attached is a pkgbuild diff for qt that builds qt with phonon. I had to remove 
phonon, phonon-xine and phonon-gstreamer using --nodeps.

I also created a symlink /usr/lib/kde4/plugins/phonon_backend pointing to 
/usr/lib/qt/plugins/phonon_backend/

I also installed gstreamer good/bad/ugly plugins.

After this, webkit built the video support and html5test reports mpeg4/h.264 
but no webm. I can play videos from tinyvid.tv too(which are ogv format). but 
this build of webkit crashes way too many times with the NP-Initialize error. 
So I am not using this for the moment.

Youtube still does not work for some reason. I thought h.264 should work with 
that.

juk works so basic phonon support is working but control center disappears 
after clicking on multimedia. The error logged is 

symbol lookup error: /usr/lib/kde4/kcm_phonon.so: undefined symbol: 
_ZNK6Phonon12GlobalConfig19hideAdvancedDevicesEv


So I guess things are not fully ok and it would require kdelibs rebuild too.

I am now back to webkit bundled with Qt. I guess it will be sometime before 
things work as expected with a webkit based browser.
