I'm trying to identify if a QCamera has a flash. Ideally, I'd like this done
in QML, but there seems to be no support for it yet. So I'm making a QML type
in C++.
So in C++:
qDebug() << "Default:" << QCameraInfo::defaultCamera().deviceName() <<
QCameraInfo::defaultCamera().position();
camera = new QCamera();
if (camera) {
QCameraExposure *exp = camera->exposure();
if (exp) {
qDebug() << "QCamera ok, returning flash modes"
<< exp->isFlashModeSupported(QCameraExposure::FlashOn)
<< exp->isFlashModeSupported(QCameraExposure::FlashAuto)
<<
exp->isFlashModeSupported(QCameraExposure::FlashManual);
return exp->isFlashModeSupported(QCameraExposure::FlashOn);
}
}
Default: "com.apple.avfoundation.avcapturedevice.built-in_video:0"
QCamera::BackFace
However all I ever get is false. This is being run on an iPhone 5S, which does
have a backface flash, and I do use the flash successfully in QML. I'm
attempting to also support iPads which do not have a flash at all, but I need
to know that the flash does not work.
Does anyone know what I might be doing wrong?
