The metadata key to retrieve the information about the album title of the data source.

The metadata key to retrieve the information about the performers or artist associated with the data source.

The metadata key to retrieve the information about the artist of the data source.

The metadata key to retrieve the information about the author of the data source.

The metadata key to retrieve the year when the data source was created or modified.

This option is used with getFrameAtTime(long, int) to retrieve a frame (not necessarily a key frame) associated with a data source that is located closest to or at the given time.

This option is used with getFrameAtTime(long, int) to retrieve a sync (or key) frame associated with a data source that is located closest to (in time) or at the given time.

This option is used with getFrameAtTime(long, int) to retrieve a sync (or key) frame associated with a data source that is located right after or at the given time.

This option is used with getFrameAtTime(long, int) to retrieve a sync (or key) frame associated with a data source that is located right before or at the given time.

Call this method after setDataSource(). This method retrieves the meta data value associated with the keyCode. The keyCode currently supported is listed below as METADATA_XXX constants. With any other value, it returns a null pointer.

Call this method after setDataSource(). This method finds the optional graphic or album art associated associated with the data source. If there are more than one pictures, (any) one of them is returned.

Call this method after setDataSource(). This method finds a representative frame close to the given time position by considering the given option if possible, and returns it as a bitmap. This is useful for generating a thumbnail for an input data source or just obtain and display a frame at the given time position.

Call this method after setDataSource(). This method finds a representative frame close to the given time position if possible, and returns it as a bitmap. This is useful for generating a thumbnail for an input data source. Call this method if one does not care how the frame is found as long as it is close to the given time; otherwise, please call getFrameAtTime(long, int).

Call this method after setDataSource(). This method finds a representative frame at any time position if possible, and returns it as a bitmap. This is useful for generating a thumbnail for an input data source. Call this method if one does not care about where the frame is located; otherwise, please call getFrameAtTime(long) or getFrameAtTime(long, int)

Call it when one is done with the object. This method releases the memory allocated internally.

Sets the data source (FileDescriptor) to use. It is the caller's responsibility to close the file descriptor. It is safe to do so as soon as this call returns. Call this method before the rest of the methods in this class. This method may be time-consuming.

Sets the data source (file pathname) to use. Call this method before the rest of the methods in this class. This method may be time-consuming.

Sets the data source as a content Uri. Call this method before the rest of the methods in this class. This method may be time-consuming.

Called before the object's memory is reclaimed by the VM. This can only happen once the garbage collector has detected that the object is no longer reachable by any thread of the running application.

The method can be used to free system resources or perform other cleanup before the object is garbage collected. The default implementation of the method is empty, which is also expected by the VM, but subclasses can override finalize() as required. Uncaught exceptions which are thrown during the execution of this method cause it to terminate immediately but are otherwise ignored.

Note that the VM does guarantee that finalize() is called at most once for any object, but it doesn't guarantee when (if at all) finalize() will be called. For example, object B's finalize() can delay the execution of object A's finalize() method and therefore it can delay the reclamation of A's memory. To be safe, use a ReferenceQueue, because it provides more control over the way the VM deals with references during garbage collection.
