DivX

 

DivX is a series of products that created by DivX, Inc. DivX Codec, for instance, became popular due to its ability to compress lengthy video segments into small sizes while maintaining relatively high visual quality.

 

DivX Codecs

There are two DivX codecs; the regular MPEG-4 Part 2 Divx codec and the H.264/MPEG-4 AVI DivX Plus HD codec. They are commonly associated with "ripping", whereby audio and video multimedia are transfered to a hard disk and transcoded.


Official Decoders and Encoders

Official decoders and encoders are provided for Microsoft Windows, Mac OS and BeOS, with unmaintained older releases for the Amiga and Linux. In addition, FFmpeg can decode 3ivx encoded video.

 

DivX formats

DMF | DivX Media Format

DivX Media Format
Filename Extension .divx
Tyoe code DIVX
Developed By DivX,Inc.
Type of format media container
Contained for MPEG-4 Part 2–compliant video
Extended from AVI

DivX 6 expanded the scope of DivX from including just a codec and a player by adding an optional media container format called "DivX Media Format" ("DMF")[12] (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.


DivX Media Format (DMF) features:

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 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 backwards 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.


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 video bitstream, AAC surround sound audio, and a number of XML-based attachments defining chapters, subtitles and meta data.[13] This media container format is used for the H.264/MPEG-4 AVC codec.


DivX profiles

DivX has defined profiles which are subsets of MPEG-4/AVI and H.264/Matroska standards. 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. Hence 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.


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. DivX, Inc. has 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
