Webinars succeed with Account A, but fail when conducted with Account B.

I created an application using C++ and MeetingSDK on Linux.

Webinars run normally on Account A, which is capable of hosting them.
However, when switching to Account B, which is also capable of hosting webinars, and running a webinar, after a short time,
IZoomSDKVirtualAudioMicEvent::onMicUninitialized is called, the webinar is terminated,
and the session is forcibly ended by the Zoom server.
The time at which the session is forcibly ended varies.

When running the webinar on multiple machines using Account A, it was never forcibly terminated.

The only possible cause seems to be the account itself.
Could this be violating developer account restrictions?
If there is a page explaining these restrictions, I would appreciate it if you could let me know.

@takeshi do you have the logs captured for this expected exit?

Thank you your help!

We have logs like the following.

@takeshi there should be some logs at ~/.zoomsdk/logs/
I need one which is associated with the unexpected behavior

The suspected cause has been identified, so I would like to report it.

Both Account A and Account B have contracted Zoom Webinars capable of sustaining 30-hour events.
Both accounts streamed video and audio for 7 hours using IZoomSDKVirtualAudioMicEvent and IZoomSDKVirtualAudioMicEvent.

Account A, which successfully completed the 7-hour stream, obtained the Webinar ID via URL Zoom home page webinar.
The logs at that time were as follows:

IZoomSDKVirtualAudioMicEvent::onMicStartSend
IZoomSDKVideoSource::onStartSend

[My Application is End]

Meanwhile, Account B, which could not complete the 7-hour broadcast, obtained the Meeting ID at URL Zoom home page meeting.
The logs at that time are as follows:

IZoomSDKVirtualAudioMicEvent::onMicStartSend
IZoomSDKVideoSource::onStartSend

IZoomSDKVirtualAudioMicEvent::onMicStopSend
IZoomSDKVirtualAudioMicEvent::onUninitialized
IZoomSDKVideoSource::onStopSend
IZoomSDKVideoSource::onUninitialized

[My Application is End]

Unexpectedly, IZoomSDKVirtualAudioMicEvent::onUninitialized and IZoomSDKVideoSource::onUninitialized were called,
causing the application to lose the ability to send video and audio mid-session.
The timing of these calls also varied significantly.
Sometimes they were called after about 40 minutes, while other times they were called after 4 hours had passed.

In other words,
even though it’s a paid account capable of webinars, when running in meeting mode,
midway through,
IZoomSDKVirtualAudioMicEvent::onUninitialized and IZoomSDKVideoSource::onUninitialized are called,
causing the application to be forced to close.

Is this intended behavior?
Or is it a bug?
I would appreciate your response on this point.


>there should be some logs at ~/.zoomsdk/logs/
I confirmed they exist.
The header of the latest file contained the following fields.
What information should I provide?

@takeshi i need the entire file, could you upload somewhere? I’ll PM you

Is this acceptable?
The file size is 1.3MB as a zip file.

If you need anything else, please let me know.

Issue was resolved after re-testing on account . Please raise another thread if it arises again @takeshi
