 @item segment_list_size @var{size}

 Overwrite the listfile once it reaches @var{size} entries. If 0

 the listfile is never overwritten. Default value is 5.

+@item segment_list type @var{type}

+Specify the format for the segment list file.

+

+The following values are recognized:

+@table @option

+@item flat

+Generate a flat list for the created segments, one segment per line.

+

+@item ext

+Generate a list for the created segments, one segment per line,

+each line matching the format:

+@example

+@var{segment_filename},@var{segment_start_time},@var{segment_end_time}

+@end example

+

+@var{segment_filename} is the name of the output file generated by the

+muxer according to the provided pattern, and should not contain the

+"," character for simplifying parsing operations.

+

+@var{segment_start_time} and @var{segment_end_time} specify

+the segment start and end time expressed in seconds.

+@end table

+

+Default value is "flat".

 @item segment_wrap @var{limit}

 Wrap around segment index once it reaches @var{limit}.
