Abstract: This application provides a media data transmission method and an apparatus. The method includes: A client sends first information to a server. The client receives video data packets that correspond to a second target video picture and that are sent by the server. The first information is used to indicate spatial information of a region in which a first target video picture is located, and the first target video picture includes a video picture within a current viewport. The second target video picture includes the first target video picture, at least one of the video data packets corresponding to the second target video picture carries at least one piece of second information, and the second information is used to indicate spatial information of a region in which the second target video picture is located.

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.

Abstract: This application discloses a picture display order determining method which includes: obtaining a decoding order index value of a current picture and a decoding order index value of a previous picture that is adjacent to the current picture according to a decoding order; adding 1 to a cycle identifier value when the decoding order index value of the current picture is less than the decoding order index value of the previous picture; and determining a display order index value of the current picture based on a sum of the decoding order index value of the current picture and a preset positive integer multiple of the cycle identifier value. In this application, the display order index value of the current picture progressively increases based on a display order index value of a picture that is located before the current picture according to the decoding order.

Abstract: This application provides a media data processing method and apparatus. The method includes obtaining metadata information, where the metadata information is property information that describes media data, and the metadata information includes viewpoint identification information. The method further includes processing the media data based on the viewpoint identification information. In this application, media data corresponding to different viewpoints can be freely processed based on the viewpoint identification information.
