Release notes for GStreamer Base Plug-ins 0.10.26 "You will know when you get there"

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
  • network: tcp
  • typefind
  • audio processing: audioconvert, adder, audiorate, audioscale, volume
  • visualisation: libvisual
  • video processing: ffmpegcolorspace
  • aggregate elements: 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

Features of this release

  • playbin2: make about-to-finish signal work for raw sources (e.g. audio CDs)
  • playbin2: fix handling of the native audio/video flags
  • playbin2: add flag to enable decodebin buffering
  • playbin2: make subtitle error handling more robust and ignore late errors
  • playbin2: improve subtitle passthrough in uridecodebin
  • playbin2: new subtitleoverlay element for generic subtitle overlaying
  • playbin2: proxy notify::volume and notify::mute from the volume/mute elements (or audio sink)
  • playbin2: don't stop completely on initialization errors from subtitle elements; instead disable the subtitles and play the other parts of the stream
  • decodebin2: rewrite autoplugging and how groups of pads are exposed
  • uridecodebin: add use-buffering property that will perform buffering on parsed or demuxed media.
  • GstXOverlay: flesh out docs and add example for use with Gtk+ >= 2.18
  • libgsttag: add utility functions for ISO-639 language codes and tags (packagers: this entails a new soft dependency on the iso-codes package)
  • oggdemux: use internal granulepos<->timestamp mapper and make oggdemux more like a 'normal' demuxer that outputs timestamps
  • oggdemux: seeking improvements
  • subparse: add qttext support
  • ffmpegcolorspace: prefer transforming alpha formats to alpha formats and the other way around
  • libgstvideo: add functions to create/parse still frame events.
  • theoraenc: make the default quality property 48.
  • videotestsrc: add pattern with out-of-gamut colors
  • theora: port to 'new' theora 1.0 API; make misc. existing properties have no effect (quick, keyframe-mindistance, noise-sensitivity, sharpness, keyframe_threshold); those either never worked or aren't needed/provided/useful any longer with the newer API
  • typefinding: misc. performance improvements and fixes
  • baseaudiosink: make drift tolerance configurable
