Public Attributes
uint64_t	device_delivered = 0
	Number of frames delivered by the device.
uint64_t	device_transmission_error = 0
	Number of frames dropped because of transmission errors, e.g. unrecoverable packet loss.

uint64_t	transform_delivered = 0
	Number of frames delivered by the transform element.
uint64_t	transform_underrun = 0
	Number of frames dropped by the transform element, because there was no free image buffer available.
uint64_t	sink_delivered = 0
	Number of frames processed by the sink.
uint64_t	sink_underrun = 0
