Extracting audio from a Python script

[CRImier]

• I've verified and I assure that I'm running youtube-dl 2016.09.11.1
• At least skimmed through README and most notably FAQ and BUGS sections
• Searched the bugtracker for similar issues including closed ones
• Question

Hi! I'm trying to extract audio from downloading video while embedding youtube-dl into a Python script. How do I go about that? It doesn't seem to be described in options.py, I've tinkered with postprocessor_args etc. but nothing would help. Is it even possible while keeping youtube_dl embedded? If it's not, how do I go about fixing it? Any pointers?

Best regards,
Arsenijs.

Never mind, solved. Added this to "opts":

  "postprocessors":[
{"key":'FFmpegExtractAudio', "preferredcodec":"mp3", "preferredquality":"0"}]

Will soon send a pull request - there's a bug where you can't send an int as "preferredquality", and though it's certainly something intuitively possible, the error message is anything but helpful.
