from future import unicode_literals
import youtube_dl

class MyLogger(object):
def debug(self, msg):
pass

def warning(self, msg):
    pass

def error(self, msg):
    print(msg)

def my_hook(d):
if d['status'] == 'finished':
print('Done downloading, now converting ...')

ydl_opts = {
'format': 'bestaudio/best',
'postprocessors': [{
'key': 'FFmpegExtractAudio',
'preferredcodec': 'mp3',
'preferredquality': '192',
}],
'logger': MyLogger(),
