MPEG-4 Visual / H.263

MPEG-4 is an ISO standard (ISO/IEC international standard 14496) developed by the Moving Picture Experts Group (MPEG). It defines the deployment of non-proprietary multimedia content independently of platform or transmission medium. It has relied on and taken from a number of existing technologies while at the same time add-ing a number of innovative tools and concepts. MPEG-4 Visual (ISO/IEC 14496-2) - part of MPEG-4 standart for visual data coding. Motivated by the need for low bit rate (less than 64 kbps) video communication, the ITU-T initiated the work on the H.263 coding standard in 1993. Although its coding structure is based on that of H.261, H.263 supports new baseline coding methods as well as four optional modes that provide better picture quality at low bit rates with little additional complexity.

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.

IBM Toolkit for MPEG-4

The IBM Toolkit for MPEG-4 consists of a set of JavaTM classes and APIs with five sample applications: three cross-platform playback applications and two tools for generating MPEG-4 content for use with MPEG-4-compliant devices. These applications are as follows:

  • AVgen: a simple, easy-to-use GUI tool for creating audio/video-only content for ISMA- or 3GPP-compliant devices
  • XMTBatch: a tool for creating rich MPEG-4 content beyond simple audio and video
  • M4Play: an MPEG-4 client playback application
  • M4Applet for ISMA: a Java player applet for ISMA-compliant content
  • M4Applet for HTTP: a Java applet for MPEG-4 content played back over HTTP.

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.

XViD Quantizer Parser (XvidQP)

XVidQP is a tool that is designed to tell you something about the quality of an MPEG-4 stream. It does this by giving you a batch of reports, including:

  • Quantization values of I-Frames and P-Frames
  • Average quantizer value of I-Frames and P-Frames
  • Graphical histogram distribution of global clip quantizers
  • Minimum and maximum frame sizes of all frames

It looks right now like this tool is only shipping for Win32.

Beta 3 was shipping as of March, 2003.

MPEG-4 encoding on a cell phone?

This article describes a proof-of-concept app running on a Nokia 7650 that performs MPEG-4 encoding and decoding, creating a portable video phone. No word on how you can get the code, or how difficult it would be to port this Symbios OS product to other platforms. Still, the company that developed the product, Hantro Products, does supply the codecs that do the trick.

MPEG-4 foe calls for antitrust probe
