Release notes for GStreamer Base Plug-ins 0.10.33 "Relaxing Distractions"
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 functions
audio processing: audioconvert, adder, audiorate, audioresample, volume
visualisation: libvisual
video processing: ffmpegcolorspace
aggregate elements: uridecodebin, playbin2, decodebin2, decodebin, playbin, encodebin
libraries: app, audio, cdda, fft, interfaces, netbuffer, pbutils, riff, rtp, rtsp, sdp, tag, video
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
