Description
Technical Field
The invention belongs to the technical field of cloud rendering, and particularly relates to a cross-process independent cloud rendering method, device, equipment and storage medium.
Background
There are two techniques similar to the present invention on the market. The first is a cloud rendering technology of each big game engine, and the technology mainly comprises the steps that a game engine bottom layer transmits a self-rendered picture to a Web end through a video coding and decoding module and a network communication module which are developed by the game engine bottom layer. The technology has the defects that the technology is tightly connected with an engine, when an abnormality is triggered in the cloud rendering process, the whole program is crashed and exits, and the restarting time is long and the operation state in the running process is easy to lose. The second is a completely independent cloud rendering technique, which has two main implementations. One is to acquire a process handle by acquiring a process ID of a program in a computer, and after the process handle is positioned to a corresponding program window, capturing pictures in the whole program window and carrying out coding transmission. The disadvantage of this approach is that the step of capturing the picture of the program window occurs on the CPU, taking up the CPU computing power and increasing its consumption with higher program resolution, exacerbating the hardware load pressure on the server. Another way is to implement the picture taking by injecting hook. The main application scene is a live game screen. Since the picture data of the target program cannot be directly acquired, the picture is acquired by an external code injection method, which has the defect that the time of dll injection needs to be strictly controlled, and if the basic picture rendering initialization of the target program is later, the problem of injection failure can occur. Meanwhile, the method is still a rendering process of the monitoring target program, and the CPU computing capacity is occupied to acquire the picture data.
