Writing method of video files and recording equipment

Abstract

The invention provides a writing method of video files and recording equipment. According to the writing method and the recording equipment, the problem that the video files are slow in writing is solved. The invention relates to a file writing method, in particular to a writing method of the video files. The method comprises the following steps of acquiring the size of a cluster of a file system of a memory; if the size of the cluster is acquired, setting the size of the cluster as a reference size; distributing the capacity of a buffer pool into integral multiple of the reference size; receiving a writing request, and judging whether the rest writable capacity of the buffer pool is greater than the request capacity corresponding to a writing request or not; if the writable capacity is greater than the request capacity, writing data corresponding to the writing request into the buffer pool, and updating the writable capacity of the buffer pool; if the writable capacity is smaller than or equal to the request capacity, writing request data with the size about the writable capacity into the buffer pool, wherein the request data are data corresponding to the writing request; then writing the data of the buffer pool into the memory, and requesting to write request data which are not written into the buffer pool into the buffer pool. According to the writing method and the recording equipment provided by the invention, the service life of the memory can be prolonged.

Description

technical field [0001] The invention relates to a method for writing files, and is especially designed for writing video files. Background technique [0002] With the improvement of CPU main frequency and video encoder performance of current consumer electronic products, the products generally have a video recording function with a resolution of 1080P or higher, and even require multi-channel high-definition video recording. In order to ensure the life of the internal storage of the product, generally such products require customers to use external storage devices for storage, such as SD cards, hard drives, etc. In this case, it is often encountered that the writing performance of the external storage is not enough, which affects the effect of the video recording and indirectly reduces the life of the external storage. Contents of the invention [0003] A simplified overview of one or more aspects is presented below in an attempt to provide a basic understanding of such a...
