youtube_dl.utils.ExtractorError: Content Warning

Description

Same question, other age-gated content works, except this one.

glenn-slayden · 2019-07-30T20:41:37Z

This is a case of reporting a misleading status message. The error message it shows in this case is actually a warning, and not a fatal error, but it's from beyond the age-gate page. And it turns out that there's a more pressing failure, so the inability to download is real.

The true error, which youtube-dl should probably report instead. is likely:

Watch this video on YouTube. Playback on other websites has been disabled by the video owner.

The problem is that the age_gate code path doesn't check for such error messages. Instead the operation fails later upon discovering that there is no actual video url (or dash manifest) to download. In other words, the error message you're getting is actually just the warning that would apply if you did "watch this video on YouTube."

To fix the error message, insert the following three lines into extractor/youtube.py:

youtube-dl/youtube_dl/extractor/youtube.py

Lines 1728 to 1735 in c2d125d

    
           video_info_url = proto + '://www.youtube.com/get_video_info?' + data 
        
           video_info_webpage = self._download_webpage( 
        
               video_info_url, video_id, 
        
               note='Refetching age-gated info webpage', 
        
               errnote='unable to download video info webpage') 
        
           video_info = compat_parse_qs(video_info_webpage) 
        
           pl_response = video_info.get('player_response', [None])[0] 
        
           player_response = extract_player_response(pl_response, video_id)

    +     player_status = player_response.get('playabilityStatus')
    +     if 'reason' in player_status:
    +         raise ExtractorError(clean_html(player_status['reason']), expected=True)

youtube-dl/youtube_dl/extractor/youtube.py

Lines 1736 to 1737 in c2d125d

    
           add_dash_mpd(video_info) 
        
           view_count = extract_view_count(video_info)

Actually, it turns out that those three lines are applicable to the non-age-gated code path as well. So it would be even better to insert them here instead:

   +     player_status = player_response.get('playabilityStatus')
   +     if 'reason' in player_status:
   +         raise ExtractorError(clean_html(player_status['reason']), expected=True)

youtube-dl/youtube_dl/extractor/youtube.py

Lines 1813 to 1817 in c2d125d

    
           def extract_unavailable_message(): 
        
               return self._html_search_regex( 
        
                   r'(?s)<h1[^>]+id="unavailable-message"[^>]*>(.+?)</h1>', 
        
                   video_webpage, 'unavailable message', default=None)

glenn-slayden · 2019-08-05T18:43:45Z

ping @dstftw -- this is an easy 3-line fix if you want to adopt it...

Besides giving a more correct error message for age-gate failures, this change also makes youtube-dl abandon those cases earlier on, which avoids further wasted effort extracting metadata.

dstftw · 2019-08-05T19:23:01Z

Watch this video on YouTube. Playback on other websites has been disabled by the video owner.

is as useless and incorrect as the current one.

The real error in my case is

Sign in to confirm your age
This video may be inappropriate for some users. Confirm and download?

glenn-slayden · 2019-08-05T20:31:42Z

Thanks. That's why you're the expert.

diamondsw · 2019-08-22T13:43:20Z

Before I post what may be a duplicate, is it expected behavior now that certain age-gated videos cannot be downloaded without logging in? I thought previously youtube-dl had ways of bypassing such checks.

rebane2001 · 2019-08-24T22:14:11Z

@diamondsw Youtube-dl bypasses it by doing (this is my assumption) /embed/
This means that if the video does not allow playback on other websites, it won't be downloaded and you HAVE to sign in

salamihawk · 2019-12-02T09:26:51Z

Despite the commit on Aug 5, this issue still persists.

I'm calling Youtube-DL via an import into a script of my own. I'm setting login data and passing it to youtube-dl. This appears to work fine for most videos, but age-gated videos with embeds disabled refuse to work.

Tests by calling youtube-dl directly from the command line are also unsuccessful.
