Notes
/Root/Application duplicateStreamsStreamNames String * A comma-separated list of stream names. Use the wildcard (*) character by itself to indicate all streams will be duplicated or to substitute for characters at the beginning or end of stream names. For example: *_720p,*_360p,*_240p,*_160p. (default: *)
/Root/Application duplicateStreamsTargetVHostName String _defaultVHost_ Name of target virtual host (VHost). (default: _defaultVHost_)
/Root/Application duplicateStreamsTargetAppName String live/_definst_ Name of the target application/application instance. (default: live/_definst_)
/Root/Application duplicateStreamsStreamNameSuffix String _dest Suffix to add to the stream name on the target application instance. Set to an empty string to have the same name published on the target. (default: _dest)

Usage


When a stream is published to the configured application, the stream name is checked against the values in the duplicateStreamsStreamNames property, and if a match is found, the stream is re-published to the application specified in duplicateStreamsTargetAppName. When the source stream is unpublished, the duplicate stream is also shut down.
