Re: [rtcweb] Straw Poll on Video Codec Alternatives

[Mohammed Raad <[e-mail]>]

David,

Is it your understanding that Nokia is unwilling to license the patents
they have listed in the declaration that you refer to and so you repeatedly
say that VP8 has unlicensable IPR?

My understanding is that they are not willing to license under the options
provided on the form, not that they are unwilling to license.
