Advanced Fast Start and buffering disabled for live events Stas 4/24/2007 7:14:00 PM Hi. I'm experimenting with my publish points to find the optimal settings for live events. I noticed the Advanced Fast Start is disabled by default, and buffering is enabled. Any idea if reversing them (enabling AFS and disabling buffering) will improve the end-user experience? Thanks, Stas.

I wouldn't much about with that too much. AFS will be ineffective unless you're archiving to disk, and have enabled play while archiving, because your live event obviously has no way to prestuff the buffer if the client joins at the start. Similarly, buffering is enabled as pretty much an essential part of the media streaming experience - only disable it if you *must* kill a small portion of latency (i.e. if it's vitally important your users see the least possible lag). Disabling this will affect the stability of the stream experience at the client end, especially for users on marginal net connections.

Re: Advanced Fast Start and buffering disabled for live events Stas 4/25/2007 8:32:05 AM Hi. Thanks for the information, it clarifies the things a bit. About the AFS, if there is no archiving, will it be still helpful to clients joining after the live event has began (rather then on it's start)? Thanks, Stas.
