Can you point to the exact wording of the gratis patent licensing?

We do not care. FFmpeg already implements dozens of patents, knowingly and
unknowingly, but FFmpeg, as most Free software, is not a finished product,
it falls in the "experimental" category, and as such is not directly touched
by patents: only those building a finished product on top of FFmpeg and
using the corresponding part of the code have to worry about patents.
