+
+ Triggered immediately when the reception of a
+ frame has begun. This event has a
+ &v4l2-event-frame-sync; associated with it.
+
+ If the hardware needs to be stopped in the case of a
+ buffer underrun it might not be able to generate this event.
+ In such cases the frame_sequence
+ field in &v4l2-event-frame-sync; will not be incremented. This
+ causes two consecutive frame sequence numbers to have n times
+ frame interval in between them.
