Placeholder documentation for H264Settings
public class H264Settings
The H264Settings type exposes the following members
Gets and sets the property AdaptiveQuantization. Adaptive quantization. Allows intra-frame quantizers to vary to improve visual quality.
Gets and sets the property AfdSignaling. Indicates that AFD values will be written into the output stream. If afdSignaling is "auto", the system will try to preserve the input AFD value (in cases where multiple AFD values are valid). If set to "fixed", the AFD value will be the value configured in the fixedAfd parameter.
Gets and sets the property Bitrate. Average bitrate in bits/second. Required for VBR, CBR, and ABR. For MS Smooth outputs, bitrates must be unique when rounded down to the nearest multiple of 1000.
Gets and sets the property BufFillPct. Percentage of the buffer that should initially be filled (HRD buffer model).
Gets and sets the property BufSize. Size of buffer (HRD buffer model) in bits/second.
Gets and sets the property ColorMetadata. Includes colorspace metadata in the output.
Gets and sets the property EntropyEncoding. Entropy encoding mode. Use cabac (must be in Main or High profile) or cavlc.
Gets and sets the property FixedAfd. Four bit AFD value to write on all frames of video in the output stream. Only valid when afdSignaling is set to 'Fixed'.
Gets and sets the property FlickerAq. If set to enabled, adjust quantization within each frame to reduce flicker or 'pop' on I-frames.
Gets and sets the property FramerateControl. This field indicates how the output video frame rate is specified. If "specified" is selected then the output video frame rate is determined by framerateNumerator and framerateDenominator, else if "initializeFromSource" is selected then the output video frame rate will be set equal to the input video frame rate of the first input.
Gets and sets the property FramerateDenominator. Framerate denominator.
Gets and sets the property FramerateNumerator. Framerate numerator - framerate is a fraction, e.g. 24000 / 1001 = 23.976 fps.
Gets and sets the property GopBReference. Documentation update needed
Gets and sets the property GopClosedCadence. Frequency of closed GOPs. In streaming applications, it is recommended that this be set to 1 so a decoder joining mid-stream will receive an IDR frame as quickly as possible. Setting this value to 0 will break output segmenting.
Gets and sets the property GopNumBFrames. Number of B-frames between reference frames.
Gets and sets the property GopSize. GOP size (keyframe interval) in units of either frames or seconds per gopSizeUnits. Must be greater than zero.
Gets and sets the property GopSizeUnits. Indicates if the gopSize is specified in frames or seconds. If seconds the system will convert the gopSize into a frame count at run time.
Gets and sets the property Level. H.264 Level.
Gets and sets the property LookAheadRateControl. Amount of lookahead. A value of low can decrease latency and memory usage, while high can produce better quality for certain content.
Gets and sets the property MaxBitrate. Maximum bitrate in bits/second (for VBR mode only).
Gets and sets the property MinIInterval. Only meaningful if sceneChangeDetect is set to enabled. Enforces separation between repeated (cadence) I-frames and I-frames inserted by Scene Change Detection. If a scene change I-frame is within I-interval frames of a cadence I-frame, the GOP is shrunk and/or stretched to the scene change I-frame. GOP stretch requires enabling lookahead as well as setting I-interval. The normal cadence resumes for the next GOP. Note: Maximum GOP stretch = GOP size + Min-I-interval - 1
Gets and sets the property NumRefFrames. Number of reference frames to use. The encoder may use more than requested if using B-frames and/or interlaced encoding.
Gets and sets the property ParControl. This field indicates how the output pixel aspect ratio is specified. If "specified" is selected then the output video pixel aspect ratio is determined by parNumerator and parDenominator, else if "initializeFromSource" is selected then the output pixsel aspect ratio will be set equal to the input video pixel aspect ratio of the first input.
Gets and sets the property ParDenominator. Pixel Aspect Ratio denominator.
Gets and sets the property ParNumerator. Pixel Aspect Ratio numerator.
Gets and sets the property Profile. H.264 Profile.
Gets and sets the property RateControlMode. Rate control mode.
Gets and sets the property ScanType. Sets the scan type of the output to progressive or top-field-first interlaced.
Gets and sets the property SceneChangeDetect. Scene change detection. Inserts I-frames on scene changes when enabled.
Gets and sets the property Slices. Number of slices per picture. Must be less than or equal to the number of macroblock rows for progressive pictures, and less than or equal to half the number of macroblock rows for interlaced pictures.This field is optional; when no value is specified the encoder will choose the number of slices based on encode resolution.
Gets and sets the property Softness. Softness. Selects quantizer matrix, larger values reduce high-frequency content in the encoded image.
Gets and sets the property SpatialAq. If set to enabled, adjust quantization within each frame based on spatial variation of content complexity.
Gets and sets the property Syntax. Produces a bitstream compliant with SMPTE RP-2027.
Gets and sets the property TemporalAq. If set to enabled, adjust quantization within each frame based on temporal variation of content complexity.
Gets and sets the property TimecodeInsertion. Determines how timecodes should be inserted into the video elementary stream.- 'disabled': Do not include timecodes- 'picTimingSei': Pass through picture timing SEI messages from the source specified in Timecode Config
