Release notes for GStreamer Base Plugins 1.9.2

The GStreamer team is pleased to announce the second release of the unstable 1.9 release series, which marks the feature freeze for 1.10. The 1.9 release series is adding new features on top of the 1.0, 1.2, 1.4, 1.6 and 1.8 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework. The unstable 1.9 release series will lead to the stable 1.10 release series in the next weeks. Any newly added API can still change until that point.

Binaries for Android, iOS, Mac OS X and Windows will be provided in the next days.

This module contains a set of reference plugins, base classes for other plugins, and helper libraries. It also includes essential elements such as audio and video format converters, and higher-level components like playbin, decodebin, encodebin, and discoverer. 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. This module contains elements for, among others:

  • device plugins: x(v)imagesink, alsa, v4lsrc, cdparanoia
  • containers: ogg
  • codecs: vorbis, theora
  • text: textoverlay, subparse
  • sources: audiotestsrc, videotestsrc, giosrc
  • network: tcp
  • typefind functions
  • audio processing: audioconvert, adder, audiorate, audioresample, volume
  • visualisation: libvisual
  • video processing: videoconvert, videoscale
  • high-level components: playbin, uridecodebin, decodebin, encodebin, discoverer

Other modules containing plugins are:
