This event is fired each time a frame is dropped during the video acquisition.
Private Sub objActiveDcam_FrameDropped() [C/C++]
This VB example uses the FrameDropped event to generate a sound signal:
Private Sub ActiveDcam1_FrameDropped()
The FrameDropped event is raised if a video FIFO overflow occurs during the acquisition of a frame resulting in a frame drop. The most common reasons for this are low bandwidth (several cameras connected to the 1394 board) or CPU overload.
