extract_info() returns forbidden urls (403)

[romaincointepas]

This happens with some videos (like this one: https://www.youtube.com/watch?v=m1ET6SEtwbc)

I think it's never doing the _extract_signature_function() things (available in youtube extractor) when doing extract_info().

It works fine here, how are you getting the information? are you using your own server?

[romaincointepas]

I'm on Appengine python. On your side, the 'url' field doesn't return a 403 ? Are you getting a 'player_url' field as well ?

[jaimeMF]

The url can be played fine on Firefox, mpv and I have downlaoded it with curl. I also get the player_url field, but I don't think that's a problem. I've looked in the logs and the signature extraction seems to be run. Are you selecting a specific format or the url from the main dictionary?

Here is how I'm reproducing:

import sys
import webapp2
from google.appengine.api import urlfetch
import json
import youtube_dl

####################################################################

if not hasattr(sys.stderr, 'isatty'):
    sys.stderr.isatty = lambda: False

class SimpleYDL(youtube_dl.YoutubeDL):
    def __init__(self, *args, **kargs):
        super(SimpleYDL, self).__init__(*args, **kargs)
        self.add_default_info_extractors()

class Test(webapp2.RequestHandler):

    def get(self):

        video_id = 'm1ET6SEtwbc'

        ydl = SimpleYDL()
        info = ydl.extract_info(video_id, download=False)

        best_format = info['formats'][-1]

        stream_url = best_format['url']

        result = urlfetch.fetch(stream_url)
        response = {
            'url': stream_url,
            'status': result.status_code
        }

        self.response.headers['Content-Type'] = 'application/json'
        self.response.out.write(json.dumps(response))

####################################################################

app = webapp2.WSGIApplication([('/', Test)], debug=True)

I get a 403 with this video: m1ET6SEtwbc, and a 200 for this one: YP2BZc70pmQ (same thing with all formats).

I'm using __version__ = '2014.03.27.1' of youtube_dl

Do you have any log produced by the app?, Have you tried setting the cachedir param and monkey patching?

If you can't reproduce it with my code I will close the issue.

Closing due to lack of information.
