Duplicate participants on reconnection

Video SDK Web
1

Hey @vic.yang, @tommy

Seems like there one possible bug in SDK failover flow,

Issue:
When user disconnects the call manually when there is no network connection, and rejoins when network comes back, then sometimes there is a duplicate participant in the Zoom session as Zoom SDK was not able to remove previously disconnected user from the session.

Sharing few session ID where the issue was observed:
r57mlsxlRCK1ma3e3DjVrA== , X9VjSspjSxuBbcGkcyWHbg==

Which Web Video SDK version?
1.2.3

Device

  • Device: Macbook Pro, Windows 10 Pro
  • Browser: Chrome (100.0.4896.127 (Official Build) (x86_64)
    )

Hey @shoaib

Thanks for your feedback.

It’s similar to the scenario I mentioned in this thread How to handle internet disconnection properly - #14 by vic.yang. The manually rejoined user is treated as a new participant, and the duplicate participant will disappear within 2 minutes.

Thanks
Vic

Hey @vic.yang,

Thanks for the fast reply.

Yes, but I also think that ideally It should not happen right? because users don’t know that duplicate participant will disappear within 2 minutes. (The issue was reported by few of our users only)

Also, we are noticing in some cases that after that duplicate user gets disappear (after 2 mins) remote participant’s video gets blanked (for the user who got reconnected) and only comes back when remote user toggle’s video.
Some of the affected sessions from the above issue: q14QZ7ngRJKhvkFQNHXetQ==, W+fvXXX+Tbmf0JfirJ6NOg==

Also, there were no errors in the console.

@tommy @vic.yang Not sure about the reason of the issue but It seems like SDK’s reconnection flow still have some issues.
