Attributes

Remarks

This method is called when the camera device has started capturing the initial input image of the device-specific extension post-process request.

This callback is invoked right as the capture of a frame begins, so it is the most appropriate time for playing a shutter sound, or triggering UI indicators of capture.

The request that is being used for this capture is provided, along with the actual timestamp for the start of exposure.

The default implementation of this method does nothing.
