After all the times I've saved your life." + +A collection of plug-ins you'd want to have right next to you on the +battlefield. Shooting sharp and making no mistakes, these plug-ins 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 plug-in 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. + + THE UGLY + + --- "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. + + THE BAD + + --- "That an accusation?" + +No perfectly groomed moustache or any amount of fine clothing is going to +cover up the truth - these plug-ins are Bad with a capital B. +They look fine on the outside, and might even appear to get the job done, but +at the end of the day they're a black sheep.

Also, distributors have brought up issues about the legal status +of some of the plug-ins we ship. To remedy this, we've divided the previous +set of available plug-ins into four modules: + +- gst-plugins-base: a small and fixed set of plug-ins, covering a wide range + of possible types of elements; these are continuously kept up-to-date + with any core changes during the development series. + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + - These elements come with examples, documentation, and regression tests. + +- gst-plugins-good: a set of plug-ins that we consider to have good quality + code, correct functionality, our preferred license (LGPL for the plug-in + code, LGPL or LGPL-compatible for the supporting library). + + - We believe distributors can safely ship these plug-ins. + - People writing elements should base their code on these elements. + +- gst-plugins-ugly: 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. + - People writing elements should base their code on these elements. + +- gst-plugins-bad: a set of plug-ins that aren't up to par compared to the + rest. They might be close to being good quality, but they're missing + something - be it a good code review, some documentation, a set of tests, + a real live maintainer, or some actual wide use. + If the blanks are filled in they might be upgraded to become part of + either gst-plugins-good or gst-plugins-ugly, depending on the other factors. + + - If the plug-ins break, you can't complain - instead, you can fix the + problem and send us a patch, or bribe someone into fixing them for you. + - New contributors can start here for things to work on. + +INSTALLING FROM PACKAGES +------------------------ +You should always prefer installing from packages first.
