No html5 video/audio support in qt-webkit

[MalleRIM]

Hi,

I don't have any support for audio and video tags in qt-webkit based browsers such as konqueror and rekonq. I don't know when support for this disappeared, but it never worked well anyway (audio worked, video didn't).
html5test.com shows no support and of course it isn't working either. Some people report working html5 video qith qt-webkit, so it's not something that it doesn't support. It's just not working on Gentoo and some other distros.
Where does format support for qt-webkit actually come from?
Regards,
Malle
