 Use strftime() on @var{filename} to expand the segment filename with localtime.
 The segment number is also available in this mode, but to use it, you need to specify second_level_segment_index
 hls_flag and %%d will be the specifier.

 @file{file-20160215-1455569023.ts}, @file{file-20160215-1455569024.ts}, etc.
 Note: On some systems/environments, the @code{%s} specifier is not available. See
