Relays
This section provides detailed information on setting up relays and working with relay
settings, using Streaming Server Admin.
Working With Relay Settings
Relays are used to accept a stream from one streaming server and send the stream on, or
“relay” it, to another streaming server. You set up relays using the Relay Settings pane in
Streaming Server Admin.
To see the Relay Settings pane, click Relay Settings.
The “Default Relay” relays all incoming broadcasts that are automatically announced to the
streaming server to one or more destinations. The default relay is set up just like any other
relay except there are no source settings. The default relay appears in the Relay Status pane
with the name ***qtssDefaultRelay***. The default relay can accept only forwarded media
streams using the RTSP announce protocol. UDP streams are not supported.
“Status: _ Enabled” instructs the server to relay any broadcast that is announced to it as soon
as the relay is saved.
“Relay Name” is used to identify the relay in Relay Settings and in the Relay Status pane.
“Source Hostname or IP Address” is the DNS hostname or IP address of the source
computer.
“Mount Point” is the name of the source that needs to be relayed. For example, if you want to
relay the incoming broadcast announced as “birthdayceleb.sdp,” the mount point is set to
birthdayceleb.sdp. You could also relay a source acquired by acting as a client and requesting
it from the source server. In this case, the mount point must be the URL of the resource
to acquire.
“Request incoming stream” directs the streaming server to send a request to the source
computer for the incoming stream before it gets relayed. This feature can be used to relay a
reflected live broadcast (from another server). It can also be used to request a stored file and
turn it into an outgoing live stream.
In any of these fields, “User Name/Password” is used if the source or destination computers
require automatic broadcasts to be authenticated with a name and password.
“Wait for announced stream(s)” 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. User Datagram Protocol (UDP) streams are not supported.
