Description

This sample code has been updated for QuickTime 5.0 README - QTFlattenToHandle QTFlattenToHandle.c defines functions that illustrate how to use the handle data handler. A data handler is a component (of type DataHandlerType) that is responsible for reading and writing a media's data. In other words, a data handler provides data input and output services to the media's media handler. Originally, QuickTime included a file data handler. QuickTime version 2.0 introduced the handle data handler (component subtype HandleDataHandlerSubType), which allows you to play movie data stored in memory rather than in a file. This sample code shows how to work with the handle data handler. Here, we will open a movie file and then flatten the movie data into a handle. Then we will play the movie from the handle. The essential step is to create a data reference record describing the handle and then pass that record, instead of an FSSpec record, to FlattenMovieData. To do this, set the flattenFSSpecPtrIsDataRefRecordPtr flag when calling FlattenMovieData.
