After join meeting, window not working and not recognizing mic and camera

m.zhang · February 18, 2021, 8:07pm

Description
In my own application, after JWT authentication, I joined the meeting with the meeting service from getMeetingService(). The Meeting Window shows up correctly, but it fails to recognize camera and pickup microphone. (Correct access to microphone and camera have been granted in System Preferences → Security&Privacy). I’ve also modified my info.plist based on the sample application. The UI also semi-freeze in that leave meeting will not close window properly. I couldn’t seem to figure out what went wrong or what is contributing to this behaviour. Can someone help please?

Which Client macOS SDK version?
v5.4.54802.0124

Screenshots

As shown in the image above, clicking on Start Video has no effect. After clicking on Join Audio, a pop up window appears but when adjusting microphone, no audio can be captured/detected.
It also appears like some of the icon did not load appropriately since some of them have LN_XXX instead of the actual name.

Device Information

Device: Macbook Pro
OS: macOS Catalina
Version 10.15.7

Additional context
Console output after Meeting UI shows up:

Hi @m.zhang, thanks for the post.

Can you please verify the Xcode version you are running and whether or not your machine has an M1 chip?

Thanks!

m.zhang · February 18, 2021, 8:26pm

Hi @jon.zoom , I’m using Xcode 10.3 and my mac has an Intel processor (quite a old macbook pro) and not a M1 chip. Also, just a bit more information, on other user’s perspective (let’s say I join the same meeting from a mobile device), the user from the SDK window shows up as “connecting to audio…”

jon.zoom · February 18, 2021, 10:25pm

Hi @m.zhang,

Thanks for confirming. Can you please provide the full SDK log file from your application so that we may investigate further? The file should be located at ~/Library/Logs/${APPLICATION_NAME}. You’ll know you have the correct file if the contents are encrypted.

Thanks!

m.zhang · February 18, 2021, 10:30pm

Hi @jon.zoom , I do see the log and it seems quite unreadable with all the weird characters, which probably means the log file is encrypted. Do you want the raw file or should I decrypt it first? If so, how do I decrypt it? Thanks!

jon.zoom · February 18, 2021, 11:23pm

Hi @m.zhang,

Yes, that’s the one! You can send it as-is to developersupport@zoom.us and we will begin investigating.

Thanks!

m.zhang · February 22, 2021, 2:26pm

Hi @jon.zoom ,

I see on https://support.zoom.us/hc/en-us/requests/9877335 ,the status of the request has been solved. Did I miss your response to this investigation? What did you find out? Thank you so much for your help!

jon.zoom · February 22, 2021, 7:29pm

Hi @m.zhang,

Apologies for the confusion on that. When you send the logs over to our support email, a ticket is automatically created in our tracking system. Since we are working through this on the dev forum, that ticket is essentially a duplicate of this thread, so we typically will close it out.

Regarding the issue, during our investigation we determined that the application appears to have crashed due to something related to your main menu and are working towards a fix. To help us ensure we get the fix right, can you please send a screenshot of your applications main menu?

Thanks!

m.zhang · February 22, 2021, 7:31pm

Hi @jon.zoom , What do you mean by the main menu? Could you elaborate?

m.zhang · February 22, 2021, 9:31pm

Below is the code I’m using. Not sure if this helps or not, but I wasn’t sure if any UI work needs to be done if at the moment I only hope to get the default UI working. Do I need any meeting handlers of some sort?

if isAuthed(){  // After successful JWT authentication
      print("Join meeting without login")
      let meetingNumber = Int64("*******")!
      let userName = "Test User"
      let meetingPasscode = "****"
      
      let sdk: ZoomSDK = ZoomSDK.shared()
      let meetingService = sdk.getMeetingService()
      let joinParams = ZoomSDKJoinMeetingElements()
      joinParams.userType = ZoomSDKUserType_WithoutLogin
      joinParams.webinarToken = nil
      joinParams.participantId = nil
      joinParams.meetingNumber = meetingNumber
      joinParams.displayName = userName;
      joinParams.password = meetingPasscode;
      joinParams.isDirectShare = false;
      joinParams.displayID = 0;
      joinParams.isNoVideo = true;
      joinParams.isNoAuido = true;
      joinParams.vanityID = nil;
      joinParams.zak = nil;
      
      let audioSetting = sdk.getSettingService().getAudioSetting()
      let ret = meetingService?.joinMeeting(joinParams)
      print(ret)
      
    } else {
      print("Authorization must happen before meeting service is available")
    }

jon.zoom · February 22, 2021, 11:54pm

Hi @m.zhang,

The main menu is the NSMenu dropdown menu for your application. You can access it when your application is running through the top toolbar on your machine.

Thanks!

m.zhang · February 23, 2021, 12:46am

Hi @jon.zoom ,
We have purposely made the main menu empty since we wanted to disable user from accessing it. Thus, when our application is running, when mouse over the top bar, click on the name of our application has no effect and does not display a main menu. Does this not work with ZoomSDK default UI? How does this affect ZoomSDK? Thank you!

jon.zoom · February 23, 2021, 8:20pm

Hi @m.zhang, thanks for the additional info.

We will be adding protection against this in the next release. The SDK adds a Meeting menu when in a meeting, so this crash is preventing that from being created.

Thanks!

m.zhang · February 23, 2021, 9:50pm

Hi @jon.zoom ,

That’s great to hear! Thank you for making this improvement! Do you have a rough idea about when the next release is?

m.zhang · February 23, 2021, 10:17pm

Hi @jon.zoom ,

Also, would this behaviour also be present if I’m embedding ZoomSDK with a custom UI? Thanks!

m.zhang · February 25, 2021, 4:47pm

Hi @jon.zoom ,

Could you respond when you get a chance please? Your response is crucial to our development. Thanks!

jon.zoom · February 25, 2021, 6:52pm

Hi @m.zhang,

Please accept my deepest apologies on the delayed response.

Do you have a rough idea about when the next release is?

We do not yet have an exact release date for the next SDK version. Historically we have aimed for a release cadence of every 2-3 months, but we do not guarantee a new release in this time period.

Also, would this behaviour also be present if I’m embedding ZoomSDK with a custom UI? Thanks!

Based on my testing, the same menu is not present in a custom UI.

Thanks!

m.zhang · February 25, 2021, 7:12pm

Hi @jon.zoom ,

I’ll adopt a custom UI then. Thank you very much for your help!

jon.zoom · February 25, 2021, 10:21pm

Always happy to help!

Please don’t hesitate to reach out if you need any further help with the custom UI approach.
