I think the error is pretty clear. You can’t republish a stream track.

How are you publishing the audio and video?

3

i copied the code here.
https://js.do/code/sdcksjcn

4

Please, copy your code well formatted. It’s difficult to read.

6

Before publish a new publisher, you have to unpublish the publisher published.

Please, read the docs https://docs.openvidu.io/en/2.15.0/cheatsheet/publish-unpublish/

7

but i want the publisher could publish many media
for example the screen and the audio and the webcam

8

You can. But you must initialize a new Connection for the same client: each Publisher requires its own connection. Genreate a new token to be used to call a second time Session.connect(TOKEN), and then call Session.publish() for the new Publisher.

9

i want the user can publish three time and you said i should take token for each publish
and i should get three token for each user?

10

If you want each final user to be able to publish 3 times, then you will need to establish 3 different connections to OpenVidu for the same browser. That requires 3 different tokens, yes. OpenVidu Call application works in this way to be able to publish both webcam and screenshare at the same time: https://demos.openvidu.io/openvidu-call/#/
