+Dynamic Adaptive Streaming over HTTP (DASH) muxer that creates segments

+and manifest files according to the MPEG-DASH standard ISO/IEC 23009-1:2014.

+For more information see:

+ISO DASH Specification: @url{http://standards.iso.org/ittf/PubliclyAvailableStandards/c065274_ISO_IEC_23009-1_2014.zip}

+It creates a MPD manifest file and segment files for each stream.

+

+The segment filename might contain pre-defined identifiers used with SegmentTemplate

+as defined in section 5.3.9.4.4 of the standard. Available identifiers are "$RepresentationID$",

+"$Number$", "$Bandwidth$" and "$Time$".

+

+@example

+avconv -re -i <input> -map 0 -map 0 -c:a libfdk_aac -c:v libx264

+-b:v:0 800k -b:v:1 300k -s:v:1 320x170 -profile:v:1 baseline

+@end example

+

+@table @option

+@item -min_seg_duration @var{microseconds}

+Set the segment length in microseconds.

+@item -window_size @var{size}

+Set the maximum number of segments kept in the manifest.

+@item -extra_window_size @var{size}

+Set the maximum number of segments kept outside of the manifest before removing from disk.

+@item -remove_at_exit @var{remove}

+Enable (1) or disable (0) removal of all segments when finished.

+@item -use_template @var{template}

+Enable (1) or disable (0) use of SegmentTemplate instead of SegmentList.

+@item -use_timeline @var{timeline}

+Enable (1) or disable (0) use of SegmentTimeline in SegmentTemplate.

+@item -single_file @var{single_file}

+Enable (1) or disable (0) storing all segments in one file, accessed using byte ranges.

+@item -single_file_name @var{file_name}

+DASH-templated name to be used for baseURL. Implies @var{single_file} set to "1".

+@item -init_seg_name @var{init_name}

+DASH-templated name to used for the initialization segment. Default is "init-stream$RepresentationID$.m4s"

+@item -media_seg_name @var{segment_name}

+DASH-templated name to used for the media segments. Default is "chunk-stream$RepresentationID$-$Number%05d$.m4s"

+@item -utc_timing_url @var{utc_url}

+URL of the page that will return the UTC timestamp in ISO format. Example: "https://time.akamai.com/?iso"

+@item -adaptation_sets @var{adaptation_sets}

+Assign streams to AdaptationSets. Syntax is "id=x,streams=a,b,c id=y,streams=d,e" with x and y being the IDs

+of the adaptation sets and a,b,c,d and e are the indices of the mapped streams.

+

+To map all video (or audio) streams to an AdaptationSet, "v" (or "a") can be used as stream identifier instead of IDs.

+

+When no assignment is defined, this defaults to an AdaptationSet for each stream.
