Zoom Meeting SDK iPad Problem w/ Audio/Video

Meeting SDK Web

SDK Version: Latest
Browser: Safari
Device: iPad 7th generation
Users connected: 75 users

  • During the meeting, the audio suddenly cuts out and becomes inaudible, and the camera won’t turn on. This doesn’t happen to everyone, just a few users it seems. (Mostly users on iPads, possibly ones using older generation)
    → They leave the meeting and rejoin.
    → Things remain stable for a while, but then the same issue happens again (audio cuts out, camera doesn’t turn on).
    This reportedly happens every 20–30 minutes.

The timing when things become unstable seems to be:

  1. When everyone unmutes their mic at the start for greetings.
  2. When several people are called on at once and asked to unmute and present.

So it seems to be when everyone is unmuting/turning on their video, a few users have trouble speaking/showing their video.

I’m not sure if this matters, but the server is running on a EC2 t3.medium instance.

Hi @eidokun would you be able to DM me a meeting ID of a meeting where this issue occurred?

3

How do I send a DM here? Sorry, I’m not familiar.

Any update on this?
I’ve noticed the main issue here is when several users try to unmute at once the meeting becomes unstable for about 30~60 seconds and voices are not audible.

Hi @eidokun sry for the wait. I checked the meeting you sent me I see there are 24 users who experienced network issues. Some of these 24 are the same user. Regarding the server you mentioned, is this only serving the website containing the SDK or is it hosting zoom meetings as a meeting connector?

Would having some users switch to a higher performing machine the fix the issue?? Most of them are using tablets/chromebooks, Would the webrtc side have troubling handling the load of everyone unmuting at once on a lower spec machine?

I believe a higher spec machine or lower load on browser resources could show an improvement. We also have an option to switch to webrtc media handling in the SDK that could help lower spec clients.

  1. By higher spec do you mean client side or server side?
  2. How would I go about switching to webrtc media handling?

@eidokun Depending where you believe the network bottleneck would be, in this case if the website is simply being served to your customers, a lighter browser and/or better network can be recommended if they experience issues. WebRTC can also be used to in parallel. See this guide for enabling it.
