Release notes for GStreamer 0.7.4 "Wooden Eels"

The GStreamer team is happy to announce a new release in the 0.7.x development series of the GStreamer streaming-media framework. The goal of this release series is to stabilize towards a 0.8 release series which will be part of the GNOME 2.6 releases and hopefully eventually KDE 4.x.

The 0.7 series is a development series and is aimed at developers. It is NOT API or ABI compatible with the stable 0.6.x series or with other releases in the series. This means you can not use this release to upgrade your current GStreamer installation and expect your GStreamer applications to keep working without a recompile. It is, however, parallel installable with the 0.6.x series.

Features of this release

  • Merged the new caps system
  • Reworked pad negotiation
  • Internationalized core and elements
  • Reworked error notification with translated error messages and additional debug information for developer feedback
  • Updated Dutch and French translations
  • Reworked clocking
  • Serialization of GstValue
  • Documentation of GstCaps
  • Poisoning of GstCaps
  • Queues now flushed properly to fix seeking in playback
  • Memleak fixes in core elements
  • Largely rewritten Plug-in Writer's Guide
  • Unversioned tools that wrap all present and future versioned tools to help packagers
  • Portability fixes for Solaris and OSX
  • Lots of bugfixes

Please submit patches via bugzilla as well.

For help and support, please subscribe to and send questions to the gstreamer-devel mailing list (see below for details).

Git is hosted on You can browse the gstreamer repository.

All code is in Git and can be checked out from there.

Interested developers of the core library, plugins, and applications should subscribe to the gstreamer-devel list.


As mentioned there are some changes in API/ABI between the 0.6.x and 0.7.x releases. Many applications will probably be source compatible between 0.6.x. and 0.7.x however. Rhythmbox and Sound Juicer for instance work very well when compiled on 0.7.x. GStreamer Player does not work across releases however, so we will make a separate release of gst-player with the needed fixes for it to work with 0.7.x. This release contains the core fixes we were waiting for to port the player over so expect a gst-player release in the near future.
