Porting WebKit with video support

Hi,


I'd like to add HTML5 video support to the DirectFB WebKit port on a STLinux STB.
Would you have some pointers or some help on how is designed the interface between video decoding capabilities and WebCore integration ?
I'm suppose there is some kind of "prototype" to extend audio/video support to WebKit ports (and I also assume that this "prototype" is used to bind QTKit with WebCore on OSX or DirectVideo with WebCore on Windows...)


Thanks a lot for your help.

Antoine

Need help in compiling under ubuntu 10.10 RC

Hi,

I am trying to compile webkit source under ubuntu 10.10 rc.

But I am getting this error when I run make. When I run 'configure',
it completes successfully.

$ make
CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash
/media/EXTDIV/WebKit-vanilla/autotools/missing --run aclocal-1.11 -I
autotools
aclocal-1.11: aclocal: file `autotools/lt~obsolete.m4' does not exist
make: *** [aclocal.m4] Error 1

Thank you for any help.

webkit gtk memory leaks

Dear All,

    We are working on webkitGtk( ( with gtk-directfb backend )  and ported for MIPS platform. We observed there are memory leaks with PNG/JPG image rendering. I am using webkit-1.2.0 version and i set cache model to WEBKIT_CACHE_MODEL_DOCUMENT_VIEWER.

When I am rendering the 1.3MB PNG image it is consuming around 7MB memory but after deletion I observed that around 1.3MB memory leak. I enabled cache dumpstats but there is no images cached.

could you please suggest me is there any patch to avoid image related memory leaks with webkitGtk.

Please find the attached sample html which i am using

Thanks In Advance.

Re: Porting WebKit with video support

Look at WebCore/platform/graphics/MediaPlayerPrivate.h
The platform is expected to implement a MediaPlayerPrivate class
You can refer WebCore/platform/graphics/<gtk/qt/win>/MediaPlayerPrivate<Gtk/Qt/QuickTimeWin>.cpp for reference implementations on how its done.

I suppose you are already running Webkit using Gtk or Qt on DFB ? or is it the just announched DFB-lite port of Webkit ?

Re: Porting WebKit with video support

Thanks a lot for your reply. I'll have a look at the internals of MediaPlayerPrivateXXX.

FYI, I use the QT port of webkit.

Spatial Navigation

Hello All,
             I am not able to get the focus on the Map Tag and Area Tag, using spatial navigation. I had tried to get the co-ordinates for the elements having Map/Area Tag using the function :
IntRect HTMLAreaElement::getRect(RenderObject* obj) const
 
but its returning incorrect value.
Pls guide me on how to proceed on this, as Maps and Area Tag are not handled in Spatial Navigation.
 
Regards,
Umesh

Re: Spatial Navigation

Hi Umesh.

Could you please file a bug against bugs.webkit.org and attach a
simple test case for the bug? I would be glad to implement this
support, or help out somehow.

Please paste the bug URL here.

webstorage data model

Hi all,
I am currently interested to explore the low level data storage model used
in html5. My primary aim is to study the physical organization of the
records with custom attributes, the key-value relationship, and how the
queries interact with such a data model. And if possible develop some
caching techniques to enable faster access of data to the APIs.

I have been trying to find some documentation on this but could not make
much progress. So can anyone give me some pointers where to start from?

Any help is highly appreciated.

Thanks,
subhadip
