appears in a Playlist file. Its format is:

decrease.
A Media Playlist file MUST NOT contain more than one EXT-X-MEDIA-
SEQUENCE tag. If the Media Playlist file does not contain an EXT-X-
MEDIA-SEQUENCE tag then the sequence number of the first segment in
the playlist SHALL be considered to be 0. A client MUST NOT assume
that segments with the same sequence number in different Media
Playlists contain matching content.
A media URI is not required to contain its sequence number.
