DivX is often a manufacturer of products produced by DivX, Inc. (formerly DivXNetworks, Inc.), for example the DivX Codec which has gain popularity automobile capability to compress lengthy video segments into smaller portions and relatively high visual quality. DivX family includes: DivX Plus Player, DivX PlusWeb Player, DivX PlusCodec Pack, and DivX Plus Converter, etc. For you are two DivX codecs: the normal MPEG-4 Part 2 DivX codec and also the H.264/MPEG-4 AVC DivX plus HD codec. It really is among the many codecs often related to "ripping", whereby video and audio multimedia is moved to an arduous disk and transcoded.
DivX 6 expanded the scope of DivX from including simply a codec and a player by having an optional media container format called "DivX Media Format" ("DMF") (which has a .divx extension) that has support for an additional DVD-Video and VOB container like features. This media container format is employed for your MPEG-4 Part 2 codec.
DivX Media Format (DMF) features:
Interactive video menus
Multiple subtitles (XSUB)
Multiple audio tracks
Multiple video streams (for special features like bonus/extra content, just like on DVD-Video movies)
Other metadata (XTAG)
Partial backwards compatibility with AVI
This new "DivX Media Format" also had a "DivX Ultra Certified" profile, and many types of "Ultra" certified players must support all "DivX Media Format" features. While video encoded using the DivX codec is surely an MPEG-4 video stream, the DivX Media Format is analogous to media container formats like Apple's QuickTime. In much the same method that media formats for instance DVD specify MPEG-2 video began this morning their specification, the DivX Media Format specifies MPEG-4-compatible video as an element of its specification. However, in spite of the utilisation of the ".divx" extension, this format is definitely an extension for the AVI extendable. Particularly of including multiple audio as well as subtitle tracks involve storing the info in RIFF headers and also other such AVI hacks which are recognized for many years, in ways that even VirtualDubMod supports them. DivX, Inc. did this on purpose to keep at the very least partial backwards compatibility with AVI, making sure that players that will not offer the latest features accessible to the .divx container format (like interactive menus, chapter points and XSUB subtitles) can at any rate play that primary video stream (usually the main movie when the DMF file contains multiple video streams like special features like bonus materials). Certainly, the DivX codec and tools like Dr. DivX still support the traditional way of creating standard AVI files.
