Could there be a better place to invoke this IMFMGASADMConstraintsChecker.checkMGASADMVirtualTrackParameterSet() method? Maybe in the inheritors of the ApplicationComposition class?

Since this is a factory class that doesn't invoke any other constraints checks, there may be a better, more targeted place to perform these validations.
