How to control which streams get packetized for HTTP streaming (PacketizerControl)

The ModulePacketizerControl module for Wowza Streaming Engine™ media server software controls which streams get packetized for HTTP streaming. It can be used with Wowza Transcoder or any time you don't need all of the streams to be packetized.

Note: You can also control which streams get packetized by using ModuleTranscoderControl and which streams get recorded for DVR playback by using ModuleDvrRecorderControl.

After enabling the module, you can adjust the default settings by adding the following properties to your application. See Configure properties for details.

/Root/Application packetizerControlSuffixes String * Can be an empty value, an "*", or a comma-separated list of name suffixes (for example: _source, _720p, _360p, _240p, _160p). The returned value is controlled by the settings of packetizerControlMatchAllow and packetizerControlNoMatchAllow. The suffixes are compared with the end of the stream name. (default: *)
/Root/Application packetizerControlMatchAllow Boolean true Controls the action after a match is found in the list of suffixes. If set to true, then the suffix list is is treated as a list of stream name suffixes that will be packetized. If set to false, then the suffix list is treated as a list of stream name suffixes that will not be packetized. If the list value is an *, then packetizerControlMatchAllow=true will be returned automatically. (default: true)
/Root/Application packetizerControlNoMatchAllow Boolean false Controls the action when no match can be found. If the list is empty, then packetizerControlNoMatchAllow=false will be returned automatically. (default: false)
