Why not a boolean? We could move to an enum later if needed.

[whywhat, 2015/06/19 16:00:34]

Done.

[mlamouri (slow - plz ping), 2015/06/18 16:43:22]

I believe this is the origin, not eTLD+1.

Also, not the origin of the media but the origin of the top frame of the tab
containing the media.

[whywhat, 2015/06/19 16:00:34]

Well, the origin doesn't have a simple definition, right?
https://tools.ietf.org/html/rfc6454#section-3.2

Since I get it from originForDisplay though, I could name it that.
Yes, it's tab's/page's origin for display.

[mlamouri (slow - plz ping), 2015/06/22 14:34:17]

Origin has a fairly simple definition:
scheme + subdomains + domain + port.

Maybe getOriginForDisplay doesn't show the port?

[whywhat, 2015/06/23 19:39:10]

It doesn't show the default port for https.

Just for the sake of argument (I changed the name to |origin|)

Still, the origin of a URI can be a globally unique identifier instead:
https://tools.ietf.org/html/rfc6454#section-4
E.g. for file or data URIs (which can still play audio and have our notification
show up).

[mlamouri (slow - plz ping), 2015/06/18 16:43:22]

Why not call it origin?

[whywhat, 2015/06/19 16:00:34]

See above. Also, the MediaCapture notification uses the following code to obtain
the "URL" to display:

https://code.google.com/p/chromium/codesearch#chromium/src/chrome/android/jav...

It's the scheme and host, which roughly matches getOriginForDisplay(..., true);

I guess it could be origin after all :)
