                    _members

Declaration

Swift

public static var _members: [AWSShapeMember]


                    
                    
                    bitrate

Specify the average bitrate in bits per second. Valid bitrates depend on the coding mode.

Declaration

Swift

public let bitrate: Int?


                    
                    
                    bitstreamMode

Specify the bitstream mode for the AC-3 stream that the encoder emits. For more information about the AC3 bitstream mode, see ATSC A/52-2012 (Annex E).

Declaration

Swift

public let bitstreamMode: Ac3BitstreamMode?


                    
                    
                    codingMode

Dolby Digital coding mode. Determines number of channels.

Declaration

Swift

public let codingMode: Ac3CodingMode?


                    
                    
                    dialnorm

Sets the dialnorm for the output. If blank and input audio is Dolby Digital, dialnorm will be passed through.

Declaration

Swift

public let dialnorm: Int?


                    
                    
                    dynamicRangeCompressionProfile

If set to FILM_STANDARD, adds dynamic range compression signaling to the output bitstream as defined in the Dolby Digital specification.

Declaration

Swift

public let dynamicRangeCompressionProfile: Ac3DynamicRangeCompressionProfile?


                    
                    
                    lfeFilter

Applies a 120Hz lowpass filter to the LFE channel prior to encoding. Only valid with 3_2_LFE coding mode.

Declaration

Swift

public let lfeFilter: Ac3LfeFilter?


                    
                    
                    metadataControl

When set to FOLLOW_INPUT, encoder metadata will be sourced from the DD, DD+, or DolbyE decoder that supplied this audio data. If audio was not supplied from one of these streams, then the static metadata settings will be used.

Declaration

Swift

public let metadataControl: Ac3MetadataControl?


                    
                    
                    sampleRate

This value is always 48000. It represents the sample rate in Hz.

Declaration

Swift

public let sampleRate: Int?


                    
                    
                    init(bitrate:bitstreamMode:codingMode:dialnorm:dynamicRangeCompressionProfile:lfeFilter:metadataControl:sampleRate:)

Undocumented

Declaration

Swift

public init(bitrate: Int? = nil, bitstreamMode: Ac3BitstreamMode? = nil, codingMode: Ac3CodingMode? = nil, dialnorm: Int? = nil, dynamicRangeCompressionProfile: Ac3DynamicRangeCompressionProfile? = nil, lfeFilter: Ac3LfeFilter? = nil, metadataControl: Ac3MetadataControl? = nil, sampleRate: Int? = nil)


                    
                    
                    validate(name:)

Declaration

Swift

public func validate(name: String) throws
