No, this is not supported for now.

Translate your error code to error messages. If it is Linux, then -12 is ENOMEM, which seems to indicate a different kind of problem.

It is for when you create the filter graph, if you want to create it programatically rather than writing a graph description. Regards, -- Nicolas George
