0.8.1 release of GStreamer core and plugins

GStreamer: Release notes for GStreamer Plugins 0.8.1 "Comforting Sounds"

The GStreamer team is happy to announce a new release in the 0.8.x stable series of the GStreamer Plugins.

The 0.8.x series is a stable series aimed at end users. It is not API or ABI compatible with the stable 0.6.x series. It is, however, parallel installable with the 0.6.x series.

This module contains plugins providing media encoding and decoding, conversion, effects, and other elements that provide actual media handling functionality to the core. You need the GStreamer core module to make them work. The versions do not need to match exactly, as long as all of them are in the 0.8.x series.

The FFmpeg-based decoder element has been moved to its own module. If you want support for a lot of popular video formats, you need to install this module along with the GStreamer Core and Plugins. An FFmpeg-based colorspace element has been added to the Plugins however.

Features of this release

  • Parallel installability with 0.6.x series
  • Internationalization
  • New translations in this release: Swedish, Afrikaans, Azerbeaijani
  • Translations: af az nl sr sv
  • Updated to the new core 0.8 subsystems
  • Reworked play and media-info libraries

  • Fixes to all other elements, including level, videodrop, gnomevfssrc, speex, *law, mpeg2dec, adder, a52dec, oggdemux, matroska, mad, v4l2, cacasink

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. If there is sufficient interest we will create more lists as necessary.

Applications

The GConf settings have moved to a versioned location and can now be found under /system/gstreamer/0.8. Applications should use the gconf library, as provided by gstreamer-gconf-0.8.pc/, to access the default settings.

GNOME Platform Bindings 2.6.0

GNOME Platform Bindings

The GNOME Platform Bindings provide a stable GNOME development platform for programming languages other than C, in the style of those languages. This release offers stable APIs for the GNOME 2.6 Platform in C++, Java, and Perl:
http://www.gnome.org/start/2.5/bindings/modules.html

These bindings follow these rules:
http://developer.gnome.org/dotplan/bindings/rules.html

Note that those rules do not guarantee 100% API coverage, but they do guarantee API/ABI stability.

Note that other bindings also exist:
http://www.gtk.org/bindings.html
but they were not on this release schedule and they do not necessarily follow the same rules.

If you have questions about the GNOME Platform Bindings release set please send email to language-bindings@gnome.org. If you have questions about the individual bindings, please send email to their own mailing lists. You can find links to the individual projects here: http://www.gnome.org/start/2.5/bindings/modules.html

Download

You can download source tarballs from
ftp://ftp.gnome.org/pub/GNOME/bindings/2.6/2.6.0/

Changes, for each binding, since their GNOME-2.4-based releases:

  • C++ (gtkmm):

    gtkmm:

    Highlights:

    • There are several new widgets/classes, with examples:
      • New File Chooser: FileChooser, FileChooserWidget, FileChooserDialog, FileFilter classes.
      • Action-based Toolbar/Menu API: UIManager, Action, ToggleAction, RadioAction classes
      • New Combo Box: ComboBox, ComboBoxEntry, ComboBoxText, CellLayout classes
      • Auto-complete for Entry: EntryCompletion class
      • Other new classes: IconInfo, IconTheme TargetList
      • New ATK, Pango, and GDK API wrapped

      • Alignment: Added set/get_padding()
      • Entry: Added set/get_alignment()

      • ListStore/TreeStores: Added insert_after(), which should be faster than insert().
      • TreeView: Added move_column_to_start()
      • TreeModel: Deriving is now easier, because the virtual functions now use C++ types.
      • TreeModel::iterator: Added operator--(), which is slow
      • See the NEWS file for detailed API changes
    • gnome-vfsmm:

      This API is now complete and API-stable.

    • libgnomecanvasmm:
      • Canvas: set_dither(), get_dither(): Use C++ enum instead of C enum.
      • Item: draw(): Use C++ Gdk::Drawable instead of C type.

    • libgnomeuimm:
      • Added icon-lookup() and icon_lookup_sync() functions.

Overview of Changes in Glib 1.042

Since 1.02x (the previous stable series)

  • Updated build requirement
    • ExtUtils::Depends >= 0.2
  • Support for a few new API features in glib-2.4.x.
  • Functions that use GErrors in C throw magical Glib::Error exception objects; these objects overload the stringification operator, so old code won't be broken, but new code can match errors without worrying about translated error messages. User code and other extensions can register their own error domains. See the Glib::Error

    manpage for more info.

  • Glib::Type enhancements
    • Perl code can register enum and flags types for use as Glib::Object

      property types.

    • During Glib::Object class initialization, invoke INIT_BASE in the object's package, if it exists. (Analogue for GTypeClass's base_init.)
    • It is now possible to add GInterface implementations to Glib::Object

      types derived in Perl code.

    • New param spec, Glib::ParamSpec::scalar
  • Glib::MakeHelper is generally more helpful.
  • The POD generation tools allow specification of cumulative data type

    descriptions, and much finer control over the format and content of the generated documentation.

  • Glib can now export useful constants on request.
  • New versioning API, see Glib::version.

Overview of Changes in Gtk2 1.040

Since 1.02x (the previous stable series)

  • Updated requirements:
    • Glib >= 1.040
    • ExtUtils::Depends >= 0.2 (required only at build time)
    • ExtUtils::PkgConfig >= 1.03 (require only at build time)
  • Add support for new objects and API in gtk+-2.4.0.
  • Derivation of Gtk2::CellRenderer has been reworked; it's much more sane now, but we retain backward compatibility with the 1.02x code.
  • It is now possible to implement GInterfaces in Perl code, so you can now implement your own Gtk2::TreeModels and Gtk2::CellEditables.

    Examples are included.

  • The SPLICE operation is now supported on Gtk2::SimpleList's tied data.
  • New, standardized versioning API and documentation.
  • Documentation enhancements all around.
  • Huge test suite expansion and amazing increase in API coverage.
  • New utility module Gtk2::TestHelper wraps up some of the boilerplate

    involved in testing Gtk2-based modules.

Overview of Changes in Gtk2::GladeXML 1.00

This is the first stable release.

Overview of Changes in Gnome2::Canvas 1.00

This is the first stable release.

Overview of Changes in Gnome2::VFS 1.001

  • Made all version checks refer to stable releases.
  • Made the test suite more robust.

Overview of Changes in Gnome2::GConf 1.000

This is the first stable release.

Overview of Changes in Gnome2 1.00

This is the first stable release.
