Live streams force the demuxer to keep reloading the Manifest from time to time, as the new fragments are being added as they are recorded. The demuxer should also try to keep up and detect when it had to skip fragments, marking the discont flag when that happens. Curiously, the spec doesn't seem to mention when/how a live stream is supposed to end, so keep trying downloads until the demuxer errors out.
