Rate Property

Returns or sets a Double value specifying the title’s playback rate.

Syntax

MediaPlayer.Rate

Remarks

This property acts as a multiplier value that allows you to play the title at a faster or slower rate. The value 1.0 indicates the authored speed and is the default value. Note that the audio track becomes difficult to understand at rates lower than 0.5 and higher than 1.5. A playback rate of 2 equates to twice the normal playback speed.

ASF and VOD: Optimal values for Rate are values x where –10 ≤ x ≤ -1 or 1 ≤ x ≤ 10. Values for Rate with an absolute magnitude greater than 10 are allowable, but not very meaningful. Audio plays only when the Rate value is 1. An .asf or .vod file must be stopped and the AllowScan property must be true before you can set the Rate property. Negative values for Rate indicate reversed playback directions. Rate applies only to files that meet the same conditions as stated in the CanScan section.

Quartz: Rate can be a value x where 0 < x < 9. Negative values for Rate are not allowed. Rate values less than one represent slow-motion. Rate values above 9 are allowable, but not very meaningful.
