Episode 022 - Broadcasting on Ustream.com & PGP Whole Disk Encryption
05/01/09 22:56
In this episode I was playing around and trying out live broadcasting via ustream, so the first half of the show I talk about what I am doing and the applications I use to broadcast.
First I created an account at http://www.ustream.com and set up all the data for my "show." I then downloaded an application called Camtwist - found at http://www.allocinit.com/index.php?title=CamTwist. This free application allows you to have multiple video inputs and have effects applied to them real time - then it allows this video to be put out as a single video feed and shows up as a video source in OSX, just like iSight or a firewire video camera.
Next I snagged an application called Wiretap anywhere from Ambrosia Studios found here: http://www.ambrosiasw.com/utilities/wta/ this application does somewhat the same thing as camtwist but with audio. This application allows you to have multiple audio inputs, combine them together and create a single audio "output" that can be selected in various OSX applications as an audio source.
This is not required to broadcast on ustream, but if you want the viewers to hear application sounds and you talking you will need an application like this. I used this application specifically for the audio output of garageband and my Blue Snowball microphone so that viewers can hear me talk and listen to the garageband output.
After I've set up my video and audio source I went back to ustream and logged in, then clicked the "Broadcast Now" button, and clicked OK on the security prompt to allow the website to use my camera and audio source. That's it - I'm now broadcasting live.
One thing I did discover - there is a delay, from 5-30 seconds is what I observed.
I also talk about PGP whole disk encryption for the mac and why I purchased it. This application provides whole disk encryption security. When booting you first have to type in a pass-phrase in order to allow the OS to boot. If someone were to steal the laptop - the data is safe because the entire disk is encrypted.
