Embodiment

[0024] An embodiment of the present invention provides a network caching method based on a cloud platform. Such as figure 1 As shown, it is a flow chart of writing a cache file of a cloud platform-based network caching method according to the present invention, and the method includes:

[0025] Step S101, initializing the cloud platform terminal, pre-configuring on the cloud platform terminal a path pointing to the disk of the cloud platform server for saving the cache file;

[0026] Step S102, initialize the cloud platform server, reserve the file header space of the cache file on the disk of the cloud platform server; customize the file version number and codec of the cache file in the file header space Way;

[0027] Step S103, the cloud platform terminal saves the description of each frame of local image data in the local memory;

[0028] Step S104, after the described cloud platform terminal writes the local described each frame of image data into the file header space...

Abstract

The invention discloses a network caching method based on a cloud platform. The network caching method comprises: initializing a cloud platform and preconfiguring a path directing to a disk of the cloud platform on a cloud platform terminal; reserving file header space of a cache file on the disk of a cloud platform server and customizing a file version number and encoding and decoding modes in the file header space; using the cloud platform terminal to save description of local image data in a local memory; recording video frame number in the file header space after the local image data is written in the file header space; using the cloud platform terminal to write the description of every frame of image data saved in the memory of the cloud platform terminal in the file header space when the cloud platform terminal saves a project; and using the cloud platform terminal to insert an invalid video frame number used for recording an invalid video section between the video frame numbers and the encoding and decoding modes in the file header space. The method disclosed in the invention achieves that a terminal directly loads the cache file saved last time, and that every terminals share the cache file in order to improve cooperative work efficiency.

Description

technical field [0001] The invention relates to the technical field of video special effect processing and synthesis production platform, in particular to a cloud platform-based network caching method. Background technique [0002] In the prior art, in post-production special effect processing and synthesis of video, usually a group of computers work together in the same network group. Video special effects processing and synthesis production store the cache files generated during the video post-production process on the local computer to improve the post-production efficiency of the local computer, but the computers in the same network group are isolated from each other on the cache and cannot communicate with each other The computers that make the same video shot or segment in the same network group provide corresponding cache services. [0003] The cloud platform allows developers to either run the written programs in the "cloud", or use the services provided in the "clo...
