Hi,
We are developing a camera application on Windows 8, quick 1.1, qt 5.2. We
attempted to use qcamera with our usb camera. The camera supports two
resolutions.
How can one set the desired resolution for streaming? The user of this
application will have a drop down to select resolution and

First chameleon waits for another, i.e. he doing nothing while another will not
come to the meeting place. And here semaphore is not necessary.
Most slow place is QEventDispatcherWin32::processEvents()

"first chameleon should wait a second;" this sound like semaphore to me,
but I don't know this chameleon problem.
What part of Qt is causing it to be slow ? QThread ? the signal/slot ?

Good Day All,
I am using the following code to open and display html content.
void MyClass::playHtml(QString filePath, int w, int h) {
QUrl url = QUrl::fromLocalFile(filePath);
mWidget = new QWebView(this);
mWidget->page()->mainFrame()->setScrollBarPolicy(Qt::Horizontal,
Qt::ScrollBarAlways

Hi,
Why do you need to use Qt signals/slots ?
Isn't there something more appropriate to this task ?

Hi guys,
I have one question to you. Why new syntax of QObject::connect() improve
performance for a 5%.
I mean that if in code change
connect( sender, SIGNAL( signal() ), receiver, SLOT( slot() ) );
to
connect( sender, &Sender::signal, receiver, &Receiver::slot );
then code works faster... W
Hi Nurmi,
It is great to know that! That will be part of Qt Widget or Qt Quick
framework?

I installed the codec you suggested. Internet Explorer can play youtube
videos and also Qt seems to be able to play webm video files (tested with
the qmlvideo example). Anyway, the same behaviour occurs with the Youtube
View example. Still no video. I tested with both the ANGLE and OpenGL
version.

to be removed fairly soon and it is now a redirect to to the "qt-5.3"
directory: http://doc-snapshot.qt-project.org/qt5-5.3
This change is due to the new branch scheme. The redirect is se
