pyav 的 bit_rate 和 average_rate 是什么区别？

bit_rate 是码率

average_rate 是帧率

import av


video_file_path='/Volumes/SanDisk128G/标准视频/XiaoShengKeDeJiuShu_4-1080P.mp4'

with av.open(str(video_file_path), metadata_encoding='utf-8', metadata_errors='ignore') as container:
    stream = container.streams.video[0]
    print(stream.average_rate)
    
    print(stream.bit_rate)

输出结果：
