The OpenJPEG library is an open-source JPEG 2000 codec written in C language. It has been developed in order to promote the use of JPEG 2000, the new still-image compression standard from the Joint Photographic Experts Group (JPEG). In addition to the basic codec, various other features are under development, among them the JP2 and MJ2 (Motion JPEG 2000) file formats, an indexing tool useful for the JPIP protocol, JPWL-tools for error-resilience, a Java-viewer for j2k-images, ...Who can use the library ?
Anybody. As the OpenJPEG library is released under the BSD license, anybody can use or modify the library, even for commercial applications. The only restriction is to retain the copyright in the sources or the binaries documentation.
Who is developing the library ?
The library is developed by the Communications and Remote Sensing Lab (TELE), in the Université Catholique de Louvain (UCL), and CNES with the support of the CS company. The JPWL module is developped and maintained by the Digital Signal Processing Lab (DSPLab) of the University of Perugia, Italy (UNIPG). As our purpose is to make OpenJPEG really useful for those interested in the image compression field, any feedback/advices are obviously welcome ! We will do our best to handle them quickly.

Installation.
Among all the files present in the .tar.gz archive above, only the 'libopenjpeg' directory is needed to build the library. The 'codec' directory lets you build a basic codec using this library. Check the documentation for information on other modules.
A makefile is included for both linux and osx. Check the README files for more info. Note that some problems for compiling the dynamic library on AMD64 have been reported.
The ogmtools allow users to display information about (ogminfo), extract streams from (ogmdemux), merge several streams into (ogmmerge), and split (ogmsplit) Ogg files. Supported stream types include video streams from AVIs or Ogg files and Vorbis audio from Ogg files. The resulting files can be played back with mplayer or with the OggDS Direct Show filters under Windows.Download.

OggMux is the utility that I got my ideas from - but it's for Windows only. If you need it, header over to http://oggmux.sourceforge.net/ and grab a copy.
Another utility for Windows are the Ogg Media File tools that are command line utilities which are very alike to my ogmtools. Great stuff, Cyrius.
