간단하게 소스 짜봤습니다

파이썬 2.7에서 작동하고 저장할 폴더를 save_dir에 지정해서 쓰면 ㅇㅋ

 
# -*- coding: utf-8 -*-
import urllib
import re
import sys
import time
def	download(url):
	save_dir='D:\\nyan\\'
	try:
		url=urllib.urlopen(url).read()
		url=url.decode('unicode-escape')
		url=urllib.unquote(url)
		url=re.findall('"hd_src":"?(.*?)","',url,re.DOTALL)[0]
		url=url.replace('\\/','/')
		url=url.replace('https','http')
		if 'null' in url:
			print "no hd"
			url=url.split('sd_src":"')[1]
		t=time.localtime()
		f=time.strftime('%y_%m_%d_%H_%M_%S',t)+'.mp4'
		fp=open(save_dir+f,'wb')
		print save_dir+f,
		c=urllib.urlopen(url).read()
		fp.write(c)
		fp.close()
		del(c)
		print 'ok'
	except:
		print "fail:", sys.exc_traceback.tb_lineno, sys.exc_info()[0]

while True:
	download(raw_input('url:'))
