An example is shown below for an H.264 video track with 2 spatial qualities at 360p and 720p, however, the framerate between tracks vary dyadically.
Video Track 1 codec: "avc3.42E01E" bitrate: 500000 framerate: 30 width: 640 height: 360 Video Track 2 codec: "svc1.56E01F" bitrate: 1000000 framerate: 60 width: 1280 height: 720
When ready for publishing, the mapping to the MOQT object model and to underlying QUIC, follows the same procedures as described in Section 4.2 for each video track.
When decoding at the 'End Consumer' for a given MOQT group, the objects from across the tracks must be fed in the timestamp order to the decoder, if no frame reordering is present in the encoding.
If the encoding uses frame reordering, or if timestamp cannot be obtained, the object to choose next shall follow the below formula.
Object Decode Order = ObjectID * multiplier + offset multiplier = 2^(maxlayer-max(0,layer-1)) offset = 2^(maxlayer-layer) MOD multiplier
