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
The present invention relates to special video effect processes and synthetic a kind of platform technology field, particularly the network-caching method based on cloud platform of making.
Background technology
In the prior art in video later stage special effect processing and synthetic making, normally one group of computer collaborative work in same group of networks.Special video effect is processed with synthetic making the cache file generating in video post process is left on local computer, improve the post-production efficiency of local computer, but the computer in consolidated network group intercepts each other on buffer memory, cannot for make the computer of same video lens or fragment in consolidated network group, provide corresponding buffer memory service each other.
Cloud platform allows developers or the program of finishing writing is placed on to " cloud " inner operation, or " cloud " the inner service providing of use, or the two all, turns to cloud computing, is the great change that industry will face.
In realizing process of the present invention, inventor finds to exist in prior art following shortcoming:
In prior art, worked in coordination with while processing with each synthetic computer starting project file to special video effect and all needed to generate buffer memory one time, and each intercomputer cannot share the cache file of generation, the editor's progress that cannot upgrade in time, has reduced the efficiency of collaborative work.
Summary of the invention
In order to solve above technical problem, the invention provides a kind of network-caching method based on cloud platform, the method comprises:
Initialization cloud platform terminal, on described cloud platform terminal, pre-configured sensing is for preserving the path of disk of the cloud Platform Server of cache file;
Cloud Platform Server described in initialization, the file header space of reserved described cache file on the disk of described cloud Platform Server; Fileversion number and the code encoding/decoding mode of self-defined described cache file in described file header space;
Described cloud platform terminal is kept at the description of each frame image data of this locality in local internal memory;
Described cloud platform terminal is write described each frame image data of this locality behind described file header space, and in described file header space recording of video frame number;
Described cloud platform terminal, when preserving engineering, writes the description of described each frame image data of preserving in the local internal memory of described cloud platform terminal in described file header space;
Between the described video frame number of described cloud platform terminal in described file header space and described code encoding/decoding mode, insert the invalid video frame number for protocol failure video section;
Described cloud platform terminal completes and writes described cache file to the disk of described cloud Platform Server.
When the data volume of the description of described view data is greater than reserved described file header space, calculate the space size that the description of described view data also needs, the view data of the space size that the description that and then occupies described view data in described cache file after the description of described view data is also needed moves to the end of described cache file, revises the description of described view data simultaneously.
When described invalid video section comprises continuous section, using the frame number of the first frame of described invalid video section and the frame number of last frame as described invalid video frame number.
According to the pre-configured sensing of described cloud platform terminal, for preserving the path of disk of the cloud Platform Server of cache file, find corresponding described cache file; Read described fileversion number; Judge that whether described fileversion number is identical with the version number of described cloud platform terminal, if so, read described video frame number; Judge that whether described video frame number is non-vanishing, if so, read and record the description of described code encoding/decoding mode and described view data; Judge whether to read the description of whole described view data; If so, read invalid video frame number; According to described invalid video frame number, deleting the view data that described invalid video frame number is corresponding describes; According to the view data except view data corresponding to described invalid video frame number described, describe and obtain view data.
The described description that judges whether to read whole described view data, is specially: Yi Zhengwei unit starts from scratch and reads until reach described video frame number.
Compared with prior art, the embodiment of the present invention has the following advantages: by cache file is kept on cloud Platform Server, make each terminal of collaborative work equal.When terminal, open project file used while making video last time, will automatically load the corresponding cache file of preserving on cloud Platform Server, needn't again take time and generate a buffer memory.So can save the operating time, raise the efficiency.Simultaneously, because cache file is placed on cloud Platform Server, and cache file itself has designed a kind of fixing file format, so terminal all can recognize corresponding cache file when opening project file on each computer of collaborative work, reading information, the cache file that a certain terminal like this generates in manufacturing process can be used for other people, and service, has improved collaborative work efficiency rate mutually.
