The angle of view of the video changes on its own


After the session starts, the angle of the input content from the camera displayed in the video stream is automatically changed.


After 20 seconds after the call has started, the angle of view of the video displayed by your camera is changed.

No parameter changes or other operations are performed during the call with regard to the input or rendering from the camera.
Please support us in resolving this issue.

The implementation follows the Zoom Developers Guide.

This phenomenon only occurs in certain environments.
And this does not occur in the following environments.


  • Apple Safari


  • Google Chorome
  • Firefox

Let me know if you need any other information to help resolve the glitch.

Is this still happening for you, or have you resolved it?

Hi, Kelly

We tested this using “Zoom Video SDK 1.7.7” and the problem has not improved.


Ping. Any news on this?

thank you

Hey @jun.sugai

Could you help share the model of the camera and detail of the issue( screenshot) if possible?

Would you like to try our sample app and check whether the issue occurs if convenient?
