Since the number of people stating their opinion has been large, I'll just reiterate the opinion I had (and hummed for) in Vancouver: Opus and G.711 should be mandatory to implement for RTCWEB. Since the question of whether there's any value to making the decision now has been raised: The first interoperable products implementing RTCWEB are shipping within a very short timeframe. Those first implementations will shape the market for what's actually used in practice. In order to allow applications requiring high quality sound to be among the first ones developed, those first products need to include a common choice of a high quality codec. Having the RTCWEB WG state as a decision that this codec should be Opus helps in making sure these products ship with Opus. The time to decide is now. Harald [Note - the same logic applies to video codecs, but I've accepted that it's impossible to make a consensus decision at this time on that issue. We'll just live with the consequences of that.] On 08/16/2012 07:15 PM, Cullen Jennings (fluffy) wrote: > At the last meeting we took a hum on selecting Opus and G.711 as the mediatory to implement audio codecs.
