MPEG-2 Video / H.261

MPEG-2 (ISO/IEC 13818) is a standard from the Motion Pictures Expert Group, which defines a series of standards for compression support for TV quality transmission of digital video. The Video part (ISO/IEC 13818-2) of MPEG-2 is similar to MPEG-1, but also provides support for interlaced video (the format used by analog broadcast TV systems). MPEG-2 video is not optimized for low bit-rates (less than 1 Mbit/s), but outperforms MPEG-1 at 3 Mbit/s and above.

Overview of MPEG-2 Test Model 5

This document contains modified chapters from the original (now outdated) Test Model 5 document that pertain to MPEG-2 Video Main Profile.

Xine is a free gpl-licensed video player for unix-like systems. It plays mpeg-2 and mpeg-1 system (audio + video multiplexed) streams,
mpeg elementary streams (audio/video only, e.g. mp3 files) and
AVI files (using win32 codec dlls). Xine plays the video and audio data of the stream and synchronizes the playback of both. Depending on the properties of the stream, playback will need more or less processor power, full frame rate for mpeg-2 has been seen on a 400 MHz P II system.

Xine is on 1.1.7 as of June, 2007.

Gspot Codec Information Appliance

GSpot identifies presence or absence of “B-VOP”, “Qpel”, and “GMC”, thus allowing the user to determine if a DivX5 file is compatible with KISS and other popular hardware DivX players. Provides information about MPEG1 or MPEG2 video and/or MPEG1 or MPEG2 audio either as “elementary” streams or multiplexed into an MPEG1 “system stream” or an MPEG2 “program stream”. Limited support for MPEG4 video when contained in an AVI stream, such as DivX5.

Version 2.7a is shipping as of February, 2007.

The MPEG Industry Forum

Stated objective: To further the adoption of the MPEG-4 Standard, by establishing MPEG-4 as an accepted and widely used standard among application developers, service providers, content creators and end users..

Update: This group has now changed it’s name to The MPEG Industry Forum, and have expanded their charter to include all emerging MPEG standards. For right now that includes MPEG-7 and MPEG-21, but we’re not ruling out anything in the future.

mpeg2dec - a free MPEG-2 video stream decoder

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.
