It depends on how you are defining the media calls in the VIPP file. FFCore can convert VIPP to PDF/vt. If the media calls in the VIPP file are retained within the PDF/vt metadata in a manner that matches the spec in the Press SDK then you would not need the VIPP license in FFPS.
However, there are multiple ways to specify media calls in VIPP and this would only cover the case in which VIPP is built to transfer the media constructs to PDF/vt metadata. This is a question that someone from XMPie would have to answer.
