Release notes for GStreamer Base Plug-ins 0.10.27 "No Mistakes Allowed"

The GStreamer team is proud to announce a new release in the 0.10.x stable series of the GStreamer Base Plug-ins.

The 0.10.x series is a stable series targeted at 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.

This module contains a set of reference plugins, base classes for other plugins, and helper libraries. 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, gnomevfssrc, giosrc
  • network: tcp
  • typefind
  • audio processing: audioconvert, adder, audiorate, audioresample, volume
  • visualisation: libvisual
  • video processing: ffmpegcolorspace
  • aggregate elements: uridecodebin, decodebin2, playbin2, decodebin, playbin
Other modules containing plug-ins are:
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
