Detailed Description

The QMediaGaplessPlaybackControl class provides access to the gapless playback related control of a QMediaService. If a QMediaService supports gapless playback it will implement QMediaGaplessPlaybackControl. This control provides a means to set the next media or crossfade time for smooth transitions between tracks. The functionality provided by this control is exposed to application code through the QMediaPlayer class.

The interface name of QMediaGaplessPlaybackControl is "com.copperspice.CS.mediaGaplessPlaybackControl/1.0" as defined in QMediaGaplessPlaybackControl_iid.

Constructor & Destructor Documentation

QMediaGaplessPlaybackControl::~QMediaGaplessPlaybackControl ( )

virtual

Destroys a gapless playback control.

QMediaGaplessPlaybackControl::QMediaGaplessPlaybackControl ( QObject * parent = nullptr )

explicitprotected

Constructs a new gapless playback control with the given parent.

Method Documentation

void QMediaGaplessPlaybackControl::advancedToNextMedia ( )

signal

Signals when the player advances to the next media, the content of next media will be cleared.

See also: nextMedia()

qreal QMediaGaplessPlaybackControl::crossfadeTime ( ) const

pure virtual

Returns current crossfade time in seconds.

See also: setCrossfadeTime().

void QMediaGaplessPlaybackControl::crossfadeTimeChanged ( qreal crossfadeTime )

signal

Signals the crossfadeTime has changed.

See also: crossfadeTime()

bool QMediaGaplessPlaybackControl::isCrossfadeSupported ( ) const

pure virtual

Indicates whether crossfading is supported or not. If crossfading is not supported, setCrossfadeTime() will be ignored and the crossfadeTime() method will always return 0.

QMediaContent QMediaGaplessPlaybackControl::nextMedia ( ) const

pure virtual

Returns the content of the next media

See also: setNextMedia()

void QMediaGaplessPlaybackControl::nextMediaChanged ( const QMediaContent & media )

signal

Signals that the next media has changed, either explicitly via setNextMedia() or when the player clears the next media while advancing to it.

See also: nextMedia()

void QMediaGaplessPlaybackControl::setCrossfadeTime ( qreal crossfadeTime )

pure virtual

Sets the crossfadeTime in seconds for smooth transition.

Positive value means how much time it will take for the next media to transit from silent to full volume and vice versa for current one. So both current and the next one will be playing during this period of time.

A crossfade time of zero or negative will result in gapless playback, suitable for some continuous media.

See also: crossfadeTime()

void QMediaGaplessPlaybackControl::setNextMedia ( const QMediaContent & media )

pure virtual

Sets the next media for smooth transition.

See also: nextMedia()
