I now understand that your statement was only that Google's
distribution of FFMPEG is not in violation of the LGPL due to patent
licenses. Thank you for clarifying what you have stated. I will ask no
further questions on that point.


But I do have one further question:

Can you please tell me if, when I receive Chrome from you, I also
receive the patent licensing sufficient to use the Chrome package to
practice the patents listed in MPEG-LA's 'essential' patent list for
the decoding of H.264?  I wouldn't want to break any laws.

I believe I know the answer, based on your statement "No more or less
? than ? ffmpeg" as ffmpeg explicitly does not provide any patent
licensing, but it seems surprising so I am asking for clarification. A
simple yes or no will suffice.

Thank you!
