'''DivX''' is a family and [[brand]] of [[video codec]] products developed by [[DivX, Inc.|DivX, LLC]]. There are three DivX [[codec]]s: the original [[MPEG-4 Part 2]] DivX codec, the [[H.264/MPEG-4 AVC]] DivX Plus HD codec and the [[High Efficiency Video Coding]] DivX HEVC Ultra HD codec. The most recent version of the codec itself is version 6.9.2, which is several years old. New version numbers on the packages now reflect updates to the media player, converter, etc.

 }}</ref> The video codec, which was actually not MPEG-4 compliant, was extracted around 1998 by French hacker [[Jerome Rota]] (also known as Gej) at Montpellier. The Microsoft codec originally required that the compressed output be put in an [[Advanced Systems Format|ASF]] file. It was altered to allow other [[container format (digital)|containers]] such as [[Audio Video Interleave]] (AVI).<ref>{{cite web

Instead of re-encoding his portfolio, Rota and German hacker Max Morice decided to [[reverse engineering|reverse engineer]] the codec, which "took about a week".<ref name="napTrap">{{cite web

In early 2000, Jordan Greenhall recruited Rota to form a company (originally called DivXNetworks, Inc., renamed to DivX, Inc. in 2005) to develop an MPEG-4 codec, from scratch, that would still be backward-compatible with the Microsoft MPEG-4 Version 3 format. This effort resulted first in the release of the "OpenDivX" codec and source code on 15 January 2001. OpenDivX was hosted as an open-source project on the Project Mayo web site hosted at projectmayo.com<ref>{{cite web |url=http://www.projectmayo.com/ |archive-url=https://web.archive.org/web/20030320172758/http://www.projectmayo.com/ |archive-date=2003-03-20 |title=Project Mayo |date=20 March 2003 |access-date=19 January 2010}}</ref> (the name comes from "[[mayonnaise]]", because, according to Rota, DivX and mayonnaise are both "French and very hard to make."<ref name="napTrap" />). The company's internal developers and some external developers worked jointly on OpenDivX for the next several months, but the project eventually stagnated.

In early 2001, DivX employee "Sparky" wrote a new and improved version of the codec's encoding algorithm known as "encore2". This code was included in the OpenDivX public source repository for a brief time, but then was abruptly removed. The explanation from DivX at the time was that "the community really wants a [[Winamp]], not a [[Linux]]." It was at this point that the project [[fork (software)|forked]]. That summer, Rota left the French Riviera and moved to [[San Diego]] "with nothing but a pack of cigarettes"<ref name="divxCeo">{{cite web | title=DivX CEO on Video, YouTube, iPod | url=http://www.redherring.com/Home/20135 | access-date=8 December 2006 | url-status=dead | archive-url=https://web.archive.org/web/20080205094020/http://www.redherring.com/Home/20135 | archive-date=5 February 2008 }}</ref> where he and Greenhall founded what would eventually become DivX, Inc.<ref name="napTrap" />

DivX took the encore2 code and developed it into DivX 4.0, initially released in July 2001. Other developers who had participated in OpenDivX took encore2 and started a new project—[[Xvid]]—that started with the same encoding core. DivX, Inc. has since continued to develop the DivX codec, releasing DivX 5.0 in March 2002. By the release of version 5.2.1 on 8 September 2004, the DivX codec was substantially feature-complete. Changes since then have tended to focus on speed, and encouraging wider hardware player support, while the company has also focused its time on the formats and next generation codecs.

In February 2011, DivX was acquired by [[Rovi Corporation]], upon completion of its acquisition of [[Sonic Solutions]].<ref name="divxRovi">{{cite web | title=Digital Entertainment Provider Rovi Acquires Sonic Solutions | url=http://www.mediapost.com/publications/?fa=Articles.showArticle&art_aid=141928 | access-date=23 December 2010 | url-status=dead | archive-url=https://web.archive.org/web/20101227041547/http://www.mediapost.com/publications/?fa=Articles.showArticle&art_aid=141928 | archive-date=27 December 2010 }}</ref> In 2014, [[Blackstone Group]] and [[Parallax Capital]] acquired DivX from Rovi for $75 million.

DivX 6 expanded the scope of DivX from including just a codec and a player by adding an optional [[Container format (digital)|media container format]] called "DivX Media Format" ("DMF")<ref>{{cite web

}}</ref> (with a .divx extension) that includes support for the following [[DVD-Video]] and [[VOB]] container like features. This media container format is used for the [[MPEG-4 Part 2]] codec.

This new DivX Media Format also came with a "DivX Ultra Certified" profile, and all "Ultra" certified players must support all DivX Media Format features. While video encoded with the DivX codec is an MPEG-4 video stream, the DivX Media Format is analogous to media container formats such as Apple's QuickTime. In much the same way that media formats such as DVD specify MPEG-2 video as a part of their specification, the DivX Media Format specifies MPEG-4-compatible video as a part of its specification. However, despite the use of the ".divx" extension, this format is an extension to the AVI file format. The methods of including multiple audio and even subtitle tracks involve storing the data in [[RIFF (File format)|RIFF]] headers and other such AVI hacks which have been known for quite a while, such that even [[VirtualDubMod]] supports them. DivX, Inc. did this on purpose to keep at least partial [[backward compatibility]] with AVI, so that players that do not support the new features available to the .divx container format (like interactive menus, chapter points and XSUB subtitles) can at least play that primary video stream (usually the main movie if the DMF file contains multiple video streams like special features like bonus materials). Of course, the DivX codec and tools like [[Dr. DivX]] still support the traditional method of creating standard AVI files.

Since version 5.0 of DivX, the [[FourCC]] (identifying code) for the DivX MPEG-4 Part 2 codec is DX50.<ref>{{Cite web |url=http://www.fourcc.org/codecs.php#letter_d |title=Fourcc.org Online list of FourCC codes |access-date=14 October 2019 |archive-date=23 May 2009 |archive-url=https://web.archive.org/web/20090523080617/http://www.fourcc.org/codecs.php#letter_d |url-status=dead }}</ref> Previously it used DIVX.

===DivX Plus HD===
{{Main|DivX Plus HD}}
DivX Plus HD is a marketing name for a file type using the standard [[Matroska]] media container format (.mkv), rather than the proprietary DivX Media Format. DivX Plus HD files contain an [[H.264/MPEG-4 AVC|H.264]] video bitstream, [[Advanced Audio Coding|AAC]] surround sound audio, and a number of XML-based attachments defining chapters, subtitles and meta data.<ref>{{cite web

===DivX profiles===
{{Update|date=October 2010}}
DivX has defined profiles which are subsets of MPEG-4/AVI and H.264/Matroska standards.<ref name=techspecs>{{cite web|title=DivX-Profiles_Tech-Specs|website=DivX|url=http://www.divx.com/files/DivX-Profiles_Tech-Specs.pdf|access-date=3 May 2017|archive-url=https://web.archive.org/web/20170503180053/http://www.divx.com/files/DivX-Profiles_Tech-Specs.pdf|archive-date=3 May 2017|url-status=dead}}</ref> Because the grouping is a specific subset of what is in the standards, there are certification processes for each of the profiles that device manufacturers must follow. All DivX certified devices bearing a DivX logo will adhere to one of the profiles outlined in the table below as would any tools that support the DivX profiles.<ref>{{cite web | url=http://www.divx.com/en/electronics/solutions | title=DivX Profiles from divx.com}}</ref><ref>{{cite web | url=http://www.divx.com/en/partner/certified/ic | title=certified listing from divx.com | url-status=dead | archive-url=https://web.archive.org/web/20101202213931/http://www.divx.com/en/partner/certified/ic | archive-date=2010-12-02 }}</ref>

===DivX Video on Demand===
DivX Video on Demand (DivX VOD) is DivX's version of [[digital rights management]] (DRM), which allows content copyright holders to control distribution.  In 2009, DivX, Inc. received format approval from major Hollywood studios including Sony, Paramount, and Lionsgate, which has allowed content retailers to sell protected videos that will play on current and previous generations of DivX certified devices.<ref>{{cite web |url=http://www.businessofcinema.com/news.php?newsid=13956 |title=DivX inks film distribution deal with Lionsgate & Paramount |date=4 August 2009 |access-date=1 April 2010 |website=Businessofcinema.com |url-status=dead |archive-url=https://web.archive.org/web/20110929155149/http://www.businessofcinema.com/news.php?newsid=13956 |archive-date=29 September 2011 }}</ref>  The terms of the contract are not known, so it is unknown if that approval is still in effect.{{Update inline|date=November 2020}}

''Dr. DivX OSS'' is capable of transcoding many video formats to DivX-encoded video.  The original closed-source Dr. DivX terminated at version 1.06 for DivX 5.21. That was the last version of DivX capable of running on [[Windows 9x]]. An open-source version has since been made, which supports DivX 6. ''Dr. DivX'' offers greatly expanded features over the free DivX Converter application, that was bundled with the codec from version 6 onwards.<ref>{{cite web|url=http://www.divx.com/divx/windows/converter/ |title=DivX Video Converter |publisher=DivX, Inc. |access-date=11 April 2010}}</ref> Dr. DivX is not compatible with DivX Plus HD.
