Dear All
I am facing a camera problem when using QT5 GUI libraries, pls see my implementation
int Q_DECL_EXPORT txHalInit()
{ if(!camera) { camera = new QCamera(QCameraInfo::defaultCamera());
if(!camera) return -1;
cameraViewfinder = new QCameraViewfinder();
if(!cameraViewfinder) { delete camera; return -1;
}
int Q_DECL_EXPORT txToggleVideo(void)
{ if(camera) { if(isVideoOn == false)
{ if(camera->state() == QCamera::UnloadedState) { cameraViewfinder->show();
camera->setViewfinder(cameraViewfinder);
camera->start();
}
cameraViewfinder->setWindowOpacity(1.0);
isVideoOn = true; return 1;
}
else
{ cameraViewfinder->hide();
//cameraViewfinder->setWindowOpacity(0.0);
camera->stop();camera->unlock(); camera->unload();
isVideoOn = false; return 0;
}
}
return -1;
}
}
When I try to toggle camera video on and off twice, i get below error, The camera will stop capture video when getting below error
void CameraBinSession::setState(QCamera::State) QCamera::ActiveState
GstElement* CameraBinSession::buildCameraSource()
bool CameraBinSession::setupCameraBin() Viewfinder changed, reconfigure.
