Abstract

The invention discloses a method, equipment and a system for preventing frame loss in process of video editing. The method comprises the steps of generating a virtual file chain table by a client and synchronizing to storage equipment, wherein the chain table comprises a plurality of chain table nodes, and each chain table node comprises a number and a description field of a file fragment; reading the data of a first file fragment from the number of the first file fragment in a request and returning to the client after the storage equipment receives a read request; determining a next chain table node of the chain table node including the serial number of the first file fragment in the virtual file chain table in accordance with the number of the first file fragment; obtaining the description filed of a second file fragment in a next chain table node; and storing the data of the second file fragment into a memory from the storage medium in accordance with the field, thereby hitting the data in the memory by each request and preventing the frame loss in process of video editing.

Description

technical field [0001] Embodiments of the present invention relate to video processing technologies, and in particular to a method, device and system for preventing frame loss during video editing. Background technique [0002] In the existing video editing technology, there are relatively strict requirements on the read delay of the storage device. The read delay refers to the time for the storage device to return data to the client after the video editing client initiates a read request to the storage device. , if the read delay is too long, it will cause the video software to have a "frame drop" problem. This is because, in the prior art, the video editing software run by the client can generally be divided into three parts: reading data thread, data buffer, and video editing thread. Data is output and filled into the data buffer, and the video editing thread reads the cached data from the data buffer for video processing. Most of the existing storage devices use disk s...
