Android SDK Multitrack Conference Join-Rejoin Does Not Work Correctly

[lastpeony]

trafficstars

In the Android SDK multitrack conference, when a participant joins and then subsequently leaves the conference, their video feed is not properly cleared; instead, it becomes frozen. Furthermore, when they rejoin the conference, their video feed does not appear correctly; it remains frozen.

The expected behavior in this scenario is as follows: When a user leaves the conference, their video feed should be cleared, and upon rejoining, their video feed should be added correctly, without remaining frozen.

This issue is being observed in AMS 2.7.0

User report: When user leaves the video conference call and rejoins, his video feed does not get displayed to other users. In this scenario, we checked in the Antmedia server as well, where we are able to see the player video but the same person not in the meeting room.

Hi @KavyashreeBasavesh,

There is no update. We have not space available to schedule this issue. It's going on priority basis and availability as you probably already know.

same issue is happening in WebRTC Android SDK when,

• playing stream with webRTCClient.startStream(STREAM_ID)
• stoping using webRTCClient.stopStream(STREAM_ID)
• again starting stream.

when stoping the stream the frame gets stuck, starting again stream stays stuck at that frame while logs shows that stream is successfully started.
