autoRepresentations?: AutoRepresentation

Memberof

PerTitleConfiguration

codecBufsizeFactor?: number

This factor is used to calculate the bufsize of the codec configuration for the generated representations as a multiple of the targetBitrate

Memberof

H264PerTitleConfiguration

codecMaxBitrateFactor?: number

This factor is used to calculate the maxBitrate of the codec configuration for the generated representations as a multiple of the targetBitrate

Memberof

H264PerTitleConfiguration

codecMinBitrateFactor?: number

This factor is used to calculate the minBitrate of the codec configuration for the generated representations as a multiple of the targetBitrate

Memberof

H264PerTitleConfiguration

complexityFactor?: number

Will modify the assumed complexity for the Per-Title algorithm (> 0.0). Values higher than 1 will increase complexity and thus select smaller resolutions for given bitrates. This will also result in a higher bitrate for the top rendition. Values lower than 1 will decrease assumed complexity and thus select higher resolutions for given bitrates and also decrease the bitrate of the top rendition

Memberof

PerTitleConfiguration

fixedResolutionAndBitrateConfiguration?: PerTitleFixedResolutionAndBitrateConfiguration

Additional configuration for fixed resolution and bitrate templates

Memberof

PerTitleConfiguration

maxBitrate?: number

The maximum bitrate that will be used by the Per-Title algorithm. It will not generate any rendition with a higher bitrate.

Memberof

PerTitleConfiguration

maxBitrateStepSize?: number

The maximum ratio between the bitrates of neighbouring renditions, e.g., if the first bitrate is 240,000, a maximum ratio of 1.5 will require the next higher bitrate to be at most 360,000

Memberof

PerTitleConfiguration

minBitrate?: number

The minimum bitrate that will be used by the Per-Title algorithm.

Memberof

PerTitleConfiguration

minBitrateStepSize?: number

The minimum ratio between the bitrates of generated renditions, e.g. if the first bitrate is 240,000, a minimum ratio of 1.5 will require the next higher bitrate to be at least 360,000

Memberof

PerTitleConfiguration

resolutionScaleFactor?: number

This factor influences the resolution selection of the per-title algorithm. The default value is 0.0. negative values will lead to results where the algorithm will choose lower resolutions for given bitrates. A positive value will result in higher resolutions to be selected. The range of the factor is -5.0 to +5.0. Please note that changing this factor might also lead to slightly different bitrate selection by the algorithm.

PerTitleConfiguration

targetQualityCrf?: number

Desired target quality of the highest representation expressed as CRF value
