Parameters

crossfadeTime – qreal

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).
