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.

Enjoy,
