This muxer supports the following options:

-@item hls_init_time @var{seconds}
-Set the initial target segment length in seconds. Default value is @var{0}.
+@item hls_init_time @var{duration}
+Set the initial target segment length. Default value is @var{0}.

Segment will be cut on the next key frame after this time has passed on the
first m3u8 list.
After the initial playlist is filled @command{ffmpeg} will cut segments
at duration equal to @code{hls_time}
