NAME    [Toc]    [Back]

     mvGetTrackEnable, mvSetTrackEnable	- Enable/Disable a track

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/moviefile.h>

     DMstatus mvSetTrackEnable(	MVid track, DMboolean enable );
     DMboolean mvGetTrackEnable( MVid track );

DESCRIPTION    [Toc]    [Back]

     Each track	in a movie can be enabled or disabled.	Most functions that
     operate on	the movie as a whole take this flag into account.  Most	movie
     editing functions,	like mvDeleteMovieAtTime, take an argument that
     determines	whether	to operate on the whole	movie or only on the enabled
     tracks.  All rendering functions, like mvRenderMovieToOpenGL, only
     operate on	enabled	tracks.	 When a	track is created, it is	enabled	by
     default.

     mvSetTrackEnable

     This function sets	the enable flag	for the	track passed in	track.	If
     track is invalid, an error	is set and DM_FAILURE is returned.

     enable should be set to DM_TRUE for enabling a track, and DM_FALSE	for
     disabling a track.

     mvGetTrackEnable

     This function gets	the enable flag	for the	track passed in	track.
     DM_TRUE is	returned if the	track is enabled, and DM_FALSE if disabled.

NOTES    [Toc]    [Back]

     mvGetMovieDuration	does NOT take into account track enabled states.
