This chrome extension not only captures content of the selected tab, but also provides multi-user peer-to-peer tab-streaming.

index.html

chrome.tabs.getSelected(null, function (tab) {
    var video_constraints = {
        mandatory: {
            chromeMediaSource: 'tab'
        }
    };
    var constraints = {
        audio: false,
        video: true,
        videoConstraints: video_constraints
    };
    chrome.tabCapture.capture(constraints, function (stream) {
        // it is a LocalMediaStream object!!
    });
});

Make ZIP of the directory. Then navigate to Chrome WebStore Developer Dashboard and click Add New Item blue button.
