when chrome.desktopCapture.chooseDesktopMedia will be available in chrome (without using plugins)?

I need to make screencasting + audio and than making videos from them for further download to server (without using extensions / plugins)

As I now, the only way to start showing screen in chrome is via - chrome.desktopCapture.chooseDesktopMedia ( If I am not right, please correct me )

Cannot read property 'chooseDesktopMedia' of undefined - I've read answer to this question and there was said that this (chrome.desktopCapture) API can be used: - via some extension - or by enabling browsers internal flags (As I Know - flag for showing screen isn't available for more then two years after creating of this api - If I am not right, please correct me ) Maybe there is a need to enable some another flags to use this api? I'd made a research - and didn't find which ones.

So,

1. Is it possible to start screencasting without using plugins and without asking user to enable some flags(if they exist) ?
2. If not, maybe, somebody knows when this functionality will be available in chrome ?

1 No; Screen capturing from chrome requires the extension or the command-line flag(--enable-usermedia-screen-capturing)

2 No; not until the mindset changes.

The chrome developers consider screen capturing a big security hole (because to many users click yes to all security prompts). They are making it harder to use intentionally. SSL is required for it and related (webrtc).
