<ulink url="http://www.xvid.org">XviD</ulink> is an free software MPEG-4 ASP
compliant video codec, which features two-pass encoding and full MPEG-4 ASP
support, making it a lot more efficient than the well-known DivX codec.
It yields very good video quality and good performance due to CPU
optimizations for most modern processors.

It began as a forked development of the OpenDivX codec.
This happened when ProjectMayo changed OpenDivX to closed source
DivX4 (now DivX5), and the non-ProjectMayo people working on OpenDivX got angry,
then started XviD. So both projects have the same origin.

It is currently available only from CVS. Here are download and installation
instructions (you need at least autoconf 2.50, automake and libtool):
Like most open source software, it is available in two flavors:
<ulink url="http://www.xvid.org/downloads.html">official releases</ulink>
and the CVS version.
The CVS version is usually stable enough to use, as most of the time it
features fixes for bugs that exist in releases.
