public class MediaController
extends QObject

The MediaController class controls optional features of a media file/device. Some media sources have content that the MediaObject does not provide control over, for instance, chapters in a DVD file. The functionality the media controller offers is dependent on the type of media source that is played back. Commonly, the media controller allows you to:

• Navigate between chapters.
• Navigate between titles.
• Select between angles.

The Feature enum explains these terms in more detail, and their context in playback of CD and DVD.

The media controller keeps a MediaObject, of which media source is played back. You can still call the media object's functions, e.g., stop(); this is all handled correctly by the media controller. You have the option of letting the media controller play all titles of a source in sequence by setting the autoplay titles option.

To start a playback using a media object, you call play() on the media object. To play a specific title, use setCurrentTitle() and then call play().

Warning: The Phonon::MediaController class is not yet supported by Qt backends.

Method Detail

autoplayTitles

public final boolean autoplayTitles()

Returns true if titles will automatically be played when the media is played; otherwise returns false.

The media controller will play the titles of the media source in sequence when the media object's play() function is called. If the autoplay option is disabled, the media object will play the MediaController::currentTitle(){current title} and then finish the playback.
