Video stream cache distribution method and device

Abstract

The invention belongs to the field of video processing and particularly relates to a video stream cache distribution method and device. The invention aims to solve problems of the waste of a memory space, easy data loss and increased system overhead caused by a fixed length of a cache queue in the prior art. The video stream cache distribution method provided by the invention comprises a step of distributing a memory block containing video data as a cache block and storing the memory block into the cache block, a step of storing the cache block into a data center and storing an address of thecache block into a first address queue, and a step of obtaining the cache block, distributing data in the cache block to a corresponding client, and releasing the cache block. According to the video stream cache distribution method, the memory space can be fully utilized, and the smoothness and integrity of a video are ensured. The invention also provides the video stream cache distribution device, a storage device and a processing device with the above effects.

Description

technical field [0001] The invention belongs to the field of video processing, and in particular relates to a method and device for buffering and distributing video streams. Background technique [0002] With the continuous development of video surveillance in the direction of high-definition digitalization, the amount of video data is getting larger and larger, and the configuration requirements for video processing equipment are also getting higher and higher. At present, the front-end devices that process video data are mainly embedded devices, and the resources such as CPU processing performance and memory of embedded devices are often difficult to meet the requirements for processing video data. Therefore, in the case of limited hardware resources of current embedded devices, improving the processing efficiency of its software is one of the effective methods to improve the performance of embedded devices in processing video data. [0003] Video caching is an important ...
