• Introduction of the JQTCanvas class, a new lightweight version of the QTCanvas class which supports scaling of Flash content.

• A number of new QuickTime VR classes that encapsulate the various VR atom types.

• New classes in the quicktime.std.movies package. These include Idle manager bindings

  • NextTaskNeededSooner

  • IdleDispatcher

• Added support for MovieMedia Handler.

• Fixed DataProcs in the Sequence Grabber.

Support for JDK 1.4

QuickTime for Java now includes support for JDK 1.4 (Windows only). These are internal changes that should be transparent to your application.

New JQTCanvas

JQTCanvas, a new class that has been added to the quicktime.app.display package, is a lightweight version of the QTCanvas class. It is intended to behave in exactly the same way as QTCanvas, but with the following enhancement: the JQTCanvas class supports scaling of Flash content that is added to it via a moviePlayer. You may use the setFlashScaling(boolean) method to turn this feature on and off. If you use this new feature, you may need to allocate extra memory, since an offscreen buffer must be created that is the size of the onscreen image.

New QTVR Authoring Classes

A number of new QuickTime VR classes have been added in this release of QuickTime for Java. These classes encapsulate the various VR atom types, and are designed to help developers who are doing QuickTime VR work. They include

• QTVRAtom

• QTVRAngleRange

• QTVRCubicFace

• QTVRCubicView

• QTVRHotSpotInfo

• QTVRLinkHotSpot

• QTVRWorldHeader

• QTVRNodeHeader

• QTVRNodeLocation

• QTVRObjectSample

• QTVRPanoImaging

• QTVRPanoSample

• QTVRString

• QTVRTrackRefEntry

For more information on these new VR classes, refer to the JavaDocs accompanying this release.

Improved QuickTime Client Streaming Support

A number of new classes have been added that extend QuickTime for Java client streaming functionality to include support for stored movies. This support is provided via the Sourcer object. These new classes include

• Sourcer

• SourcerCallbackParams

• SourcerInitParams

• SourcerLoopParams

• SourcerTrackParams

• SourcerTimingParams

Note that the QuickTime for Java Client Streaming API is currently not available on the Windows platform.

For more information on these new classes, refer to the JavaDocs accompanying this release.

New Sprite Handler APIs

The following new sprite handler APIs have been added to this release of QuickTime for Java:

• Flashmediahandler.java

  private static native int FlashMediaGetSupportedSwfVersion (

  int mh,

  byte[] path);

• Movie.java

  private static native short NewMovieForDataRefFromHandle (

  int[] theMovie,

  int publicMovieHandle,

  short newMovieFlags,

  byte[] dataRefWasChanged,

  int dataRef,

  int dataRefType);

  private static native int FlattenMovieDataToDataRef (

  int theMovie,

  int movieFlattenFlags,

  int dataRef,

  int dataRefType,

  int creator,

  short scriptTag,

  int createMovieFileFlags);

• SpriteMediaHandler.java

  private static native int SpriteMediaDisposeImage(int mh,

  int imageIndex);

  private static native int SpriteMediaNewImage (int mh,

  byte[] imageURL);
