python - --extract-audio equivalent for YoutubeDL class? -


i want extract audio in mp3 format youtube links, can't figure out how without calling youtube-dl command line --extract-audio option. there way within youtubedl class similar examples given here?

here's have far, still creates mp4 file.

import youtube_dl  # download using optimal audio settings ydl_opts = {     'format': 'bestaudio/best',     'postprocessors': [{         'key': 'ffmpegextractaudio',         'preferredcodec': 'mp3',         'preferredquality': '192',     }],     'quiet': true,     'restrictfilenames': true}  ydl = youtube_dl.youtubedl(ydl_opts) ydl.download(['https://www.youtube.com/watch?v=pnt2cy5mwyw'])

clarification: above code generate mp3 file, generates mp4 video file. only want generate mp3.

update: here sample of output when quiet set false:

this code should work fine. output if set quiet false? make sure using latest version of youtube-dl , have ffmpeg/avconv installed. ffmpeg/avconv should in path or can explicitly specify location adding 'ffmpeg_location': '/path/to/directory/containing/ffmpeg/or/avconv' ydl_opts.
