This means that this is a -development series leading up to a stable 0.10.x series. -You have been warned. +GStreamer: Release notes for GStreamer Base Plug-ins 0.9.3 "De Facto" + -GStreamer 0.9 development series - Hung by a Thread ---------------------------------------------------- +The GStreamer team is petrified to announce a new release +in the 0.9.x development series of the +GStreamer Base Plug-ins. -Starring - GSTREAMER +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. -The core around which all other modules revolve. Base functionality and -libraries, some essential elements, documentation, and testing. - BASE +This module contains a set of reference plugins, base classes for other +plugins, and helper libraries. -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. +This module is kept up-to-date together with the core developments. Element +writers should look at the elements in this module as a reference for +their development. -And introducing, for the first time ever, on the development screen ... +This module contains elements for, among others: - THE GOOD + device plugins: x(v)imagesink, alsa, v4lsrc, cdparanoia + containers: ogg + codecs: vorbis, theora + text: textoverlay, subparse + sources: sinesrc, videotestsrc, gnomevfssrc + network: tcp + typefind + audio processing: audioconvert, adder, audiorate, audioscale, volume + visualisation: libvisual + video processing: ffmpegcolorspace + aggregate elements: decodebin, playbin - --- "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 -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. +Other modules containing plug-ins are: -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 +gst-plugins-good +contains a set of well-supported plug-ins under our preferred license +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 - --- "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. - -- 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-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. - -INSTALLING FROM PACKAGES ------------------------- -You should always prefer installing from packages first. GStreamer is -well-maintained for a number of distributions, including Fedora, Debian, -Ubuntu, Mandrake, Gentoo, ... - -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. - -Find more information about the various packages at -http://gstreamer.freedesktop.org/download/ - -COMPILING FROM SOURCE TARBALLS ------------------------------- -- 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. - -- check output of ./configure --help to see if any options apply to you -- run - ./configure - make - - to build GStreamer. -- if you want to install it (not required), run - make install -- You should create a registry for things to work. - If you ran make install in the previous step, run - gst-register - as root. - - If you didn't install, run - tools/gst-register - as a normal user. - -- try out a simple test: - gst-launch fakesrc num_buffers=5 ! fakesink - (If you didn't install GStreamer, again prefix gst-launch with tools/) - - If it outputs a bunch of messages from fakesrc and fakesink, everything is - ok. - -- 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 using an application which -has a non-GPL compatible license (for instance a closed-source application) -with GStreamer, you have to make sure not to use 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. + + +Features of this release + + * Parallel installability with 0.8.x series + * Threadsafe design and API + * RTP base classes + +Bugs fixed in this release + + * 313251 : ximagesink unused functions + * 315159 : audioconvert lost 24 bit conversions in the rewrite + +Download + +You can find source releases of gst-plugins-base in the download directory: +http://gstreamer.freedesktop.org/src/gst-plugins-base/ + +GStreamer Homepage + +More details can be found on the project's website: +http://gstreamer.freedesktop.org/ + +Support and Bugs + +We use GNOME's bugzilla for bug reports and feature requests: +http://bugzilla.gnome.org/enter_bug.cgi?product=GStreamer + +Developers + +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.
