MPEG is actually an acronym for the Moving Pictures Experts Group, which is responsible for a body of standards regarding digitized video. The family of standards that are grouped under the MPEG umbrella cover a wide variety of compression techniques for motion pictures. Note that the MPEG standards by necessity include compression techinques for audio. Some of these techniques are categorized separately in the MP3 topic.
Salyens offers high-quality video codecs, including H.263, H.263+, H.264 (MPEG-4 AVC Part 10) and MPEG-4 Part 2, with a focus on standard compliant video conferencing and RTP streaming applications.
These codecs are also integrated, along with several audio codecs such as AMR NB and G.7xx, into the Smeet SDK and SmeetX.

GPAC is an implementation of the MPEG-4 Systems standard (ISO/IEC 14496-1) developed from scratch in ANSI C.
The main development goal is to provide a clean (a.k.a. readable by as many people as possible), small and flexible alternative to the MPEG-4 Systems reference software. The MPEG-4 Reference software is indeed a very large piece of software, designed to verify the standard rather than provide a small, production-stable software.
GPAC is written in ANSI C for portability reasons (embedded platforms and DSPs) with a simple goal: keep the memory footprint as low as possible.
The project will at term provide a 2D/3D core player, complete MPEG-4 Systems encoders and publishing tools for content distribution.

A GPL product, with the following description from the site:
mpeg2dec is an mpeg-1 and mpeg-2 video decoder. It is purposely kept simple : it does not include features like reading files from a DVD, output picture scaling, audio decoding, synchronisation, etc... The main purpose of mpeg2dec is to have a simple test bed for libmpeg2. mpeg2dec also includes a demultiplexer for mpeg-1 and mpeg-2 program streams, and output routines for a variety of different interfaces.
