GStreamer "Desperately Seeking Sexiness" 0.4.0 released
GStreamer "GEPpiness is a warm gun" 0.4.1 released [1]
The GStreamer team is happy to announce another release of the
GStreamer streaming-media framework. We are quickly moving forward at
this time and more and more applications using GStreamer are popping
up. Please see the [1]release page for availability of source and
binary packages.
GStreamer streaming-media framework. This release has mainly focused
on code clean-up and rounding out of the features. Large chunks of
GStreamer are API stable at this point. In preparation of a stable
release, we have also done a thorough license audit to make sure that
the licenses of all plug-ins are properly documented, and that as many
of them as possible are available under the LGPL license that
GStreamer uses.
We are starting to have a really nice collection of applications under
development using GStreamer. If you are looking for something specific
check out our [1]applications status page.
Updates and Enhancements
General
* Graphical pipeline editor (gst-editor) ported to GNOME 2.0
* Autobuild system using [2]bitches to generate good RPMs
* Apt for rpm repository for GStreamer and plug-in dependencies on
RedHat 7.2 and 7.3, for both Ximian Red-Carpet Gnome 2 and
Gnomehide. See [3]http://gstreamer.net/releases/redhat/
* Red-Carpet GStreamer channel under construction.
* GConf schemas distributed for centralised sink settings
* Moved to [4]http://bugzilla.gnome.org/ for bug reports. Bugzilla
is more convenient than SourceForge's system, and Gnome already
has a system running. Thanks to Gnome for the support.
* Created a gst-feedback script to gather system information to be
added to a bug report for better debugging.
* Further work on the Graphical Pipeline Editor, getting to be very
stable and well working.
* KDE/Qt bindings created for easier creation of KDE applications on
top of GStreamer
* General C++ bindings for use with gtkmm and other C++ projects
added to gst-bind module (in CVS)
* Effectv and virtualdub based plug-ins relicensed under LGPL
(previously GPL)
* Some manual examples updated and extracted to code (in
examples/manual)
Core
* New much improved registry system implemented.
* New event-driven seek support. Event system is now working and
implemented
* Header files are now in a versioned directory to ease build pains.
* Improvements and bugfixes todparams.
* Docs updated, registry and system clock documentation added
* More tests added for improved troubleshooting
* Cothreads code made more POSIX-compatible
* PowerPC portability fixes
* Many memleaks plugged
* Lots of code cleaning
* Many documentation improvements
* Small change to [2]Plugin API
* Removed use of -Wall and -Werror from release tarball for non-gcc
compilers, more permanent solution upcoming.
* Old schedulers renamed: we now use basicomega as the default
scheduler, with the others being fastomega, basicwingo and
fastwingo.
Plug-ins
* Quicktime plug-in rewritten
* [5]Effectv video effects plug-ins included
* Audio effect plug-ins fixes (int2float, floatcast etc.)
* A new filter plug-in for audio filters
* OSS plug-in fixes
* Audiofile plug-in works again (depends on upstream patch getting
included)
* lavencode plug-in renamed yuv4mpeg
* Synaesthesia plug-in added to gst-visualisation packages
* [6]Jack plug-in working and packaged -- CVS Jack required
* Floatcast plug-in added
* Include file setup fixes

* Better URI handling in gnome-vfs plug-in
* RTP plug-in updated and ported to the [7]oRTP library
* BSD and Darwin cd playing
* New Mixermatrix plugin added
* New Flash plugin added
* RTP plugin moved back to librtp and plugin now includes library
code (still experimental, check configure --help on how to enable)
* New v4l2 plugins
* Updated v4l plugins
* Improvements to dvdnav plugin
* iRadio support added to gnomevfs plugin
* Median video plugin updated and now working
* Fixed many major bugs in the gnome-vfs library
* Got rid of misleading warnings from plugins
* Avi muxer much improved
* Fix bug in mad plugin that caused loss of frames
* mp3 typefind fixed to properly handle id3v2 tags
Known Issues
GStreamer currently ships with two schedulers, named 'basic' and
'standard'. Basic is the one we have been shipping for a long time now
and is still the default in GStreamer 0.4.0. There are however some
limitations and threadrelated bugs in basic. These limitations are not
present in standard, but unfortunately standard does not work with
i686 glibc atm due to differences in the way threads are handled
compared to other architectures including i386. We hope to get the
remaining issues in standard fixed before 0.4.1 and use that as
default.
GStreamer currently ships with schedulers based on two cothread
packages. The 'omega' cothread package is the one we have been
shipping for a long time now and is still the default in this release.
There are however some limitations and thread-related bugs in the
omega scheduler. These limitations are not present in the 'wingo'
schedulers, but unfortunately it does not work with i686 glibc at this
time due to differences in the way threads are handled compared to
other architectures, including i386. A new (third) scheduler (that
doesn't use cothreads) is being developed.
As for the bugs in basic we did not feel they warranted not releasing
0.4.0 as they are rather obscure. For instance if you are using
Rhythmbox you will need to be playing over 500 songs nonstop to
trigger it.
As for the bugs in the 'omega' schedulers, we did not feel they
warranted not releasing 0.4.1 as they are rather obscure. For instance
if you are using Rhythmbox you will need to be playing over 500 songs
nonstop to trigger it. You can choose a different scheduler by passing
--scheduler=(name) to any GStreamer application.
If you want to test the standard scheduler, run your GStreamer
application with --gst-scheduler=standard
Wim Taymans has started work on a new scheduler. The first part is
already in CVS, but it will probably still be some months before it is
ready.

[1] It is a little-known fact that the Beatles decided their track
listing for their albums based on a process called the 'GEP' process.
After some initial problems, this worked very well. The only known
failure of this process happened when George Harrison commited the
out-of-place 'Within You Without You' to Sergeant Pepper without
review by the other band members. This near split-up led to one of
their finest songs on the world-reknowned White Album.
