Release notes for GStreamer Ugly Plug-ins 0.10.17 "Raised by Wolves"

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.

"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
