field
bitDepth: number

encoded bit depth

field
colorRange: number

specifies the black level and range of the luma and chroma signals

field
colorSpace: number

specifies the color space of the stream

field
deltaProbabilities: Vp9DeltaProbabilities

Modification to the probabilities encoded in the bitstream.

field
errorResilientMode: number

equal to 1 indicates that error resilient mode is enabled

field
frameContextIdx: number

field
frameHeaderLengthInBytes: number

length of uncompressed header

field
frameParallelDecodingMode: number

equal to 1 indicates that parallel decoding mode is enabled

field
frameToShowMapIdx: number

specifies the frame to be displayed. It is only available if show_existing_frame is 1

field
frameType: number

equal to 0 indicates that the current frame is a key frame

field
headerSizeInBytes: number
height: number

coded frame height

field
interpolationFilter: number

specifies the filter selection used for performing inter prediction

field
intraOnly: number

equal to 1 indicates that the frame is an intra-only frame

field
loopFilterParams: Vp9LoopFilterParams

a #GstVp9LoopFilterParams

field
losslessFlag: number

lossless mode decode

field
profile: number

encoded profile

field
quantizationParams: Vp9QuantizationParams

a #GstVp9QuantizationParams

field
refFrameIdx: Uint8Array

specifies which reference frames are used by inter frames

field
refFrameSignBias: Uint8Array

field
referenceMode: Vp9ReferenceMode

Is a derived syntax element that specifies the type of inter prediction to be used.

field
refreshFrameContext: number

equal to 1 indicates that the probabilities computed for this frame

field
refreshFrameFlags: number

contains a bitmask that specifies which reference frame slots will be updated with the current frame after it is decoded

field
renderAndFrameSizeDifferent: number

equal to 0 means that the render width and height are inferred from the frame width and height

field
renderHeight: number

render width of the frame

field
renderWidth: number

render width of the frame

field
resetFrameContext: number

specifies whether the frame context should be reset to default values

field
segmentationParams: Vp9SegmentationParams

a #GstVp9SegmentationParams

field
showExistingFrame: number

equal to 1, indicates the frame indexed by frame_to_show_map_idx is to be displayed

field
showFrame: number

indicate whether it is a displayable frame or not

field
subsamplingX: number

specify the chroma subsampling format for x coordinate

field
subsamplingY: number

field
width: number

coded frame width

field
name: string
