Does anyone know the significance of the very specific wording found in the iPhone 6 specs page?:<p>"FaceTime over cellular uses H.264/H.265" (on US site)<p>"FaceTime over a mobile network uses H.264/H.265" (on UK site)<p>Why would they specify "mobile/cellular"? The only thing I could think of was that the extra compression was worth the trade-offs in battery usage in that case due to the limited bandwidth?<p>Also, it looks like VP9 support may have landed (and been reverted?) into Google's WebRTC codebase in the last week or so:<p><a href="https://webrtc-codereview.appspot.com/27779004" rel="nofollow">https://webrtc-codereview.appspot.com/27779004</a>
