@dongrixinyu would this event help?

• Hls.Events.FRAG_PARSING_USERDATA - fired when parsing sei text is completed data: { id : demuxer id, frag: fragment object, samples : [ sei samples pes ] }

Found it in the list of runtime events

@dongrixinyu I'm not sure the answer to your 2 questions.

Did you try this code above with the Hls.Events.FRAG_PARSING_USERDATA listener? What were the results?

@robwalch I set SEI user data in my stream and then I able to read them with FRAG_PARSING_USERDATA events but it is only possible for HLS streams with MPEGTS segments. When I try to use FMP4 (with ffmpeg's hls muxer) or M4S (which are generated by the ffmpeg's dash muxer) user data samples are always emty.
