WHAT IT IS
----------
GStreamer: Release notes for GStreamer Good Plug-ins 0.9.6 "Everything's Not Lost"
This is GStreamer, a framework for streaming media.
The GStreamer team is petrified to announce a new release
in the 0.9.x development series of the
GStreamer Good Plug-ins.
WHERE TO START
--------------
We have a website at
http://gstreamer.freedesktop.org/
The 0.9.x series is a development series and not recommended for end users.
It is not API or ABI compatible with the stable 0.8.x series.
It is, however, parallel installable with the 0.8.x series.
You should start by going through our FAQ at
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/faq/html/
There is more documentation; go to
http://gstreamer.freedesktop.org/documentation
"Such ingratitude. After all the times I've saved your life."
You can subscribe to our mailing lists; see the website for details.
We track bugs in GNOME's bugzilla; see the website for details.
You can join us on IRC - #gstreamer on irc.freenode.org
GStreamer 0.10 series
---------------------
Starring
GSTREAMER
The core around which all other modules revolve. Base functionality and
libraries, some essential elements, documentation, and testing.
BASE
A well-groomed and well-maintained collection of GStreamer plug-ins and
elements, spanning the range of possible types of elements one would want
to write for GStreamer.
And introducing, for the first time ever, on the development screen ...
THE GOOD
--- "Such ingratitude. After all the times I've saved your life."
A collection of plug-ins you'd want to have right next to you on the
battlefield. Shooting sharp and making no mistakes, these plug-ins have it
@ -21,81 +49,199 @@ all: good looks, good code, and good licensing. Documented and dressed up
in tests. If you're looking for a role model to base your own plug-in on,
here it is.
If you find a plot hole or a badly lip-synced line of code in them,
let us know - it is a matter of honour for us to ensure Blondie doesn't look
like he's been walking 100 miles through the desert without water.
THE UGLY
This module contains a set of plug-ins that we consider to have good quality
--- "When you have to shoot, shoot. Don't talk."
There are times when the world needs a color between black and white.
Quality code to match the good's, but two-timing, backstabbing and ready to
sell your freedom down the river. These plug-ins might have a patent noose
around their neck, or a lock-up license, or any other problem that makes you
think twice about shipping them.
We don't call them ugly because we like them less. Does a mother love her
son less because he's not as pretty as the other ones ? No - she commends
him on his great personality. These plug-ins are the life of the party.
And we'll still step in and set them straight if you report any unacceptable
behaviour - because there are two kinds of people in the world, my friend:
those with a rope around their neck and the people who do the cutting.
THE BAD
--- "That an accusation?"
No perfectly groomed moustache or any amount of fine clothing is going to
cover up the truth - these plug-ins are Bad with a capital B.
They look fine on the outside, and might even appear to get the job done, but
at the end of the day they're a black sheep. Without a golden-haired angel
to watch over them, they'll probably land in an unmarked grave at the final
showdown.
Don't bug us about their quality - exercise your Free Software rights,
patch up the offender and send us the patch on the fastest steed you can
steal from the Confederates. Because you see, in this world, there's two
kinds of people, my friend: those with loaded guns and those who dig.
You dig.
The Lowdown
-----------
--- "I've never seen so many plug-ins wasted so badly."
GStreamer Plug-ins has grown so big that it's hard to separate the wheat from
the chaff. Also, distributors have brought up issues about the legal status
of some of the plug-ins we ship. To remedy this, we've divided the previous
set of available plug-ins into four modules:
- gst-plugins-base: a small and fixed set of plug-ins, covering a wide range
of possible types of elements; these are continuously kept up-to-date
with any core changes during the development series.
- We believe distributors can safely ship these plug-ins.
- People writing elements should base their code on these elements.
- These elements come with examples, documentation, and regression tests.
- gst-plugins-good: a set of plug-ins that we consider to have good quality
code, correct functionality, our preferred license (LGPL for the plug-in
code, LGPL or LGPL-compatible for the supporting library).
We believe distributors can safely ship these plug-ins.
People writing elements should base their code on these elements.
Other modules containing plug-ins are:
- We believe distributors can safely ship these plug-ins.
- People writing elements should base their code on these elements.
- gst-plugins-ugly: a set of plug-ins that have good quality and correct
functionality, but distributing them might pose problems. The license
on either the plug-ins or the supporting libraries might not be how we'd
like. The code might be widely known to present patent problems.
- Distributors should check if they want/can ship these plug-ins.
- People writing elements should base their code on these elements.
gst-plugins-base
contains a basic set of well-supported plug-ins
gst-plugins-ugly
contains a set of well-supported plug-ins, but might pose problems for
distributors
gst-plugins-bad
contains a set of less supported plug-ins that haven't passed the
rigorous quality testing we expect
- gst-plugins-bad: a set of plug-ins that aren't up to par compared to the
rest. They might be close to being good quality, but they're missing
something - be it a good code review, some documentation, a set of tests,
a real live maintainer, or some actual wide use.
If the blanks are filled in they might be upgraded to become part of
either gst-plugins-good or gst-plugins-ugly, depending on the other factors.
- If the plug-ins break, you can't complain - instead, you can fix the
problem and send us a patch, or bribe someone into fixing them for you.
- New contributors can start here for things to work on.

Bugs fixed in this release
INSTALLING FROM PACKAGES
------------------------
Download
You should always prefer installing from packages first. GStreamer is
well-maintained for a number of distributions, including Fedora, Debian,
Ubuntu, Mandrake, Gentoo, ...
You can find source releases of gst-plugins-good in the download directory:
http://gstreamer.freedesktop.org/src/gst-plugins-good/
Only in cases where you:
- want to hack on GStreamer
- want to verify that a bug has been fixed
- do not have a sane distribution
should you choose to build from source tarballs or CVS.
GStreamer Homepage
Find more information about the various packages at
http://gstreamer.freedesktop.org/download/
More details can be found on the project's website:
http://gstreamer.freedesktop.org/
COMPILING FROM SOURCE TARBALLS
------------------------------
Support and Bugs
- again, make sure that you really need to install from source !
If GStreamer is one of your first projects ever that you build from source,
consider taking on an easier project.
We use GNOME's bugzilla for bug reports and feature requests:
http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer
- check output of ./configure --help to see if any options apply to you
- run
./configure
make
Developers
to build GStreamer.
- if you want to install it (not required, but what you usually want to do), run
make install
CVS is hosted on cvs.freedesktop.org.
All code is in CVS and can be checked out from there.
Interested developers of the core library, plug-ins, and applications should
subscribe to the gstreamer-devel list. If there is sufficient interest we
will create more lists as necessary.
- try out a simple test:
gst-launch -v fakesrc num_buffers=5 ! fakesink
(If you didn't install GStreamer, prefix gst-launch with tools/)
Applications
Contributors to this release
* Andy Wingo
* Edgard Lima
* Edward Hervey
* Jan Schmidt
* Julien Moutte
* Michael Smith
* Thomas Vander Stichele
* Tim-Philipp Müller
* Vincent Torri
* Wim Taymans
 
If it outputs a bunch of messages from fakesrc and fakesink, everything is
ok.
If it did not work, keep in mind that you might need to adjust the
PATH and/or LD_LIBRARY_PATH environment variables to make the system
find GStreamer in the prefix where you installed (by default that is /usr/local).
- After this, you're ready to install gst-plugins, which will provide the
functionality you're probably looking for by now, so go on and read
that README.
COMPILING FROM CVS
------------------
When building from CVS sources, you will need to run autogen.sh to generate
the build system files.
You will need a set of additional tools typical for building from CVS,
including:
- autoconf
- automake
- libtool
autogen.sh will check for recent enough versions and complain if you don't have
them. You can also specify specific versions of automake and autoconf with
--with-automake and --with-autoconf
Check autogen.sh options by running autogen.sh --help
autogen.sh can pass on arguments to configure - you just need to separate them
from autogen.sh with -- between the two.
prefix has been added to autogen.sh but will be passed on to configure because
some build scripts like that.
When you have done this once, you can use autoregen.sh to re-autogen with
the last passed options as a handy shortcut. Use it.
After the autogen.sh stage, you can follow the directions listed in
"COMPILING FROM SOURCE"
You can also run your whole cvs stack uninstalled. The script in
the gstreamer module /docs/faq/gst-uninstalled) is helpful in setting
up your environment for this.
PLUG-IN DEPENDENCIES AND LICENSES
---------------------------------
GStreamer is developed under the terms of the LGPL (see LICENSE file for
details). Some of our plug-ins however rely on libraries which are available
under other licenses. This means that if you are distributing an application
which has a non-GPL compatible license (for instance a closed-source
application) with GStreamer, you have to make sure not to distribute GPL-linked
plug-ins.
When using GPL-linked plug-ins, GStreamer is for all practical reasons
under the GPL itself.
HISTORY
-------
The fundamental design comes from the video pipeline at Oregon Graduate
Institute, as well as some ideas from DirectMedia. It's based on plug-ins that
will provide the various codec and other functionality. The interface
hopefully is generic enough for various companies (ahem, Apple) to release
binary codecs for Linux, until such time as they get a clue and release the
source.
