For example: the method for splicing real-time recording videos in multiple ways can divide multiple paths of videos into primary and secondary pictures and combine the primary and secondary pictures into one path of video and record the video in real time.
Specifically, when the method for recording video in real time by all-in-one splicing according to the embodiment of the invention is used, firstly, multi-channel video information of a certain scene of the video to be recorded in real time by all-in-one splicing is obtained, the multi-channel video information can be video information of the same scene, the same time and different angles, and the video information of the same scene and different angles is displayed and decoded to generate multi-channel image data; then, the multi-channel image data of the scene is processed to combine a plurality of screens of the multi-channel image data into a composite image of one screen according to a predetermined layout, for example: the predetermined layout may be a picture-in-picture layout, a nested layout, or a surrounding layout; then, the synthesized image is coded, the coded data is processed into a data frame which can be recognized by a burning device, and then the data frame is sent to the burning device for burning; and finally, repeatedly executing the steps S1-S4 to realize real-time video recording.
Therefore, according to the method for splicing the real-time recorded videos in all-in-one mode, the multiple paths of videos are divided into the primary pictures and the secondary pictures and combined into one path of video through the video splicing technology, the picture overlaying technology and the dynamic coding technology, the real-time recording of the video streams can be realized by using the single recording machine, the size of the video data is reduced, the multiple paths of pictures are integrated in one picture in real time, and the multiple paths of pictures are displayed simultaneously during playback, so that scene reproduction can be realized.

The multi-channel video is integrated into one picture in real time, and the multi-channel pictures are displayed simultaneously during playback, so that scene reproduction can be realized.
According to an embodiment of the present invention, step S3 includes: s31, preparing the recording device, detecting the maximum recording speed of the optical disc, and converting into code rate; s32, carrying out image coding on the synthesized image according to the code rate; and S33, organizing and packaging the coded data into data frames which can be recognized by the recording device according to the standard PS format.
