Zoom Meeting Windows SDK | OnRenderUserChanged in Custom UI Mgr callback was not triggering

Meeting SDK Windows

Hi @kisappdev,

Thanks for the context, I see you posted something similar here and while no one from the Zoom team has gotten back to you yet, I’ll do my best to help in the meantime!

It’s tough to say if this is a bug with the Zoom Windows Meeting SDK or something else. You mentioned onRenderUserChanged isn’t triggering consistently, could you test if other callbacks like onRenderDataTypeChanged is also flaky? If they are, it might point to an issue with how the SDK is initialized

While we wait for the Zoom team to weigh in, here are a couple of options to keep you moving:

  • Workaround: Try using onUserVideoStatusChange from IMeetingVideoCtrlEvent. It’s not as direct as onRenderUserChanged, but it might let you track video status changes tied to the active speaker
  • Revert back to working version: If you’re stuck and need it working ASAP, rolling back to the previous working SDK version would resolve this
