PyQtMobility problem

bisoftmm

I. Introduction
I want to load QML file with Video element from python file based on PyQt library. I have problem trying to use QtMultimediaKit. I use Windows Vista and I have:

qt-sdk-win-opensource-2010.05.exe
python-2.6.2.msi
PyOpenGL-3.0.1.win32.exe
lxml-2.2.8.win32-py2.6.exe
PyQt-Py2.6-x86-gpl-4.8.4-1.exe
(I also have PySide-1.0.0beta3qt471.win32-py2.6.exe and mutagen-1.20.tar.gz)

II. Problems
II.1. So I decided to try PyQtMobility and I downloaded qt-mobility-opensource-src-1.1.3.zip. There is no qt-mobility-opensource.exe installer so when I tried to install QtMobility I had first problem.
When I compiled QtMobility I needed to configure QtMobility but I found that configure script took all values from sipconfig.py and pyqtconfig.py but I installed all QT and python libs to disk D: and it looks like sipconfig.py and pyqtconfig.py files contain paths point at disk C: and use VC compiler. I changed these files (sipconfig.py and pyqtconfig.py) – now paths point at disk D: and use win32-g++ compiler.
After installation of QtMobility I added Video element to QML file. Here is QML file:

@import Qt 4.7
import QtMultimediaKit 1.1
Rectangle {
width: 850
height: 650
Video {
id: video
anchors.horizontalCenter: parent.horizontalCenter
y: 50
width : 640
height : 480
source: "Butterfly.wmv"
playing: true

}
focus: true
Keys.onSpacePressed: video.paused = !video.paused
//Keys.onLeftPressed: video.position -= 5000
//Keys.onRightPressed: video.position += 5000

}
@

Everything works in QtCreator as well in qmlviewer but in QtCreater “import QtMultimediaKit 1.1" and “Video” element are underlined, like there are some errors. So first question – how could I force QtCreator to recognize installed QtMultimediaKit?

II.2. I made CPP file to load QML file:

@#include <QApplication>
#include <QDeclarativeView>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QDeclarativeView view;
view.setSource(QUrl::fromLocalFile("video.qml"));
view.show();
return app.exec();
}
@

It works well. Then I decided to use Python instead of CPP and I downloaded PyQtMobility-gpl-1.0.1.zip and I configured PyQtMobility (I need QtMultimediaKit only)
python configure.py -n D:\Qt\2010.05\QtMobility\include\ -o D:\Qt\2010.05\QtMobility\lib\ -e QtMultimediaKit
After installation QtMobility (at least I think so) I tried to run python file:

@import sys
import os
from PyQt4 import QtCore, QtGui, QtDeclarative

if name == 'main':

app = QtGui.QApplication(sys.argv)
view = QtDeclarative.QDeclarativeView()


view.setSource(QtCore.QUrl.fromLocalFile&#40;'video.qml'&#41;&#41;

view.show()
sys.exit(app.exec_())

@

But I got error:

video.qml:2:1: module "QtMultimediaKit" is not installed
import QtMultimediaKit 1.1
^

Thus video.qml file works in QtCreator, qmlviewer, CPP file but it doesn’t work in python file.
What I tried as well, I added line to my python file:

@from PyQt4.QtMobility import QtMultimediaKit@

but I got another error:

Traceback (most recent call last):
File "main.py", line 8, in <module>
from PyQt4.QtMobility import QtMultimediaKit
ImportError: DLL load failed: The specified procedure could not be found

I understand that in some DLL file some function missed but I have no idea which DLL and which function. My PATH environment var contains:
D:\Python26\Lib\site-packages\PyQt4;D:\Qt\2010.05\mingw\bin;D:\Qt\2010.05\QtMobility\lib;D:\python26;D:\python26\Scripts;D:\python26\lib;D:\Qt\2010.05\qt\bin; D:\Qt\2010.05\bin
I compared Qt files (QtCore4.dll, QtDeclarative4.dll etc) in 3 directories from PATH and found that QtFiles in these
(D:\Python26\Lib\site-packages\PyQt4, D:\Qt\2010.05\qt\bin, D:\Qt\2010.05\bin) directories have different sizes, why? I tried to remove QT files from D:\Qt\2010.05\qt\bin, D:\Qt\2010.05\bin and after that QtCreator and qmlviewer stoped to work. So it seems to me in qt-sdk-win-opensource-2010.05.exe and PyQt-Py2.6-x86-gpl-4.8.4-1.exe there are different Qt files. And even inside qt-sdk-win-opensource-2010.05.exe there two directories with different Qt files.
Second question - Maybe I didn’t install PyQtMobility (and maybe QtMobility as well) properly? but I don’t know what to do to load QML file with Video element from my python?

Make sure you have all modules necessary to QML, installed inside of the folder imports on you QT path.
On linux the default path is "/usr/lib/qt4/imports" on windows depends of which Qt your python bindings use.

On PySide I know we have a qt copy inside of PySide packages, then make sure if you have copied all QtMobility imports files to the PySide imports folder.

This should works

It's not clear for me, you try to help me with first or second problem?
Actually I would like to use PyQt instead of PySide.
I checked my D:\Qt\2010.05\qt\imports\ folder where there are:
Qt, QtMobility, QtMultimediaKit, QtWebKit

D:\Python26\Lib\site-packages\PyQt4\imports\ folder contains only Qt and QtWebKit.
I copied QtMobility and QtMultimediaKit (from D:\Qt\2010.05\qt\imports) into D:\Python26\Lib\site-packages\PyQt4\imports\ folder. But it doesn't work for me. Any suggestion?
Anybody loaded QML file with Video element from python (PyQT) file?

I was talking about the first problem the QML script.

As a PySide developer I know how this work with PySide. If you have copied the files this should works (I think works for PyQt too).

Ok, if I understood the idea properly, I need to check and compare QT files inside PyQt (PySide) directory and main QT directory where QMLviewer, CPP example work.

The point is: to avoid this kind of error when parsing the QML file:

@
video.qml:2:1: module “QtMultimediaKit” is not installed
import QtMultimediaKit 1.1
@

you must have all necessaries files inside of "imports" directory of you PySide/PyQt installation.
