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.

Abstract: A method and an apparatus for processing video data. The method includes: parsing media presentation description to obtain flag information, where the flag information is used to identify a first representation of a video, where playing duration of a segment in the first representation is shorter than playing duration of a segment in a second representation of the video; obtaining switching instruction information, where the switching instruction information is used to instruct to switch from a current spatial object to a target spatial object; determining a target representation from the first representation of the video based on the flag information and the switching instruction information, where the target representation corresponds to the target spatial object; and obtaining a current playing moment of the video, and obtaining a target representation segment based on the current playing moment and the target representation.

Abstract: The present disclosure discloses a media information processing method and apparatus. The method includes: obtaining media data that includes indication information and at least one frame of picture data. The indication information is used to indicate whether a prediction pixel corresponding to a pixel in a picture exceeds a boundary in a preset direction. The method further includes decoding the frame(s) of picture data based on the indication information. According to the media information processing method and apparatus in the present disclosure, it is possible to splice a plurality of sub-bitstreams, and required bitstreams are spliced and then are decoded, so that a plurality of sub-picture sequences can be decoded by using only a single decoder.
