Did you create this plugin?  In Visual Studio, make sure it is referencing the same version of Autofac as some other plugin.

RE: "... this is the audio video plugin available."

Please explain that.  Is it a 3rd party plugin (created by some other developer)?  If so, you should contact them for support
