NAME    [Toc]    [Back]

     mvSetPlayEveryFrame, mvGetPlayEveryFrame -	Make movies play against time
     base, or without dropping frames

SYNOPSIS    [Toc]    [Back]

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


     void mvSetPlayEveryFrame(MVid movieid, DMboolean sync);

     DMboolean mvGetPlayEveryFrame(MVid	movieid);

DESCRIPTION    [Toc]    [Back]

     mvSetPlayEveryFrame(3dm) allows you to decide whether a movie should play
     in	real-time against a clock base,	or should play back all	frames.

     To	play back every	frame in sequence without dropping intervening frames,
     call mvSetPlayEveryFrame with a value of DM_TRUE for the sync parameter.

     To	play back movies at the	current	speed, dropping	frames if necessary to
     keep up with the movie's time base, call mvSetPlayEveryFrame(3dm) with a
     value of DM_FALSE for the sync parameter.	The current speed is the
     natural frame rate	for the	movie, as specified in the movie file,
     multiplied	by the current play speed.  To change the current play speed,
     use mvSetPlaySpeed(3dm).

     When the Movie Playback Library is	set to play back every frame, it
     automatically suspends audio playback.  Additionally, you will not
     receive MV_EVENT_SLOW_PLAY	events when a movie is set to play back	every
     frame.

     The default playback mode is always DM_FALSE.

     mvGetPlayEveryFrame(3dm) returns the current setting of
     mvSetPlayEveryFrame(3dm) for the specified	movie.

     You may only call these functions for a specified movie while it is bound
     to	a window (see mvBindOpenGLWindow(3dm)).

NOTES    [Toc]    [Back]

     In	IRIX 6.3 and 6.4, when the Movie Playback Library was set to play back
     every frame, it did NOT suspect audio playback.  The Movie	Playback
     Library played all	audio and video	unsynchronized instead.	To enable this
     previously	undocumented feature, set the MV_PLAYEVERY_WITH_AUDIO
     environment variable.
