Release notes for GStreamer Base Plugins 1.1.90

The GStreamer team is proud to announce a new bug-fix release in the 1.x stable series of the core of the GStreamer streaming media framework.

The 1.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.10.x series. It is, however, parallel installable with the 0.10.x series and will not affect an existing 0.10.x installation.

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
  • libraries: app, audio, fft, pbutils, riff, rtp, rtsp, sdp, tag, video
Other modules containing plugins are:
contains a set of well-supported plugins under our preferred license
contains a set of well-supported plugins, but might pose problems for distributors
contains a set of less supported plugins that haven't passed the rigorous quality testing we expect, or are still missing documentation and/or unit tests
contains a set of codecs plugins based on libav (formerly gst-ffmpeg)
