2 Release notes for GStreamer Good Plug-ins 0.10.31 "Faster"
6 The GStreamer team is proud to announce a new release
7 in the 0.10.x stable series of the
8 GStreamer Good Plug-ins.
11 The 0.10.x series is a stable series targeted at end users.
15 "Such ingratitude. After all the times I've saved your life."
18 A collection of plug-ins you'd want to have right next to you on the
19 battlefield. Shooting sharp and making no mistakes, these plug-ins have it
20 all: good looks, good code, and good licensing. Documented and dressed up
21 in tests. If you're looking for a role model to base your own plug-in on,
25 If you find a plot hole or a badly lip-synced line of code in them,
26 let us know - it is a matter of honour for us to ensure Blondie doesn't look
27 like he's been walking 100 miles through the desert without water.
30 This module contains a set of plug-ins that we consider to have good quality
31 code, correct functionality, our preferred license (LGPL for the plug-in
32 code, LGPL or LGPL-compatible for the supporting library).
33 We believe distributors can safely ship these plug-ins.
34 People writing elements should base their code on these elements.
37 Other modules containing plug-ins are:
41 contains a basic set of well-supported plug-ins
43 contains a set of well-supported plug-ins, but might pose problems for
46 contains a set of less supported plug-ins that haven't passed the
47 rigorous quality testing we expect
