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
|
||
|
