They will anyway be ignored and amount to more or less the no-interop situation we're in if we continue on the current path and have no consensus. No consensus means the various players doing as they prefer, which is what they'd do if there is a SHOULD. I don't agree. I think that MUST implement at least one of them, and SHOULD do both, provides both clear guidance as to the interop points, and clear pressure to implement both. I think it's as close to interop as we are likely to get. I have no idea why browsers should be singled out for special pain, nor whether that is remotely reasonable, nor whether there is a good definition of one (look at the places where projects such as webkit are embedded, for example). > > > On Thu, Nov 14, 2013 at 6:37 AM, Jeremy Fuller <jeremy.fuller@genband.com> wrote: > Hi, > > Gaining IETF consensus on making it mandatory to support only H.264 or only VP8 has clearly failed. I would welcome anyone to share their thoughts on why they believe this situation will change anytime in the next few years. Therefore, can I suggest that we remove items 1 and 2 from the list. Hopefully this will speed up the process by focusing efforts towards gaining agreement on one of the remaining options. > > The following alternatives has been proposed: > • All entities MUST support H.264 > • All entities MUST support VP8 > • All entities MUST support both H.264 and VP8 > • Browsers MUST support both H.264 and VP8, other entities MUST support at least one of H.264 and VP8 > • All entities MUST support at least one of H.264 and VP8 > • All entities MUST support H.261 > • There is no MTI video codec > • All entities MUST support H.261 and all entities MUST support at least one of H.264 and VP8 > Regards, > Jeremy Fuller > > > _______________________________________________ > rtcweb mailing list > rtcweb@ietf.org > https://www.ietf.org/mailman/listinfo/rtcweb > > > > > -- > Jonathan Rosenberg, Ph.D. > jdrosen@jdrosen.net > http://www.jdrosen.net > _______________________________________________ > rtcweb mailing list > rtcweb@ietf.org > https://www.ietf.org/mailman/listinfo/rtcweb David Singer Multimedia and Software Standards, Apple Inc.
