x262

x262 is a free software library and application for encoding video streams into the MPEG-2 compression format, and is released under the terms of the GNU GPL.

Features Overview

x262 is an MPEG-2 encoder based on the best-in-class features of x264.
It also has the big advantage that the codec is simple enough for people new to video-compression to get involved.
