June 31, 2012. Fix updated to use Adobe AIR 3.1 instead of 2.7.1. AIR 3.1 does not have the video distortion issue, and allows you to select from multiple webcams.
Or upgrade to Sparkbooth 3.5 or later which has controls to adjust the distortion.
With Mac computers, the Adobe AIR 3.2 update changes the proportion of the video for Sparkbooth. For this reason, I do not recommend installing Adobe AIR 3.2. If you have already installed the update and are seeing the changed video proportions, here is what you need to do:
Close Sparkbooth if it is open
Uninstall Adobe AIR 3.2. Run the Adobe AIR Uninstall in Applications > Utilities folder.
Adobe has just released an Adobe AIR update for Mac only that fixes the camera detection issue. Here is what Adobe said:
Today we posted a very minor update for the Adobe AIR 2.5.1 runtime that addresses a known issue related to interacting with a system’s camera on Mac systems. This is a desktop only release for the Mac; Windows and Linux users will not be impacted by this issue and will therefore not be prompted to update.
The build number for the Mac update is AIR 184.108.40.20650. We recommend that users update to the latest version of Adobe AIR.
