摘要：
A video processing method includes receiving a bitstream, processing the bitstream to obtain at least one syntax element from the bitstream, and decoding the bitstream to generate a current decoded frame having a rotated 360-degree image/video content represented in a 360-degree Virtual Reality (360 VR) projection format. The at least one syntax element signaled via the bitstream indicates rotation information of content-oriented rotation that is involved in generating the rotated 360-degree image/video content, and includes a first syntax element. When the content-oriented rotation is enabled, the first syntax element indicates a rotation degree along a specific rotation axis.
