PROTOCOLS
Device
Defined in fuchsia.hardware.camera/camera.fidl
GetChannel
Note: this method obtains a channel to the capture device which communicates using a non-simple fidl interface. Once the system has been updated to support normal fidl protocols, this method can be replaced with the protocol itself. Additionally, while the camera stack is migrating from camera to camera2, two methods are available, corresponding to the two versions of the protocol.
