Please pass an empty string instead of "stdfilters.ftf".

Also make sure, the "pFilter" is not only declared in a local function, because it will be deleted, if the function was left. Make the "pFilter" known in your complete class.

At least, pass only "pFilter" to "setDisplayFrameFilters", not "pFilter.get()".
