KnownCameraAudioVideoProperties.H264QuantizationParameter property
Specifies the quantization parameter (QP) used with H264 video encoding.
Syntax
public static Guid H264QuantizationParameter { get; }
Public Shared ReadOnly Property H264QuantizationParameter As Guid
public:
static property Guid H264QuantizationParameter {
Guid 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.
