Hi,

I would like to know if we can add a characteristics in the HLS manifest, an equivalent of the dash role, used for the accessibility.

https://datatracker.ietf.org/doc/html/rfc8216#section-8.9

I tried with "udta_tagc" filter but there are no characteristics in the master hls.

`gpac -i audio_fr.mp4:#HLSGroup=Francais 
-i video.mp4 
-i audio_fr_dv.mp4:#udta_tagc="public.accessibility.describes-video":#HLSGroup=Francais_DV 
-o output/vod.m3u8:profile=onDemand
`

Thank you!
