Why isn't my Mac webcam reporting supported video formats when I request Silverlight 4?

Question

I am testing Silverlight 4 code to connect to webcams to capture video and audio. Everything works fine on a PC, but on Mac computers it seems that when you request a webcam for supported video formats, the data does not return when using the VideoCaptureDevice.SupportedFormats call. I tried this using both an external webcam and an integrated iSight camera.

When viewing Silverlight settings on a Mac, I see a webcam and it shows a video, so I know that it is connected and working correctly.

I should mention that a similar request (AudioCaptureDevice.SupportedFormats) for audio formats works.

Does anyone know what might cause this?

Well, that’s awkward. MSDN shows that OSX will always return this as empty, now turned off to get around this ...
