KnownCameraAudioVideoProperties.H264QuantizationParameter property

Applies to Windows Phone only

Specifies the quantization parameter (QP) used with H264 video encoding.

Syntax


public static Guid H264QuantizationParameter { get; }

Property value

Type: System.Guid [.NET] | Platform::Guid [C++]

The ID of the quantization parameter (QP).

Remarks

The QP determines how much spacial detail is preserved during encoding. A very low QP preserves most of the spacial detail, resulting in optimal quality. Although a higher QP introduces some lose of quality, it helps the encoder achieve a lower bit rate.

This property is for use with the AudioVideoCaptureDevice class. In the AudioVideoCaptureDevice class, the GetProperty class gets the current value of the property (of type System.UInt32). The SetProperty method sets the property to a new value. Not all values may be supported on each phone. Use the GetSupportedPropertyRange method to learn more about this property.
