error in python module YoutubeDL fileno = out.fileno()

[carvalhomr]

Thank You for the great app;
But now I´m having some troubles in using youtube-dl as python module. I´ve updated my last version in 05.01.2015. Since then i get the same error over and over and couldn´t download any file any more.
Can you help me ?

Here´s the error:

from youtube_dl import YoutubeDL
ydl = YoutubeDL()
ydl.add_default_info_extractors()
nfo =ydl.extract_info('http://www.youtube.com/watch?v=giNdyLY46Mo')

UnsupportedOperation: fileno

It looks like the same error as the one you posted some time ago: #2820. It should have been fixed with a383a98.
@phihag: out.fileno() seems to raise UnsupportedOperation, shouldn't we catch it instead of AttributeError?

@jaimeMF Pseudo-files don't have fileno in the first place, so we should catch both conditions.

I cannot reproduce this strange error (even on Windows), but we can simply catch it and fall back to the default output stream. I've done exactly that in youtube-dl 2015.01.23.3. I'd appreciate feedback of whether this has fixed your issue.
