#4 wacaw fails on newer MacBookAirs

[Matthew Hutchinson]

For some reason, wacaw fails on the latest MacBookAir with FaceTime HD camera. I have tested this on multiple MacBook Airs.

Debugging a little with the source in Xcode I figure it must be some problem with permissions or the Quicktime Library and the newer hardware. Here is the output after building and running with verbose and the list-devices arg set;

verbose flag is set
DVFreeThread - CFMachPortCreateWithPort hack = 0x2e71750, fPowerNotifyPort= 0x2e71880
SGNewChannel failed for VideoMediaType (-9405).
SGSetChannelBounds failed.
SGSetChannelUsage failed.
SGGetChannelDeviceList failed (-2147450879).
The list is empty.

The 9405 error code maps to; couldntGetRequiredComponent

I have no other video devices connected and the machine is freshly built from the latest (and up to date) Mountain Lion.

The details of my Mac are below, Any help would be greatly appreciated; we are hoping to use wacaw in this project; https://github.com/mroth/lolcommits (in this release https://github.com/mroth/lolcommits/pull/114)
