MediaElement.SpeedRatio Property

Definition

Gets or sets the speed ratio of the media.

public double SpeedRatio { get; set; }

Property Value

The speed ratio of the media. The valid range is between 0 (zero) and infinity. Values less than 1 yield slower than normal playback, and values greater than 1 yield faster than normal playback. Negative values are treated as 0. The default value is 1.

Exceptions

The Clock property is not null.

Remarks

This property can be set only when the Clock property is null. When the Clock property is non-null, the timing engine controls media playback behavior.

Audio playback may not occur unless the value of SpeedRatio is 1.
