Sigma Designs was contacted and confirmed that a programmer had based REALmagic on Xvid, but assured that all GPL code would be replaced to avoid copyright infringement. Before long, people testing this new codec found that it contained considerable portions of Xvid code.

In July 2002, Sigma Designs released an MPEG-4 video codec called the REALmagic MPEG-4 Video Codec. However, the legal usage of Xvid may still be restricted by local laws. With the 1.0.x releases, a GNU GPL v2 license is used with no explicit geographical restriction.

For this reason, Xvid 0.9.x versions were not licensed in countries where these software patents are recognized. Since then, all the OpenDivX code has been replaced and Xvid has been published under the GNU General Public License.Īs an implementation of MPEG-4 Part 2, Xvid uses many patented technologies. Soon after, DARC released a beta version of their closed-source commercial DivX 4 codec, which was based on encore2, saying that 'what the community really wants is a Winamp, not a Linux.' It was after this that a fork of OpenDivX was created, using the latest version of encore2 that was downloaded before it was removed. In July 2001, developers started complaining about a lack of activity in the project the last CVS commit was several months old, bugfixes were being ignored, and promised documentation had not been written.

The explanation given by Sparky was 'We (our bosses) decided that we are not ready to have it in public yet.' This was updated several times before, in April, it was removed from CVS without warning. In early 2001, DARC member Sparky wrote an improved version of the encoding core called encore2. The source code, however, was placed under a restrictive license and only members of the DivX Advanced Research Centre (DARC) had write access to the project's CVS. OpenDivX was an open-source MPEG-4 video codec based on a stripped-down version of the MoMuSys reference MPEG-4 encoder. In January 2001, DivXNetworks founded OpenDivX as part of Project Mayo which was intended to be a home for open source multimedia projects. This also means that unlike the DivX codec, which is only available for a limited number of platforms, Xvid can be used on all platforms and operating systems for which the source code can be compiled. In contrast with the DivX codec, which is proprietary software developed by DivX, Inc., Xvid is free software distributed under the terms of the GNU General Public License.

Xvid is a primary competitor of the DivX Pro Codec. It uses ASP features such as b-frames, global and quarter pixel motion compensation, lumi masking, trellis quantization, and H.263, MPEG and custom quantization matrices. Xvid (formerly ' XviD') is a video codec library following the MPEG-4 video coding standard, specifically MPEG-4 Part 2 Advanced Simple Profile (ASP).
