Opening the camera app on the emulator, I am able to see the preview screen, but when I click on the Camera Recording button, the preview stops, and I see this error in the console. Looks like an invalid argument. The repro is just building / running the emulator, and the camera app within it.

Hi Mike, Is there any progess on this issue?

But camera recording button works for me, although I always get still image and the sound quality is terrible.
