Note
Audio and video parameters aren’t applicable to the level and should instead be set in each parameter.

Parameter	Description	Available Values	Default Value
duration_precision	Specify the number of decimal accuracy for the duration of the playlist file.	Integer	0
segment_duration	Specify the duration to split output into segment files, measured in seconds.	Positive float number	9.0
fragment_duration	Specify the duration of fMP4 fragment inside of segment file, measured in seconds.	Positive integer number	equals to <segment_duration />
pack_files	Specify whether to package output in compressed file.	yes, no	yes
pack_type	Specify the type of compressed file to package output.	tar, zip	tar
pack_each_stream	Specify whether or not to package each stream in its own file.	yes, no	no
encryption	Enable AES-128 encryption.	yes, no	no
encryption_method	Specify the encryption method used.	advanced_hls: aes-128-cbc, sample-aes fmp4_hls: aes-128-cbc, mpeg_cbcs, mpeg_cens, mpeg_cbc1, mpeg_cenc advanced_dash, advanced_mss, advanced_fmp4: mpeg_cbcs, mpeg_cens, mpeg_cbc1, mpeg_cenc	advanced_hls, fmp4_hls: aes-128-cbc advanced_fmp4, advanced_dash, advanced_mss: mpeg_cenc
encryption_key	Specify the encryption key.	32 hexidecimal characters ([0-9a-f])	none
encryption_key_file	URL to encryption key file.	Valid URL.	none
encryption_iv	Specify the encryption initialization vector.	32 hexidecimal characters ([0-9a-f]).	aes-128-cbc – sequence number of the segment file, sample-aes – randomly generated value
segmenter	Specify which segmenter to use.	v1 – This is the segmenter bundled with FFMPEG and carries significant overhead (as much as 27% with a 364kbps file or 17.3% with a 864kbps file!), and generated several warnings. v2 – This is based on HTTP Live Segmenter tool. It carries with it the same overhead, but generates far fewer warnings. v3 – This version, we call tsparser was built in-house from the ground up to be optimized for our cloud infrastructure. This has significantly less overhead (5.8% with a 364kbps file or 3.8% with a 864kbps file), and does not generate any warnings. dolby_segmenter – Dolby Media Generator segmenter(dolby_segmenter) will update libfaac audio codec to dolby_aac, in case libfaac codec specified. In case copy specified as audio_codec then source audio codec will be tried. In case iframe stream requested then v3 segmenter wil be used.
playlist_version	Specify the version of the m3u8 playlist file.	Integer(EXT-X-VERSION)	none
merge_small_segments	Merge the next chunk with the previous chunk if previous length is less than one second.	yes, no	no
dash_profile	Specify which dash output profile to use.	ondemand — urn:mpeg:dash:profile:isoff-on-demand:2011, live — urn:mpeg:dash:profile:isoff-live:2011, live_static — live with mpd@type=static	ondemand
cmaf_conformant	This will create an output that is CMAF conformant.	yes, no	no
reduce_structural_overhead	Perform reducing mpeg-ts structural overhead.	yes, no	yes
add_audio_only	Add an audio only stream to master HLS manifest.	yes, no	yes
init_extension	Initialization file's extension.	string (max length: 4 characters)	mp4
segment_extension	Segment file's extension.	string (max length: 4 characters)	m4s
split_segments	Split output to segments	yes, no	yes
widevine_drm	Apply Widevine DRM for whole output	yes. no	no
playready_drm	Apply PlayReady DRM for whole output	yes. no	no
hls_manifests	Create HLS manifests	yes. no	yes
dash_manifests	Create DASH manifests	yes. no	yes
mss_manifests	Create MSS manifests	yes. no	no
segment_template	Select which SegmentTemplate placeholder will be used	number – $Number$ time – $Time$	number
output_json	Upload output format processing summary to the output destination or the specified URL	yes, Valid URL	none
disable_alternate_source_index	Disable adding an alternate source index to the segment name	yes, no	no
