AI Technical Summary

Technical Problem

Traditional video encoding technology has lag when processing code rate overflow or underflow, resulting in large fluctuations in the code rate, affecting the stability and quality of video encoding.

Method used

By encoding video frames frame by frame, the fill state of the video buffer is detected in real time, and the parameters of the encoding parameter generation model are dynamically adjusted according to the changes in the fill state to avoid code rate overflow or underflow.

Benefits of technology

It effectively reduces the fluctuation of bit rate, improves the stability and quality of video encoding, and ensures the smoothness of video playback.

Abstract

The invention relates to a video coding method and device, electronic equipment and a storage medium, and the method comprises the steps: coding a current frame in a video, and determining a filling state of a video buffer region after coding; adjusting parameters of a coding parameter generation model based on the filling state, the coding parameter generation model being used for generating coding parameters; and generating a new coding parameter based on the adjusted coding parameter generation model, and coding the next video frame by using the new coding parameter. According to the embodiment of the invention, bit rate overflow or underflow can be effectively avoided, and the video playing quality problem caused by bit rate fluctuation is reduced.
