The device may addition- ally be configured to detect one or more segment type (STYP) values in the bitstream, DETECT FTYP VALUE OF CMAF TRACK FILE tive one of the CMAF fragments, and process each of the CMAF fragments starting determine that each of the one or more STYP values corresponds to a start of a respec- f - 424 from the corresponding STYP value. DETERMINE CMAF HEADER STARTS WITH FTYP VALUE j - 426 DETECT STYP VALUES FOLLOWING CMAF HEADER j - 428 PROCESS CMAF FRAGMENTS STARTING AT RESPECTIVE STYP VALUES FIG. 13 I - 420 PARSE BITSTREAM INCLUDING CMAF TRACK FILE j - 422
