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

"That an accusation?"

No perfectly groomed moustache or any amount of fine clothing is going to cover up the truth - these plugins 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. Without a golden-haired angel to watch over them, they'll probably land in an unmarked grave at the final showdown.

Don't bug us about their quality - exercise your Free Software rights, patch up the offender and send us the patch on the fastest steed you can steal from the Confederates. Because you see, in this world, there's two kinds of people, my friend: those with loaded guns and those who dig. You dig.

This module contains a set of plugins 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 plugins 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.

Other modules containing plugins are:

contains a basic set of well-supported plugins
contains a set of well-supported plugins under our preferred license
contains a set of well-supported plugins, but might pose problems for distributors
contains a set of codecs plugins based on libav (formerly gst-ffmpeg)
