Description

Using: OpenCV-2.4.0, Mac OS X 10.6

When using Quicktime (QtKit), available capture devices are found in CvCaptureCAM::startCaptureDevice using inputDevicesWithMediaType:QTMediaTypeVideo . However, DV video cameras have media type QTMediaTypeMuxed. This makes DV video cameras inaccessible.

Attached patch fixes the issue by appending input devices with media type QTMediaTypeMuxed.
