Hey @bharat.bhadresha,

Thanks for sharing the logs. It looks like there’s an audio stream that’s missing here. Given that you aren’t receiving the stream, there’s a few ways to go about debugging this:

Alternatively, you could use a third party like Recall.ai which makes it easy to get meeting data like video and audio

@amanda-recallai Thank you for your response, the docs you linked are of video sdk but I am using meeting sdk, I doubt if I have to subscribe as meeting sdk should internally handle it.

This issue is in this version only because previous version doesn’t have webrtc.

Hey @bharat.bhadresha
Thanks for reaching out to us..
Allow me some time to test this on my end.
Have you tried using our sample app to test this issue?

5

@elisa.zoom

Yes we have tested this on sample app also.

The issue mostly surfaces for meeting duration of more than 30 minutes.

Hey @bharat.bhadresha
So this issue only happens when you pass video_webrtc_mode:1 and only for meetings over 30 minutes?
Is this happening when passing video_webrtc_mode:0 or when not passing it at all?

7

This issue also happens if I pass video_webrtc_mode:0 .

I am not sure what conditions causes this but it happened to some of our test meetings.
I can DM the meeting ids if needed for investigation.

Hi @bharat.bhadresha
That would be great.
I tried replicating this issue on my end using our sample app that’s using version 3.13.2 and I was not able to reproduce the issue
Could you try using the 3.13.2 version and if this happens, please share the same browser errors, along with a meeting id

9

I tried with latest SDK too and still got the same issue.

I have the browser log and meeting id.
Please start a DM thread so I can post the information there.

Let me send you a DM
