MediaCoder maintains a unified parameter tree whose leaves (parameter values) can be altered through the application GUI, a web-based tree view, user interfaces for specific devices (e.g. PSP, iPhone) and conforming HTTP requests. It maps the parameter tree into command line options or calling parameters for various codecs and tools.
