Description of your issue, suggested solution and other information

I cannot download from 1und1.tv (a Zattoo partner site) because the session cannot be opened. The output says "Unable to download webpage: HTTP Error 404", see log file. I investigated a bit. youtube-dl uses the Zattoo extractor for this site: class EinsUndEinsTVIE. At line 65 a request to [HOST]/zapi/v2/session/hello is made to initiate a session:

        self._request_webpage(
            '%s/zapi/v2/session/hello' % self._host_url(), None,
            'Opening session', data=urlencode_postdata({
                'client_app_token': app_token,
                'uuid': compat_str(uuid4()),
                'lang': 'en',
                'app_version': app_version,
                'format': 'json',
            }))

This URL path is not correct for 1und1.tv - the /hello part is not needed, see attached screenshot from Chrome dev tools:

In my opinion, this could be fixed by removing the /hello part from line 65 of the zattoo extractor like this:

        self._request_webpage(
            '%s/zapi/v2/session' % self._host_url(), None,
            'Opening session', data=urlencode_postdata({
                'client_app_token': app_token,
                'uuid': compat_str(uuid4()),
                'lang': 'en',
                'app_version': app_version,
                'format': 'json',
            }))

The question is, how would other partner sites supported by the Zattoo extractor be affected by this change, if at all. Or can this be done only for EinsUndEinsTV in any way?

Of course you are not allowed to make any changes that will alter the behavior of existing code. What you must do is to implement some basic polymorphism for session part of URL.

Hi @dstftw,

thanks for the quick reply.

It's perfectly clear to me that it's not an option for the general code. I just wondered if I could do it only for myself and build youtube-dl with that change just for myself, as I only use EinsUndEinsTV from the Zattoo extractor.

In the meantime I fiddled around a bit with Fiddler (what a pun :-D ) and found out that changing the hostname from 1und1.tv to www.1und.tv in the EinsUndEinsTVIE part of the zattoo extractor is enough to get things working.

This would be the minimal possible change in the code to fix the problem. Could someone do that please? In the current state, the EinsUndEinsTV part isn't functional anyway.

Besides, great work!!!

Wow! That was fast! 👍
When is the next release expected? I'm not urging, just asking... Or are there nightly builds somewhere? 😄
