The Common Media Application Format (CMAF) is a standard for the encoding and packaging of segmented media objects for adaptive streaming. CMAF unifies MPEG DASH and HLS in a way that allows the authoring of an MPEG DASH manifest and an HLS playlist that point to shared media segments, thus having just one set of encoded segment files.
mp4dash tool supports creating such HLS + DASH presentations, using the
--hls command-line option. See the MPEG DASH page for details
