Syntax

public class MFH264EncoderSettings : IH264EncoderSettings, IVideoEncoder

Constructors

MFH264EncoderSettings(Int32)

Initializes a new instance of the MFH264EncoderSettings class.

Declaration

public MFH264EncoderSettings(int id = 0)

Parameters

Type	Name	Description
Int32	id	The device identifier. Use GetDeviceIDs call to list IDs. 0 to use default device.

Properties

BFrames

Gets or sets the maximum number of consecutive B frames.

Declaration

public uint BFrames { get; set; }

Property Value

Type	Description
UInt32	The b frames.

Bitrate

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

Declaration

public uint Bitrate { get; set; }

Property Value

Type	Description
UInt32	The bitrate.

CABAC

Gets or sets a value indicating whether CABAC entropy coding is enabled.

Declaration

public bool CABAC { get; set; }

Property Value

Type	Description
Boolean	true if CABAC is enabled; otherwise, false.

DeviceID

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

Declaration

public int DeviceID { get; }

Property Value

Type	Description
Int32	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
Int32	The size of the GOP.

Level

Gets or sets the level.

Declaration

public MFH264EncoderLevel Level { get; set; }

Property Value

Type	Description
MFH264EncoderLevel	The level.

LowLatency

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

Declaration

public bool LowLatency { get; set; }

Property Value

Type	Description
Boolean	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
UInt32	The maximum bitrate.

NumOfReferenceFrames

Gets or sets the number of reference frames.

Declaration

public uint NumOfReferenceFrames { get; set; }

Property Value

Type	Description
UInt32	The number of reference frames.

Profile

Gets or sets the profile.

Declaration

public MFH264EncoderProfile Profile { get; set; }

Property Value

Type	Description
MFH264EncoderProfile	The profile.

QP

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

Declaration

public uint QP { get; set; }

Property Value

Type	Description
UInt32	The QP.

QPB

Gets or sets the QP applied to B frames.

Declaration

public uint QPB { get; set; }

Property Value

Type	Description
UInt32	The QPB.

QPI

Gets or sets the QP applied to I frames.

Declaration

public uint QPI { get; set; }

Property Value

Type	Description
UInt32	The QPI.

QPP

Gets or sets the QP applied to P frames.

Declaration

public uint QPP { get; set; }

Property Value

Type	Description
UInt32	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
UInt32	The quality vs speed tradeoff.

RateControl

Gets or sets the rate control mode.

Declaration

public MFH264EncoderRCMode RateControl { get; set; }

Property Value

Type	Description
MFH264EncoderRCMode	The RC mode.

VBVBufferSize

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

Declaration

public uint VBVBufferSize { get; set; }

Property Value

Type	Description
UInt32	The size of the VBV buffer.
