Using Epiphan devices with 64-bit Macs

Epiphan has a range of devices for screen capture compatible with Quicktime. They work like regular Quicktime input devices, so you can use them with Podcast Capture. The Epiphan devices come with a 32-bit Kernel extension. If you are using an application that is walking the 64-bit path, you will not be able to use the Epiphan device as input within that application. You can see this with Quicktime Player. If you open Quicktime Player and you start a new recording, you will not be able to see the Epiphan device. If you now close Quicktime Player, select it in the Finder and open the info box (Command-i), you can check a button 'Open in 32-bit mode'. If you now open Quicktime Player again and start a new recording you will be able to see the Epiphan device.

Podcast Capture runs in 32-bit, so you won't have any trouble with that application using the Epiphan devices. If you want to bind the computer to the Podcast Producer server you have to be a little bit careful. Again, using the Podcast Capture application it should work because this app walks the 32-bit path. If you are trying to use the command line 'pcast' way, you will run into trouble. Using pcast, it will try to use the 64-bit frameworks, so it won't be able to see your Epiphan device. The solution is pretty simple, just use Podcast Capture to bind your camera.

If you find it important that Epiphan comes with a 64-bit version of their driver, please let them know at www.epiphan.com.
