Abstract
A method of encapsulating media data into a media file, the method comprising: obtaining a time boundary in a time interval corresponding to the presentation duration of an original sample of the media data; duplicating the original sample into two consecutive duplicated samples separated by the time boundary, the two duplicated samples having a same data part corresponding to the data part of the original sample; generating a time adjustment indication indicating for each duplicated sample the relationship between the time interval corresponding to the presentation duration of the duplicated sample and the time interval corresponding to the presentation duration of the original sample; and encapsulating the media data comprising the duplicated samples and the time adjustment indication in the media file, the time adjustment indication being located in metadata describing the media data.
