Create the SDK object with CreateZoomVideoSDKObj, initialize with ZoomVideoSDKInitParams, add a delegate listener, then call joinSession with a JWT token. Set audioOption.connect to false and start audio in the onSessionJoin callback for reliability.

The SDK delivers callbacks through Windows messages, so console apps and custom main loops must run a message pump using PeekMessage, TranslateMessage, and DispatchMessage. Without it, joinSession appears to succeed but onSessionJoin never fires.

Use the Canvas API for standard video display since the SDK renders hardware-accelerated video directly to your HWND in three lines of code. Use the Raw Data Pipe only when you need YUV420 frame access for effects, AI processing, or custom recording.

Yes, through a C++/CLI wrapper that bridges the native SDK to .NET Framework 4.8 applications. The Skill documents eight wrapper patterns covering gcroot callbacks, IDisposable cleanup, string marshaling, and UI thread dispatch.

Error 2 means the video stream is not ready when you subscribe. Subscribe inside the onUserVideoStatusChanged callback after confirming the user's video status is on, rather than subscribing immediately in onUserJoin.

The delegate interface has 80+ pure virtual methods and all must be implemented, even as empty bodies. Check the SDK version's zoom_video_sdk_delegate_interface.h for the exact list, since the interface changes between releases.
