alpha, SPARC, and MIPS.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>

Special purpose hardwareEdit

There are a variety of application-specific integrated circuits (ASICs) for audio/video compression and decompression. These ASICs can partially or completely offload the computation from the host CPU. Instead of a complete implementation of an algorithm, only the API is required to use such an ASIC.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
