Sample setup for relaying a live broadcast

Setting Up a Relay Configuration File

You set up a relay by creating a relay conﬁguration ﬁle and copying it to the /etc/streaming

directory. The easiest way to create a relay conﬁguration ﬁle is to edit the sample ﬁle

provided with your streaming server software. The path and ﬁlename for the sample ﬁle is /

etc/streaming/streamingrelay.conf

A relay source and one or more relay destinations are part of a unit. Information about a relay

destination must immediately follow information about a relay source. You can have more

than one unit in a conﬁguration ﬁle.

The following example has one source and two destinations.

Example relay conﬁguration ﬁle:

relay_source "in_addr=192.168.1.1 src_addr=192.168.1.2 in_ports=5000

5002 5004 ttl=15"

relay_destination "dest_addr=192.168.1.3 out_addr=192.168.1.2

dest_ports=6980 6982 6984"

relay_destination "dest_addr=192.168.1.4 out_addr=192.168.1.2

dest_ports=10010 10012 10014 ttl=15"

A computer captures and encodes video and

audio using third-party broadcast software. The

encoded signal is sent to a Darwin Streaming

Server over an IP network.

A computer with Darwin Streaming Server relays

the signal to several destinations (using the IP

addresses and ports as specified in the

example file below).

Client computers tune

in to the broadcast.

The destination computers receive the

relayed signal and send it to client computers.

Source

(192.168.1.1)

Relay

(192.168.1.2)

Destination

(192.168.1.3)

Destination

(192.168.1.4)

Important Although the relay_source and relay_destination lines are each split over two

lines in the example, each must be on one line in your conﬁguration ﬁle.
