MovieImportSetSampleDuration

The MovieImportSetSampleDuration function allows an application to set the sample duration for new samples to be created with your component.

pascal ComponentResult MovieImportSetSampleDuration
                                  (ComponentInstance ci,
                                    TimeValue duration,
                                    TimeScale scale);

ci

Identifies the application's connection to your movie data import component.

duration

Specifies the sample duration in units specified by the scale parameter.

scale

Specifies the time scale for the duration value. This may be any arbitrary time scale; that is, it may not correspond to the movie's time scale. You should convert this time scale to the movie's time scale before using the duration value, using the Movie Toolbox's ConvertTimeScale function.

DESCRIPTION

Applications may use the MovieImportSetSampleDuration function to set the duration of samples to be added by your movie data import component. This duration is expressed in an arbitrary time scale.
