Recording with video camera

Hello

I don't know if maybe the camera Documentation is not aligned with the API documentation. I was wondering if someone could guide me toward the Dev Alpha camera to record. The following code gets the camera started correctly.

// Initialize Video Cam
    QmlDocument *qml = QmlDocument::create("asset:///videoCam.qml");
    mVideoCam = qml->createRootObject();
    Camera *camera = mVideoCam->findChild("myCamera");
    camera->open(CameraUnit::Front);

And then I push the camera into the view with:

mNavPane->push(mVideoCam);

The camera is running. What is not clear to me, I get the following error when I "startVideoCapture()":

Dec 16 22:22:17.933 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default    301  CamControllerInternal::StartVideoRecording Error -> Invalid vf mode. (vf mode:1)

Dec 16 22:22:17.933 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default    301  CamControllerInternal::ExecuteCommand STARTVIDEORECORDING = result (15)

Dec 16 22:22:17.933 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default    300  void bb::cascades::multimedia::CameraPrivate::onRecordingFailed(CamResult) called.
Dec 16 22:22:17.933 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default   9000  OrientationSupportPrivate::setSupportedDisplayOrientation: displayOrientation: All
Dec 16 22:22:17.933 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default   9000  OrientationSupportPrivate::setSupportedDisplayOrientation: successfully changed to All
Dec 16 22:22:17.934 com.example.DiveBook.testDev_le_DiveBook7e1553ee.15999178              default   9000  onVideoCaptureFailed signal received with error 3

I guess that means Mode VF 'invalid', I have to set something correctly bound to my viewfinder? Can someone show me and example?

Here is my videoCam.qml for reference:

// Default empty project template
import bb.cascades 1.0
import bb.cascades.multimedia 1.0

Page {
    // This is the camera control that is defined in the cascades multimedia library.
    Camera {
        id: camera
        objectName: "myCamera"

        onTouch: {
            if (event.isDown() && !camera.videoCaptureStarted()) {
                // Take photo
                startVideoCapture();
            }
        }

        // When the camera is opened we want to start the viewfinder
        onCameraOpened: {
            camera.startViewfinder();
        }

        // There are loads of messages we could listen to here.
        // onPhotoSaved and onShutterFired are taken care of in the C++ code.
        onCameraOpenFailed: {
            console.log("onCameraOpenFailed signal received with error " + error);
        }
        onViewfinderStartFailed: {
            console.log("viewfinderStartFailed signal received with error " + error);
        }
        onViewfinderStopFailed: {
            console.log("viewfinderStopFailed signal received with error " + error);
        }
        onVideoCaptureFailed: {
            console.log("onVideoCaptureFailed signal received with error " + error);
        }
    }
}

Thank you

I think I solved it. I had to fill an instance of the CameraSettings class, and then apply it to my camera photo using "camera.applySettings ()".

  • How to capture (record) streaming video online with his partner is on El Capitan?

    Someone can advise or recommend including many different programs available that I must use to capture (record) streaming video online with it's associated audio on El Capitan?  I tried MacX DVD Converter Pro, but believe it or not, it does not record the audio aspect of video stream.  They claim there is a work around, but after 3 days of trying various corrections, none seems to work for me.

    I tried the Safe Mode Terminal command string: turn off the csrutil. restart, but which did not allow audio capture of MacX DVD Converter Pro driver to install their Audio System driver.

    I tried sudo nvram boot-args = "kext-dev = 1 mode" method, but then again, playback of the recorded video was silent, even though I have heard the audio during recording. "

    I downloaded SOUNDFLOWER, but again, I have heard audio when the screenshot, but Quicktime playback was silent.

    I have hard to believe after that 3 days I am still unable to record what I see and hear at the same time on my screen a video streaming like a Charlie Rose interview with Martin Scorcese discussing Felini.  I don't like what it costs; I care only about the easy, professional and perfect results.  One of the two reasons why I BOUGHT this iMac 27 "with El Capitan was so I COULD record streaming video with audio if I choose so, and after a month, I still can't do and I ran out of the online help after searching dozens of sites to find answers!  So I now turn to the Apple community.  Thank you!

    3. As soon as you hear the startup tone, hold down the SHIFT key.

      You must press the SHIFT key as soon as possible once you hear the startup tone, but not before.

    4. Release the SHIFT key when you see the gray Apple logo and progress indicator.

    To exit safe mode, restart your Mac, but no press during the startup.

    Take care.
