Abstract

The invention can provide the method and device for processing the video data stream, the equipment and the storage medium. The method for processing the video data stream can comprise, but is not limited to, at least one of the following steps: reading a video basic code stream, wherein the video basic code stream comprises a plurality of network abstraction layer units; segmenting the network abstraction layer unit into first data packets, wherein each first data packet comprises a plurality of signal source symbols; taking the first preset number of first data packets as a packet group, and respectively obtaining a second preset number of signal source symbols from each first data packet in the packet group; and performing parallel coding processing on the second preset number of signal source symbols to obtain a second data packet. According to the method, the encoding and decoding processes are comprehensively optimized through two aspects of parallel computing and data access mode optimization, so that the technical purposes of increasing the encoding and decoding processing speed and the like are achieved, and the problem of low encoding and decoding speed is fundamentally solved.

Description

technical field [0001] The present invention relates to the technical field of video data processing, and more specifically, the present invention can provide a method, device, device and storage medium for processing video data streams. Background technique [0002] With the continuous improvement of data transmission speed, the application of encoding and decoding of video data streams is becoming more and more extensive. However, due to the technical limitations of existing codec schemes, the codec process is still too slow to meet real-time performance. Although the speed at which users can obtain effective video data can be improved through indirect methods such as upgrading hardware devices or pre-caching data, these methods will increase costs, and in fact do not solve the objective problems of existing codec technology solutions. Contents of the invention [0003] In order to solve the problem of too slow coding and decoding speed in the prior art, the present inv...
