Pluginfree-Screen-Sharing.html

1. your online Pluginfree-Screen-Sharing.html Works! Congratulations
2. The file of that name in your github directory is not the same file (it attempts video)
3. Even when I use the online version of Pluginfree-Screen-Sharing.html on my own server, it doesn't work. (The button does nothing. And the private link goes back to google drive).
4. Help?

Test it on HTTPS. Because, screen capturing (currently) only works on SSL domains.

Chrome denies request automatically in the following cases:

1. Screen capturing is not enabled via command line switch.
   mandatory: {chromeMediaSource: 'screen'} must be there
2. Audio stream was requested (it's not supported yet).

navigator.webkitGetUserMedia({
    audio: false    /* MUST be false because audio capturer not works with screen capturer */
});

1. Request from a page that was not loaded from a secure origin.

Here is their C++ code that denies screen capturing:

if (!screen_capture_enabled ||
    request.audio_type != content::MEDIA_NO_SERVICE ||
    !request.security_origin.SchemeIsSecure()) {
        callback.Run(content::MediaStreamDevices());
        return;
    }

Personally I don’t know why they deny non-SSL requests. Maybe they’re using iframes in sandbox mode or something else that runs only on HTTPS.

Browsers who don't understand {chromeMediaSource: 'screen'} constraint will simply get video like chrome stable or Firefox.

Can you explain what you meant by "The file of that name in your github directory is not the same file"?

Corrected. Thanks.

What I meant is that these two HTML files are very different (and do different things)
