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
* Parallel installability with 0.8.x series
* Threadsafe design and API
* 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
* 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
