The decoder behavior strictly conforms to the SPEC. All the decoder behaviors conform to the SPEC, not including any nonstandard behavior which is not mentioned in the SPEC. The decoder behavior normally conforms to the SPEC. Most behaviors conform to the SPEC but including some nonstandard features which are widely used or often used in the industry practice. This meets the request of real streams and usages, but may not 100% conform to the SPEC. It has very low risk. E.g., we will output pictures without waiting DPB being full for the lower latency, which may cause B frame disorder when there are reference frames with smaller POC after it in decoder order. And the baseline profile may be mapped to the constrained-baseline profile, but it may have problems when a real baseline stream comes with FMO or ASO. The decoder behavior flexibly conforms to the SPEC. It uses the nonstandard features more aggressively in order to get better performance(for example, lower latency). It may change the result of the decoder and should be used carefully. Besides including all risks in *normal* mode, it has more risks, such as frames disorder when reference frames POC decrease in decoder order.

This is used for Y AC coefficients and as the base value for the other quantizers indicates the Y DC quantizer relative to base_q_idx indicates the UV DC quantizer relative to base_q_idx indicates the UV AC quantizer relative to base_q_idx Reference modes: Specify the type of inter prediction to be used Indicates that all the inter blocks use only a single reference frame Requires all the inter blocks to use compound mode Allows each individual inter block to select between single and compound prediction modes See "6.2.11 Segmentation params syntax" and "7.2.10 Segmentation params syntax". When @segmentation_update_data is equal to zero, parser will fill @feature_enabled and by @feature_data using previously parsed values. equal to 1 indicates that this frame makes use of the segmentation tool equal to 1 indicates that the segmentation map should be updated during the decoding of this frame specify the probability values to be used when decoding segment_id 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 equal to 1 indicates that new parameters are about to be specified for each segment 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 indicates whether feature is enabled or not segmentation feature data This object is used to parse VP9 bitstream header.
