The StreamPublisher module for Wowza Streaming Engine™ media server software lets you use a server listener and application module to create a schedule of streams and playlists. Using television as an analogy, a stream is a channel and a playlist is a program with one or more video segments. A schedule can have as many streams (channels) as you want, with as many playlists (programs) as you want, and each playlist can be scheduled to play on a stream at a certain time. If a playlist is scheduled to start on a stream while another playlist is running, the existing playlist is replaced with the new one. If you set a schedule to begin in the past, the playlist plays immediately.


Wowza Streaming Engine 4.0.0 or later is required.


You can create a schedule with server listener and application module methods, either together or separately, depending on your needs.

You can use the ServerListenerStreamPublisher server listener to load a set of scheduled streams on a single application when the media server starts. This procedure keeps the streams running until the server is shut down. If you use this process, the schedule can't be reloaded by using just the server listener.

You can use the ModuleStreamPublisher application module on any application to load a set of scheduled streams on that application when the application starts and unload the streams when the application is shut down. The schedule can be reloaded by modifying the SMIL file for the application and then reloading it. The module can provide the reload functionality to the schedule that's configured in the server listener. It can also be used on its own, in separate applications, to provide separate schedules for each application. Each application that runs a schedule must have a live stream type.

To use the included ModuleLoopUntilLive application module to loop pre-roll video around a live stream, at least one server-side stream must be configured on the Streaming Engine live application.
