视频拍摄:

 

TInt CCameraEngine::StartVideoCaptureL()
    {
    if (iCamera->VideoCaptureActive())
        {
        return KErrInUse;
        }
    else
        { 
        iCamera->PrepareVideoCaptureL(CCamera::EFormatYUV420Planar,iVideoSizeIndex,0,1,1);
        iCamera->StartVideoCapture();
        return KErrNone;
        }
    }

void CCameraEngine::FrameBufferReady(MFrameBuffer* aCameraBuffer,TInt aError)
    {
    if(aError==KErrNone)
        {
        TDesC8* ptr=aCameraBuffer->DataL(0);
        if(ptr)
            {
            iObserver.OnFrameBufferReady(*ptr);
            }
        aCameraBuffer->Release();
        }
