Abstract:
An example device for decoding video data, the device including a memory configured to store video data; and one or more processors implemented in circuitry and configured to: determine that adaptive loop filter (ALF) information can be present in a picture header of a picture of the video data and cannot be present in a slice header; in response to determining that the ALF information can be present in the picture header and cannot be present in the slice header, determine that a picture header syntax structure is not present in the slice header (e.g., without decoding data representing a value for a syntax element indicating whether the picture header syntax structure is present in the slice header); and decode the picture according to the determination that the picture header syntax structure is not present in the slice header.
