Multiple MPD


We’ve set up a standard SMIL for adaptive bitrate live stream using DASH on our streaming server. I’ve noticed in the network tab that I’m seeing multiple MPD files getting pulled off the server. This seems odd to me as I’ve never seen more then one .mpd file come through when I stream using dash (I’ve tested a process on the DASH site: From what I can tell these files are not coming from cache. Is this specific to live streaming?

That said, why is this happening and can we turn this off if it’s not needed?

Please advice as to what is going on?

If you are streaming live, chunklist in MPD manifest (same for HLS) is not final and it should must be populated as video goes in time.
For VOD you would usually download manifest once.
