Method, device, equipment and storage medium for balancing video frame rate error

Abstract

The present invention is applicable to the technical field of video processing, and provides a method, device, device and storage medium for balancing video frame rate errors. The method includes: detecting the video display frame rate of the video display terminal when displaying the current video frame and the Corresponding to the frame rate error accumulation between the video acquisition frame rates of the current video frame, when the frame rate error accumulation reaches the preset accumulation threshold, it will be used for the video display end to send the video frame transmitted by the video acquisition end to the video display Switch the current display timing parameters displayed by the display device connected to the terminal to another set of display timing parameters, and continue to detect the accumulation of frame rate errors at both ends of the video display terminal and the video acquisition terminal to determine whether to adjust the display timing parameters of the video display terminal. Switching, so as to realize the effect of using the frame rate jitter, balance the average frame rate of the display, make the frame rate of the video acquisition end and the video display end consistent, greatly reduce the cache cost, and improve the real-time performance of video transmission.

Description

technical field [0001] The invention belongs to the technical field of video processing, and in particular relates to a method, device, equipment and storage medium for balancing video frame rate errors. Background technique [0002] With the development of society and the advancement of technology, people have higher and higher requirements for real-time video display. For example, using a car camera to replace the exterior rearview mirror to observe the scene of the road outside the car requires a car display device that can display the car camera in real time. Get the video of the road conditions outside the car to improve driving safety. However, during the process of video acquisition to display, there is an error in the video frame rate at both ends due to the frequency error of the clock source at the video acquisition end and the video display end. If this frame rate error is not eliminated, due to the cumulative effect, it will cause video Acquisition and display c...
