Constructors

H264Layer()	Initializes a new instance of the H264Layer class.
H264Layer(Int32, String, String, String, Nullable<Int32>, Nullable<Int32>, String, Nullable<Int32>, Nullable<Boolean>, Nullable<H264VideoProfile>, String, Nullable<TimeSpan>, Nullable<Double>, Nullable<Int32>, Nullable<EntropyMode>)	Initializes a new instance of the H264Layer class.

Properties

AdaptiveBFrame	Gets or sets whether or not adaptive B-frames are to be used when encoding this layer. If not specified, the encoder will turn it on whenever the video profile permits its use. (Inherited from VideoLayer)
BFrames	Gets or sets the number of B-frames to be used when encoding this layer. If not specified, the encoder chooses an appropriate number based on the video profile and level. (Inherited from VideoLayer)
Bitrate	Gets or sets the average bitrate in bits per second at which to encode the input video when generating this layer. This is a required field. (Inherited from VideoLayer)
BufferWindow	Gets or sets the VBV buffer window length. The value should be in ISO 8601 format. The value should be in the range [0.1-100] seconds. The default is 5 seconds (for example, PT5S).
Crf	Gets or sets the value of CRF to be used when encoding this layer. This setting takes effect when RateControlMode of video codec is set at CRF mode. The range of CRF value is between 0 and 51, where lower values would result in better quality, at the expense of higher file sizes. Higher values mean more compression, but at some point quality degradation will be noticed. Default value is 23.
EntropyMode	Gets or sets the entropy mode to be used for this layer. If not specified, the encoder chooses the mode that is appropriate for the profile and level. Possible values include: 'Cabac', 'Cavlc'
FrameRate	Gets or sets the frame rate (in frames per second) at which to encode this layer. The value can be in the form of M/N where M and N are integers (For example, 30000/1001), or in the form of a number (For example, 30, or 29.97). The encoder enforces constraints on allowed frame rates based on the profile and level. If it is not specified, the encoder will use the same frame rate as the input video. (Inherited from VideoLayer)
Height	Gets or sets the height of the output video for this layer. The value can be absolute (in pixels) or relative (in percentage). For example 50% means the output video has half as many pixels in height as the input. (Inherited from Layer)
Label	Gets or sets the alphanumeric label for this layer, which can be used in multiplexing different video and audio layers, or in naming the output file. (Inherited from Layer)
Level	Gets or sets we currently support Level up to 6.2. The value can be Auto, or a number that matches the H.264 profile. If not specified, the default is Auto, which lets the encoder choose the Level that is appropriate for this layer.
MaxBitrate	Gets or sets the maximum bitrate (in bits per second), at which the VBV buffer should be assumed to refill. If not specified, defaults to the same value as bitrate. (Inherited from VideoLayer)
Profile	Gets or sets we currently support Baseline, Main, High, High422, High444. Default is Auto. Possible values include: 'Auto', 'Baseline', 'Main', 'High', 'High422', 'High444'
ReferenceFrames	Gets or sets the number of reference frames to be used when encoding this layer. If not specified, the encoder determines an appropriate number based on the encoder complexity setting.
Slices	Gets or sets the number of slices to be used when encoding this layer. If not specified, default is zero, which means that encoder will use a single slice for each frame. (Inherited from VideoLayer)
Width	Gets or sets the width of the output video for this layer. The value can be absolute (in pixels) or relative (in percentage). For example 50% means the output video has half as many pixels in width as the input. (Inherited from Layer)
