Video stream and/or picture stream data sharing method and device and electronic equipment

Abstract

The invention relates to a video stream and / or picture stream data sharing method and device, electronic equipment and a storage medium, and the method comprises the following steps: obtaining a videostream and / or picture stream of a monitoring system, and decoding the obtained video stream and / or picture stream to obtain decoded data; caching the decoded data in a memory; and respectively sharing the decoded data with a plurality of clients according to received requests sent by the plurality of clients so as to enable the plurality of clients to acquire the decoded data. The embodiment of the invention discloses the video stream and / or picture stream data sharing method and device. Compared with the prior art, the multiplexing rate of the decoded data is improved, the decoding frequencyof the hardware decoding unit in the processor to the same video stream and / or picture stream is reduced, the decoding pressure of the hardware decoding unit in the processor is reduced, and the access path number of the video stream and / or picture stream can be increased under the conditions of not depending on special hardware and not increasing the cost.

Description

technical field [0001] The present invention relates to the technical field of video data processing, in particular to a video stream and / or picture stream data sharing method, sharing device, electronic equipment, and computer storage medium. Background technique [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 access channels of video streams and / or picture streams, you need to expand the external video decoding chip or choo...

[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.
