stm32mp157 linux Qt QCamera摄像头出现CameraBin error: "Device '/dev/video0' failed during initialization"

在linux上运行qt程序，，摄像头只出现一帧画面之后就不显示了并弹出CameraBin error: "Device '/dev/video0' failed during initialization"错误警告


代码如下：
Widget::Widget(QWidget *parent)    : QWidget(parent){    this->resize(1024,600);
    QCamera *camera = new QCamera("/dev/video0",this);    QCameraViewfinder *vfinder = new QCameraViewfinder(this);    QMediaRecorder *recorder = new QMediaRecorder(camera,this);    QVideoEncoderSettings settings = recorder->videoSettings();    settings.setResolution(640,480);    settings.setQuality(QMultimedia::VeryHighQuality);    settings.setFrameRate(30.0);    recorder->setVideoSettings(settings);    camera->setCaptureMode(QCamera::CaptureStillImage);    vfinder->setGeometry(10,10,640,480);    vfinder->move(20,20);    camera->setViewfinder(vfinder);    camera->start();}
