FFmpegInteropX crashes on WinUI3

[zjarri]

Hello everyone, I'm trying to get the provided WinUI3 sample to run but it keeps throwing an exception on " Config = new MediaSourceConfig();".

  __System.TypeInitializationException: 'The type initializer for 'WinRT.ActivationFactory`1' threw an exception.'_
  __COMException: Klasse nicht registriert (0x80040154 (REGDB_E_CLASSNOTREG))___ (Class not registered)

The Project uses:

• .NET 7.0
• WindowsAppSDK 1.2
• Community.Toolkit.Mvvm
• Microsoft.Windows.CsWinRT
• FFmpegInteropX 1.1.0-pre3 (since the stable release is not compatible)
• FFmpegInteropX.FFmpegUWP 5.1.100

Im lost in this error message, since im quite new to development. I hope this is the right channel for my question, if not then excuse me.

Install https://www.nuget.org/packages/Microsoft.VCRTForwarders.140

You must run the "MediaPlayerWinUI (Package)" project, not "MediaPlayerWinUI". Unpackaged apps have additional requirements.

Our sample doesn't use mvvm community stuff though.
