Wirecast lets you broadcast to a specific machine. This is called "Unicast".
Unicast Steps
You must perform these steps to broadcast to a specific machine:
Configure The Broadcast Settings
See below for details on this.
Save the SDP file
After you are done configuring the screen, you need to save an SDP file.
This file is used by QuickTime client to know how the Broadcast is configured. Any time you change anything on this page, you need to re-create the SDP file (this includes changing the Encoder Preset).
To save the SDP file, select "Save SDP File" from the Action menu (Gear icon) on this page.
Give the SDP file to the viewer.
You need to send the SDP file to the viewer and have them open it on their machine with QuickTime Player.
Save the settings
Press the "Save" button to save your changes.
Start your broadcast
Select the "Start Broadcast" menu from the "Broadcast" Menu. Or, on Macintosh, you can Press the "Broadcast" button in the Toolbar area.
Configuring Broadcast Settings for Unicast
To do so, you need to select "Unicast" from the Destination popup as seen below:
Address
The domain name or IP address of the machine that you will unicast to.
Video Port
The Video port that you will broadcast to on the machine.
Audio Port
The Audio port that you will broadcast to on the machine.
Actions
When you have "Unicast" selected, the gear icon might have these actions:
Save SDP File
You must create an SDP file every time you change any option on this page (including the encoder preset).
The SDP file must be given to the user on the machine that will listen to your broadcast.
Your remote viewer should open the SDP file using QuickTime player.
Save Multi-stream Reference Movie [optionally present]
If you have other settings which use "Announce To QuickTime Streaming Server" then this menu option is available.
NOTE: Your Unicast or multicast information is not stored in this file. Only QuickTime Streaming Server streams are saved to this file.
