Configuration

How to configure Dynamic Stream Server (DSS)

You'll find the default settings for DSS at dss/global.conf. Do not change this file directly for it may be updated. Instead, create another file local.conf in the same directory and add the sections and variables you want to replace.

Here is a description of the section and variables on those files.

All data types are explained at: Data Types for Configuration Files. Some of tem may also contain subtypes.

Unless explicitly stated, all options are available and unchanged since version 0.5.
