Hello,

I am using Youtube-dl Embedded in a Python program.

I am trying to avoid to have the errors printed on the console but it doesn't work. Here is what I do, with the option 'quiet':

ydl_opts = {
'format': format,
'quiet': True,
'postprocessors' : [{
'key': 'FFmpegExtractAudio',
'preferredcodec': extension
}]
}

And then (the ID is one parameter of my function) :

with youtube_dl.YoutubeDL(ydl_opts ) as ydl:
info=ydl.extract_info('http://www.youtube.com/watch?v='+ID, download=False)
url=info.get('url', None)

But, when I do that, I still have this kind of error written on the console:
"ERROR: AEyKx1XvCKo: YouTube said: "Beautiful Chinese Music?2?T..."
The YouTube account associated with this video has been terminated due to multip
le third-party notifications of copyright infringement." or "ERROR: AERXBUOVaK0: YouTube said: This video is no longer available because the YouTube account associated with this video has been terminated."

So, I tried another way, with subprocess:
link='http://www.youtube.com/watch?v='+ID
x=subprocess.Popen(['youtube_dl' ,'-g', link], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
url=x.stdout.read().decode()

But it doesn't work as well, I have the error "[WinError 2] The system cannot find the file specified".

I think that the best solution is the first, if it works, because youtube-dl Embedded has been created to avoid the subprocess I think!

Can you please explain me why the 'quiet' doesn't work? Or, if it is impossible to not print the errors with this option, why my subprocess doesn't work?

Thank you in advance!
