## Project Preferences & Learnings

> **IMPORTANT**: These are hard-won preferences from real project experience. Follow these when creating new projects.

### Do NOT use CMake — Use native Visual Studio `.vcxproj`

**Always create a native Visual Studio `.sln` + `.vcxproj` project**, not a CMake project. Reasons:
- More standard and familiar for Windows C++ developers
- Developers can double-click the `.sln` to open in Visual Studio immediately
- Project settings (include dirs, lib dirs, preprocessor defines) are easier to see and edit in the VS Property Pages UI
- No extra CMake tooling or configuration step required
- Friendlier and easier for developers to understand and maintain

### `config.json` must be visible in Solution Explorer

The `config.json` file (containing `sdk_jwt`, `meeting_number`, `passcode`) must be:
1. **Included in the `.vcxproj`** as a `<None>` item with `<CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>`
2. **Placed in a "Config" filter** in the `.vcxproj.filters` file so it appears under a "Config" folder in Solution Explorer
3. **Easily editable** by developers directly from Solution Explorer — they should never have to hunt for it in File Explorer

Example `.vcxproj` entry:
```xml
<ItemGroup>
  <None Include="config.json">
    <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
  </None>
</ItemGroup>
```

Example `.vcxproj.filters` entry:
```xml
<ItemGroup>
  <Filter Include="Config">
    <UniqueIdentifier>{GUID-HERE}</UniqueIdentifier>
  </Filter>
</ItemGroup>
<ItemGroup>
  <None Include="config.json">
    <Filter>Config</Filter>
  </None>
</ItemGroup>
```

## Overview

The Windows SDK is a **C++ native SDK** designed for:
- **Desktop applications** - Native Windows apps with full UI control
- **Headless bots** - Join meetings without UI
- **Raw media access** - Capture/send audio/video streams
- **Local recording** - Record meetings locally or to cloud

### Key Architectural Insight

The SDK follows a **universal 3-step pattern** for every feature:
1. **Get controller** (singleton): `meetingService->Get[Feature]Controller()`
2. **Implement event listener**: `class MyListener : public I[Feature]Event { ... }`
3. **Register and use**: `controller->SetEvent(listener)` then call methods

**This works for ALL features**: audio, video, chat, recording, participants, screen sharing, breakout rooms, webinars, Q&A, polling, whiteboard, and 20+ more!

## Quick Start

### 1. Download Windows SDK

Download from [Zoom Marketplace](https://marketplace.zoom.us/):
- Extract `zoom-meeting-sdk-windows_x86_64-{version}.zip`

### 2. Setup Project Structure

```
your-project/
  YourApp/
    SDK/
      x64/
        bin/          # DLL files and dependencies
        h/            # Header files
        lib/          # sdk.lib
      x86/
        bin/
        h/
        lib/
    YourApp.cpp
    YourApp.vcxproj
    config.json
```

Copy SDK files:
```cmd
xcopy /E /I sdk-package\x64 your-project\YourApp\SDK\x64\
xcopy /E /I sdk-package\x86 your-project\YourApp\SDK\x86\
```

### 3. Install Dependencies (vcpkg)

```powershell
# Install vcpkg
git clone https://github.com/Microsoft/vcpkg.git C:\vcpkg
cd C:\vcpkg
.\bootstrap-vcpkg.bat
.\vcpkg integrate install

# Install dependencies
.\vcpkg install jsoncpp:x64-windows
.\vcpkg install curl:x64-windows
```

### 4. Configure Visual Studio Project

**Project Properties → C/C++ → General → Additional Include Directories:**
```
$(SolutionDir)SDK\$(PlatformTarget)\h
C:\vcpkg\packages\jsoncpp_x64-windows\include
C:\vcpkg\packages\curl_x64-windows\include
```

**Project Properties → Linker → General → Additional Library Directories:**
```
$(SolutionDir)SDK\$(PlatformTarget)\lib
```

**Project Properties → Linker → Input → Additional Dependencies:**
```
sdk.lib
```

**Post-Build Event** (Copy DLLs to output):
```cmd
xcopy /Y /D "$(SolutionDir)SDK\$(PlatformTarget)\bin\*.*" "$(OutDir)"
```

### 5. Configure Credentials

Create `config.json`:
```json
{
  "sdk_jwt": "YOUR_JWT_TOKEN",
  "meeting_number": "1234567890",
  "passcode": "password123",
  "zak": ""
}
```

### 6. Build & Run

- Open solution in Visual Studio
- Select x64 or x86 configuration
- Press F5 to build and run

## Core Workflow

```
┌─────────────┐    ┌─────────────┐    ┌─────────────┐    ┌─────────────┐
│  InitSDK    │───►│  AuthSDK    │───►│ JoinMeeting │───►│ Raw Data    │
│             │    │  (JWT)      │    │             │    │ Subscribe   │
└─────────────┘    └─────────────┘    └─────────────┘    └─────────────┘
                         │                   │
                         ▼                   ▼
                   OnAuthComplete      onInMeeting
                     callback           callback
```

**⚠️ CRITICAL**: Add Windows message loop or callbacks won't fire!
```cpp
while (!done) {
    MSG msg;
    while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
    }
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
}
```
See: [Windows Message Loop Guide](troubleshooting/windows-message-loop.md)

> - [Raw Video Capture](examples/raw-video-capture.md) - Complete video capture
> - [SDK Architecture Pattern](concepts/sdk-architecture-pattern.md) - Implement any feature

### Important: Include Order

**CRITICAL**: Include headers in this exact order or you'll get build errors:

```cpp
#include <windows.h>      // MUST be first
#include <cstdint>         // MUST be second (SDK headers use uint32_t)
// ... other standard headers ...
#include <zoom_sdk.h>
#include <meeting_service_components/meeting_audio_interface.h>  // BEFORE participants!
#include <meeting_service_components/meeting_participants_ctrl_interface.h>
```

See: [Build Errors Guide](troubleshooting/build-errors.md) for all dependency fixes.

### 1. Initialize SDK

```cpp
#include <windows.h>
#include <cstdint>
#include <zoom_sdk.h>

using namespace ZOOM_SDK_NAMESPACE;

bool InitMeetingSDK() {
    InitParam initParam;
    initParam.strWebDomain = L"https://zoom.us";
    initParam.strSupportUrl = L"https://zoom.us";
    initParam.emLanguageID = LANGUAGE_English;
    initParam.enableLogByDefault = true;
    initParam.enableGenerateDump = true;

    SDKError err = InitSDK(initParam);
    if (err != SDKERR_SUCCESS) {
        std::wcout << L"InitSDK failed: " << err << std::endl;
        return false;
    }
    return true;
}
```

### 2. Authenticate with JWT

```cpp
#include <windows.h>
#include <cstdint>
#include <auth_service_interface.h>
#include "AuthServiceEventListener.h"

IAuthService* authService = nullptr;

void OnAuthenticationComplete() {
    std::cout << "Authentication successful!" << std::endl;
    JoinMeeting();  // Proceed to join meeting
}

bool AuthenticateSDK(const std::wstring& jwtToken) {
    CreateAuthService(&authService);
    if (!authService) return false;

    // Set event listener BEFORE calling SDKAuth
    authService->SetEvent(new AuthServiceEventListener(&OnAuthenticationComplete));

    // Authenticate with JWT
    AuthContext authContext;
    authContext.jwt_token = jwtToken.c_str();

    SDKError err = authService->SDKAuth(authContext);
    if (err != SDKERR_SUCCESS) {
        std::wcout << L"SDKAuth failed: " << err << std::endl;
        return false;
    }

    // CRITICAL: Add message loop or callback won't fire!
    // See complete example: examples/authentication-pattern.md

    return true;
}
```

**AuthServiceEventListener.h:**
```cpp
#include <windows.h>
#include <cstdint>
#include <auth_service_interface.h>
#include <iostream>

using namespace ZOOM_SDK_NAMESPACE;

class AuthServiceEventListener : public IAuthServiceEvent {
public:
    AuthServiceEventListener(void (*onComplete)())
        : onAuthComplete(onComplete) {}

    void onAuthenticationReturn(AuthResult ret) override {
        if (ret == AUTHRET_SUCCESS && onAuthComplete) {
            onAuthComplete();
        } else {
            std::cout << "Auth failed: " << ret << std::endl;
        }
    }

    // Must implement ALL pure virtual methods (6 total)
    void onLoginReturnWithReason(LOGINSTATUS ret, IAccountInfo* info, LoginFailReason reason) override {}
    void onLogout() override {}
    void onZoomIdentityExpired() override {}
    void onZoomAuthIdentityExpired() override {}
#if defined(WIN32)
    void onNotificationServiceStatus(SDKNotificationServiceStatus status, SDKNotificationServiceError error) override {}
#endif

private:
    void (*onAuthComplete)();
};
```

### 3. Join Meeting

```cpp
#include <meeting_service_interface.h>
#include "MeetingServiceEventListener.h"

IMeetingService* meetingService = nullptr;

void OnMeetingJoined() {
    std::cout << "Joining meeting..." << std::endl;
}

void OnInMeeting() {
    std::cout << "In meeting now!" << std::endl;
    // Start raw data capture here
}

void OnMeetingEnds() {
    std::cout << "Meeting ended" << std::endl;
}

bool JoinMeeting(UINT64 meetingNumber, const std::wstring& password) {
    CreateMeetingService(&meetingService);
    if (!meetingService) return false;

    // Set event listener
    meetingService->SetEvent(
        new MeetingServiceEventListener(&OnMeetingJoined, &OnMeetingEnds, &OnInMeeting)
    );

    // Prepare join parameters
    JoinParam joinParam;
    joinParam.userType = SDK_UT_WITHOUT_LOGIN;

    JoinParam4WithoutLogin& params = joinParam.param.withoutloginuserJoin;
    params.meetingNumber = meetingNumber;
    params.userName = L"Bot User";
    params.psw = password.c_str();
    params.isVideoOff = false;
    params.isAudioOff = false;

    SDKError err = meetingService->Join(joinParam);
    if (err != SDKERR_SUCCESS) {
        std::wcout << L"Join failed: " << err << std::endl;
        return false;
    }
    return true;
}
```

**MeetingServiceEventListener.h:**
```cpp
#include <windows.h>
#include <cstdint>
#include <meeting_service_interface.h>
#include <iostream>

using namespace ZOOM_SDK_NAMESPACE;

class MeetingServiceEventListener : public IMeetingServiceEvent {
public:
    MeetingServiceEventListener(
        void (*onJoined)(),
        void (*onEnded)(),
        void (*onInMeeting)()
    ) : onMeetingJoined(onJoined),
        onMeetingEnded(onEnded),
        onInMeetingCallback(onInMeeting) {}

    void onMeetingStatusChanged(MeetingStatus status, int iResult) override {
        if (status == MEETING_STATUS_CONNECTING) {
            if (onMeetingJoined) onMeetingJoined();
        }
        else if (status == MEETING_STATUS_INMEETING) {
            if (onInMeetingCallback) onInMeetingCallback();
        }
        else if (status == MEETING_STATUS_ENDED) {
            if (onMeetingEnded) onMeetingEnded();
        }

    void (*onMeetingEnded)();
    void (*onInMeetingCallback)();
};
```

### 4. Subscribe to Raw Video

```cpp
#include <windows.h>
#include <cstdint>
#include <rawdata/zoom_rawdata_api.h>
#include <rawdata/rawdata_renderer_interface.h>
#include <zoom_sdk_raw_data_def.h>  // REQUIRED for YUVRawDataI420
#include "ZoomSDKRendererDelegate.h"

IZoomSDKRenderer* videoHelper = nullptr;
ZoomSDKRendererDelegate* videoSource = new ZoomSDKRendererDelegate();

bool StartVideoCapture(uint32_t userId) {
    // STEP 1: Start raw recording FIRST (required!)
    IMeetingRecordingController* recordCtrl =
        meetingService->GetMeetingRecordingController();

    SDKError canStart = recordCtrl->CanStartRawRecording();
    if (canStart != SDKERR_SUCCESS) {
        std::cout << "Cannot start recording: " << canStart << std::endl;
        return false;
    }

    recordCtrl->StartRawRecording();

    // Wait for recording to initialize
    std::this_thread::sleep_for(std::chrono::milliseconds(500));

    // STEP 2: Create renderer
    SDKError err = createRenderer(&videoHelper, videoSource);
    if (err != SDKERR_SUCCESS || !videoHelper) {
        std::cout << "createRenderer failed: " << err << std::endl;
        return false;
    }

    // STEP 3: Set resolution and subscribe
    videoHelper->setRawDataResolution(ZoomSDKResolution_720P);
    err = videoHelper->subscribe(userId, RAW_DATA_TYPE_VIDEO);
    if (err != SDKERR_SUCCESS) {
        std::cout << "Subscribe failed: " << err << std::endl;
        return false;
    }

    std::cout << "Video capture started! Frames arrive in onRawDataFrameReceived()" << std::endl;
    return true;
}
```

**ZoomSDKRendererDelegate.h:**
```cpp
#include <windows.h>
#include <cstdint>
#include <rawdata/rawdata_renderer_interface.h>
#include <zoom_sdk_raw_data_def.h>
#include <fstream>
#include <iostream>

using namespace ZOOM_SDK_NAMESPACE;

class ZoomSDKRendererDelegate : public IZoomSDKRendererDelegate {
public:
    void onRawDataFrameReceived(YUVRawDataI420* data) override {
        if (!data) return;

        // YUV420 (I420) format: Y plane + U plane + V plane
        int width = data->GetStreamWidth();
        int height = data->GetStreamHeight();

        // Calculate buffer sizes
        // Y = full resolution, U/V = quarter resolution each
        size_t ySize = width * height;
        size_t uvSize = ySize / 4;  // (width/2) * (height/2)

        // Total size: width * height * 1.5 bytes

        // Save to file (playback: ffplay -f rawvideo -pixel_format yuv420p -video_size 1280x720 output.yuv)
        std::ofstream outputFile("output.yuv", std::ios::binary | std::ios::app);
        outputFile.write(data->GetYBuffer(), ySize);    // Brightness
        outputFile.write(data->GetUBuffer(), uvSize);   // Blue-difference
        outputFile.write(data->GetVBuffer(), uvSize);   // Red-difference
        outputFile.close();
    }

    void onRawDataStatusChanged(RawDataStatus status) override {
        std::cout << "Raw data status: " << status << std::endl;
    }

    void onRendererBeDestroyed() override {
        std::cout << "Renderer destroyed" << std::endl;
    }
};
```

### 5. Subscribe to Raw Audio

```cpp
#include <rawdata/rawdata_audio_helper_interface.h>

class ZoomSDKAudioRawDataDelegate : public IZoomSDKAudioRawDataDelegate {
public:
    void onMixedAudioRawDataReceived(AudioRawData* data) override {
        // Process PCM audio (mixed from all participants)
        std::ofstream pcmFile("audio.pcm", std::ios::binary | std::ios::app);
        pcmFile.write((char*)data->GetBuffer(), data->GetBufferLen());
        pcmFile.close();
    }

    void onOneWayAudioRawDataReceived(AudioRawData* data, uint32_t node_id) override {
        // Process audio from specific participant
    }
};

// Subscribe to audio
IZoomSDKAudioRawDataHelper* audioHelper = GetAudioRawdataHelper();
audioHelper->subscribe(new ZoomSDKAudioRawDataDelegate());
```

### 6. Main Message Loop (CRITICAL!)

**⚠️ WITHOUT THIS, CALLBACKS WON'T FIRE!**

```cpp
#include <windows.h>
#include <thread>
#include <chrono>

int main() {
    // Initialize COM
    CoInitialize(NULL);

    // Load config and initialize
    LoadConfig();
    InitMeetingSDK();
    AuthenticateSDK(sdk_jwt);

    // CRITICAL: Windows message loop for SDK callbacks
    // SDK uses Windows message pump to dispatch callbacks
    // Without this, callbacks are queued but NEVER fire!
    MSG msg;
    while (!g_exit) {
        // Process all pending Windows messages
        while (PeekMessage(&msg, NULL, 0, 0, PM_REMOVE)) {
            if (msg.message == WM_QUIT) {
                g_exit = true;
                break;
            }
            TranslateMessage(&msg);
            DispatchMessage(&msg);
        }

        // Small sleep to avoid busy-waiting
        std::this_thread::sleep_for(std::chrono::milliseconds(100));
    }

    // Cleanup
    CleanSDK();
    CoUninitialize();

    return 0;
}
```

**Why message loop is critical**: The SDK uses Windows COM/messaging for async callbacks. Without `PeekMessage()`, the SDK queues messages but they're never retrieved/dispatched, so callbacks never execute.

**Symptoms without message loop**:
- Authentication timeout (even with valid JWT)
- Meeting join timeout
- No callback events fire
- Appears like network/auth issue but it's a message loop issue

**See detailed explanation**: [Windows Message Loop Guide](troubleshooting/windows-message-loop.md)

**Complete troubleshooting**: [Common Issues Guide](troubleshooting/common-issues.md)

## How to Implement Any Feature

The SDK has **35+ feature controllers** (audio, video, chat, recording, participants, screen sharing, breakout rooms, webinars, Q&A, polling, whiteboard, captions, AI companion, etc.).

**Universal pattern that works for ALL features:**

1. **Get the controller** (singleton):
   ```cpp
   IMeetingAudioController* audioCtrl = meetingService->GetMeetingAudioController();
   IMeetingChatController* chatCtrl = meetingService->GetMeetingChatController();
   // ... 33 more controllers available
   ```

2. **Implement event listener** (observer pattern):
   ```cpp
   class MyAudioListener : public IMeetingAudioCtrlEvent {
       void onUserAudioStatusChange(IList<IUserAudioStatus*>* lst) override {
           // React to audio events
       }
       // ... implement all required methods
   };
   ```

3. **Register and use**:
   ```cpp
   audioCtrl->SetEvent(new MyAudioListener());
   audioCtrl->MuteAudio(userId, true);  // Use feature
   ```

### Combine Video + Audio
```cmd
ffmpeg -video_size 1280x720 -pixel_format yuv420p -f rawvideo -i output.yuv ^
       -f s16le -ar 32000 -ac 1 -i audio.pcm ^
       -c:v libx264 -c:a aac -shortest output.mp4
```

**Key flags:**
| Flag | Description |
|------|-------------|
| `-video_size WxH` | Frame dimensions (e.g., 1280x720) |
| `-pixel_format yuv420p` | I420/YUV420 planar format |
| `-f rawvideo` | Raw video input (no container) |
| `-f s16le` | Signed 16-bit little-endian PCM |
| `-ar 32000` | Sample rate (Zoom uses 32kHz) |
| `-ac 1` | Mono (use `-ac 2` for stereo) |

## Authentication Requirements (2026 Update)

> **Important**: Beginning **March 2, 2026**, apps joining meetings outside their account must be authorized.

Use one of:
- **App Privilege Token (OBF)** - Recommended for bots (`app_privilege_token` in JoinParam)
- **ZAK Token** - Zoom Access Key (`userZAK` in JoinParam)
- **On Behalf Token** - For specific use cases (`onBehalfToken` in JoinParam)

### 🚨 Most Critical Issues (From Real Debugging)

1. **Callbacks not firing** → Missing Windows message loop (99% of issues)
   - See: [Windows Message Loop Guide](troubleshooting/windows-message-loop.md)

2. **Build errors** → SDK header dependencies (`uint32_t`, `AudioType`, etc.)
   - See: [Build Errors Guide](troubleshooting/build-errors.md)

3. **Abstract class errors** → Missing virtual method implementations
   - See: [Interface Methods Guide](references/interface-methods.md)

### 💡 Key Insight

**Once you learn the 3-step pattern, you can implement ANY of the 35+ features:**
1. Get controller → 2. Implement event listener → 3. Register and use

# Zoom Windows Meeting SDK - Complete Documentation Index

## 🚀 Quick Start Path

**If you're new to the SDK, follow this order:**

1. **Read the architecture pattern** → [concepts/sdk-architecture-pattern.md](concepts/sdk-architecture-pattern.md)
   - This teaches you the universal formula that applies to ALL features
   - Once you understand this, you can implement any feature by reading the `.h` files

2. **Fix build errors** → [troubleshooting/build-errors.md](troubleshooting/build-errors.md)
   - SDK header dependencies issues
   - Required include order

3. **Implement authentication** → [examples/authentication-pattern.md](examples/authentication-pattern.md)
   - Complete working JWT authentication code

4. **Fix callback issues** → [troubleshooting/windows-message-loop.md](troubleshooting/windows-message-loop.md)
   - **CRITICAL**: Why callbacks don't fire without Windows message loop
   - This was the hardest issue to diagnose!

5. **Implement virtual methods** → [references/interface-methods.md](references/interface-methods.md)
   - Complete lists of all required methods
   - How to avoid abstract class errors

6. **Capture video (optional)** → [examples/raw-video-capture.md](examples/raw-video-capture.md)
   - YUV420 format explained
   - Complete raw data capture workflow

7. **Troubleshoot any issues** → [troubleshooting/common-issues.md](troubleshooting/common-issues.md)
