Syntax

public class MFHEVCEncoderSettings : IHEVCEncoderSettings, IVideoEncoder, IMediaBlockSettings, IEncoderTextInfo

Constructors

MFHEVCEncoderSettings()

Initializes a new instance of the MFHEVCEncoderSettings class.

Declaration

public MFHEVCEncoderSettings()

MFHEVCEncoderSettings(int)

Initializes a new instance of the MFHEVCEncoderSettings class.

Declaration

public MFHEVCEncoderSettings(int id)

Parameters

Type	Name	Description
int	id	The device identifier. Use GetDeviceIDs call to list IDs. 0 to use default device.

Fields

Name

The name.

Declaration

public static string Name

Field Value

Type	Description
string

Properties

BFrames

Gets or sets the maximum number of consecutive B frames.

Declaration

public uint BFrames { get; set; }

Property Value

Type	Description
uint	The b frames.

Bitrate

Gets or sets the bitrate in (Kbit/s).

Declaration

public uint Bitrate { get; set; }

Property Value

Type	Description
uint	The bitrate.

DeviceID

Gets the device identifier. Use GetDeviceIDs call to list IDs.

Declaration

public int DeviceID { get; }

Property Value

Type	Description
int	The device identifier.

GOPSize

Gets or sets the size of the GOP. It's the number of pictures from one GOP header to the next. Depending on GPU vendor implementation, zero gop-size might produce only one keyframe at the beginning (-1 for automatic).

Declaration

public int GOPSize { get; set; }

Property Value

Type	Description
int	The size of the GOP.

LowLatency

Gets or sets a value indicating whether low latency is enabled.

Declaration

public bool LowLatency { get; set; }

Property Value

Type	Description
bool	true if low latency is enabled; otherwise, false.

MaxBitrate

Gets or sets the maximum bitrate applied when rc-mode is "PCVBR" (Kbit/sec).

Declaration

public uint MaxBitrate { get; set; }

Property Value

Type	Description
uint	The maximum bitrate.

NumOfReferenceFrames

Gets or sets the number of reference frames.

Declaration

public uint NumOfReferenceFrames { get; set; }

Property Value

Type	Description
uint	The number of reference frames.

ParseStream

Gets or sets a value indicating whether to parse the video stream. True by default. Disable it for SRT streaming.

Declaration

public bool ParseStream { get; set; }

Property Value

Type	Description
bool	true if parse stream; otherwise, false.

Profile

Gets or sets the profile.

Declaration

public MFHEVCEncoderProfile Profile { get; set; }

Property Value

Type	Description
MFHEVCEncoderProfile	The profile.

QP

Gets or sets the QP applied when rc-mode is "QVBR".

Declaration

public uint QP { get; set; }

Property Value

Type	Description
uint	The QP.

QPB

Gets or sets the QP applied to B frames.

Declaration

public uint QPB { get; set; }

Property Value

Type	Description
uint	The QPB.

QPI

Gets or sets the QP applied to I frames.

Declaration

public uint QPI { get; set; }

Property Value

Type	Description
uint	The QPI.

QPP

Gets or sets the QP applied to P frames.

Declaration

public uint QPP { get; set; }

Property Value

Type	Description
uint	The QPP.

QualityVSSpeed

Gets or sets the quality vs speed tradeoff. [0, 33]: low complexity. [34, 66]: medium complexity. [67, 100]: high complexity.

Declaration

public uint QualityVSSpeed { get; set; }

Property Value

Type	Description
uint	The quality vs speed tradeoff.

RateControl

Gets or sets the rate control.

Declaration

public MFHEVCEncoderRCMode RateControl { get; set; }

Property Value

Type	Description
MFHEVCEncoderRCMode	The rate control.

VBVBufferSize

Gets or sets the size of the VBV buffer. 0 = MFT default.

Declaration

public uint VBVBufferSize { get; set; }

Property Value

Type	Description
uint	The size of the VBV buffer.
