    Hi,

    I try to capture video using camera on Hololens. 

    Development platform: VS2015, HoloLens, UWP project, release, x86.

    Enable webcamera and microphone in capability setting in the manifest file.

    I got following exceptions:

    Exception thrown at 0x777F6302 (KernelBase.dll) in HolographicApp1.exe: 0x40080201: WinRT originate error (parameters: 0x80040154, 0x00000016, 0x0120E860).
    Exception thrown at 0x777F6302 in HolographicApp1.exe: Microsoft C++ exception: Platform::ClassNotRegisteredException ^ at memory location 0x0120ECF0. HRESULT:0x80040154 Class not registered
    WinRT information: Class not registered

    The exception occurs when I debug to

    MediaFrameSourceGroup::FindAllAsync();

    Any advice are very appreciated!
