[2]Previous Issues of Ogg Traffic
1 Status Updates
1.1 Monty
Besides committing a few minor bugfixes to libogg, Monty spent a lot
of time on postfish. Postfish is a sound postprocessor with noise
filter, and Monty has been spending a lot of time on developing a
revolutionary declipping filter for it.
Vorbis 1.1 is still on the agenda, too, but it's still in the thinking
stages. Monty did say, however, that some of his postfish work will
also be applicable to improve Vorbis, although he did not go into any
details about the connection.
1.2 Jean-Marc Valin
Jean-Marc wins the Committer of the Month title by a wide margin due
to his untiring efforts to produce a fixed-point version of [3]Speex.
Incremental partial implementations are available in the unstable
1.1.1 and 1.1.2 releases from November 1 and November 11,
respectively.
He also released the latest bug fixes on the stable branch as Speex
1.0.3.
1.3 Stan Seibert
Stan fixed a few positron bugs, and he rolled out the libao 0.8.4
release. Read more about libao below in the News section.
1.4 Manuel Lora
Manuel made a few adjustments to the Positron documentation, and he
helped out Ed with the Icecast documentation.
1.5 Warren Dukes
Warren helped out Stan with libao by providing a number of corrections
and improvements to the alsa09 plugin.
1.6 Chris Cheney
Chris helped Stan with the libao 0.8.4 release, and he added some
sanity to the ogg, vorbis, and vorbis-tools automake files.
1.7 Ed Zaleski
Ed aka Oddsock committed icecast2 documentation and various icecast2
bugfixes in preparation for the Icecast 2 Beta 1 release. He also
helped beat the Win32 SDK for Vorbis 1.0.1 into shape.
1.8 Brendan Cully
Brendan committed some fixes to icecast's and ices' autoconf feng
shui.
1.9 Karl Heyes
Karl fixed a number of icecast2 bugs and memory leaks.
1.10 Ralph Giles
Ralph was once again all over the map, helping along the Vorbis 1.0.1
release with numerous autotools and SDK improvements, and checking in
various improvements to Theora. Among other cleanups, he changed
Theora's coordinate system back to VP3's to facilitate lossless
transcoding from VP3 to Theora. This breaks compatibility with alpha
2, but it was inevitable. Since he was already breaking compatibility,
he added some more header fields for future encoder improvements.
1.11 Timothy Terriberry
Timothy committed a couple of bug fixes to Theora's dump_video decoder
example.
1.12 Arc Riley
Arc has done some more work on libwrit (see
[4]http://wiki.xiph.org/OggWrit), and has begun implementing py-ogg2
(python bindings to libogg2) and a python-based IceTracker, the server
part of IceShare. More details about IceShare are below in the News
section.
2 News and Recent Developments
2.1 New Mailing List for Announcements
[5]announce at xiph.org is a low volume mailing list that allows Xiph
fans to stay up-to-date on events in the world of the Fish without
having to subscribe to every single project's mailing list. This list
distributes general news and announcements by the Xiph team, as well
as the text version of Ogg Traffic.
To subscribe to this list, send an email with the word "subscribe" in
the body (not in the subject line) to [6]announce-request at xiph.org.
2.2 Xiph.org at SCALE
I am pleased to announce that Xiph.org will be present at the Second
Annual [7]Southern California Linux Expo in LA on November 22, 2003.
Jack, Ralph, Nathan, Manuel, and I will take turns manning our booth,
and Monty will give a presentation entitled "The State of Open Source
and Multimedia: Technical Asphalt, Political Potholes and Tabloid
Gossip."
If you're in the area, this is a good opportunity to meet us face to
face, to ask questions, or to show support for our cause.
2.3 New Releases
2.3.1 libao 0.8.4
On October 5, 2003, Stan released the latest version of Xiph's
cross-platform audio output library, [8]libao. This release contains
improved pluging detection, new output plugins for AIX and NAS,
portability fixes for many platforms, and many other fixes.
2.3.2 Vorbis 1.0.1
It took a little longer than expected, but Vorbis 1.0.1 is finally
out. Special thanks go to John Edwards, Case, and Oddsock for making
sense of the Win32 issues, and to Warren Dukes for providing updated
RPM specs.
Detailed information about what's new in this release can be found in
the [9]ChangeLog. Get the goods at
[10]http://www.vorbis.com/download.psp.
2.3.3 Icecast 2.0 Beta 1
The Icecast development team proudly announces the first official beta
of Icecast 2, Xiph.org's new and improved streaming server for Ogg
Vorbis and MP3. The alpha versions were already quite stable, so this
beta should be relatively short lived, and it defines the feature set
for Icecast 2.0.
Planned features for future releases are listed on
[11]http://wiki.xiph.org/Icecast2ReleasePlan. For more information and
downloads, head on over to the [12]Icecast web pages.
2.3.4 Speex 1.0.3
Jean-Marc concludes the list of new releases with a [13]Speex 1.0.3
bugfix release. Among other minor bugfixes, this release corrects a
multithreading bug and an underflow problem that could cause a
dramatic decoding slowdown on x86 processors.
2.4 IceShare
Iceshare is a pseudo-P2P system that's currently under development. It
will be useable for streaming static Ogg files and continuous streams
and support "on the fly" bitrate switching with multibitrate streams.
Technical specs are available at [14]http://wiki.xiph.org/IceShare.
The project would benefit from Python, Java, and C developers to help
build a suite of Iceshare player toolsets at this point in
development. Contact Arc Riley <[15]arc at xiph.org> for more details.
