That could have been avoided if multicast had been a part of the distribution technology. But I can understand why it wasn't. I would point at that time delay being more related to various aspects of my bête noir, bufferbloat, cropping up, be it in the transport itself, or in the application. RTMP implementations, in particular, are notoriously laggy. There are multiple other problems possibly in that time delay related to encode, decode time. Also, for all we know, some of that lag was for a censor on the stream. Actually investigating where those 15 seconds went would be interesting - who to ask?
