Abstract: In one embodiment, a method receives spherical content for video and generates face images from the spherical content to represent an image in the video. A two dimensional sheet for the face images is generated. A size of the face images is reduced and a pixel frame around each of the plurality of face images is added on the sheet. Also, a plurality of gaps are added on the sheet in between edges of the face images that are neighboring. The method then adds gap content in the plurality of gaps where the gap content is based on content in an area proximate to the plurality of gaps. The method encodes the face images, the pixel frame, and gap content on the sheet and sends the encoded sheet to a decoder. The face images are decoded for placement on an object structure to display the spherical content.
