Abstract

Embodiments of the present invention provide a screen recording method, and a screen recording control method and device. The screen recording method comprises: receiving a control message sent by the screen recording control device; and sending to the screen recording control device image information of the device at a recording start moment and a graphics instruction enabling the image of the device to change within the recording time, the device being a device whose screen is being recorded, the recording start moment being a recording start moment indicated in the control message, and the recording time being a recording time indicated in the control message. The present invention reduces occupied physical space and transmitted data amount in the screen recording process, and meanwhile lowers the bandwidth requirements in the recording process.

Description

technical field [0001] Embodiments of the present invention relate to the field of information technology, and in particular, to a screen recording method, a screen recording control method, and a device. Background technique [0002] Screen recording (Screen Record, SR for short) is generally used to record and save the changed content (including user operations and video playback, etc.) displayed by a computer within a period of time. Screen recording is currently a common method for making various screen recordings or video monitoring. [0003] The existing screen recording method is to capture the frame image on the screen through the API interface provided by the operating system within a period of time, for example, the interface provided by the GDI engine of the Windows operating system can be called to capture the frame image on the screen, and then the captured Frame images are stored on disk as a video stream. Users can watch the screen changes during this period...
