    The StreamPublisher module in Wowza Streaming Engine™ software lets you schedule 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, where 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 will be replaced with the new one. If you set a schedule to begin in the past, the playlist will play immediately. ...

    The following code snippet enables you to modify the onMetaData data that's associated with an on demand stream. The class extends the MediaReaderFLV class and overrides the getMetaData method. It then calls the MediaReaderFLV getMetadata method, deserializes the data into an AMFDataList object, allows you to inject or modify the metadata, serializes the packet and returns it to the streamer.

    Code:
    package com.wowza.wms.plugin.test.mediareader;
    
    import java.util.*;

    The following is a quick example of how to use JSpeex with the Publisher API to send raw audio data to a Wowza media server.

    First, download a sample 16000Hz, stereo wav file and copy it to the [install-dir]/content folder: Extremists.wav

    Note: This file was created from the Extremists.flv file using the following ffmpeg command:
    Code:
    cd [install-dir]/content
    ffmpeg -i Extremists.flv -vn -ac 2 -ar 16000 Extremists.wav

    The following is a snippet of code for starting and stopping a stream using methods that are part of the IApplicationInstance interface. It is a couple of utility methods that can be used to simplify starting/stopping a stream:

    Code:
    IApplicationInstance.startMediaCasterStream(streamName, mediaCasterType);
    IApplicationInstance.stopMediaCasterStream(streamName)

    When using the rtp-live and rtp-live-record stream types, Native RTP and MPEG-TS streams are started and stopped on demand based on client's viewing the stream. The publishing process is started the first time a client tries to view a stream and stops 60 seconds after the last client has stopped viewing the stream. If you want to control when the stream is started and be sure it remains running, you can use the MediaCaster API to acquire and release the stream. The code looks like this:

    To start publishing/recording:
    Code:
    MediaCasterStreamMap mediaCasterMap = appInstance.getMediaCasterStreams();
    MediaCasterStreamItem mediaCasterItem = mediaCasterMap.acquire(streamName);
    ...

    The Dynamic Load Balancing AddOn enables you to redirect client connections across multiple Wowza media server installations when a single Wowza media server installation can't service all of the connections. A load-balancing configuration requires you to set up a Wowza "load balancer" server that directs client connections to additional Wowza "edge" servers that handle the connections. The edge servers periodically send load and status information to the load balancer so that it can track edge server load and availability. All communication between the edge servers and the load balancer is encrypted and signed. ...

    Live Stream Record, formerly a free AddOn, is incorporated into Wowza Media Server 3.5 as an API that gives you more control over recording live streams to video on demand files. This feature enables you to control the live stream recording process using a web-based user interface, HTTP URL queries, or programmatically. Powerful APIs are included to support splitting of in-process live streams into multiple on-demand MP4 (QuickTime container) files or FLV (Flash Video container) files, with the split points based on video duration, clock time, or file size. ...
