Cache management method and device

Abstract

The embodiment of the invention provides a cache management method and device, and relates to the technical field of video processing. Comprising the steps that description information of a first cache and description information of cache slices of the first cache are received, the first cache is used for caching a first media file, and the first media file is a media file comprising index information and position coordinates of face mark points of a target digital person; and creating a first buffer according to the first buffer and the description information of the buffer slice, so that a media access function writes decoding data of the first media file into the first buffer, and reading index information and position coordinates of the face mark point according to the description information of the face mark point of the target digital human. Some embodiments of the invention are used for solving the problem that an immersive media scene description framework cannot be used for realizing digital human animation and related processing based on the face mark points because the scene description file does not have related information for declaring the face mark points.
