Abstract

The present application relates to an image recording method, device and storage medium for a spliced ​​display screen, which belongs to the field of image display technology. The method includes: receiving multiple video streams corresponding to a specified video board; performing image synthesis processing on the multiple video streams, Obtain the processed video stream; receive the processed video stream sent by other recording boards in the recording board; re-encode the processed video stream sent by other recording boards and the processed video stream obtained by the specified recording board , to obtain one encoded video stream; it can solve the problem that a recording board has limited resources and cannot record the spliced ​​display screen; since multiple recording boards are used for image synthesis, the processed The video stream is encoded again to obtain an encoded video stream, which can realize the recording of the video stream of the splicing display.

Description

technical field [0001] The present application relates to an image processing method, device and storage medium for a spliced ​​display screen, belonging to the technical field of image display. Background technique [0002] The comprehensive video platform has a wide range of applications in security monitoring, command, emergency dispatch and other fields. The comprehensive video platform can provide applications for large-screen display. In the video recording mode of the integrated video platform, a dedicated video board is usually used as a video recorder to re-encode the input signal to realize the video recording function. [0003] However, a video board has limited resources and usually supports independent windowing of up to 16 layers of images. For the display scene of a large splicing display, the number of image layers that need to be displayed on the splicing display will be greater than 16 layers. At this time, a recording board cannot record the spliced ​​d...
