1. A method for encapsulating media data as a plurality of fragments of one or more media files, each of the fragments comprising a metadata part and a media data part, metadata of the metadata part describing encapsulation of the media data in the media data part, the method being carried out by a server and comprising:
obtaining second media data to be encapsulated within a second fragment,
obtaining second metadata describing encapsulation of the second media data,
determining that some of the second metadata describing encapsulation of the second media data are identical to some of first metadata belonging to a first fragment and describing encapsulation of first media data within the first fragment, and
if some of the second metadata describing encapsulation of the second media data are identical to some of the first metadata describing encapsulation of the first media data and if the second fragment is not to be parsed independently, encapsulating the second media data and a portion of the second metadata within the second fragment, the second fragment further comprising an indication to signal that the metadata part of the second fragment comprises only a portion of the metadata required to parse the media data of the second fragment.
