Create a Media Server
The following steps will create a new media server on the Content Server with support for live and on demand streaming through QuickTime Streaming Server. If you only require support for one type of streaming, follow the steps as applicable to create a live streaming-only or on demand-only media server.
Step 1 From the Management tab, go to Recording setup > Media server configurations .
Step 2 Click Add QuickTime or D arwin Streaming Server to create a new QuickTime media server.
Step 3 Enter a name for your new media server, and check the type of streaming you want to support. You can check Support live unicast streaming, Support live multicast streaming , Support on Demand, or all three.
Step 4 If you checked Support live unicast streaming, do the following:
a. In the Unicast server address field, enter the IP address of the QuickTime Streaming Server in the Unicast server address field.
b. Enter a Streaming port range start value that is within the range set in Step 3 of “Configure for live unicast streaming”. This value must be an even number. The Content Server will use a range of 30 ports beginning with this port for streaming of up to two live simultaneous calls.
c. Enter the user credentials you have authorized to write to the QTSS in Step 6 of the “Configure for Live Unicast Streaming” section.
d. In most cases when setting up a new media server, it is recommended that you click Use default live URL.
Note You should choose to use alternate live URLs only if you know the live streaming URLs for the QuickTime Streaming Server require different path or filename information to that generated by the Content Server (for example, when live streaming to a CDN).
Step 5 If you checked Support live multicast streaming , do the following:
a. In the Multicast IP address field, enter the destination multicast IP address that the Content Server streams to. Your chosen multicast IP address must not conflict with any other multicast address in use in your network. Further considerations apply if you want to multicast over the public Internet. Contact your network administrator for more information.
b. In the Streaming port range start field, enter the first port number in the live streaming port range. The setting is between 10000 and 65000. This port number must be even.
c. In the TTL drop-down menu, choose the multicast time to live (TTL) threshold.
This value tells the network how far multicast packets should be allowed to travel across the network. The default threshold is LAN (TTL=32). The value "Subnet" (TTL=1) means that packets do not pass the first network router and should mean a multicast stream is viewable on any network, even those not enabled for multicast, where the client is on the same subnet as the Content Server.
The efficacy of higher values—LAN (TTL=32), WAN (64), Internet (128), Unrestricted (255)—depends on the network configuration.
Step 6 If you checked Support on demand , media needs to be moved from the Content Server to the QuickTime Streaming Server. The standard method for this is File Transfer Protocol (FTP). In the On demand settings section, click FTP movies to location and enter the required FTP server information:
a. In Server address , enter the FTP server IP address.
b. The default FTP port is 21.
c. If you leave the Directory field empty, the media will be placed in the root folder of the FTP server.
d. Ensure that the account used for the FTP user has write privileges to the FTP server.
e. In the On demand URLs section, it is recommended that you click Use default on demand URLs .
You should enter alternate on-demand URLs only if you know the streaming server requires a different path or filename information to that generated by the Content Server.
Step 7 Click Save .
Create a Template
Now that you have created a media server that supports streaming from a QuickTime Streaming Server, you need to use this media server in a Content Server template. Multiple templates can use the same media server.
Step 1 From the Management tab, go to Recording setup > Templates.
Step 2 Click Add template to create a new template.
Step 3 In the Name field, enter a name for your template.
Step 4 Check Viewable in the Content Server web interface .
Step 5 In the Outputs to view in the Content Server web interface section , click one of the viewing layouts.
Step 6 In the On demand section, do the following:
a. Click MPEG-4 for QuickTime from the formats available.
b. Click one or two options under Sizes ( Audio only , Small , Medium , or Large ).
Step 7 In the On demand media server settings for MPEG-4 for QuickTime, choose a media server that supports on-demand streaming from a QuickTime Streaming Server.
Step 8 Check Live stream if you would like the call to be available for live streaming. Ensure that the format for live streaming chosen from the drop-down menu is MPEG-4 for QuickTime .
Step 9 In the Live media server settings section, choose a media server that supports live streaming from QTSS.
Step 10 Click Save .
Create a Recording Alias
Now that you have a template for streaming from a QuickTime Streaming Server, you need to create a recording alias on the Content Server that uses this template. Multiple recording aliases can use the same template.
Step 1 From the Management tab, go to Recording setup > Recording aliases to add or edit a recording alias.
Step 2 Enter a name for your recording alias, and choose a Content Server template that supports streaming from QTSS.
Step 3 Click Save .
You have now configured the Content Server for streaming off QuickTime Streaming Server. Make a test call on the recording alias you have created to verify your configuration.
