Namespace:  Microsoft.Web.Media.SmoothStreaming
Assembly:  Microsoft.Web.Media.SmoothStreaming (in Microsoft.Web.Media.SmoothStreaming.dll)

public void SetPlaybackRate(
	double playbackRate
)

Parameters

playbackRate
Type: System..::..Double
The playback rate.

For more information and for examples, see Fast Forward and Rewind Modes (IIS Smooth Streaming).

To set the playback rate, use the SetPlaybackRate method using a value from the SupportedPlaybackRates collection.

The following example shows how to get the available playback rates.

// Usable playback rates
    IList<double> playbackRates = SmoothPlayer.SupportedPlaybackRates;

After the previous line of code runs the list will contain the following values:

-8.0, -4.0, 0.5, 1, 4.0, 8.0.

Positive values set the playback rate to half the normal speed, 4.0 times the normal speed, or 8.0 times the normal speed. Negative values rewind the media stream at rates that are multiples of the normal speed by factors of -4.0 or -8.0.

The following example shows how to call the SetPlaybackRate method using a value from the SupportedPlaybackRates collection.

    SmoothPlayer.SetPlaybackRate(playbackRates[2]);
