segmentation feature data
indicates whether feature is enabled or not
equal to 0 indicates that the segmentation parameters represent adjustments relative to the standard values. equal to 1 indicates that the segmentation parameters represent the actual values to be used
equal to 1 indicates that this frame makes use of the segmentation tool
specify the probability values to be used when decoding seg_id_predicted
equal to 1 indicates that the updates to the segmentation map are coded relative to the existing segmentation map
specify the probability values to be used when decoding segment_id
equal to 1 indicates that new parameters are about to be specified for each segment
equal to 1 indicates that the segmentation map should be updated during the decoding of this frame
See "6.2.11 Segmentation params syntax" and "7.2.10 Segmentation params syntax". When
segmentation_update_datais equal to zero, parser will fillfeature_enabledand byfeature_datausing previously parsed values.
