编码帧率的动态调整方法、装置、设备和存储介质
By dynamically adjusting the encoding frame rate, based on the current PSNR and the target PSNR, a preset proportional differential algorithm is used to smoothly adjust the encoding frame rate, solving the problem of poor user experience and degraded picture quality caused by uneven encoding frame rate changes, thus improving the user experience of video conferencing.

AI Technical Summary
Technical Problem
Traditional video conferencing software suffers from poor user experience due to uneven encoding frame rate changes and sudden, drastic changes in the image. The instantaneous drop in encoding frame rate also causes a decrease in image quality.
Method used
By determining the average peak signal-to-noise ratio (PSNR) at the current moment, and combining the target PSNR with a preset proportional differential algorithm, the coding frame rate at the next moment is dynamically adjusted so that the difference is within a preset threshold, thereby achieving a smooth change in the coding frame rate.
Benefits of technology
It enhances the user's viewing experience, maintains optimal video quality, and adapts to changes in video content and bandwidth.

Abstract
本发明公开了一种编码帧率的动态调整方法、装置、设备和存储介质。该方法包括：响应于编码触发指令，确定当前时刻的平均峰值信噪比；根据当前时刻的平均峰值信噪比、目标峰值信噪比和预设比例微分算法确定下一时刻的编码帧率调整量；根据下一时刻的编码帧率调整量确定下一时刻的编码帧率，以使下一时刻的平均峰值信噪比与目标峰值信噪比之间的差值在预设阈值内。本实施例解决了现有技术中编码帧率变换不平滑导致用户观看体验差，或在突发剧烈变化的画面中编码帧率瞬间降低所造成的画面质量下降的技术问题，实现了根据当前时刻的平均PSNR和目标PSNR动态调整编码帧率，以达到最优画面质量，提升了用户的观看体验。
