1. A method, comprising:
padding a first depth image representative of a first set of depth values of first points of a point cloud frame, wherein the first points are nearer points of a point cloud from a projection plane;
padding a second depth image representative of a second set of depth values of second points of the point cloud frame, wherein the second points are farther points of the point cloud from the projection plane, and wherein one of the padded first depth image or the padded second depth image is predicted by using the other of the padded first depth image or the padded second depth image as a reference image; and
encoding a video stream comprising interleaving of the first set of depth values of the padded first depth image and the second set of depth values of the padded second depth image of the point cloud frame.
