Snagit Chrome扩展技术

Question

I need to create a cross-browser extension that can detect locally active windows. Recently I came through Snagit Chrome extension where clicking on "Screen" detects the active windows of the system and allows to capture any desired screen.

Can anyone please explain the platform/tech used to detect or get the window handles from browser app? or any other way to get the handles..

Thanks

I was finally able to get the technology used in SnagIt extension.
SnagIt has used "WebRTC desktopCapture" for the same.

A sample can be found here .

WebRTC supports Chrome and Firefox for now. The desktopCapture feature enables user to share screen and this frame can be captured for screenshot as well. Frame capture example can be seen here
