MPEG-DASH and fragmented mp4
My understanding of fragmented mp4 is that it is a single file, but
internally it is structured as fragments. Can someone explain to me how
these fragments can be addressed in the .mpd file for DASH? The .mpd files
that I've seen seem to address various segments with separate urls, but a
fragmented mp4, I imagine, would have to be addressed by byte offsets into
the same url. How does the browser then know what times correspond to what
byte ranges?
