Abstract

The embodiment of the invention provides a video splicing method and device, electronic equipment and a computer readable storage medium; the method comprises the steps: firstly determining a first video stream with the minimum frame rate from a plurality of received video streams, and enabling other video streams with the non-minimum frame rates to serve as second video streams; and writing eachreceived first video frame of the first video stream into a plurality of pre-established storage units according to a preset rule, and writing the second video frame into the current storage unit intowhich the current first video frame is written when the second video frame of the second video stream is received; finally, splicing the second video frame and the first video frame in the current storage unit to obtain a spliced image. In this way, adaptation between different frame rates is achieved while the video frames of the video streams are cached, and the requirement for the memory bandwidth of the device is lowered.

Description

technical field [0001] The present application relates to the technical field of video surveillance, and in particular, to a video splicing method, device, electronic equipment, and computer-readable storage medium. Background technique [0002] In the field of video surveillance, it is often necessary to splice multiple channels of video for centralized display. Different video sources may have different frame rates due to differences in video capture devices or differences in video resolution. When performing video splicing from different video sources, frame rate adaptation is required to achieve video splicing. [0003] In the prior art, the method used for video splicing is to perform first-level frame buffering on the received video streams from different video sources, generally implementing frame buffering in device memory. Then read the cached video frames for frame rate adaptation processing, and then perform secondary frame buffering after the video splicing is ...
