[Google Plus] Support embedded youtube videos

[ibennetch]

Using the latest version, 2015.11.02 (tested on Mac and Debian Linux) I can't download video from Google Plus:

Using a different URL (which I'd rather not share publicly since it's not mine and isn't public), I get

I'm not sure if the two are related since they're different error messages but both relate to Google Plus.

It's a youtube video that you can download using https://www.youtube.com/watch?v=eieBXGpNYyE. For the second problem, unless you open a new issue with the actual link there's nothing we can do.

[ibennetch]

Sorry, I'm a bit lost; did I miss something with the youtube link -- like is the Google Plus post that redirects to Youtube, or did you just happen to find it mirrored on Youtube?

About the second one, could I send you the link privately? I don't mind sharing it, I'd just rather not post publicly without permission (from a poster I'm unlikely to be able to contact).

No, it's an embedded youtube video. I see the link in the post itself:

Watch here: http://buff.ly/1NVBGHZ

But youtube-dl should probably try to download it. I just gave you the link in case you wanted to download it now.

About the second one, could I send you the link privately? I don't mind sharing it, I'd just rather not post publicly without permission (from a poster I'm unlikely to be able to contact).

I don't have too much time right now, so I would probably forgot. Maybe other developer can do it.

Thanks for the quick help! I appreciate it.
