Chapter 3 Managing Your QuickTime Streaming Server 31

5 Ask users to put their hinted QuickTime movies into the folder that was created in their

home directories (/<username>/Sites/Streaming).

To view a movie in a private movie directory, enter the URL:

rtsp://hostname.com/~user1/sample.mov

Note: To stream a live broadcast from a directory other than the media directory, you

need to create a qtaccess file. For more information, see the QuickTime Streaming

Server administrator’s guide available at developer.apple.com/darwin/.

Setting Up Relay Streams

You use relays to accept a stream from one streaming server and send the stream on,

or “relay” it, to another streaming server. Each relay comprises a source and one or

more destinations.

To set up a relay:

1 In the Settings pane of the QuickTime Streaming service, click Relays.

2 Click the Add (+) button next to the Relays list.

3 Enter a name for the relay in the Relay Name field.

4 Choose an option from the Relay Type pop-up menu.

The Relay Type defines the source for the relay. There are three different options for

Relay Type:

Request Incoming Stream directs the streaming server to send a request to the source

computer for the incoming stream before it gets relayed. You can use this feature to

relay a reflected live broadcast (from another server) or to request a stored file and turn

it into an outgoing live stream. Request Incoming Stream is commonly used with

unannounced UDP streams from QuickTime Broadcaster or other streaming encoders.

Unannounced UDP directs the server to relay streams on a specific IP address and port

numbers.

Announced UDP directs the server to wait for the incoming stream and then relay it.

Relays set to wait for announced streams can accept only media streams using the

RTSP announce protocol. Announced UDP is used with Automatic (Announced)

broadcasts from QuickTime Broadcaster or other streaming encoders that support the

RTSP announce protocol.

5 In case of Request Incoming Stream or Announced UDP, in the Source IP field, enter the

DNS hostname or IP address of the source computer.

6 In case of Request Incoming Stream or Announced UDP, in the Path text field, enter the

pathname to the stream.

7 In case of Request Incoming Stream or Announced UDP, if the source computer

requires automatic broadcasts to be authenticated, enter a user name and password.

8 Make sure Enable Relay is selected and click the Back button.
