Release notes for GStreamer Good Plugins 1.12.3

The GStreamer team is proud to announce the third bugfix release in the stable 1.12 release series of your favourite cross-platform multimedia framework!

This release only contains bugfixes and it is safe to update from 1.12.x. For a full list of bugfixes see Bugzilla.

See /releases/1.12/ for the full release notes.

"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)
