Driver Options
General
Some features of the driver can be controlled by setting driver options. Each option is represented by a single bit, thus several options can be combined using binary OR operator. Options should be set with the help of function SetDriverOptions or SetDriverLong (keys 0 and 1).
If you set or clear an option make sure to call GetDriverLong (keys 0 and 1) to get current options, then use binary operations to set or clear appropriate bit.
Please note to set the Options before the call of startCapture !
