使用python+ffmpeg批量转换格式

import os		# 获取目录下的所有文件列表
import fnmatch	# 文件格式筛选模块，筛选指定格式文件
#遍历
def dirlist(path, allfile):  
	filelist = os.listdir(path)
	for filename in filelist:
		filepath = os.path.join(path, filename)
		if os.path.isdir(filepath):
			dirlist(filepath, allfile)
		elif fnmatch.fnmatch(filepath,‘*.wav‘):#判断文件格式
			allfile.append(filepath)
			#allfile.append(‘\n‘)
			print(‘*‘*40,filepath,‘\n‘)
	return allfile

#格式转换
def RunScript(fileList) :
	print(‘hello world start:‘)
	
	readf = open("E:\\py\\readfilename.txt", ‘w+‘) #输出所有读入的文件
	writef = open("E:\\py\\writefilename.txt", ‘w+‘)   #输出所有创建并写入的文件
	
	code = "ffmpeg -i "
	codeMid = "  -acodec  libvorbis "		
	for filename in fileList:
		input = filename
		print(‘*‘*40,‘\n‘,‘Begin input = ‘,input,‘\n‘)
		subname = input.split(‘.‘)
		output = subname[0] + ".ogg"
		finishcode = code + input + codeMid + output
		os.system(finishcode)
		print(‘End output = ‘,output,‘\n‘)
		print(input,file=readf)
		print(output,file=writef)
	print(‘hello world end‘)

	fileDir = r‘G:\SVNworking\trunc\exe\resources\media\audio‘

	dirlist(fileDir,allfile)
	for name in allfile:
