Release notes for GStreamer Good Plugins 1.0.2

The GStreamer team is proud to announce a new bug-fix release in the 1.x stable series of the core of the GStreamer streaming media framework.

The 1.x series is a stable series targeted at end users. It is not API or ABI compatible with the stable 0.10.x series. It is, however, parallel installable with the 0.10.x series and will not affect an existing 0.10.x installation.

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

A collection of plugins you'd want to have right next to you on the battlefield. Shooting sharp and making no mistakes, these plugins 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 plugin 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 plugins that we consider to have good quality code, correct functionality, our preferred license (LGPL for the plugin code, LGPL or LGPL-compatible for the supporting library). We believe distributors can safely ship these plugins. People writing elements should base their code on these elements.

Other modules containing plugins are:

contains a basic set of well-supported plugins
contains a set of well-supported plugins, but might pose problems for distributors
contains a set of less supported plugins that haven't passed the rigorous quality testing we expect, or are still missing documentation and/or unit tests
contains a set of codecs plugins based on libav (formerly gst-ffmpeg)
