After some time zoom meeting's screen gets delayed

Hello everyone
I am working on a project using zoom mobile SDK and I am working on very low delay but on my app the delay goes higher and higher as time goes… Can you suggest some solution of this problem?
Can we use some sort of dedicated server to solve this or you suggest some other solution.
Thanks…
Tested on : Huawei y7 prime 2019, Motorola turbo 2
Operating System : Android

Hi irfanalijoji,

Thanks for using Zoom SDK. In order to further help you, we might need more information, could you provide the following information:

  1. What is the SDK version you are using?
  2. Based on your description, do you mean that the lagging issue does not exist when the meeting starts, and then the lagging appears and becomes worse as time goes?
  3. Could you provide the steps to reproduce this issue? (If not just simply join a meeting?)
  4. Could you have a try with our demo app and see if the lagging issue still occurs?
  5. Could you provide the SDK logs when this issue occurs?

Thanks!

1-Sir I am using the most recent version of SDK available on Github
2-yes it gets worse as time goes
3-just simply join the meeting and then after some time it get’s delayed also sometimes if you leave and rejoin then this thing also occurs.
4-Yes I tried both of the apps and in both apps lag occurs
5-I didn’t saved any sdk logs and no idea where they are

Hi irfanalijoji,

Thanks for the reply.

We tried to reproduce your issue with our demo app but we are not able to see this issue. It would very helpful if you could provide the SDK logs so that we can further investigate this issue.

Thanks!

Thanks Sir…
Sir I try to explain the scenario…
I tested the app on Motorola Droid turbo 2 Android 7.0 Snapdragon 810 with my app and with zoom app everything went smooth but when I leave the meeting and then rejoined the meeting then it started to delay and delay keeps increasing normally 2 seconds delay to 3 or 4 seconds.
I also tried on huawei Y7 prime 2019 Snapdragon 430 the issue is same.
Then I also tested on emulator and also compared with zoom official app the issue is still the same.
Both apps adds delay after rejoining the meeting.

Sir can you help me in configuring with the VPS with zoom so that I can test with that too?
I have a basic Virtual private Server and want to configure zoom with that server so that I can see the comparison…
I am using CentOS on my VPS.

Hi irfanalijoji,

Thanks for the reply. The behavior you are describing sounds unexpected. Could you provide an SDK log so that we further investigate this issue? The instruction to get the log can be found here: https://marketplace.zoom.us/docs/sdk/native-sdks/android/mastering-zoom-sdk/sdk-initialization#2-log-feature

Thanks!

sure Sir I am sending you the log file
here.

Hi irfanalijoji,

Thanks for the reply. The log you are providing is not the SDK log, which does not include enough information for troubleshooting the issue. Could you provide the SDK log instead?

Also, would like to confirm the issue again, when you say “delay”, do you mean that the meeting joining time gets longer and longer, or do you mean the video shown in the meeting gets more latency and lagging as time goes?

Looking forward to hearing from you. Thanks

Yes Sir I am having the same problem and I don’t know what is the problem I enabled the logs of sdk but not storing these logs anywhere. Let me attach some pictures which will show you the problem.


above shown picture is the when someone joins the meeting but when I leave and then rejoin the meeting then and then I found the proxy lists of Zoom then I set those up and then retested the meeting above picture represents the result after setting up the UDP proxy and then whatever I do the latency remains nearly equal to 400 and delays goes on. Not increases but remains constant

Hi irfanalijoji,

Thanks for the reply and the screenshots. Based on your screenshots, it looks like the case is: Using the Windows Zoom Client to start sharing and using the Android SDK app to join and view the shared content?

After consulting with the engineers, if the latency is less than 1s, then it should be normal since the latency is highly impacted by the network quality and the shared content.

Without the log, we are not able to tell what is the root cause of the issue you are facing, but I have tried to reproduce this same issue on my side but with no luck. Below I am using Zoom Client to share a video, and use iOS SDK sample app(latest) and Android SDK sample app(latest) to join the meeting(one with the cellular network and one with Wifi)

I also tried to perform the same test with users from very far away, the latency gets higher but you won’t feel any latency in actual usage:

Hope this helps. Thanks!
