Method for processing projection-based frame that includes projection faces packed in cube-based projection layout with padding

摘要

A video processing method includes: obtaining a plurality of square projection faces from an omnidirectional content of a sphere according to a cube-based projection, scaling the square projection faces to generate a plurality of scaled projection faces, respectively, creating at least one padding region, generating a projection-based frame by packing the scaled projection faces and said at least one padding region in a projection layout of the cube-based projection, and encoding the projection-based frame to generate a part of a bitstream.
