Problems solved by technology

[0002] Some clients, such as video playback clients and AI data processing clients, need decoded data. Since video stream and / or image stream decoding requires a lot of computation, the hardware decoding unit in the processor is generally used for video stream and / or image stream decoding. or picture stream decoding, in the prior art, the hardware decoding unit decodes the acquired video stream and / or picture stream multiple times to send the decoded data to multiple clients respectively, but the hardware decoding unit capability in the processor It is limited. If you want to increase the number of video streams and / or picture streams, you need to expand the external video decoding chip or choose a processor with a higher specification, which increases the related costs.

Abstract

The present invention relates to a video stream and / or picture stream data sharing method, device, electronic device, and storage medium, wherein the video stream and / or picture stream data sharing method includes: acquiring the video stream and / or picture stream of the monitoring system and Decoding the acquired video stream and / or image stream to obtain decoded data; buffering the decoded data in memory; and sharing the decoded data, so that the multiple clients can obtain the decoded data. The method for sharing video stream and / or picture stream data in the embodiment of the present invention improves the multiplexing rate of decoded data, reduces the number of decoding times of the same video stream and / or picture stream by the hardware decoding unit in the processor, The decoding pressure of the hardware decoding unit in the processor is reduced, and the number of access channels of video streams and / or picture streams can be increased without relying on special hardware and without increasing costs.
