Release notes for GStreamer Good Plug-ins 0.10.24 "Taking Liberties"
|
||
|
||
|
||
|
||
The GStreamer team is proud to announce a new release
|
||
in the 0.10.x stable series of the
|
||
GStreamer Good 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.
|
||
|
||
|
||
|
||
"Such ingratitude. 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.
|
||
|
||
|
||
This module contains 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.
|
||
|
||
|
||
Other modules containing plug-ins are:
|
||
|
||
|
||
gst-plugins-base
|
||
contains a basic set of well-supported plug-ins
|
||
gst-plugins-ugly
|
||
contains a set of well-supported plug-ins, but might pose problems for
|
||
distributors
|
||
gst-plugins-bad
|
||
contains a set of less supported plug-ins that haven't passed the
|
||
rigorous quality testing we expect
|
||
|
||
|
||
|

||
|
||
Features of this release
|
||
|
||
* Use Orc (Optimized Inner Loops Runtime Compiler) for SIMD and
|
||
other optimisations, and remove liboil dependency. The main goal
|
||
for this release was to make the transition from liboil to liborc.
|
||
Performance improvements should not be expected and will be the
|
||
focus of future versions. liborc is an optional dependency for
|
||
the time being, to make it possible to test and develop the very
|
||
latest GStreamer versions on systems that don't have orc yet.
|
||
However, without orc slow unoptimised backup code will be used
|
||
for many performance critical code paths. Distributors are urged
|
||
to package and ship the latest version of liborc and compile
|
||
GStreamer modules with --enable-orc. Please do not distribute
|
||
GStreamer packages that are not orc enabled. More information on
|
||
the orc integration can be found in the docs/design/ directory.
