python 使用 ffmpeg 合并音频+视频

import subprocess

def video_add_mp4(file_name,mp4_file):
    outfile_name = file_name.split('.')[0] + '-new.mp4'
    cmd = f'F:\\FFmpeg\\bin\\ffmpeg -i {mp4_file} -i {file_name} -acodec copy -vcodec copy {outfile_name}'
    print(cmd)
    subprocess.call(cmd,shell=True)

if __name__ == '__main__':
    a = 'D:\\project\\Spider\\B_zhan\\video\\新西游记-唠叨-还是算了吧-到此为止1.mp4'    # 视频
    b = 'D:\\project\\Spider\\B_zhan\\video\\新西游记-唠叨-还是算了吧-到此为止2.mp4'    # 音频
    video_add_mp4(a,b)
