Invalid pointer WinRT-Information: deviceId is a required parameter #3

Closed dgmann closed 6 years ago

dgmann commented 7 years ago

When I run an application using Ortclib on a device which does not have a webcam connected, the application crashes during Ice connection with the following exception:

Microsoft C++ exception: Platform::NullReferenceException ^ at memory location 0x0821F880. HRESULT:0x80004003 Invalid pointer WinRT-Information: deviceId is a required parameter.

If I connect a webcam, everything works just fine. I use the latest version (1.0.54.1) of the ORTC Library from nuget

I have the same exception with WebRTC 1.54.2, in WebRTC.Initialize(this.Dispatcher);.

Unhandled exception at 0x749608F2 in VideoConference1.exe: Microsoft C++ exception: Platform::NullReferenceException ^ at memory location 0x0D92F41C. HRESULT:0x80004003 Ungültiger Zeiger WinRT information: deviceId is a required parameter.

Thank you for the solution. It works, when webcam works.
