Release notes for GStreamer Ugly Plug-ins 0.10.11 "Their swords and their knives"

The GStreamer team is proud to announce a new release in the 0.10.x stable series of the GStreamer Ugly 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.

"When you have to shoot, shoot. Don't talk."

There are times when the world needs a color between black and white. Quality code to match the good's, but two-timing, backstabbing and ready to sell your freedom down the river. These plug-ins might have a patent noose around their neck, or a lock-up license, or any other problem that makes you think twice about shipping them.

We don't call them ugly because we like them less. Does a mother love her son less because he's not as pretty as the other ones ? No - she commends him on his great personality. These plug-ins are the life of the party. And we'll still step in and set them straight if you report any unacceptable behaviour - because there are two kinds of people in the world, my friend: those with a rope around their neck and the people who do the cutting.

This module contains a set of plug-ins that have good quality and correct functionality, but distributing them might pose problems. The license on either the plug-ins or the supporting libraries might not be how we'd like. The code might be widely known to present patent problems. Distributors should check if they want/can ship these plug-ins.

Other modules containing plug-ins are:

contains a basic set of well-supported plug-ins
contains a set of well-supported plug-ins under our preferred license
contains a set of less supported plug-ins that haven't passed the rigorous quality testing we expect
