Abstract: A terminal for de-blocking filtering terminal is configured to determine that a first filtering boundary of a first to-be-filtered block in a target image belongs to a boundary of a pixel area in the target image, where the target image is a planar image obtained by splicing M pixel areas, the M pixel areas are M faces of a polyhedron with the M faces surrounding a spherical panorama image, and filter the first filtering boundary based on a pixel in the first to-be-filtered block and a pixel in a filtering reference block in the target image, where a boundary of the filtering reference block and the first filtering boundary coincide on an edge of the polyhedron with the M faces.

Abstract: A decoding method applied to the field of video processing, where the decoding method includes receiving an encoded bitstream of a two-dimensional panorama picture, determining an applicable spatial layout format of the two-dimensional panorama picture, parsing the encoded bitstream of the two-dimensional panorama picture to determine whether a spatial position relationship between sub-pictures in the two-dimensional panorama picture in the applicable spatial layout format is a default spatial position relationship, and decoding the encoded bitstream of the two-dimensional panorama picture based on the applicable spatial layout format and the default spatial position relationship when the spatial position relationship between the sub-pictures in the two-dimensional panorama picture in the applicable spatial layout format is the default spatial position relationship.
