</div></div>As i've said in other messages, this example doesn't match this case<br>
at all, since the patent license was not given to us by the same<br>
people who gave us the library, *and* our patent license doesn't even<br>
say anything about the library used to do encoding/decoding. I.E. Our<br>
patent license has 0 to say about our distribution of ffmpeg, only<br>
something to say about our distribution of Chrome, which is only<br>
covered by section 6 of the LGPL 2.1 (which allows distribution under<br>
whatever terms we choose so long as we meet certain requirements,<br>
which we do).<br>

</div>That our patent license does not restrict/grant/say anything about<br>
ffmpeg, only Google Chrome, and Google Chrome itself doesn't fall<br>
under the LGPL 2.1 except through section 6.<br>
