    rtcweb WG in IETF89 回避
  21. MIRACLE!!!

    from Peter Saint-Andre via IETF rtcweb Mailing List [Jan 29] ">If anyone has concerns about tabling this discussion until September >29, 2014 please let us know by February 4. I have concerns that September 2014 is too soon. It was relatively easy for the WG to choose two MTI audio codecs because Opus was a clear winner among modern codecs (and because we had an obvious fallback). We have no such codec in the video space. My suggestion is to wait until we have such a codec (and, in parallel within some other WG or initiative, push hard to make that happen), rather than continue the endless and fruitless wrangling over the current options."

    videocodec BoF (in IETF85 Nov, 2012)  Internet Video Codec BOF  「今度こそRFのInternetのVideo Codecを!」  「「「「「え?」」」」」  "Recent efforts within the MPEG LA to create an RF license for the Restricted Baseline profile of H.264, while ultimately unsuccessful, showed that there are many consumer device manufacturers that would support RF licensing for a video codec." (BoFのDescriptionより)  VPnext! → VP9  HD画質に対応とか色々  Daala etc...
