Avfvideosrc represents an iphone camera or, on mac, a screencapture session. The old API allowed you to select an input device by device index only. The new API adds the ability to select the position (front or back facing) and device-type (wide angle, telephoto, etc.). Furthermore, you can now specify the orientation (portrait, landscape, etc.) of the videostream. https://bugzilla.gnome.org/show_bug.cgi?id=778333
