使用Python把flv格式的文件转换为mp3格式

目的：想把喜欢视频转换为音频，在手机上听

以下的是转换的关键代码，首先要确保moviepy库是安装成功了。

import moviepy.editor as mp

if __name__ == "__main__":
	clip = mp.AudioFileClip(r'D:\studying\project\python\P.flv')
	clip.write_audiofile(r'D:\studying\project\python\P.mp3')

以下是批量读取指定目录下.flv文件转换为.mp3文件

import moviepy.editor as mp
import os

if __name__ == "__main__":
	#  指定文件目录
    current_address = r"D:\studying\project\python\flvTomp3\src"
    # 获取指定目录下的所有文件
    file_list = os.listdir(current_address)
    for file_address in file_list:
    	# 获取文件名(不包含后缀.flv)
        file_name = file_address.split('.')[0]
        # 拼接文件的绝对路径(dir+xxx.flv)
        file_address = os.path.join(current_address, file_address)
        print("需要转换的文件 >>>>> " + file_address)
        # 调用moviepy库的方法
        clip = mp.AudioFileClip(file_address)
        # 拼接转换后的文件路径
        file_name = file_name + '.mp3'
        out_address = os.path.join(current_address, file_name)
        print("转换后的文件 >>>>> " + out_address)
        ###  
        clip.write_audiofile(out_address)

按常理其他格式也试用吧，等有机会再试吧。
