     mvSetVideoDisplay,	mvGetVideoDisplay - Set/get movie video	display	mode.

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/moviefile.h>
     #include <dmedia/movieplay.h>

     void mvSetVideoDisplay(MVid movieId, MVvideoDisplay mode);

     MVvideoDisplay mvGetVideoDisplay(MVid movieId);

DESCRIPTION    [Toc]    [Back]

     The Movie Playback	Library	supports 3 video display modes that specify
     how movies	of non-standard	sizes should be	displayed on video devices
     (e.g. when	they are bound to MV_PORT_VIDEO).

     MV_VIDEO_DISPLAY_UPPER_LEFT    [Toc]    [Back]
	      -	movie is in the	upper left corner of the video
     MV_VIDEO_DISPLAY_CENTER
	      -	movie is centered in the video
     MV_VIDEO_DISPLAY_SCALE_TO_FIT,
	      -	display	is scaled to fit the natural video size

     Note that when the	movie is the natural size of
     the video path, the three modes are equivalent.

     mvGetPlayLoopMode(3dm) returns the	current	video display mode
     for the specified movie.

     The default display mode is MV_VIDEO_DISPLAY_CENTER.

     You may invoke either of these calls on a movie regardless	of
     whether or	not the	movie is currently playing.

NOTES    [Toc]    [Back]

     The video display mode has	no effect on how the movie is displayed	on the
     graphics screen.

     The scale implied by MV_VIDEO_DISPLAY_SCALE_TO_FIT	is done	using an
     unspecified algorithm.  The natural size is dependent on the current
     VL_TIMING of the video path being used.
