Camera Problem on Symbain^3

alexander

use Symbian C++ in Qt

chriadam

Hi,

See the docs for the camera-related classes in the Multimedia module of Qt Mobility 1.1.0.
http://doc.qt.nokia.com/qtmobility-1.1/multimedia.html#camera-support

The API and implementation has been finalised I believe (it's not beta) but I don't know whether the smart installer supports it yet (which would impact availability on Ovi Store, I think).

Cheers,
Chris.

QtMobility 1.1.0 is not accepted in to Ovi Store. Probably won't be until next year when Qt4.7.2 is allowed.
So you'll have to take the advice of Alexander here and make do with Symbian C++.

However, if you don't mind waiting until next year the Camera API will be much easier and quicker (although sort of defeats the point when you need to wait ;) ).

By the way, I think they may be replacing SmartInstaller or at least changing the process because I got a notification through Ovi Publisher that you will no longer require the statement that says the application may require up to 13MB of additional downloads (Qt Installer).

Don't know if this solution is legal (GPL, LGPL), but it should work.

Take files qcamera.cpp and qcamera.h from the qtmobility 1.1 for symbian source and include them into your project.

From what I've understood I must use Symbian c++ in Qt, but now the prblem is that I'm not able to do, what I'd like to know is:

1- how to start standard nokia camera
2- how can i catch photo

Thanks for your support.

Refer "this":http://wiki.forum.nokia.com/index.php/Camera_Application_Engine_API link for achieving the above in symbian.

But the link that you've posted talk about S60, can i use it even if I'm developping to symbian^3?

xsacha

There shouldn't be a difference. Try it out on a S^3 device.

As mentioned above - it should most probably work with Symbian^3 if the plugin is available.

Yes and better develop the complete app in Symbian than Qt as you need to put it on Ovi. You will have to develop the engine in native Symbian and if you develop the ui part also in Symbian instead of Qt - probably your app will support wider range of devices.

But then again you Qt mobility is mainly for mobile devices and these API's won't be supported on Desktop right. And N900 being the only maemo device with Qt updates the target audience is very few. Maybe once meego comes in the scenario might change.

Read the first post from here: https://developer.qt.nokia.com/forums/viewthread/1732/
It says "but also provide useful application functionality across desktop platforms."

xsacha

It's quite useful and a time saver. I don't see the problem. SmartInstaller will install the latest on the users system.

xsacha

It wouldn't update your app if you didn't use SI either. What's the point?

If you mean your app will be built on an older Qt, that's fine. Qt will be backwards compatible with your app anyway. You can update it in your own time.

xsacha

Well Qt Mobility obviously has a very useful API set and is very quick to code with. Better to use the wheel than reinvent it. And it does link in well with Qt. SmartInstaller means that you don't need to worry about whether the user has it on their system or not. So, it's win/win.
What would you use instead?

The only problem (with regards to topic) is that the QtMobility the user wants isn't allowed to be deployed in Ovi, yet.

xsacha

No, we've been over this. Write once, it will always work. You don't need to update your code because new Qt versions come out.

xsacha

Oh I guess Nokia weren't talking about QtMobility. I got it confused when Nokia mentioned that all Qt4.6.3 apps will work in future.

Well just keep updating your apps if they ever break ;) I'm sure Nokia won't break it intentionally.

But these days decisions made by Nokia confuses developers a lot. You cannot say if they will stick to one plan. Especially, the way the roadmap is being changed.

xsacha

I will still use it especially for camera, regardless. I prefer coding a little a lot rather than a lot a little.

xsacha

You don't get Qt apps signed. Nokia signs it for you. It's completely free. (Exception being when it requires too much capability).

I submit unsigned app on Ovi Publish, mark it as 'unsigned' and Nokia does the rest. Hopefully this is what you meant.

Only if they break compatibility. If they didn't, it would be a no-brainer. Code a little, little.
