Re: Camera Backlight problem

Thanks for your reply serg3d
But as far as I know CHWRMLight is used for S60 3rd edition only and not for UIQ3
Does UIQ3 has something else to keep backlight ON

You can use CHWRMLight interface to turn backlight on permanently. Check forum nokia wiki, it has code sample.

Re: CCameraAdvancedSettings: Not implemted on s60rd FP2 1.1?

Michton — Wed, 10 Sep 2008 17:06:23 +0200

We got help from a nokia champion:

We should use CCamera::NewL2 and Observer2.
we tried and failed rto make it work.

There is no example in the world with these function.

They said that the implemtation should be soon in forum nokia wiki.

Let's wait.

on Hindsight the above code given only gives you the Model Number of the phone

Check for other functions in CTelephony

Hi Abhrodeep,

You can use CTelephony API to get information about the Phone. Here is the code:

Header File:

#ifndef TELEPHONEMODEL_H_
#define TELEPHONEMODEL_H_
#include "Etel3rdParty.h"
#include "e32base.h"

class MTelephoneModelCallbacks
{
public:
virtual void ModelName(const TDesC& aModel) = 0;
};

class CTelephoneModel:public CActive
{
public:
static CTelephoneModel* NewL(MTelephoneModelCallbacks* aTelephoneCallbacks);
static CTelephoneModel* NewLC(MTelephoneModelCallbacks* aTelephoneCallbacks);
~CTelephoneModel();
private:
MTelephoneModelCallbacks* iCallbacks;
CTelephony* iPhone;
CTelephony::TPhoneIdV1 iResult;
void ConstructL(MTelephoneModelCallbacks* aTelephoneCallbacks);
CTelephoneModel();

private:
void DoCancel();
void RunL();

public:
void GetModelName(); //Call thi function, you will get Model information in a callback function
};

#endif /*TELEPHONEMODEL_H_*/

CPP File:

#include "TelephoneModel.h"

CTelephoneModel* CTelephoneModel::NewL(MTelephoneModelCallbacks* aTelephoneCallbacks)
{
CTelephoneModel* self = CTelephoneModel::NewLC(aTelephoneCallbacks);
CleanupStack::Pop(self);
return self;
}

CTelephoneModel* CTelephoneModel::NewLC(MTelephoneModelCallbacks* aTelephoneCallbacks)
{
CTelephoneModel* self = new (ELeave) CTelephoneModel;
CleanupStack::PushL(self);
self->ConstructL(aTelephoneCallbacks);
return self;
}

CTelephoneModel::CTelephoneModel():CActive(EPriorityStandard)
{
iCallbacks = NULL;
iPhone = NULL;
}

void CTelephoneModel::ConstructL(MTelephoneModelCallbacks* aTelephoneCallbacks)
{
iCallbacks = aTelephoneCallbacks;
iPhone = CTelephony::NewL();
CActiveScheduler::Add(this);
}

void CTelephoneModel::DoCancel()
{

}

CTelephoneModel::~CTelephoneModel()
{
if(iPhone)
{
delete iPhone;
iPhone = NULL;
}
iCallbacks = NULL;
Cancel();
}
void CTelephoneModel::RunL()
{
if(iCallbacks == NULL)
return;
if(iStatus == KErrNone)
iCallbacks->ModelName(iResult.iModel);

}

void CTelephoneModel::GetModelName()
{
CTelephony::TPhoneIdV1Pckg pack(iResult);
iPhone->GetPhoneId(iStatus,pack);
SetActive();
}

Re: StartViewFinderBitmapsL

gmsk19 — Tue, 01 Jul 2008 06:45:48 +0200

The Code that Should Come in PowerOnComplete() is as follows

       if(aError == KErrNone)
        {
                TCameraInfo info;
                iCamera->CameraInfo(info);
                TInt mode = info.iNumImageSizesSupported-1;
                
                CCamera::TFormat format = CCamera::EFormatMonochrome;
                //Check For Support Image Format
                if(info.iImageFormatsSupported && CCamera::EFormatExif)
                {
                        format = CCamera::EFormatExif;
                        iCamera->SetJpegQuality(100);
                }
                else
                {
                        iCameraObserver->CameraError(_L("Camera : Image Format Not Supported"));
                }
                iCamera->PrepareImageCaptureL(format,mode);
                //Check For Flash Support
                if(info.iFlashModesSupported && CCamera::EFlashAuto)
                {
                        iCamera->SetFlashL(CCamera::EFlashAuto);
                }

                TCameraInfo aCameraInfo;
                iCamera->CameraInfo(aCameraInfo);
                TSize aSize;
                TInt cc = aCameraInfo.iNumImageSizesSupported;
                for( TInt i=0; i<cc; i++ )
                {
                        iCamera->EnumerateCaptureSizes(aSize, i, CCamera::EFormatExif);
                        // capture final high-quality (640 x 480) bitmap
                        if(aSize.iWidth == 640)
                        {
                                iCamera->StartViewFinderBitmapsL(aSize);
                                break;
                        }
                }
        }

Re: StartViewFinderBitmapsL

gmsk19 — Tue, 01 Jul 2008 06:41:21 +0200

StartViewFinderBitmapsL() on Success Calls the Function void ViewFinderFrameReady(CFbsBitmap &aFrame);. In this Function you would have to implement you draw code.
The Best way is to make your container Inherit McameraObserver. It has the following methods which are called in succession in that order

//call  iCamera->Reserve in ConstructL()
 void ReserveComplete(TInt aError); //Power On Camera Here

 void PowerOnComplete(TInt aError);  //StartViewFinderBitmapsL comes here

 void ViewFinderFrameReady(CFbsBitmap &aFrame); // Draw Comes here

 void ImageReady(CFbsBitmap *aBitmap, HBufC8 *aData, TInt aError); //Once Clicked Pic data Comes here

 void FrameBufferReady(MFrameBuffer *aFrameBuffer, TInt aError); //Required in Case of Video capture Ignore it

Re: Empty frames at VideoBufferReady

senoctar — Sun, 23 Mar 2008 21:28:50 +0100

Never Mind
I found the problme, the documentation and example program was missleading.
I was using aFrameBuffer->DataL(aCameraBuffer.iIndexOfFirstFrameInBuffer) instead of aFrameBuffer->DataL(0)
