QML CameraRecorder Crashing QT5.10

andyDT

Hi Guys,

I wondered if you can help. I am using the Camera Recorder on my Rpi Project (Stretch Image). The camera works fine. however when I try and record I the application crashes. I get this error info:

AL lib: (EE) ALCcaptureAlsa_open: Could not open capture device 'default': No such file or directory
CameraBin warning: "not negotiated"
CameraBin error: "Could not open device."
CameraBin error: "Internal data stream error."

This is my implementation in QML:

    Camera {
        id: csi2Device;
        objectName: "csi2Device";
        deviceId: QtMultimedia.availableCameras[0] ? QtMultimedia.availableCameras[0].deviceId : 0;
        captureMode: Camera.CaptureVideo;
        videoRecorder {
             resolution: "640x480";
             frameRate: 30;
             videoCodec: "h264";
             mediaContainer: "mp4"
             outputLocation: "test.mp4";
             onRecorderStateChanged: {
                if (csi2Device.videoRecorder.recorderState == CameraRecorder.StartingStatus) {
                    DataModel.IsRecording = true;
                    console.log("saved to: " + csi2Device.videoRecorder.outputLocation)
                }
                else {
                    DataModel.IsRecording = false;
                }
             }
        }
    }

    VideoOutput {
        id: viewfinder;
        x: 0;
        y: 0;
        width: parent.width;
        height: parent.height;
        source: csi2Device;
        fillMode: VideoOutput.Stretch
        autoOrientation: true;
        …
}

Any help most appreciated.
