I haven't use the VA-API plugins yet but my guess is that a custom
video-sink is created (like in the VDPAU case) and the webkitgtk
video-sink that handles the "in-webview" rendering is simply ignored :(

Not sure we can do much about this, our sink would need to support
video/x-vaapi-surface and be able to convert the VA-API surface to a
Cairo surface.

I'd better wait GStreamer 1.0 which plans to better support and somehow
unify the various APIs for HW-decoding (VDPAU, VA-API, etc.).
