Warsaw Pakt 0.3.4

WarsawPakt is a software system for network-controlled media processing applications. It consists of a library for serialization of GObjects to XML, network components for publishing and accessing object spaces via multiple access methods (both in libpakt), a gstreamer module (gst) and an access shell program (pash). Its main purpose is to allow you to setup arbitrary gstreamer graphs on your local or a remote system, and modify its parameters while running.

The target audience of this manual are "accessors", people who want to access a pakt server via an XML access method, eg from Flash or some scripting language. This manual introduces you to basic pakt functionality and documents the various objects you can instantiate and control.

WarsawPakt consists of a bunch of components that make up its functionality. As an accessor, youre probably most interested in pgstd, and the classes and messages that libpakt provides for any pakt server.

libpakt

The pakt library (libpakt) provides basic pakt functionality: objects and functions for XML (de-)serialization, navigating around the object hierarchy, basic objects and GObject and GProperty wrappers, and networking classes. The accessible objects are documented in the p: namespace section (p: namespace) of the reference part of this manual.

paktd

The generic pakt daemon listens on specified ports for connections from pakt clients (like pash), and serves them with access to the server-side object space. The protocol is dependant on which modules are loaded.

modules

The generic pakt daemon (paktd) acts on objects defined by the loaded modules. Currently there is only one module:


gst

The GStreamer module (gst, libpaktgst.so) provides classes to interface pakt with GStreamer. The tags and their attributes are documented in gst: namespace

pash

pash, the pakt shell, is a commandline shell program that allows you to test, debug and experiment with a pakt server. It features readline-style tab expansion for the servers object space.
