Adding the server listener

To enable the server listener, add the following server listener definition to your server in Wowza Streaming Engine Manager. See Configure server listeners for details.

Base Class

Adding the HTTP provider

To configure the HTTP provider:

  1. In a text editor, open [install-dir]/conf/VHost.xml and navigate to the Admin Hostport section in the file:
    <!-- Admin HostPort -->
  2. In the <HostPort>/<HTTPProviders> container, insert the BlacklistStreams HTTP provider before the final <HTTPProvider> entry in the container:
  3. Save and close the VHost.xml file, and then restart the media server to apply the changes.


The following properties can be set for the server listener. See Configure properties for details.

/Root/Server blacklistStreamsConfigPath String /usr/local/WowzaStreamingEngine/conf/blacklist.txt The full path to the blacklist file. (default: [install-dir]/conf/blacklist.txt)
/Root/Server blacklistStreamsDebugLog Boolean true Enables extra logging. (default: false)


To blacklist a stream:

  1. Start your Wowza Streaming Engine media server, and then open the following URL to the Stream Blacklists page in a web browser:
    Where [wowza-ip-address] is the IP address of the Wowza media server.
  2. When prompted, enter the credentials that you use to sign in to Wowza Streaming Engine Manager.
  3. Publish your first stream, and then in the Stream Blacklists page, click Check for new streams. Your new stream will be displayed in the Published Streams list.
  4. Click the Blacklist link next to the published stream to add that stream to the blacklist. This will also stop the stream. Any subsequent attempts to publish to that [app-name]/[app-instance]/[stream-name] sequence are rejected until you remove the stream from the blacklist.
