the SEI messages describe respective ones of the sequence of coded video pictures and include elements common to more than
one of the coded video pictures;

encapsulating the SEI messages in an initialization segment, wherein the initialization segment comprises a first file of
a plurality of files of a media representation, wherein encapsulating the SEI messages in the initialization segment comprises
encapsulating the SEI messages in the first file, wherein the initialization segment is associated with a uniform resource
locator (URL), and wherein the first file and the initialization segment do not include any media data;

encapsulating the sequence of coded video pictures in one or more video files of the plurality of files separate from the
first file, wherein URLs for the one or more video files are distinct from the URL with which the initialization segment is
associated; and

outputting the first file prior to outputting any of the one or more separate video files.
