Description

When I try to download a video from a facebook group I get an "Unsupported URL" error. Example:

$ youtube-dl https://www.facebook.com/groups/AustinDrones/posts/4493415057345664/
[generic] 4493415057345664: Requesting header
WARNING: Falling back on generic information extractor.
[generic] 4493415057345664: Downloading webpage

ERROR: Unsupported URL: https://www.facebook.com/groups/AustinDrones/posts/4493415057345664/

Superficially, #26975 seems like a similar issue but the error is distinctly different. #12055 look similar, as well, but again, different error and that ticket i super old anyway

I have the same issue ... video plays immediately in browser.

Eg:

chris@aranda:/media/chris/One Touch/Economics/Co-ops $ youtube-dl https://www.facebook.com/watch/live/?ref=watch_permalink&v=569618817495716 [1] 23609 chris@aranda:/media/chris/One Touch/Economics/Co-ops $ [generic] ?ref=watch_permalink: Requesting header WARNING: Falling back on generic information extractor.
