Native Development

I've looked at the camera native sample app and I am adjusting it, just having a newbie play really.

I'm trying to get the flash to always be on but am not having any luck, any ideas?

hasFlash is a bool.

 camera_error_t err;
    // open the specified camera
    err = camera_open(unit,
                      CAMERA_MODE_RW | CAMERA_MODE_ROLL,
                      &handle);
    if (err != CAMERA_EOK) {
        fprintf(stderr, "camera_open() failed: %d\n", err);
        return err;
    }

    hasFlash = camera_can_feature(handle, CAMERA_FEATURE_FLASH);

    if(hasFlash){

	   camera_config_flash(handle,CAMERA_FLASH_ON);
    }

Hi JeffLemon,

take a look at the HelloVideoCamera Sample App, available under https://github.com/blackberry/Cascades-Community-Samples/tree/master/HelloVideoCamera

Try to add

camera_config_videolight(mCameraHandle, CAMERA_VIDEOLIGHT_ON);

into void HelloVideoCameraApp:nStartRear(), such as:

void HelloVideoCameraApp::onStartRear()
{
    qDebug() << "onStartRear";
    if (mViewfinderWindow) {
        if (createViewfinder(CAMERA_UNIT_REAR,
                             mViewfinderWindow->windowGroup().toStdString().c_str(),
                             mViewfinderWindow->windowId().toStdString().c_str()) == EOK) {
            qDebug() << "created viewfinder";
            camera_config_videolight(mCameraHandle, CAMERA_VIDEOLIGHT_ON);
        }
    }
}

 Hope this helps.

Are you trying to turn the LED on?  Or do you want the flash to fire each time you take a picture?

If all you want is the LED with no camera, then you should be able to:

camera_open(....);
camera_config_videolight(handle, CAMERA_VIDEOLIGHT_ON);

If you are actully trying to force the flash to fire on each photo you take, then you would use camera_config_flash().  I have sample code coming for this....

Cheers,
