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.

Variable Documentation

const char ReEncode[] = "REENCODE_STREAM"

static

Specifies whether a stream will be reencoded.

This parameter is an integer.

The supported values are defined in the primo::avblocks::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 always done even if the input and the output formats are equivalent. The case when this parameter is Use::Off is not implemented.
