Abstract

A method for processing spherical video data is described including a data processor providing spherical video data in the form of projected video frames to an input of an encoder process, a projected video frame including one or more pixel regions, the one or more pixel regions representing pixels of spherical video data projected onto one or more 2D projection surfaces of a projection model, preferably an equirectangular or a 3D polyhedron projection model, for projecting spherical video data onto a rectangular 2D surface of a video frame; wherein the providing of spherical video data may comprise: generating a set of modified projected video frames on the basis of a projected video frame, the generating including applying different shift and/or rotation operations to pixels, preferably one or more pixel regions, of the selected projected video frame; applying an image analysis algorithm to the modified projected video frames, the image analysis algorithm determining an image analysis parameter for a least part of the modified projected video frames, the image analysis parameter being indicative for the encoding efficiency and/or image quality; and, selecting a modified projected video frame from the set of modified projected video frames, the selected modified projected video frame being associated with an image analysis parameter indicative of the best encoding efficiency and/or image quality.
