SensorStreamViewer, HoloLensForCV : "Failed to initialized media capture: Access is denied." - augmented-reality

Question

I tried to get sensor stream from HoloLens, so I used the HoloLensForCV.
(https://github.com/Microsoft/HoloLensForCV)
First, I checked that SensorStreamViewer project works, but few days later, I updated HoloLens and then it doesn't work. The error I receive is Access is Denied
HoloLens Camera view capture
HoloLens Privacy Camera capture
The Webcam capability in VS capture
And, I guess the error occurs in this part(SensorStreamViewer.xaml.cpp).
// Initialize MediaCapture with the specified group.
// This must occur on the UI thread because some device families
// (such as Xbox) will prompt the user to grant consent for the
// app to access cameras.
// This can raise an exception if the source no longer exists,
// or if the source could not be initialized.
return create_task(m_mediaCapture->InitializeAsync(settings))
.then([this](task<void> initializeMediaCaptureTask)
{
try
{
// Get the result of the initialization. This call will throw if initialization failed
// This pattern is docuemnted at https://msdn.microsoft.com/en-us/library/dd997692.aspx
initializeMediaCaptureTask.get();
m_logger->Log("MediaCapture is successfully initialized in shared mode.");
return true;
}
catch (Exception^ exception)
{
m_logger->Log("Failed to initialize media capture: " + exception->Message);
return false;
}
});
When I start others project like 'ComputeOnDevice', I can see an alert message window asking me allow to access camera. However, when I start 'SensorStreamViewer', I didn't see any alert message asking about camera access.
I started debugging, and confronted this error message.
Exception thrown at 0x772C3332 in SensorStreamViewer.exe: Microsoft C++ exception: Platform::AccessDeniedException ^ at memory location 0x0180E680. HRESULT:0x80070005 Access is denied.
WinRT information: The required device capability has not been declared in the manifest.
How can I solve this problem?

In your Package.appxmanifest file, you need to add the following capability.
<rescap:Capability Name="perceptionSensorsExperimental" />
