camera engine does not open the back camera cover on my N8 belle

[Tao.Huang]

I have tried the Qt mobility camera api but the performance is bloody bad , so i am trying to use symbian native camera api . The problem is, the front cam is good but the back camera cover never open, pls tell me how is that happen?

thanks everyone

what do you mean by but the back camera cover never open ? and what API are youn using there ?

[Tao.Huang]

first question : yes, there is a small cover but never open in my app;
second question : i'm using symbian native camera engine, note that , i'm just a Qt developer , and i dont know much about symbian c++

thank u for answer

My N8 does not have any additional cover, nor have I seen it with any other N8. Also any casing covers are usually not having any engines for opening them, but they work by sliding them manually.

For any API or platform, you could check the examples available, they would show pretty well how the API works. Then also you could check API documentation to get more information on the usage.

actually my problem is very simple : i downloaded an app which can use the front and back camera, but when i use the code of the app, front camera is nice but the back camera doesn't work

the api i am using is : CCameraEngine, MCameraEngineObserver

thank u so much

So then you should debug and see what goes wrong inside the code when utilizing the back camera.

Do you happen to use some other graphics-intensive API-s in your application (OpenGL, OpenVG, video playback perhaps)? The N8 has a finite amount of video memory, see http://www.developer.nokia.com/Commu...emory_handling for some discussion.
