Xiph is an open source project, and people are free to contribute what they think is useful under our general umbrella.
I've been more inspired to work on xiph stuff lately, largely because Emmett has left (I'm sorry to say) and (I'm not sorry to say at all) jack is asserting himself again.
Xiph has grown quite a bit lately, accreting several other projects, and it's gotten hard to keep follow everything that's going on or figure out how to contribute.
FLAC joined Xiph.Org Foundation - Hydrogenaudio Forums(Site not responding. Last check: 2007-10-13)
Now Xiph lacks on video codecs: Tarkin is in planning stage, Theora is alpha (even if they released the test suite) and the rumors about Tobias' join are still not made official.
I have proposed to Ben Rudiak-Gould to join the Xiph project with his lossless video codec called Huffyuv.
BTW, seems that open and free formats forces are becoming more powerful every day: now the problem is to convince some "altarnative" industries (KiSS Technology, for example) to adopt them "like standards" for the manufacturing of home entertainment equipments (portable, car, standalone players) and medias.
Other prominent Xiph codecs that are often encapsulated in Ogg are the video codec Theora, and the human speech audio compression format, Speex.
The current version of Xiph's free reference implementation, released on November 27, 2005, is libogg 1.1.3[1].
The Ogg bitstream format, spearheaded by the Xiph.org Foundation, has been created as the framework of a larger initiative aimed at developing a set of components for the coding and decoding of multimedia content which are both freely available and The format consists of chunks of data each called an Ogg Page.
The reference implementation libraries are licensed under Xiph's variant of the BSD License, a.k.a.
This is a trivial variation of the popular BSD License where the Xiph.org Foundation is substituted for the University of California, Berkeley.
The Xiph License is free enough that the libraries have been used in commercial products to implement FLAC, including in the firmware of hardware devices where other Open Source licenses can be problematic.
This is our native format and the recommended container for all Xiph codecs.

Monty of Xiph, on Patents and stuff | Dave's Stupid Website(Site not responding. Last check: 2007-10-13)
As a long-time lurker, I was watching when Monty appeared out of the blue with a bunch of patches to fix various bugs in Audacity, and since then he has contributed quite a bit of code to Audacity, in his spare time.
Since the interview was initiated, several of the questions became irrelevant (such as Theora entered beta after the interview started), but the questions are preserved here for the sake of continuity.
The USPTO has no budget to employ suffiecent competent reviewers, especuially given that the floodgates are open and they pay very little compared to what you can make in industry *filing* the patents instead of reviewing them.
Xiph QuickTime Components (XiphQT) is, in short, the solution for Mac and Windows users who want to use Xiph formats in any QuickTime-based application, e.g.
Intel Mac compatibility (finally!), FLAC decoder, fresh (and still warm!) Theora decoder and a number of bug fixes and other smaller changes - see the release notes for details.
In short, the project is a continuation of the efforts to bring availability of the Xiph.Org Foundation's free and open media formats into the Mac OS X environment, and do it in a way consistent with the well-defined and established media manipulation frameworks existing in that environment.
Wrapper format for Vorbis sound data and various other multimedia bitstreams developed by the Xiph open source project.
Ogg is called a "container" at http://wiki.xiph.org/CategoryTodo, part of the Xiph development site.
The About Xiph page (dated 1999 and signed by "Monty") presents a strong editorial statement in favor of open source approaches to networked information and against unwarranted corporate hegemony over music, performance, and the Internet.
Each version of quicktime uses dramatically different audio and visual formats (as well as image formats such as jpegs), and I am not sure of the various incarnations.
Vorbis is probably the most popular of the codecs to be developed out of the Xiph project.
OggTheora is the newest of the 4 codecs out of the Xiph audio project.

Also, check your firewall settings, because some mirrors may require that you do not block the HTTP referers.

Late last year the Xiph QuickTime Components project took up where the moribund qtcomponents.sourceforge.net had left off — great news for lovers of open audio formats like OggVorbis.
Xiph QuickTime Components (XiphQT) is, essentially, for Mac users who want to use Xiph formats in any QuickTime-based application, e.g.
I installed Xiph QT Component 0.1.3 on Tiger 10.4.5, QT 7.0.4 (Pro) and, yes, I (QT Player, iTunes 6.0.4) can play ogg-files, but there is no ogg-entry in the export-menu of QT Player.
Also, the Info-panel in iTunes classifies the ogg-files as "Quicktime movie file".
He's pooling his efforts with Xiph a bit and has decided to keep his work in xiph.org svn, in the 'vp32' module where the code was originally released.
Monty's been busy with unrelated contract work since finishing the zero-copy libogg, and no one has stepped up to act as maintainer in the meantime.
We've been working on a wiki todo for theora and for xiph generally.
There are several sites hosted by the developers themselves, who add to the icecast products customized features, cutting-edge items, or pre-built binaries for users.
As no page is ever static, the modules mentioned here may change over time on the Xiph page.
Experience has shown that the best method for installing icecast2 and related applications is to download all source code and then compile it later rather than downloading each program individually, compiling, and then downloading again.
