Policy QML camera question

Hello

When you use element QML camera in my application, I was faced with the following problem - Z10 camera he always does photo in landscape orientation, even if the device is in portrait mode. AFAIK, QML camera should deal with orientation of the unit by itself, and it doesn't have even the methods or properties to combat it. All other screen elements (such as the navigation pane) to have proper placement for the current orientation of the device (as for the navigation pane, it is always on the bottom of the screen). The code example looks like this:

import bb.cascades 1.0
import bb.cascades.multimedia 1.0
import bb.multimedia 1.0

Page {
    id:         cameraPage
    objectName: "cameraPage"

    onCreationCompleted: {
        OrientationSupport.supportedDisplayOrientation = SupportedDisplayOrientation.CurrentLocked;
    }

    paneProperties: NavigationPaneProperties {
        backButton: ActionItem {
            onTriggered: {
                navigationPane.pop();
            }
        }
    }

    Container {
        background: Color.Black

        Camera {
            id: camera

            onCreationCompleted: {
                if (allCamerasAccessible) {
                    open(CameraUnit.Rear);
                }
            }

            onCameraOpened: {
                getSettings(cameraSettings);

                cameraSettings.flashMode = CameraFlashMode.Off;
                cameraSettings.focusMode = CameraFocusMode.ContinuousAuto;

                applySettings(cameraSettings);

                startViewfinder();
            }

            onTouch: {
                if (event.touchType === TouchType.Down) {
                    capturePhoto();
                }
            }

            onPhotoCaptured: {
                shutterSound.play();
            }

            attachedObjects: [
                CameraSettings {
                    id: cameraSettings
                },
                SystemSound {
                    id:    shutterSound
                    sound: SystemSound.CameraShutterEvent
                }
            ]
        }
    }
}

I looked for similar problems in the browser of the question and found the following problem:

https://www.BlackBerry.com/jira/browse/BBTEN-249

It is somewhat similar to mine, but it is marked as fixed in Dev Alpha OS 10.0.09, while this problem occurs in 10.1.0.273 on Z10.

What could cause, with the exception of the firmware issue? Should I change something orientation of the camera by hand? How can I do this for element QML camera?

Thanks in advance for your help.

The different flavors of the Z10 (as well as future systems) can manage rotation in different ways. Some will be actually rotate the image for you, some will just tag the jpeg resulting with EXIF data that indicates the orientation of the image desired. Not all image viewers supports EXIF rotation.

In addition, currently on the Z10 rotation of the image is locked for the orientation of the device. So if the user locks the application in portrait mode, all their photos will be marked as if the device is held upright in portrait mode, unless you do a follow-up work with the gyroscope/accelerometer and then rotate the image yourself. You will notice that even in the built in camera app. This is currently a known limit.

Satellite A305-S6905 and Web Cam questions

I apologize if there's another thread for this particular model and the question, I'm just extremely frustrated and after hundreds of searches through google, toshiba and chicony, I can't find a solution. My laptop {Toshiba Satellite A305-S6905} was originally Vista when buying. My uncle put upgraded to Windows 7 and in addition to the fact that he constantly tells me that "this copy of Windows is not genuine", my web cam suddenly stopped working. It worked fine on Vista.

I uninstalled camera Assistance and reinstalled more than 8 times. I * think * I reinstalled the driver, but whenever I open (or try to open) helps the camera, I get the message: "Webcam is disabled or has failed." Please check your webcam settings '. I opened the Device Manager, but the Chicony webcam is not listed. Nothing about the webcam is listed. I restarted my laptop... believe me, I almost tried everything. I noticed that a lot of upgraders from Vista to Windows 7 have the same problem. Last resort, I decided to come on the website of the manufacturer of my laptop. I would appreciate help.

Thank you in advance.

Hello

If there is no entry in the Device Manager, it's quite strange. If the device works properly it is listed under imaging devices like Chicony camera.
Somehow, it seems that there is no link between the cam and the motherboard.

All you can do now is to test the functionality with the settings and see if the problem persists.
If the situation will be the same, you should contact the closest service and leave technician to check the cam feature.

Hi Knight Fan Stan

What is you receive the exact error message?

Method 1 : Clean boot the computer and then try to install the webcam

Follow step 1 in the link below,

http://support.Microsoft.com/kb/929135

If everything works well after a clean boot, you can deduce that some third-party services are at the origin of the problem.

Continue with the remaining steps to pin-point on the third party service.

After find you the program that is causing the problem, you will have to perhaps to update or install a newer version of the program, if you rarely use that you should consider uninstalling the software.

Important: n ' forget not the computer to start normal follow step 7 in the link.

You can try the system restore before it happened.

===========================================

If necessary you may be of the wrong driver for your Version of Windows.

Start - type in the search box-> Winver find upstairs and double click it
He will tell if you have 64-bit.

-----------------------------------------

Double-click Control Panel / Device Manager - Imaging - writing down of the brand and model of camera.
on this subject and on the tab of the driver is version. Now, click on update drivers (who are unable to do anything as MS
is far behind the pilots of certification). RIGHT click on the camera - UNINSTALL - REBOOT - it
will update the driver stack.

Now, go to the system manufacturer's website and download the latest driver for the camera and the other related camera
software (if not more recent get the same).

Just you'd go to Toshiba Support and get the driver for your model laptop.

Go to your model.

Good time to get some other updates here.

Download - SAVE - go to them and RIGHT CLICK - RUN AS ADMIN - reboot after each driver.

Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

If you update the drivers manually, then it's a good idea to disable the facilities of driver in the Windows updates,
This leaves ONE of Windows updates, but it will not install the drivers who are generally older and cause
questions. If updates offers a new driver and then hide it (right click on it) and then go look for new ones
manually if you wish.

"Please restart camera" question...

Get this prompt message while I turn my camera back. Funny thing is the rear camera worked perfectly last week, all of a sudden, it was this like yesterday when I was going to use an application to scan QR to check a QR barcode, when all of a sudden I get this message.

Tried to restart the phone and all the other stuff/guides I've seen on google, but unfortunately, I could not remedy? I'm doing something wrong or is this a hardware problem already? Also, I'm from the Philippines, and I do not know if Motorola has yet to a service center that can help me fix my phone...

If you factory reset and did not add any apps, and the problem persists, then likely material.

Z3C camera question "current in another app record cannot be saved"

Hello!

I got my Z3C and it is a great device but also got a little problem with the camera app whenever I start the original camera application, I also get the following message: "current record in another app could not be saved.
After confirming the dialogue, I can still do the photos and videos. I uninstalled all other applications that might be using the camera and rebooted the device. Nothing helps, the message still appears.

How can any suggestion, I get rid of this message?

You have the same problem. Read that it happens when the 'Google Ok' is enabled

QML layout question

I'm quite new in QML, and I wondered the correct way to achieve this type of layout. I would like to show you a picture as background and want another image on top of this image, so it gives the effect of a contour.

Here's what I think I create a StackLayout layout container and then I have 2 image down one is bigger in size, then the other is smaller.

Thank you for the help

StackLayout is the only provision which could not do what you want without real awkwardness. The part of the "stack" means that they are stacked vertically or horizontally (x or y axis), not from BACK to front (z axis).

For the back layer forward, you can use a container with a DockLayout and make sure that specify the picture then in the list of children of the container. Those who come later is rendered above those that come earlier.

DispositionAbsolue would be another option, but with the same restriction order specifying.

You can also use the 'background' of a container and an ImagePaintDefinition property to set an image as the background, instead of the usual Color.Transparent or a color explicit and then have the image of 'before' simply to be the unique child of this container. In this case, even a StackLayout might work, since there is only one child.

Unfortunately, you are a known problem for which a fix is on the way. In the meantime, you should use the InvokeManager API from C++.

Cisco telepresence camera question - motivates and focus on who speaks. ???

Hi all

Wonder about a telepresence from cisco camera that when placed in a conference room can detect, move and focus on the person speaking?

Is this feature available on the PrecesionHD 4 x camera or another that I do not read this feature in the data sheet?

If so, please provide the reference for this.

Kind regards

It is compatible with the SX80, C40/60/90 points of termination. SpeakerTrack 60 is a unit of two cameras and therefore requires two inputs of camera on the codec, then it will not work with the SX20 because it has only one entrance of the camera. Both cameras help to provide seamless switching of active speakers in the room.

Canon 600 d - should my blurry viewfinder without a purpose is fixed? I have the body of cam

As says the topic, I have a Canon 600 d or Canon eos Rebel t3i and I'm worried because I can't find all the information in the user manual any where on the net about the question to know if I'd see a clear picture in the viewfinder of my camera when no lens is fixed. I had enough $ buy the body of the camera until now and I don't have a goal, and I don't know anyone with a DSLR camera question on this subject. Sorry, this may sound a stupid question - maybe I'm not supposed to be able to clearly see the images in the viewfinder without an AF lenses or another kind have the lens attached to the camera? I just wanted to know for sure if this unit has a serious problem, before I go ahead and buy a goal for her. Thanks in advance to anyone who has the time to clear this for me, if you would like more information about me ill will be happy to give let more just me know what you need. Sorry I'm a super beginner when it comes to high-end cameras

If my viewfinder cameras is not supposed to look that way without objective and this issue is not caused by the glass, then what else could be causing this problem? Maybe I'm getting ahead. I guess I'm just worried, that I have been ripped off when I bought this camera now.

You won't see anything through the viewfinder of any SLR (i.e. the T3i, obviously) without a lens mounted. In fact, you should never take the body Cap out of the unit except to mount a lens. Leaving off the coast is a good way to attract the dust on the mirror or the sensor.
