Abstract: Example video data processing methods and apparatus are disclosed. One example method includes receiving a first stream from a client, where the first bitstream is obtained by encoding image data in a specified spatial object. The specified spatial object is part of panoramic space, and a size of the specified spatial object is larger than a size of a spatial object of the panoramic space corresponding to viewport information. The spatial object corresponding to the viewport information is located in the specified spatial object. The client receives a second stream, where the second bitstream is obtained by encoding image data of a panoramic image of the panoramic space with a lower resolution than a resolution of the image data included in the specified spatial object. The client plays the second bitstream and first bitstream.

Abstract: Example video data processing methods and apparatus are disclosed. One example method includes obtaining viewport information by a server. The server obtains spatial object information based on the viewport information, where the spatial object information is used to describe a specified spatial object in panoramic space. The server obtains a first bitstream, where the first bitstream is obtained by encoding image data in the specified spatial object. The server obtains a second bitstream, where the second bitstream is obtained by encoding image data in the panoramic space. The server transmits the first bitstream and the second bitstream to a client.
