The command:

Verbose log

Usage: youtube-dl [OPTIONS] URL [URL...]

youtube-dl: error: no such option: -m

Description

The --postprocessor-args option appears to be nonfunctional and/or broken.

Invalid first dash character.

Okay, so now I fixed that and it has a different problem.
The new command:

https://www.youtube.com/watch?v=GglsBHdKDBk -verbose --postprocessor-args "-metadata album='x Infinity'"

The new verbose output:

[debug] System config: []
[debug] User config: [u'-f', u'm4a/wav/mp3']
[debug] Custom config: []
[debug] Command-line args: [u'https://www.youtube.com/watch?v=GglsBHdKDBk', u'-verbose', u'--postprocessor-args', u"-metadata album='x Infinity'"]

Long options must start with double dash. Maybe you'll bother checking what you run?

I'm sorry, I don't understand what you mean. What counts as a "long option?"
