Xvid (formerly "XviD") is a video codec library following the MPEG-4 video coding standard, specifically MPEG-4 Part 2 Advanced Simple Profile (ASP). 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 .
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
Those codecs are used by many PC games which use voice chats via Microsoft DirectPlay API. Voxware MetaVoice Windows Media Player (voxmvdec.ax) Truespeech.

Workarounds still work on Windows 10 like VLC player, but free playback programs don't tend to support Blu-ray.
This is a listing of open-source codecs—that is, open-source software implementations of audio or video coding formats, audio codecs and video codecs respectively. Many of the codecs listed implement media formats that are restricted by patents and are hence not open formats.
Although sometimes compared to DivX products, Xvid is neither a container format nor a video format, it is a software library that encodes video using specific coding profiles of the common MPEG-4 ASP video format. Those types of restrictions are intended to simplify the construction of multimedia recorders and players.
Microsoft's Ben Waggoner states "Microsoft (well before my time) went down the codec standard route before with MPEG-4 part 2, which turns out to be a profound disappointment across the industry - it didn't offer that much of a compression advantage over MPEG-2, and the protracted license agreement discussions scared off a lot of adoption. I ...
The Combined Community Codec Pack, more commonly referred to by its acronym CCCP, is a collection of codecs (video compression filters) packed for Microsoft Windows, designed originally for the playback of anime fansubs. [2] The CCCP was developed and maintained by members of various fansubbing groups.
