Overview
|
|
Introduction
|
|
(creating multimedia apps)
|
|
(pipeline/plugin based)
|
|
|
|
Motivation
|
|
(multitude of duplicate code)
|
|
(mostly focused on one goal)
|
|
(reinvent plugin mechanisms)
|
|
(network transparency?)
|
|
(catch up with Windows(tm) world)
|
|
|
|
Goals
|
|
(clean and powerfull)
|
|
(building graphs)
|
|
(building plugins)
|
|
(object oriented)
|
|
(using GTK+ object model)
|
|
(extensible)
|
|
(alow binary only plugins)
|
|
(alow high performance)
|
|
(HW acceleration)
|
|
(efficient memory use)
|
|
(kernel buffers etc..)
|
|
|
|
Basic concepts
|
|
elements
|
|
(what is it)
|
|
(types) sink, src, filter
|
|
(have pads)
|
|
connecting elements
|
|
bin
|
|
(can contain elements)
|
|
pipeline (a complete graph)
|
|
thread (theaded operation)
|
|
buffers
|
|
(pass between elements)
|
|
(contains data)
|
|
(can cary metadata)
|
|
(use refcounting)
|
|
element states
|
|
(null)
|
|
(ready)
|
|
(paused)
|
|
(playing)
