As per ISO/IEC 14496 Part 12 : ISOBMFF , the track Identifier specified in track header box "trak" and track fragment header "tfhd" box should be same and unique to each track available in an ISO file.
Also as per ISO/IEC 23009 Part 1 , The track Identifier is same for all the representation of same content component type and unique to a media content component type( Audio / Video etc . . .) in an adaptation set.
But , Most of the mpeg dash non multiplexed sample streams available in internet has used same track Identifier in all of the media tracks ( Audio , video etc. . . ) available for a media presentation. Say track ID for all content component type is 1.
In this case, If a media player is supported with single mp4 demuxer means, it is not possible to demux the fragmented media sample from various track correctly for a media presentation.
My question is,
Having same track identifier for all media content component type in a dash media presentation is MPEG DASH Standard ?
