20170339341 · 2017-11-23 ·

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 decoding device receives a 360 degree video stream as input and decodes the 360 degree video stream, and a memory device stores the 360 degree video stream and viewing history data associated with the 360 degree video stream. A rendering device may render the decoded stream using view angles from the viewing history data. In one or more implementations, an object tracking device tracks one or more objects in the decoded 360 degree video stream and provides one or more tracking angles associated with the objects. The rendering device may render the decoded 360 degree video stream using the one or more tracking angles to keep at least one object in the 360 degree video stream for one or more rendered frames.
