In we will move on to the examples. Since GStreamer uses GLib 2.0, the reader is assumed to understand the basics of the GObject object model. For a gentle introduction to this system, you may wish to read the GTK+ Tutorial or Eric Harlow's book Developing Linux Applications with GTK+ and GDK. &INTRO; &MOTIVATION; &GOALS; We will first describe the basics of GStreamer programming by introducing the different objects needed to create a media pipeline. We will use a visual representation of these objects so that we can visualize the more complex pipelines you will learn to build later on. &INIT; &ELEMENTS; &PLUGINS; &PADS; &LINKS; &BINS; &BUFFERS; &STATES; With the basic concepts out of the way, you're ready to start building a full-scale GStreamer application. We assume the reader is familiar with GTK+/GNOME programming. &HELLOWORLD; &FACTORIES; In this part we will cover the more advanced features of GStreamer. With the basics you learned in the prevous part you should be able to create a 'simple' pipeline. If you want more control over the media types and the pipeline you should use the more low-level features of GStreamer. &THREADS; &QUEUES; &COTHREADS; &SCHEDULERS; &CLOCKS; &DYNAMIC; &TYPEDETECTION; &AUTOPLUGGING; &HELLOWORLD2; &DPARAMS; GStreamer has the possibility to serialize the pipelines you create using an XML format. You can load a previously created pipeline by loading the XML file. &XML; GStreamer comes prepackaged with a few programs, and some useful debugging options. &DEBUGGING; &PROGRAMS; &COMPONENTS; &GNOME; "ES;
