The invention discloses a method, equipment, computer equipment and a storage medium for splicing screen recording, wherein the screen recording parameters are obtained, a data sending thread and a data receiving thread are created according to the screen recording parameters, and a shared buffer corresponding to the data sending thread is allocated Memory, according to the screen recording parameters, frame and zoom the single-screen target video to obtain the returned data, send the returned data through the data sending thread, and receive the returned data through the data receiving thread, wherein the returned data has the same characteristics as the single-screen One-to-one corresponding serial numbers, the returned data is fused to obtain video data, and the video data is stored according to the preset path. Among them, the fusion includes framing, frame synchronization check and encoding, which solves the need to add hardware for splicing screen recording, resulting in For the problems of complex operation and high cost, this method realizes the recording of splicing screen fusion images from the software level, without additional hardware resources, and reduces costs.
Description
technical field [0001] The present application relates to the field of display technology, in particular to a method, device, computer device and storage medium for splicing screen picture recording. Background technique [0002] With the development of display technology, splicing screens appear in daily life. The splicing screen is a complete LCD splicing display unit, which has the advantages of super long life, large viewing angle and high resolution. With the development of splicing screen technology, splicing screen It is more and more widely used in daily life, and users have more and more requirements for the display content and display methods of the splicing screen. On the other hand, in public security command centers, building control and monitoring centers and other occasions, users need to record and store the display content after the comprehensive layout of the splicing screen, that is, multi-screen splicing screen recording. [0003] In the related technolo...
