The aim of this project is to provide the most complete implementation of the xiph.org codecs for Windows and Directshow. This includes decoders and encoders for all the xiph.org formats as well as annodex. It is released under a BSD license, so they can be used by both open-source and commercial applications.
Current State
Besides the directshow filters which many people are familiar with. The source distribution also contains many useful tools, for debugging and validating ogg files, which build on multiple platforms. There is also a .NET media player class which can basically provide an "instant" media player in any .NET application, as well as an early implementation of an apache2 module which can provide server side seeking (currently only of annodex files, but soon also ogg files)
More information about the libraries and tools that are available in the source distribution can be found in the developers section
In the pipeline
Many things are planned, I'm not committing solidly to anything! Though as at February 2006, you can expect to see a lot more development over the next few months, and hopefully for the rest of this year. We might get to 1.0 one of these years, with the goal being for the most complete, stable and user friendly solution for Xiph codecs on Windows.
I was really busy last year and didn't get to do much, hopefully 2006 will see a much shorter release cycle.
Contact me
If you have questions, bug reports, feedback, suggestions, or want to tell me about your projects using oggcodecs you can contact me via email at ogg@illiminable.com . I try to answer all email, if you email me and I don't respond within 7 days I am not ignoring you, your email probably got lost amongst all the spam, or I've gone on holidays! In either case, if I don't respond, email me again. Please make your subjects meaningful, so they are easy to spot amongst the spam. Don't attach files to your first email to me, that increases the chance it will be marked as spam. If you have something you want to send me, tell me in your first email, and then once I respond I will tell you how to get the file to me, or I'll be expecting an attachment from you.
You can also usually find me on IRC on Freenode servers (www.freenode.net) in #vorbis, #theora or #annodex. Remember I'm in Australia (GMT+8) so I'm more likely to respond in the afternoon/evening my time. My nick is illi.
You could also try the xiph.org mailing lists, such as vorbis-dev.
Or if you want to see the svn commit information on the web, you can spy on me here with CIA
