The video itself is blocked (in some contries?), but the error message does
not display that this is the cause ?

I think the issue here is that the link is NOT to an existing video but rather to an upcoming YouTube Live event (in November 2014). So there is no "video" that can be downloaded.

The way YouTube Live works with "Upcoming Events" is that they run a "countdown" screen in advance of the event. When the event goes live, the URL then shows the live stream. When the event is over, THEN there is an archived recording of the event that could be viewed or downloaded.

I would not expect "youtube-dl" to work in this case because there is technically nothing that can be downloaded right now.

Ah, thanks. My browser displays the message below, which made me assume that
the event is taking place right now, but I'm not allowed to access it:

Live Streaming is not available in your country due to rights issues.
The Adobe Flash Player or an HTML5 supported browser is required for video playback.

Is there any field in some parts of the site/video that would allow youtube-dl to detect that the event has not yet taken place ?

It would be nice to have a clearer error message. I don't usually open youtube videos and only realize that it was an upcoming stream after seeing this issue.

Nowadays proper error message is displayed.
