Abstract

The invention is applicable to the technical field of computers, and provides a frame rate adjustment and apparatus, and a terminal device. The method comprises the following steps: obtaining a pixelvalue of a current image frame in a video, and calculating a differential value of a change degree of the current image frame; calculating the differential value of the change degree of a subsequent image frame in the video; generating an image differential recording; calculating an image change evaluation value of the subsequent image frame according to the image differential recording; and if the image change evaluation value is not within a preset threshold range, adjusting the receiving frame rate of the subsequent image frame. The change degree of the next frame image in the video is estimated according to the differential value of the change degree of each frame image in the received video within a period of time so as to automatically adjust the receiving frame rate of the subsequent image frame, so that the error of manually adjusting the frame rate by the user can be avoided, when the image change is relatively small, a relatively low frame rate can be adopted to reduce the bandwidth and resource occupancy shared by the screen without affecting the user experience, thereby reducing the traffic cost of a service provider.

Description

technical field [0001] The present application belongs to the technical field of computers, and in particular relates to a frame rate adjustment method, device and terminal equipment. Background technique [0002] The process of screen sharing includes the collection, encoding, transmission and decoding and rendering of the shared terminal screen, such as figure 1 shown. In order to obtain a good sharing effect during screen sharing, high resolution and high frame rate are generally set. For end users, high frame rate video will occupy a large amount of bandwidth and terminal CPU performance, which may affect the operation of other applications; for service providers, high frame rate video will inevitably lead to high traffic and high costs; And for static scenes with relatively small screen changes, a high frame rate is not required; for dynamic scenes with relatively large screen changes such as shared media videos, the frame rate needs to be appropriately increased. Wh...
