摘要： A method and an apparatus for processing non-sequential point cloud media, a device and a storage medium. Said method comprises: processing non-sequential point cloud data of a static object by means of a GPCC encoding mode, to obtain a GPCC bit stream (S302); encapsulating the GPCC bit stream to generate entries of at least one GPCC region (S303); encapsulating the entries of the at least one GPCC region to generate at least one non-sequential point cloud media of the static object (S304); sending MPD signaling of the at least one non-sequential point cloud media (S305); receiving a first request message sent by a video playback device; and sending a first non-sequential point cloud media. The entries of the GPCC region are used for representing GPCC components of a three-dimensional (3D) space region corresponding to the GPCC region, and the non-sequential point cloud media comprises an identifier of the static object. The present invention allows for a user to purposefully request non-sequential point cloud media of the same static object many times, improving the user experience.
