Abstract

The invention relates to a non-interference screen recording method. The method comprises the following steps: (S1) loading drive equipment of a virtual video card and a virtual display unit (VDU); (S2) initializing the virtual video card, starting an application program and designating the application program to be displayed on the VDU; (S3) outputting images of the application program and rendering the images into a memory by the virtual video card; (S4) periodically encoding the images in the memory according to a corresponding frame rate; and (S5) storing an encoding result in a video file. The invention further relates to a non-interference screen recording system. In the non-interference screen recording method and the system thereof provided by the invention, recording procedures are performed in a background without interference from other procedures and users, and the images of the application program are directly acquired from the memory without depending on hardware equipment of a computer, thus the recording efficiency is high.

Description

technical field

[0001] The present invention relates to video recording technology in the field of multimedia, and more specifically, relates to a non-interference screen recording method and system. Background technique

[0002] The current screen recording technology is all recording on the desktop, which is realized by means of screenshots. In this way, during the screen recording process, the user cannot perform other operations, because any other operations will be recorded during the screen recording. For example, when recording the playback content of PowerPoint, if the video file is played on the computer, the playback of the video file will also be recorded. Therefore, once this recording method is used, the user is not allowed to perform other operations or run unrelated applications, otherwise it will affect the recorded content and interfere with the current result. Moreover, this recording method relies heavily on the graphics card and sound card of the comput...
