discoverySessionWithDeviceTypes static method
Creates a discovery session for finding devices with the specified criteria.
deviceTypes
: A list of device types to search for, such as
CaptureDeviceType.builtInMicrophone and
CaptureDeviceType.builtInWideAngleCamera. This list must contain at
least one valid CaptureDeviceType value.
mediaType
: The media type to capture, such as MediaType.audio. Pass
null
to search for devices regardless of supported media types.
position
: The position of capture device to search for, relative to
system hardware (front- or back-facing). See CaptureDevicePosition. Pass
CaptureDevicePosition.unspecified to search for devices regardless of
position.
After creating a device discovery session, read its devices array to examine matching devices and choose one for capture.
