BPCVid.PrerollTime

The PrerollTime property specifies the time, in seconds, that a tape or other recording device should run before the multimedia stream for the Video control starts. Visual Basic syntax is shown.

object.PrerollTime [ = dTime ]

Parts

object

Object expression that resolves to a BPCVid or BPCDeviceBase object.

dTime

Double that specifies the number of seconds the tape should run before the stream starts.

Remarks

PrerollTime is not stored locally in the BPCVid object. Instead, it is passed to the corresponding property in the BPCDeviceBase object for the current input device. Your application should set preroll time using BPCVid.PrerollTime instead of the BPCDeviceBase.PrerollTime property. Otherwise, the Video control is not updated, and future behavior is undefined.
