  /*3.3.2.  EXTINF

   The EXTINF tag specifies the duration of a media segment.  It applies
   only to the media segment that follows it, and MUST be followed by a
   media segment URI.  Each media segment MUST be preceded by an EXTINF
   tag.  Its format is:

   #EXTINF:<duration>,<title>

   where duration is an decimal-integer or decimal-floating-point number
   that specifies the duration of the media segment in seconds.
   Durations that are reported as integers SHOULD be rounded to the
   nearest integer.  Durations MUST be integers if the protocol version
   of the Playlist file is less than 3.  Durations SHOULD be floating-
   point if the version is equal to or greater than 3.  The remainder of
   the line following the comma is an optional human-readable
   informative title of the media segment.

   The EXTINF duration of each media segment in the Playlist
   file, when rounded to the nearest integer, MUST be less than or equal
   to the target duration.
