yt broken: Unable to extract JS player URL

[samiq]

Hi guys,

I have the youtube-dl running as a web service on an app engine to which an an app I've built requests the urls of yt videos people want to play so they can be streamed

from time to time, when google changes the signatures, this will stop working, I update with the new code and all keeps working

today the service stopped working, I don’t know if this has been caught as google changing the signatures or something else but the service is failing on me with

An error happened while fetching video '7Ya2U8XN_Zw' with: ERROR: Unable to extract JS player URL; please report this issue on https://yt-dl.org/bug . Make sure you are using the latest version; see https://yt-dl.org/update on how to update. Be sure to call youtube-dl with the --verbose flag and include its complete output.

now, I try to get the same video from my mac's terminal and it works just fine.

it's the same code running on both ends and it's the latest here in github, don't know if some can't help me debug this or has encountered something like this before

Post the full output you get when running with --verbose option.

*.dump files obtained with --write-pages would be helpful as well.

thing is that in my mac (UK) is working, but in the server is not (US) same code... now I just found out about this http://venturebeat.com/2015/01/27/youtube-ditches-flash-for-html5-video-by-default/ don't know if it's related and I am still getting the old html here in UK vs US. I will try to see how I can dump the pages from the server, since in app engine I can't do that

Ok guys was able to get the dump for here in UK and for the one the server is getting:

https://www.dropbox.com/sh/q0ei3la3ta8pzoa/AAAbI3u1CSJ0cDG_QfkpPs31a?dl=0

both files are different, the one I'm getting here in the uk has the assets, js line that is searched for in line 1020 of the code as in

jsplayer_url_json = self._search_regex(
                        r'"assets":.+?"js":\s*("[^"]+")',
                        embed_webpage if age_gate else video_webpage, 'JS player URL')

where the one the server is getting doesn't as is where it breaks the code, so I'm guessing google did change the way html exists

appreciate the help and hope this info helps you guys fixing it

Probably it's the same as #4717, in the page from US I see this message:

<h1 id="unavailable-message" class="message">
    The uploader has not made this video available in your country.
</h1>

We should detect it and report an error (assuming that this is the message you actually get when accessing the page in a browser from the US).

I don't know. Everything was working fine and out of the blue this afternoon all videos went blank. So I don't think is the same issue, as it would have gone blank from before. Something changed in the pages google serve that broke the scripts. I can see it in the logs of my server

Notably, the error messages are a red herring. Can you provide a proxy at a problematic location? (in private is fine). Without a proxy, I don't think we'll be able to adapt the extractor.

I believe this issue to be fixed in youtube-dl 2015.01.30.2, where we look in the embed page as well. I'm assuming the new version fixes the problem for you, but if it doesn't (or even if it does), please report back. We will reopen this issue then if necessary. Thanks for the report!
