MediaTrackEdited

The MediaTrackEdited function allows the Movie Toolbox to inform your derived media handler about edits to its track.

pascal ComponentResult MediaTrackEdited (ComponentInstance ci);

ci

Identifies the Movie Toolbox's connection to your derived media handler.

DESCRIPTION

The Movie Toolbox calls your derived media handler's MediaTrackEdited function whenever the track that is using your media is edited. While these edits do not directly affect the data in your media, they can change the way in which the movie uses your media's data.

Your derived media handler should support this function if you are caching location information about track edits, or if you are using any time values in the movie's time base. Whenever the Movie Toolbox calls this function, your media handler should recalculate this type of information.
