Video recording device and method

Abstract

The invention provides a video recording device and method. The video recording device and method are applied to a host of a user. The video recording device comprises a DLL injection unit, an interface establishment unit, a function replacement unit and a function call unit. The DLL injection unit is used for injecting a DLL into a target process, wherein the DLL comprises a video capture DLL. The interface establishment unit is used for establishing a Direct device interface. The function replacement unit is used for replacing a drawing function in the target process with an address of an image capture function in the video capture DLL. The function call unit is used for calling the image capture function to acquire pixel data of an image to be drawn in a background buffering process before the drawing function is called by the target process every time. Compared with the prior art, the video recording device and method have the advantages that API HOOK can be conducted on drawing functions of various Direct versions, as a result, image data on a display card can be acquired, the purpose of reducing resource consumption of a CPU, an internal storage and the like is achieved when full-screen game video is recorded, and better service experience is provided.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a video recording device and method. Background technique [0002] With the development of the electronic game industry and the surge in the number of game players, players also have various needs for game experience, one of which is to record the game screen as a video, save it locally or upload the video to the server for live broadcast, for players Exchange between use. At present, some software that can provide game video recording function mainly include yy game live broadcast plug-in, Fraps, XSplit and so on. [0003] Since the live broadcast of the game requires synchronous video recording while the game is running, the above-mentioned software will take up a lot of CPU and memory when recording video after the game starts, reducing the system running speed, resulting in game freezes, frame skipping, etc. question. This will not only fail to record video normally...

Problems solved by technology

[0003] Since the live broadcast of the game requires synchronous video recording while the game is running, the above-mentioned software will take up a lot of CPU and memory when recording video after the game starts, reducing the system running speed, resulting in game freezes, frame skipping, etc. question

This will not only fail to record video normally, but may also cause the running game process to be stuck

It can be seen that the existing technology does not fully consider the user's requirements for service experience. In applications such as online games, service experience such as response delay and picture quality is very important to users.
