Use the Wowza Streaming Engine™ media server software ServerListenerStartupStreamsMonitor server listener to monitor a live application's content folder for added and deleted .sdp and .stream files. When a new file is detected, the stream manager starts the stream. When a file is removed, the stream manager stops the stream. This article describes the configuration.
Edit [install-dir]/conf/Server.xml and make the following changes:
- Add the following <ServerListener> to the <ServerListeners> list:
<ServerListener> <BaseClass>com.wowza.wms.serverlistener.ServerListenerStartupStreamsMonitor</BaseClass> </ServerListener>
- Add the following properties to the <Properties> container at the bottom of the file:
<!-- Pipe (|) delimited list of application names for which to monitor: [vhost-name]:[application-name]/[app-instance] --> <!-- This can be shorted to [application-name] assuming using _defaultVHost_ and _definst_ as the vhost and application instance names --> <Property> <Name>startupStreamsMonitorApplicationList</Name> <Value>live1|live2</Value> </Property> <Property> <Name>startupStreamsMonitorStreamPrefix</Name> <Value>mp4</Value> </Property> <!-- MediaCaster type. Valid values are: rtp, rtp-record, shoutcast, shoutcast-record, liverepeater --> <Property> <Name>startupStreamsMonitorMediaCasterType</Name> <Value>rtp</Value> </Property> <!-- Pipe (|) delimited list of file extensions for which to search --> <Property> <Name>startupStreamsMonitorExtensionFilter</Name> <Value>.stream|.sdp</Value> </Property> <!-- The following property is only available in Wowza Streaming Engine 4.1.1 or later --> <!-- Enable the detection of modified files. If enabled, affected streams will be stopped and restarted when modifications are detected.--> <Property> <Name>startupStreamsMonitorFileModification</Name> <Value>true</Value> </Property>
Note: Modify the properties as needed for your streaming setup.
Next, edit [install-dir]/conf/[application-name]/Application.xml and make the following changes:
- Create a non-shared content folder for your application by setting the Streams/StorageDir property as follows:
<StorageDir>${com.wowza.wms.context.VHostConfigHome}/applications/${com.wowza.wms.context.Application}/content</StorageDir>
- Add the following properties to the <Properties> container at the bottom of the Application.xml file; be sure to get the correct <Properties> container as there are several in the file:
<Property> <Name>startupStreamsMonitorStreamPrefix</Name> <Value>mp4</Value> </Property> <!-- MediaCaster type. Valid values are: rtp, rtp-record, shoutcast, shoutcast-record, liverepeater --> <Property> <Name>startupStreamsMonitorMediaCasterType</Name> <Value>rtp</Value> </Property> <!-- Pipe delimited list of file extensions for which to search --> <Property> <Name>startupStreamsMonitorExtensionFilter</Name> <Value>.stream|.sdp</Value> </Property> <!-- The following property is only available in Wowza Streaming Engine 4.1.1 or later --> <!-- Enable the detection of modified files. If enabled, affected streams will be stopped and restarted when modifications are detected.--> <Property> <Name>startupStreamsMonitorFileModification</Name> <Value>true</Value> </Property>
Notes:- Modify the properties as needed for your streaming setup.
- The values specified here override the values specified in [install-dir]/conf/Server.xml.
- Modify the properties as needed for your streaming setup.
- Create the folder [install-dir]/applications/[application-name]/content. This folder will be monitored for new .sdp and .stream files.
- Start Wowza Streaming Engine.
