Release notes for GStreamer Good Plug-ins 0.10.31 "Faster"

The GStreamer team is proud to announce a new release
in the 0.10.x stable series of the
GStreamer Good Plug-ins.

The 0.10.x series is a stable series targeted at end users.

"Such ingratitude.  After all the times I've saved your life."

A collection of plug-ins you'd want to have right next to you on the
battlefield.  Shooting sharp and making no mistakes, these plug-ins have it
all: good looks, good code, and good licensing.  Documented and dressed up
in tests.  If you're looking for a role model to base your own plug-in on,
here it is.

If you find a plot hole or a badly lip-synced line of code in them,
let us know - it is a matter of honour for us to ensure Blondie doesn't look
like he's been walking 100 miles through the desert without water.

This module contains a set of plug-ins that we consider to have good quality
  code, correct functionality, our preferred license (LGPL for the plug-in
  code, LGPL or LGPL-compatible for the supporting library).
We believe distributors can safely ship these plug-ins.
People writing elements should base their code on these elements.

Other modules containing plug-ins are:

contains a basic set of well-supported plug-ins
contains a set of well-supported plug-ins, but might pose problems for
contains a set of less supported plug-ins that haven't passed the
    rigorous quality testing we expect
