Release notes for GStreamer Good Plugins 1.11.1

The GStreamer team is pleased to announce the first release of the unstable 1.11 release series. The 1.11 release series is adding new features on top of the 1.0, 1.2, 1.4, 1.6, 1.8 and 1.10 series and is part of the API and ABI-stable 1.x release series of the GStreamer multimedia framework. The unstable 1.11 release series will lead to the stable 1.12 release series in the next weeks. Any newly added API can still change until that point.

Full release notes will be provided at some point during the 1.11 release cycle, highlighting all the new features, bugfixes, performance optimizations and other important changes.

Binaries for Android, iOS, Mac OS X and Windows will be provided in the next days.

"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)
