Detailed Description

Defines parameters that can be passed to the transcoder and to the components that are used in the transcoding process.

A parameter can be used with one or more components like decoders, encoders, demuxers, muxers, and others.

A parameter can apply to:

• any component

• a certain component category like encoders, decoders, demuxers, muxers, etc.

• a component that handles a specific format like H.264 encoder, MPEG-2 encoder, MPEG-2 muxer, etc.

• a specific implementation of a component, or a block like PrimoCodecs H.264 encoder

The value representation, range and interpretation is different for each parameter.

Member Data Documentation

HardwareEncoder

string HardwareEncoder = "HARDWARE_ENCODER"

static

Specifies which hardware encoder shall be used.

This parameter is an integer.

The supported values are defined in HardwareEncoder enum. The default value is HardwareEncoder.Off.

HardwareEncoderApi

string HardwareEncoderApi = "HARDWARE_ENCODER_API"

static

Specifies which hardware API shall be used.

This parameter is an integer.

The supported values are defined in HwApi enum. The default value is HwApi.None which lets AVBlocks select the hardware API.

HardwareEncoderDevice

string HardwareEncoderDevice = "HARDWARE_ENCODER_DEVICE"

static

Specifies the device ID that shall be used for hardware encoding.

This parameter is an integer.

The device ID includes uniquely identified devices that support the hardware encoder specified by the HardwareEncoder parameter. The default value is 0.

ReEncode

string ReEncode = "REENCODE_STREAM"

static

Specifies whether a stream will be reencoded.

This parameter is an integer.

The supported values are defined in Use enum. The default value is Use.Auto.

If this parameter is Use::Auto the reencoding is done only when the input and the output formats are not equivalent. If this parameter is Use::On the reencoding is done always even if the input and the output formats are equivalent. The case when this parameter is Use::Off is not implemented.
