Problems solved by technology
When the scale of objects to be decoded increases, it is necessary to frequently apply for video memory and frequently release video memory. However, frequent application for video memory and frequent release of video memory will cause performance degradation, thereby reducing the efficiency of video stream decoding

The present application relates to a smart business supermarket scene, and specifically relates to a video stream decoding method, device, computer equipment and storage medium. The method includes: acquiring a video stream to be processed, and performing pre-decoding processing on the video stream to be processed to obtain a video data packet; based on the first load information of the image processor and the second load information of the central processing unit, the Determine the target processor in the device; obtain the data size of the video data packet through the target processor; when there is free video memory space greater than or equal to the data size in the pre-applied video memory pool, cache the video data packet to the free video memory space; through the target The processor performs image decoding processing on the buffered video data packets, and clears the content in the occupied video memory space when the image decoding processing is completed. By adopting the method, the decoding efficiency of video decoding can be improved.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a video stream decoding method, apparatus, computer device and storage medium. Background technique [0002] With the development of science and technology, computer vision (Computer Vision, CV) has a wide range of applications in the field of smart retail. For example, in shopping malls, computer equipment can use computer vision technology to decode the video stream collected by the camera, and obtain the decoded image. As a result, face and human body detection is carried out through the image decoding result to obtain the face and human body trajectory, the passenger flow entering the shopping mall, etc. [0003] Currently, the video stream can be decoded by the GPU. For each object to be decoded, the GPU needs to apply for corresponding video memory, decode the object to be decoded through the applied video memory, and release the applied video memory when d...
