I think this maybe a bug as it works on older chrome and desktop chrome but breaks on current android chrome.
I put together a simple demo with three.js and the webvr polyfill and it works fine on Chrome Desktop (50) and Samsung Browser on Android (Modified Chrome 44) but Chrome 50 on Android does not render the video when rendering for Cardboard.
