Functions
NvDsUserMeta *	nvds_set_input_system_timestamp (GstBuffer *buffer, gchar *element_name)
	Sets the system timestamp when the gst buffer arrives at the input of the component. More...
gboolean	nvds_set_output_system_timestamp (GstBuffer *buffer, gchar *element_name)
	Sets the system timestamp when the gst buffer is pushed to the downstream component. More...
guint	nvds_measure_buffer_latency (GstBuffer *buf, NvDsFrameLatencyInfo *latency_info)
