Media Player (both the 16-bit MPLAYER.EXE and the 32-bit MPLAY32.EXE)
supports the following command-line syntax:
MPLAYER /play /close /embedding file
All of the command-line switches and the file name are optional. Their
meanings are as follows:
/play Play file right away.
/close Close after playing (only valid with /play).
/embedding Run as an OLE server.
file The file or device to open.
This information was inadvertently omitted from the Windows documentation.
In Windows 95 and Windows NT 3.5 and higher, the Media Player also supports
the following switch:
/open Open the file if specified; otherwise, show the File Open
dialog.
In addition, the following switches can be used to ensure that the
specified file is of a particular type:
/AVI The file must be a Video for Windows (.AVI) file.
/MID The file must be a MIDI (.MID) file.
/WAV The file must be a Wave Audio (.WAV) file.
