GStreamer 1.0 series

Starring

GSTREAMER

The core around which all other modules revolve. Base functionality and libraries, some essential elements, documentation, and testing.

BASE

A well-groomed and well-maintained collection of GStreamer plug-ins and elements, spanning the range of possible types of elements one would want to write for GStreamer.

And introducing, for the first time ever, on the development screen …

THE GOOD

— “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.

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. 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.

The Lowdown

— “I’ve never seen so many plug-ins wasted so badly.”

GStreamer Plug-ins has grown so big that it’s hard to separate the wheat from the chaff. 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:

PLATFORMS

INSTALLING FROM PACKAGES

You should always prefer installing from packages first. GStreamer is well-maintained for a number of distributions, including Fedora, Debian, Ubuntu, Mandrake, Arch Linux, Gentoo, …

Only in cases where you:

should you choose to build from source tarballs or git.

PLUG-IN DEPENDENCIES AND LICENSES

GStreamer is developed under the terms of the LGPL (see COPYING file for details). Some of our plug-ins however rely on libraries which are available under other licenses. This means that if you are distributing an application which has a non-GPL compatible license (for instance a closed-source application) with GStreamer, you have to make sure not to distribute GPL-linked plug-ins.

When using GPL-linked plug-ins, GStreamer is for all practical reasons under the GPL itself.

HISTORY

The fundamental design comes from the video pipeline at Oregon Graduate Institute, as well as some ideas from DirectMedia. It’s based on plug-ins that will provide the various codec and other functionality. The interface hopefully is generic enough for various companies (ahem, Apple) to release binary codecs for Linux, until such time as they get a clue and release the source.
