[webkit-qt] Android WebKit and HTML5

Hi,

I am trying to get some understanding of Androd+WebKit port, specially
around HTML5 player implementation, I wrote to android-platform list, looks
like my
messages was not loud enough to reach develoeprs. I am hoping to bump into
some
Android+WebKit developers here.

As you might know, android only has full-screen support for HTML5
player. I performed some tests around this, it seems like implementation
does not honor any css
properties applied around video element, which means its
directly scaling video buffer to whole screen. And
implementation is neverwriting back to WebKit buffer; I know from Qt's 4.6
implementation
there are some performance implications around it (since it uses
WidgetRenderer), And in Android,
I am assuming this is done take advantage of hardware-acceleration?

One more questions on same ground; how are controls being rendered
in Android+WebKit?
I know that, in desktop world, layout and rendering of controls are handled
by WebKit rendering engine.

So now I wanted to modify this code, so that instead of displaying full
screen I write it back Webkit buffer
so that my pretty css works around video element. But I am unable to locate
the media player implementation
under directory "mydroid/external/webkit/WebCore/platform/graphics/android"

Does this mean media player implementation (MediaPlayerPrivateInterface) is
vendor
(such as Samsung / HTC / Droid etc) specific?

Does it also mean that codec-support is delegated all the way to vendor
code? Which kind of makes sense.

Thanks
