Description

TMediaPlayer controls devices that provide a Media Control Interface (MCI) driver.

The TMediaPlayer component includes a set of buttons (Play, Stop, Eject, and so on) that control a multimedia device such as a CD-ROM drive, MIDI sequencer, or VCR. A multimedia device may be hardware or software.

The media player component contains of multiple buttons. These buttons can be clicked with the mouse, but are not separate objects or button components.

The multimedia device is played, paused, stopped, and so on when the user clicks the corresponding button on the TMediaPlayer component. The device can also be controlled by the control methods that correspond to the buttons (Play, Pause, Stop, Next, Previous, Step, Back, StartRecording, and Eject).

The type of multimedia device (such as dtWaveAudio or dtVideodisc) is specified by the DeviceType property. If the device stores its media in a file, the name of the media file is specified by the FileName property. If DeviceType is dtAutoSelect, the media player attempts to determine the type of device from the extension of the file specified by FileName.

To have the media player attempt to open the device specified by DeviceType automatically when the media player component is created at runtime, set the AutoOpen property to true.
