I'm not using the command line utility, rather the Python module.

ERROR: No video formats found

Description

I'm not sure as to why is stopped working, as it was working fine earlier.
Essentially, it's attempting to stream from a URL into a discord voice channel.

I have checked all the URL's that it attempts to play, and they all function in the browser.
None of them are geo-restricted either.

Link that I actively test the bot with: https://www.youtube.com/watch?v=oHg5SJYRHA0
(it's not actually meant to be a rickroll)

Correction, it's working fine now.
I just added the postprocessors tag to the options.

'postprocessors': [{
     'key': 'FFmpegExtractAudio',
    'preferredcodec': 'mp3',
    'preferredquality': '192',
}]
