Introduction

This series of articles is intended to pick up where others leave off. The choice of subject matter has an emphasis on video, which PiTiVi hackers should find particularly relevant.

Intended Audience

I'm going to assume that the reader is very familiar with python, and has some basic knowledge about gst-python. In particular, Read the following material before continuing:

These articles are written in a tutorial format. You may also wish to refer to the official PyGST and GStreamer references. The C documentation is often more helpful than the PyGST documentation.

http://pygstdocs.berlios.de/
http://pygstdocs.berlios.de/pygst-tutorial/ (direct link to official tutorial)
http://gstreamer.freedesktop.org/data/doc/gstreamer/head/manual/html/index.html

This article is primarily about GStreamer and gnonlin, so I'm not going to spend a lot of time about explaining the basics of PyGTK or the GObject programming model. In particular, you should understand the GObject concepts of signals and properties.

How to Contact

This material is evolving, and I encourage readers to send feedback to. You can write me at brandon_lewis AT alum dot berkeley dot edu. I am also in #pitivi channel on the freenode irc network.

Running the Examples

The examples are intended to be run from the command line, and the meaning of the arguments varies from example to example. Most of the examples import at least demo.py, so you should save all the all examples into the same directory. At the moment I cannot upload files with a .py extension directly into the wiki, so you must manually copy and paste the example source into a text editor. Apologies for the inconvenience.
