Disabling Movies and Tracks

The Movie Toolbox services only movies and tracks that are active. This section describes functions that allow your application to enable and disable tracks and movies.

You can use the SetMovieActive function to activate and deactivate a movie. Use the GetMovieActive function to determine whether a movie is active.

Similarly, your application can use the SetTrackEnabled function to enable and disable a track. Use the GetTrackEnabled function to determine whether a track is enabled. The Movie Toolbox also allows you to assign alternate tracks based on language or quality criteria. Functions that work with alternate tracks are discussed in "Working With Alternate Tracks" beginning on page 2-191.
