Android QCamera似乎坏了

为了使用我的手机摄像头（在Nexus 5上），我使用以下代码：

camera = new QCamera;
camera->setViewfinder(ui->viewFinder);
ui->viewFinder->show();

ui->stackedWidget->setGeometry(0,0, 1000, 1700);
ui->viewFinder->setGeometry(0, 0, 1000, 1700);

camera->start(); // to start the viewfinder
qDebug() << camera->error() << camera->errorString();
qDebug() << camera->state() << camera->status();

这有点奇怪，因为如果

start（）

函数失败，它会抛出一个错误：

void QCamera:：start（）[slot]启动相机

如果相机启动，状态将更改为QCamera:：ActiveState 成功，否则会发出错误（）信号

当摄影机状态更改为QCamera:：ActiveState时，启动 摄像头服务可以与报告的实际状态异步 使用QCamera:：status属性

编辑

QList-cameras=QCameraInfo:：availableCameras（）；
foreach（康斯特QCAMERINFO和cameraInfo，摄像机）{
qDebug（）我想你问题的答案就在这里


基本上，它不起作用

我可以确认，在QT的5.3分支下，摄像机从未进入模式8。
5.2.1允许拍摄图像，但取景器不工作

我不知道发生了什么，也不知道为什么他们会停止支持这段代码

QCamera::NoError ""
QCamera::UnloadedState QCamera::UnloadedStatus

QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
foreach (const QCameraInfo &cameraInfo, cameras) {
qDebug() << cameraInfo.deviceName();
}
