(n.) Media Control Interface driver; a software component that directs the recording and playback of multimedia objects. The syntax requires an MCI command to “open” a device, give it instructions, and “close” it. For basic functions all MCI devices share a set of commands, such as “play” and “stop.” Microsoft originally defined 11 MCI devices that drivers control, including an undefined classification. See table below.
|MCI Device||Command Syntax|
|Audio CD player||MCI_DEVTYPE_CD_AUDIO|
|Digital audio tape||MCI_DEVTYPE_DAT|
|Video in a window||MCI_DEVTYPE_DIGITAL_VIDEO|
