'''FFmpeg''' is a [[free and open-source software]] project consisting of a suite of [[Library (computing)|libraries]] and [[Computer program|programs]] for handling video, audio, and other [[multimedia]] files and streams. At its core is the [[Command-line interface|command-line]] <code>ffmpeg</code> tool itself, designed for processing video and audio files. It is widely used for format [[transcoding]], basic editing (trimming and [[concatenation]]), [[Video scaler|video scaling]], video [[post-production]] effects, and standards compliance ([[Society of Motion Picture and Television Engineers|SMPTE]], [[International Telecommunication Union|ITU]]).
FFmpeg also includes other tools: <code>ffplay</code>, a simple media player, and <code>ffprobe</code>, 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">{{cite web|url=https://www.ffmpeg.org/doxygen/2.2/group__libavf.html|title=FFmpeg: Lavf: I/O and Muxing/Demuxing Library|work=ffmpeg.org|access-date=21 October 2016|archive-date=3 December 2016|archive-url=https://web.archive.org/web/20161203035541/http://ffmpeg.org/doxygen/2.2/group__libavf.html|url-status=live}}</ref> an audio/video [[Container format (computing)|container]] [[multiplexing|mux and demux]] library, and libavfilter, a library for enhancing and editing filters through a [[GStreamer]]-like filtergraph.<ref>{{Cite web|title=Libavfilter Documentation|url=https://ffmpeg.org/libavfilter.html|access-date=2021-10-07|website=ffmpeg.org|archive-date=2021-10-07|archive-url=https://web.archive.org/web/20211007032443/https://ffmpeg.org/libavfilter.html|url-status=live}}</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 media player|VLC]], and has been included in core processing for [[YouTube]] and [[Bilibili]].<ref>{{Citation|title=ijkplayer|date=2021-10-05|url=https://github.com/bilibili/ijkplayer|publisher=bilibili|access-date=2021-10-05|archive-date=2021-10-05|archive-url=https://web.archive.org/web/20211005224814/https://github.com/bilibili/ijkplayer|url-status=live}}</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.

== History ==
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">{{Cite web|url = https://ffmpeg.org/pipermail/ffmpeg-devel/2015-July/176489.html|title = [FFmpeg-devel] FFmpegs future and resigning as leader|access-date = 2015-09-22|first = Michael|last = Niedermayer| date=31 July 2015 |archive-date = 2015-08-15|archive-url = https://web.archive.org/web/20150815230313/https://ffmpeg.org/pipermail/ffmpeg-devel/2015-July/176489.html|url-status = live}}</ref> Some FFmpeg developers were also part of the [[MPlayer]] project.
The name of the project is inspired by the [[Moving Picture Experts Group|MPEG]] video standards group, together with "FF" for "fast forward", so FFmpeg stands for "Fast Forward Moving Picture Experts Group".<ref>{{cite web|last=Bellard|first=Fabrice|author-link=Fabrice Bellard|date=18 February 2006|title=FFmpeg naming and logo|url=https://ffmpeg.org/pipermail/ffmpeg-devel/2006-February/010315.html|access-date=24 December 2011|work=FFmpeg developer mailing list|publisher=FFmpeg website|archive-date=26 April 2012|archive-url=https://web.archive.org/web/20120426071311/http://ffmpeg.org/pipermail/ffmpeg-devel/2006-February/010315.html|url-status=live}}</ref> The logo represents a [[zigzag]] scan pattern that shows how MPEG video codecs handle [[entropy encoding]].<ref>{{cite web|last=Carlsen|first=Steve|date=1992-06-03|title=TIFF 6.0 specification|url=ftp://ftp.sgi.com/graphics/tiff/TIFF6.ps|access-date=2016-08-14|publisher=[[Aldus Corporation]]|page=98|format=PS|quote=Zig-Zag Scan}}{{dead link|date=May 2020|bot=medic}}{{cbignore|bot=medic}} [http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf Alt URL] {{Webarchive|url=https://web.archive.org/web/20120703095221/http://partners.adobe.com/public/developer/en/tiff/TIFF6.pdf |date=2012-07-03 }}</ref>
On March 13, 2011, a group of FFmpeg developers decided to fork the project under the name [[Libav]].<ref>{{citation|title=Libav project site|url=http://www.libav.org/|access-date=2012-01-04|archive-date=2012-01-03|archive-url=https://web.archive.org/web/20120103091848/http://libav.org/|url-status=live}}</ref><ref>{{citation|author=Ronald S.

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]] [[Git]] [[version control system]].<ref name="release_policy">{{cite web|url=https://ffmpeg.org/download.html#releases|title=ffmpeg.org/download.html#releases|publisher=ffmpeg.org|access-date=2015-04-27|archive-date=2011-10-06|archive-url=https://web.archive.org/web/20111006131811/http://www.ffmpeg.org/download.html#releases|url-status=live}}</ref>
=== Codec history ===
Two [[video coding format]]s with corresponding codecs and one [[digital container format|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">{{cite web

== Components ==
=== Command-line tools ===
* ''ffmpeg'' is a command-line tool that converts audio or video formats. It can also capture and encode in real-time from various hardware and software sources<ref>[[:commons:File:Gentoo-portage-installing-and-using-of-equery.webm|This video of Linux desktop (X11) was captured by ffmpeg and encoded in realtime]]{{Circular reference|date=March 2024}}</ref> such as a TV capture card.
* ''ffplay'' is a simple media player utilizing [[Simple DirectMedia Layer|SDL]] and the FFmpeg libraries.
* ''ffprobe'' is a command-line tool to display media information (text, [[Comma-separated values|CSV]], [[XML]], [[JSON]]), see also [[MediaInfo]].
=== Libraries ===
* ''libswresample'' is a library containing audio [[Resampling (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, [[Lempel–Ziv–Oberhumer|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 [[Color space|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 hardware ==
=== CPUs ===
FFmpeg encompasses software implementations of video and audio compressing and decompressing algorithms. These can be compiled and run on diverse instruction sets.
Many widespread [[instruction set]]s are supported by FFmpeg, including [[x86]] ([[IA-32]] and [[x86-64]]), PPC ([[PowerPC]]), [[ARM architecture family|ARM]], [[DEC Alpha]], [[SPARC]], and [[MIPS architecture|MIPS]].<ref>{{cite web |url=http://fate.multimedia.cx/ |title=FFmpeg Automated Testing Environment |publisher=Fate.multimedia.cx |access-date=2012-01-04 |archive-date=2016-04-10 |archive-url=https://web.archive.org/web/20160410165839/http://fate.multimedia.cx/ |url-status=live }}</ref>
=== Special purpose hardware ===
There are a variety of [[Application-specific integrated circuit|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>{{cite web |url=https://trac.ffmpeg.org/wiki/HWAccelIntro |title=FFmpeg Hardware Acceleration |publisher=ffmpeg.org Wiki |access-date=2016-11-12 |archive-date=2016-12-04 |archive-url=https://web.archive.org/web/20161204005157/http://trac.ffmpeg.org/wiki/HWAccelIntro |url-status=live }}</ref>

== Supported codecs and formats ==
=== Image formats ===
{{Technical|date=April 2023|section}}
FFmpeg supports many common and some uncommon image formats.
The {{anchor|PGMYUV}} '''PGMYUV''' image format is a homebrew variant of the binary (P5) PGM [[Netpbm format]]. FFmpeg also supports 16-bit depths of the PGM and PPM formats, and the binary (P7) [[Netpbm#PAM graphics format|PAM]] format with or without alpha channel, depth 8 bit or 16 bit for <code>pix_fmts</code> ''monob, gray, gray16be, rgb24, rgb48be, ya8, rgba, rgb64be''.
=== Supported formats ===
{{Further|libavcodec}}{{More citations needed section|date=July 2022}}
In addition to [[FFV1]] and Snow formats, which were created and developed from within FFmpeg, the project also supports the following formats:
