@item master_m3u8_publish_rate @var{master_m3u8_publish_rate}
Publish master playlist repeatedly every after specified number of segment intervals.
-@item -write_prft @var{write_prft}
+@item write_prft @var{write_prft}
Write Producer Reference Time elements on supported streams. This also enables writing
prft boxes in the underlying muxer. Applicable only when the @var{utc_url} option is enabled.
It's set to auto by default, in which case the muxer will attempt to enable it only in modes
that require it.
-@item -mpd_profile @var{mpd_profile}
+@item mpd_profile @var{mpd_profile}
Set one or more manifest profiles.
-@item -http_opts @var{http_opts}
+@item http_opts @var{http_opts}
A :-separated list of key=value options to pass to the underlying HTTP
protocol. Applicable only for HTTP output.
-@item -target_latency @var{target_latency}
+@item target_latency @var{target_latency}
Set an intended target latency in seconds (fractional value can be set) for serving. Applicable only when @var{streaming} and @var{write_prft} options are enabled.
This is an informative fields clients can use to measure the latency of the service.
+@item min_playback_rate @var{min_playback_rate}
+Set the minimum playback rate indicated as appropriate for the purposes of automatically
+adjusting playback latency and buffer occupancy during normal playback by clients.
+
+@item max_playback_rate @var{max_playback_rate}
+Set the maximum playback rate indicated as appropriate for the purposes of automatically
+adjusting playback latency and buffer occupancy during normal playback by clients.

@item epoch
The start number will be the seconds since epoch (1970-01-01 00:00:00)

The start number will be based on the current date/time as YYYYmmddHHMMSS. e.g. 20161231235759.
@item hls_fmp4_init_filename @var{filename}
Set filename to the fragment files header file, default filename is @file{init.mp4}.
+@item hls_fmp4_init_resend
+Resend init file after m3u8 file refresh every time, default is @var{0}.
+
When @code{var_stream_map} is set with two or more variant streams, the
@var{filename} pattern must contain the string "%v", this string specifies
the position of variant stream index in the generated init file names.
By default, a single hls variant containing all the encoded streams is created.

+the input file has one text subtitle stream at least.

@item cc_stream_map
Map string which specifies different closed captions groups and their
attributes. The closed captions stream groups are separated by space.
If this option is set to a non-zero value, the muxer will reserve a given amount
of space in the file header and then try to write the cues there when the muxing
-finishes. If the available space does not suffice, muxing will fail. A safe size
-for most use cases should be about 50kB per hour of video.
+finishes. If the reserved space does not suffice, no Cues will be written, the
+file will be finalized and writing the trailer will return an error.
+A safe size for most use cases should be about 50kB per hour of video.
Note that cues are only written if the output is seekable and this option will
have no effect if it is not.
+@item default_mode
+This option controls how the FlagDefault of the output tracks will be set.
+It influences which tracks players should play by default. The default mode
+is @samp{infer}.
+@table @samp
+@item infer
+In this mode, for each type of track (audio, video or subtitle), if there is
+a track with disposition default of this type, then the first such track
+(i.e. the one with the lowest index) will be marked as default; if no such
+track exists, the first track of this type will be marked as default instead
+(if existing). This ensures that the default flag is set in a sensible way even
+if the input originated from containers that lack the concept of default tracks.
+@item infer_no_subs
+This mode is the same as infer except that if no subtitle track with
+disposition default exists, no subtitle track will be marked as default.
+@item passthrough
+In this mode the FlagDefault is set if and only if the AV_DISPOSITION_DEFAULT
+flag is set in the disposition of the corresponding stream.

@item mpegts_m2ts_mode @var{boolean}
Enable m2ts mode if set to @code{1}. Default value is @code{-1} which
