Method and apparatus with video encoding function with syntax element signaling of rotation information and method and apparatus with associated video decoding function

摘要

A video processing method receives a current input frame having a 360 degree image / video content represented in a 360 degree virtual reality (360VR) projection format; and the 360 degree image / video content in the current input frame. Applying content-oriented rotation to generate a content rotation frame having rotated 360 degree image / video content represented in a 360VR projection format; and encoding the content rotation frame to generate a bitstream; Signaling at least one syntax element via the bitstream, wherein the at least one syntax element is set to indicate rotation information of the content-oriented rotation.
