So we've finally made it! The Schrodinger project has reached version 1.0 and we now have a high performance, compliant solution for Dirac encoding and decoding. The Schro team have produced a press release to mark the event.
Dave Schleef has been working really hard on this for a long time, so many congratulations to him for getting to this point.
We're now working on transport stream wrappings for the Dirac format and ffmpeg plugins for both the Dirac and Schro software. What I _hope_ to do over the next few months is to port across many of the compression algorithm ideas used in Dirac encoding (and some new ones) into the fast Schro encoder to improve its compression performance. Schro has a much more flexible architecture and we should be able to get much better compression in the long-term than with the Dirac codebase, which should eventually die.
We also want to look at more GPU acceleration, especially in the encoder (where we could have lots of GPUs if we liked), building on the work Wladamir van der Laan has been doing on the decoder.
Thanks again to Dave, and to everyone who's contributing to turning Dirac into a practical reality.

Congratulations! This is good news. Will there be an updated MPlayer patch for Dirac-1.0 ?
Can we see a screenshot or some video samples of what the codec is able to do? I'm very curious to compare quality. Ideally, someone should get some uncompressed video and encode it using the same bitrate using schrodinger, and other codecs such as x264 and xvid, and present some screenshots. If the codec is better, it should help start some good hype around the project, leading to a good takup in the future (when Windows codecs arrive)
