QuickTime for Java: A Developer's Notebook

Exporting Movies

One of the most obviously useful components is the MovieExporter, which you can use to convert a QuickTime movie into a non-QuickTime format, such as AVI or MPEG-4.

How do I do that?

The quicktime.std.qtcomponents.MovieExporter class provides a convenient Java wrapper around movie exporter components. It requires that you pass it a subtype indicating which exporter you want—i.e., which format you want to export to. Example 4-2 shows how a MovieExporter can be created and used from a canned list of subtypes.

Note

Compile and run this example with ant run-ch04-simplemovieexport.
