Fails to build unless I add  'return NULL;'  in call_vmaf. Pre-existing 
issue. Open ticket is #6878.

Is it possible to have distinctive error messages? I get the same 
message whether the model is not found or found but not successfully 
parsed. Pasted below. Earlier, the console would have the exception 
reporting if "No newline at end o string". The error for missing file 
was generic, like now.

But no more "This application has requested the Runtime to terminate it 
in an unusual way.". Thanks.
