what chunk is transmitted when, is not important technically, (programatically, it is doable, i do not know how to call that properly)

it is ONLY important when you need to not have people (SWARM) finishing downloading of torrent then closing torrent client app and not sending data chunks to next person.

BUT everyone is saying it is stream and has to be instant showing of picture/video.

so i do not understand why all those people in other comments are caring about state of swarm if we do have thousands people watching and everybody is saying there are big amounts of people watching but still caring about swarm..

(swarm thing is important with normal use case of BitTorrent, irrelevant for streaming)

i understand what they are saying, they do not understand that they are saying nonsense.
