I want to show a preview video before joining the session. The description in the
ZoomInstantSDKVideoCanvas.h header file states the following:
Call the function to subscribe video or share data. You can subscribe your ‘preview video’ data with userid=0 before entering the session, you can just call it after you called “joinSession:”. Otherwise, you can subscribe video or share data using the real userid in callback “onUserJoin:”.
I’m not sure if I understand the description right. I assumed
userid=0 means the user instance of
mySelf. But I can’t get an instance if I’m not in a session.
Is there a way to show a preview of the local video?
