Detailed Description

Provides a interface to control a media player

The QIviMediaPlayer provides methods to control a media player. This media player can be local or even a remote device you are connected to e.g. over bluetooth.

By default the autoDiscovery is turned to Automatic for this feature and most likely will connect to a local media player instance.

Member Function Documentation

QIviMediaPlayer::QIviMediaPlayer(QObject *parent = nullptr)

Constructs a QIviMediaPlayer.

The parent argument is passed on to the QIviAbstractFeature base class.

[override virtual protected] void QIviMediaPlayer::clearServiceObject()

Reimplemented from QIviAbstractFeature::clearServiceObject().

[override virtual protected] void QIviMediaPlayer::connectToServiceObject(QIviServiceObject *serviceObject)

Reimplemented from QIviAbstractFeature::connectToServiceObject().

[slot] void QIviMediaPlayer::next()

Skips to the next track in the playQueue.

See also playMode.

[slot] void QIviMediaPlayer::pause()

Pauses the currently ongoing playback.

See also play() and stop().

[slot] void QIviMediaPlayer::play()

Starts to play the current track. If the playQueue is empty it's up to the backend to decide what to do.

See also pause() and stop().

[slot] void QIviMediaPlayer::previous()

Skips to the previous track in the playQueue.

See also playMode.

[slot] void QIviMediaPlayer::seek(qint64 offset)

Seeks into the current track using offset.

The offset can be positive or negative to either seek forward or backward. A successful seek will result in a change of the position property.

[slot] void QIviMediaPlayer::stop()

Stops the currently ongoing playback.
