Screen share video freezes

Hello. I am trying to send video buffer using MobileRTCScreenShare.framework from your sample. My frame rate is about 30. But when I watch a meeting the actual frame rate is about 1. Everything is done according to your tutorial (https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/in-meeting-function/zoom-meeting-ui/screen-share)

Hi stas.hryhoriev,

Thanks for using Zoom SDK. Could you provide more info regarding the issue you are facing:

  • What is the SDK version you are using?
  • “My frame rate is about 30. But when I watch a meeting the actual frame rate is about 1.” – Do you mean that when you start the meeting(iOS SDK app?), your frame rate is about 30, and when you use another client(iOS SDK app?) to join the meeting to see the screen share, the frame rate is 1?
  • Could you have a try with our Zoom iOS client and start screen sharing, does this issue also exist?
  • Are you getting any errors? Could you provide SDK log for this?

Thanks!

Hello. I downloaded the latest version of the SDK (from https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/getting-started/install-sdk) which contains an example of using the SDK. Then I add broadcast upload extension to your sample (as in the example https://marketplace.zoom.us/docs/sdk/native-sdks/iOS/mastering-zoom-sdk/in-meeting-function/zoom-meeting-ui/screen-share).Then I launched the application on iPad air 2 using Xcode. It works. Then I used another client to join the meeting to see the screen share. I see my screen in meeting but video lags and freezes. Actual frame rate is about 1. I tried to reproduce this issue on your IOS client app but it is worked fine. I did not get any errors from SDK

Thanks!
