A Problem about QtCamera with Qt5.3.2

  • I want to build a Qt Camera application on my ARM device by qml.

    Now My Qt version is Qt5.3.2

    To porting on my arm device ,I had changed gstreamer source(imx*) and sink(imx*) in qtmultimedia\src\plugins\gstreamer\camerabin

    It seed to work, but it only contains one frame (fixed image)

    qml source:

    import QtQuick 2.0

    import QtMultimedia 5.0

          Rectangle {
                width: 640
                height: 480
                Camera {
                        id: camera
                       // imageProcessing.whiteBalanceMode: CameraImageProcessing.WhiteBalanceFlash
                        //exposure {
                              //  exposureCompensation: -1.0
                                //exposureMode: Camera.ExposurePortrait
                       // }
                    //flash.mode: Camera.FlashRedEyeReduction
        VideoOutput {
            source: camera
            anchors.fill: parent
            focus : visible // to receive focus and capture key events when visible


    I get the following warning and error

    CameraBin error: "Internal data flow error."

    Did you first check that your camera is working correctly with gstreamer ?
