A significant milestone in open source multimedia: A group of highly dedicated and talented multimedia hackers has successfully reverse engineered the QDesign Music Codec (fourcc: QDM2) and released an open source decoder implementation. As usual, it is a piece of the FFmpeg project and the source code is available in the FFmpeg CVS repository, just waiting to be plugged into any libavcodec-using application. Be sure to pass the proper extradata through to the decoder.

There are very few QuickTime files that can not be played using open source software.

Thanks to all the folks who were involved in this effort: Ewald Snel, Benjamin Larsson, Alex Beregszaszi, and Roberto Togni.
