Ok, made a few test builds. For me, if I use QApplication::setGraphicsSystem("raster");
I can get it to work almost like it was by using

QApplication::setGraphicsSystem("raster");...

No solutions, but I observed that

QApplication::setGraphicsSystem("raster");

also causes landscape rendering to misbehave badly, resulting in something that resembles upside down portrait...

Ok, I didn't have any drm protected assets, I guess this was the problem. Although I don't see why the restoration flag would need to behave differently for drm/non drm case. After all, the...

Hi,

I'm calling

If I use phone built in audio recorder, the high quality version seems to be packed into .mp4 container and is actually a smaller file than the standard quality, which will be a 8000Hz wav file.

Don't know about Qt5, but already in Qt 4.7 QtMultimediaKit seems to have taken over QtMultimedia. For instance QAudioInput headers are in both. My problem is that I can't get QAudioInput to...

There seems to be a conflict between QT multimedia and mobility multimedia.

If I take the spectrum demo application, it uses just

QT += multimedia

and works on Symbian phones.

@kusumk: Nice article. Not my problem though, as my code works with qtcreator, just not alone.

For uyvy conversion there is ARM Neon optimized code http://paste.kde.org/1486/raw/ and example...

Well, race condition is typically a timing problem ;). Thanks for the pointer to multiple examples though.

I have code that works, and very similar code that does not work. I was getting...

When I run my application through Qt Creator everything runs fine.
But if I run it through icon or start with command line, the camera never starts up properly.

I wonder how good is the copy protection for IAP enabled apps?

What are the chances that "paid" version of app appears on warez servers soon after publication?

Now tested and confirmed working. Thanks for the quick response.

Fixed where? If this is supposed to be a server side fix, there is something else as well, as it still fails. Further testing shows that it works for X7 Anna, but not on X7 Belle.

Ok, the next...

Thanks, I'll check it out.

So the following is probably the immediately obvious part:

In testing through RDA it seems that X7 is somehow incompatible with IAP. Both Anna and Belle X7 complained about certicate error when trying to install RDA signed SI package. On my development...

Basic Qt C++ apps should work. For instance you could try downloading http://store.ovi.com/content/114263 (free) and see if that works.
If not, then perhaps factory reset time for your phone.

Is there a way to invoke from my application the phone's default twitter client to post (tweet) a message, a post to facebook, etc?

Is there a way to invoke from my application N9's default twitter client to post (tweet) a message?

Well, me thinks that QDesktopServices::openUrl should start device's default browser/application for the url, which precisely already is grob on N9.

Ok... and how is it supposed to get installed if I do my own application with IAP that I submit to Ovi Store?
If I package just the plain unsigned sis, will the store staff/automaton then...

I unzipped iap_qt_sdk_0.3.1_24.01.12.zip under C:/QtSDK and was I able to successfully compile the TryAndByExample targeting Symbian Anna.

I'm looking at Inneractive's QML SDK sources and I see the following code in adinterface.cpp:
