Streaming a webcast using Ustream.tv
The following instructions ( adapted from this blog post by Alec Couros ) will guide you through the process of setting up your computer as well as streaming an audio production using Ustream or other streaming media site. Install Camtwist, Linein and Soundflower. and the Voice over the Interent Program (VOIP) Skype. All these programs are available for free on the Internet. The next step is to setup your preferences for your computer for each of the 4 applications.
Click the Apple icon to activate system preferences
Set the audio input and output as Soundflower(2ch) You can leave the ringing setup as the default setting.
Disable (uncheck) the camera in your Skype preferences. The camera may be used for broadcasting in Ustream.
Set your input to Headset and output to Soundflower (2ch)
You will be activating this button to channel your audio through your headset and to the Broadcast. When it is unselected you will not be able to hear anything. It is a common mistake to forget to activate Linein by not selecting the Pass Thru button.
Select your Audio device for Soundflower (2ch). In this case, it is the Logitech USB Headset.
If you have not set up an account with ustream, do so now. Type the name of your show into the "Create New Show" box and click "Create". Once the information is entered, click "Broadcast Now" to start broadcasting.
A broadcast window will appear and request permission to detect your webcam or camera.
Video source is set as your web camera. In this case with the USB built in iSight the source is USB video, Audio Source is Soundflower 2(ch)
Make sure that the Linein setting for Pass thru is activated
When you click on stop the recording, you will be given the option to play delete or save your recording. To save your recording, click on save.
If you want to go beyond talking heads on Ustream, Camtwist allows you to change the virtual video device so that you can broadcast parts of your screen, or broadcast videos previously saved to your computer. This is a great tool that has a lot of potential for conferencing sessions. To play the audio of a movie, playing iTunes or recorded mp3 audio while streaming, use Camtwist and set the "General" preferences as Soundflower (2ch) For more information go to this tutorial.
