Update: September 28, 2004
Version 1.2.3: Improved performance for XmtBatch conversion. Various
minor bug fixes and minor enhancements.
What is the 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
- 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.
Since the toolkit is Java-based, the client applications and the content
creation applications are cross-platform and will run on any platform that
The above applications are provided as demonstration of this toolkit. Those
who experiment with these applications and are interested in creating their own
applications can license the technologies.
How does it work?
AVgen and XmtBatch tools combine independently coded MPEG-4 media objects
into an MPEG-4 file.
AVgen can be used to generate audio- and video-only content and optionally
"hint" it for delivery over RTP/RTSP transport for both ISMA- and 3GPP-compliant
XMTBatch provides more comprehensive authoring facilities using MPEG-4
Systems, including graphics, animation, and user interaction.
The XMTBatch tool creates MPEG-4 binary content from the high-level textual
descriptions created in the XMT (Extensible MPEG-4 Textual Format in XML)
standard. It supports content created in the high-level format XMT-O (based on
the SMIL 2.0 syntax and semantics) as well as the low-level XMT-A format (based
on the X3D, VRML in XML). The XMTBatch tool also provides transcoding functions
for instance transforming from WMF (Windows Meta File) format to MPEG-4.
M4Play renders MPEG-4 content created by the above tools. The M4Play
application can render the following file types:
MP4: including MPEG-4 Systems
AVI: MPEG-4 Simple Profile video (such as Divx, Xvid) with MP3 audio.
MPEG-4 Simple Profile video (.cmp, .m4v, .263)
AAC Low-Complexity Profile audio (.aac, .adif, .adts)
MP3 MPEG-1 and MPEG-2 Layer 3 audio (.mp3)
