Remarks

Get an instance of this class by calling MediaPlaybackSession.GetOutputDegradationPolicyState.

In some circumstances the system may degrade the playback of a media item, such as reducing the resolution (constriction), based on a policy rather than a performance issue. The object retrieved with this property allows you to determine if and why this policy-based degredation is occurring for telemetry purposes.

Properties

VideoConstrictionReason

Gets a value from the MediaPlaybackSessionVideoConstrictionReason enumeration specifying the reason why video is being constricted, if known.
