Abstract
In a system for 360 degree video capture and playback, 360 degree video may be captured, stitched, encoded, decoded, rendered, and played-back. In one or more implementations, a video capture device captures 360 degree video in a first projection format, and an encoding device encodes the captured 360 degree video into a 360 degree video bitstream. In some aspects, the 360 degree video bitstream is encoded with an indication of the first projection format. In one or more implementations, a rendering device converts the decoded 360 degree video bitstream from the first projection format to a second projection format based on the indication. In one or more implementations, a processing device generates projection maps where each is respectively associated with a different projection format, and a rendering device renders the decoded 360 degree video bitstream using one of the projections maps.
