format  void MPG_WnSetOutputMode (MpgWn mpgwn, Sint32 omode, void * buf)
 Input  mpgwn: MPEG window
:  omode: Output mode (MPG_NOCHG: No change)
:  buf: Transfer area (MPG_NOCHG: No change)
 Output  None
 Function value  None
 Function  Set the MPEG window output method.
 
 (1) Output mode
 
 MPG_OMODE_DRCT: Direct output to VDP2
 MPG_OMODE_HOST: Output by transfer to the host area 
 
 
When the host transfer mode is specified, executing the MPG_WnTrans function will cause the buf
It will be transferred to the zone. If the transfer function is not registered, an area on the B bus is specified for buf.
      Have to.

  format  void MPG_WnDisp (MpgWn mpgwn, Bool dsw)
 Input  mpgwn: MPEG window
:  dsw: Display switch (ON / OFF)
 Output  None
 Function value  None
 Function  Set whether to display the MPEG window. Direct output to VDP2 and host
  cannot be transferred at the same time. Output window to VDP2 has priority, so to VDP2
When the output window of   is being displayed, the output window for host transfer is displayed.
 Not .
 Remarks  (a) Do not turn on more than one VDP2 output window. 

  format  void MPG_WnSetLoc (MpgWn mpgwn, Uint32 dzx, Uint32 dzy)
 Input  mpgwn: MPEG window
:  dzx: X coordinate of the display reference position (pixel unit)
:  dzy: Y coordinate (pixel unit) of display reference position
 Output  None
 Function value  None
 Function  Sets the display reference position of the display window. When the window is displayed
The display position will be changed immediately when .
