The frame is captured from the position indicated by the StillTap property.

When capturing from the still pin, the capture happens when the user presses the hardware button for capturing the still image.
If there is not a hardware button or the user does not press it, the capture occurs after the timeout specified by the CaptureStillDelay property.
