Mo,

I think we all agree that choosing H.264 or VP8 would be better, but it is
clear that neither option today has consensus.    Circumstances could change
in the future, but it seems that OpenH264 was not enough to change that
circumstance.

I think that where your scenario might go astray is that users won¹t
associate their poor experience with ³WebRTC², or ³that web stuff² ‹ they
will associate it with the brand of the service which they are using at the
time.

So, for example, if Facebook builds video chat using WebRTC, and they do no
transcoding, 30% of users might associate their poor video with Facebook,
but most of them won¹t call it ³that web shit² ‹ they would say Facebook
video sucks.

Of course, Facebook could decide to transcode 30% of the time, in which case
the user would have a different experience.

Facebook obviously just being used as an example service which might
implement WebRTC video.
