Qt 4.8.0 + WebKit 2.2 + HTML5 Video?

Question

HTML

All from one repository.
Update from off. I can’t repositories - it’s forbidden for the project. Version - commit off. release for 4.8.0.
Compiled for Windows, Linux and Mac.
Under Windows, I assembled QtMultimediaKit from QtMobility. HTML5 Video enabled. Sound tags work.
Here is the problem with the video. I used the site html5test.com, on Windows there is support for the video tag, but there is no support for any video format. Under the other axles there is.
Until I can dig out what is missing. Maybe the web whale itself?
The problem is this - I use QGraphicsWebView, I feed it a link from vimeo. The flash player shows the first frame, but there are no controls. Html5 player shows controls, but cannot play — “oops, something is wrong”.
There is also a graphical object that shows the content inside the iframe, if you feed the same things to it, the flash is not drawn at all.
Obviously something is not collected ... The
question is - what? Or does WebKit 2.2 not support html5 video under Windows?
Maybe you can tell me something about the flash?

Answer 1

They say if you build Qt5 correctly under Windows, then there will be a video!

Answer 2

Installed almost all dependencies for the web kit. Only Win SDK 7.1 was not installed ... and the logs do not say anything understandable ... they say “badly loaded from the Internet”, which one loaded there if I install from a 570 mega image ...
Added a message to webcore\features.pri provided that qt_multimedia from mobility is available. Works, DEFINES+=ENABLE_VIDEO = 1 should work.
However, when I opened the webcore.pro project, I saw a completely disabled piece that implements the video tag.
That is, there is supposedly no definition. Suspicious.
