google chrome - WebRTC screen sharing more than once without reloading page -

-

hi i´m developing webrtc app. "video adviser", clients make video call sellers, , want sellers share screen (without losing video call). managed make work together, when client finishes call, , new client arrives, when seller tries share screen again (with new client) error occurs.

the error following one: enter image description here

i think problem screen sharing api not support ending , reopening screen share without refreshing window (this want, keep seller online , listening once finishes calls without refreshing entire page).

this code cancel screen sharing once client leaves call:

if(yourconn.getlocalstreams()[1] != null){        var screenstreaming = yourconn.getlocalstreams()[1];       yourconn.removestream(screenstreaming);       screenstreaming.gettracks().foreach(track => track.stop()); }

i know code stops succesfully screen sharing dont understand why when create new screen sharing stream, error posted appears. need help.

by way, im using chrome.

thanks reading , sorry if dont asked clearly, first question.

starting , stopping screensharing possible more once. invalidstateerror sounds (vaguely) trying reuse id choosedesktopmedia passed in chromemediasourceid more once. not possible afaik , need call choosedesktopmedia again (and let user select screen again)
