# Zoom Meeting SDK - Linux Development

Expert guidance for building headless meeting bots with the Zoom Meeting SDK on Linux. This SDK enables server-side meeting participation, raw media capture, transcription, and AI-powered meeting automation.

## How to Build a Meeting Bot That Automatically Joins and Records

Use this skill when the requirement is:
- visible bot joins a real Zoom meeting
- the bot records raw media itself
- or the bot triggers a Zoom-managed cloud-recording workflow after join

Skill chain:
- primary: `meeting-sdk/linux`
- add `zoom-rest-api` for OBF/ZAK lookup, scheduling, or cloud-recording settings
- add `zoom-webhooks` when post-meeting cloud recording retrieval is required

Minimal raw-recording flow:

```cpp
JoinParam join_param;
join_param.userType = SDK_UT_WITHOUT_LOGIN;
auto& params = join_param.param.withoutloginuserJoin;
params.meetingNumber = meeting_number;
params.userName = "Recording Bot";
params.psw = meeting_password.c_str();
params.app_privilege_token = obf_token.c_str();

SDKError join_err = meeting_service->Join(join_param);
if (join_err != SDKERR_SUCCESS) {
    throw std::runtime_error("join_failed");
}

// In MEETING_STATUS_INMEETING callback:
auto* record_ctrl = meeting_service->GetMeetingRecordingController();
if (!record_ctrl) {
    throw std::runtime_error("recording_controller_unavailable");
}

if (record_ctrl->CanStartRawRecording() != SDKERR_SUCCESS) {
    throw std::runtime_error("raw_recording_not_permitted");
}

SDKError record_err = record_ctrl->StartRawRecording();
if (record_err != SDKERR_SUCCESS) {
    throw std::runtime_error("start_raw_recording_failed");
}

GetAudioRawdataHelper()->subscribe(new MyAudioDelegate());
```

Use **raw recording** when the bot must own PCM/YUV media or feed an AI pipeline directly.
Use **cloud recording + webhooks** when the requirement is Zoom-managed MP4/M4A/transcript assets after the meeting.

## Routing Rule for Bots

If the user asks to build a bot that **automatically joins a Zoom meeting and records it**, start with
[meeting-sdk-bot.md](meeting-sdk-bot.md).

- Use **Meeting SDK Linux** for the visible participant, join flow, and raw recording control.
- Chain **zoom-rest-api** when the bot must fetch OBF/ZAK tokens, schedule meetings, or enable account-side recording settings.
- Chain **zoom-webhooks** when the requirement is Zoom cloud recording retrieval after meeting end.

## SDK Overview

The Zoom Meeting SDK for Linux is a **C++ library optimized for headless server environments**:
- **Headless Operation**: No GUI required, perfect for Docker/cloud
- **Raw Data Access**: YUV420 video, PCM audio at 32kHz
- **GLib Event Loop**: Async event handling for callbacks
- **Docker-Ready**: Pre-configured Dockerfiles for CentOS/Ubuntu
- **PulseAudio Integration**: Virtual audio devices for headless environments

### Key Differences from Video SDK

| Feature | Meeting SDK (Linux) | Video SDK |
|---------|-------------------|-----------|
| **Primary Use** | Join existing meetings as bot | Host custom video sessions |
| **Visibility** | Visible participant | Session participant |
| **UI** | Headless (no UI) | Optional custom UI |
| **Authentication** | JWT + OBF/ZAK for external meetings | JWT only |
| **Recording Control** | `StartRawRecording()` required | Direct raw data access |
| **Platform** | Linux only | Windows, macOS, iOS, Android |

## Prerequisites

## Quick Start

### 1. Download & Extract SDK

```bash
# Download from https://marketplace.zoom.us/
tar xzf zoom-meeting-sdk-linux_x86_64-{version}.tar

# Organize files
mkdir -p demo/include/h demo/lib/zoom_meeting_sdk
cp -r h/* demo/include/h/
cp lib*.so demo/lib/zoom_meeting_sdk/
cp -r qt_libs demo/lib/zoom_meeting_sdk/
cp translation.json demo/lib/zoom_meeting_sdk/json/

# Create required symlink
cd demo/lib/zoom_meeting_sdk && ln -s libmeetingsdk.so libmeetingsdk.so.1
```

### 2. Initialize & Auth

```cpp
#include "zoom_sdk.h"

USING_ZOOM_SDK_NAMESPACE

// Initialize SDK
InitParam init_params;
init_params.strWebDomain = "https://zoom.us";
init_params.enableLogByDefault = true;
init_params.rawdataOpts.audioRawDataMemoryMode = ZoomSDKRawDataMemoryModeHeap;
InitSDK(init_params);

// Authenticate with JWT
AuthContext auth_ctx;
auth_ctx.jwt_token = your_jwt_token;
CreateAuthService(&auth_service);
auth_service->SDKAuth(auth_ctx);
```

### 3. Join Meeting

```cpp
// In onAuthenticationReturn callback
void onAuthenticationReturn(AuthResult ret) {
    if (ret == AUTHRET_SUCCESS) {
        JoinParam join_param;
        join_param.userType = SDK_UT_WITHOUT_LOGIN;

        auto& params = join_param.param.withoutloginuserJoin;
        params.meetingNumber = 1234567890;
        params.userName = "Bot";
        params.psw = "password";
        params.isVideoOff = true;
        params.isAudioOff = false;

        meeting_service->Join(join_param);
    }
}
```

### 4. Access Raw Data

```cpp
// In onMeetingStatusChanged callback
void onMeetingStatusChanged(MeetingStatus status, int iResult) {
    if (status == MEETING_STATUS_INMEETING) {
        auto* record_ctrl = meeting_service->GetMeetingRecordingController();

        // Start raw recording (enables raw data access)
        if (record_ctrl->CanStartRawRecording() == SDKERR_SUCCESS) {
            record_ctrl->StartRawRecording();

            // Subscribe to audio
            auto* audio_helper = GetAudioRawdataHelper();
            audio_helper->subscribe(new MyAudioDelegate());

            // Subscribe to video
            IZoomSDKRenderer* video_renderer;
            createRenderer(&video_renderer, new MyVideoDelegate());
            video_renderer->setRawDataResolution(ZoomSDKResolution_720P);
            video_renderer->subscribe(user_id, RAW_DATA_TYPE_VIDEO);
        }
    }
}
```

## Critical Gotchas & Best Practices

### ⚠️ CRITICAL: PulseAudio for Docker/Headless

**The #1 issue for raw audio in Docker:**

Raw audio requires PulseAudio and a config file, even in headless environments.

**Solution**:
```bash
# Install PulseAudio
apt-get install -y pulseaudio pulseaudio-utils

# Create config file
mkdir -p ~/.config
cat > ~/.config/zoomus.conf << EOF
[General]
system.audio.type=default
EOF

# Start PulseAudio with virtual devices
pulseaudio --start --exit-idle-time=-1
pactl load-module module-null-sink sink_name=virtual_speaker
pactl load-module module-null-sink sink_name=virtual_mic
```

See: [references/linux-reference.md#pulseaudio-setup](references/linux-reference.md)

### Raw Recording Permission Required

Unlike Video SDK, Meeting SDK requires explicit permission to access raw data:

```cpp
// MUST call StartRawRecording() first
auto* record_ctrl = meeting_service->GetMeetingRecordingController();

SDKError can_record = record_ctrl->CanStartRawRecording();
if (can_record == SDKERR_SUCCESS) {
    record_ctrl->StartRawRecording();
    // NOW you can subscribe to audio/video
} else {
    // Need: host/co-host status OR recording token
}
```

**Ways to get permission**:
1. Bot is host/co-host
2. Host grants recording permission
3. Use `recording_token` parameter (get via [REST API](https://developers.zoom.us/docs/meeting-sdk/apis/#operation/meetingLocalRecordingJoinToken))
4. Use `app_privilege_token` (OBF) when joining

### GLib Main Loop Required

SDK callbacks execute via GLib event loop:

```cpp
#include <glib.h>

// Setup main loop
GMainLoop* loop = g_main_loop_new(NULL, FALSE);

// Add timeout for periodic tasks
g_timeout_add_seconds(10, check_meeting_status, NULL);

// Run loop (blocks until quit)
g_main_loop_run(loop);
```

**Without GLib loop**: Callbacks never fire, join hangs indefinitely.

### Heap Memory Mode Recommended

Always use heap mode for raw data to avoid stack overflow with large frames:

```cpp
init_params.rawdataOpts.videoRawDataMemoryMode = ZoomSDKRawDataMemoryModeHeap;
init_params.rawdataOpts.shareRawDataMemoryMode = ZoomSDKRawDataMemoryModeHeap;
init_params.rawdataOpts.audioRawDataMemoryMode = ZoomSDKRawDataMemoryModeHeap;
```

### Thread Safety

SDK callbacks execute on SDK threads:
- Don't perform heavy operations in callbacks
- Don't call `CleanUPSDK()` from within callbacks
- Use thread-safe queues for data passing
- Use mutexes for shared state

## Production Architectures

**See**: [concepts/high-level-scenarios.md#scenario-2](concepts/high-level-scenarios.md)

```
Join Meeting → StartRawRecording → Subscribe Audio+Video →
Write YUV+PCM → FFmpeg Merge → Upload to Storage
```

### AI Meeting Assistant

**See**: [concepts/high-level-scenarios.md#scenario-3](concepts/high-level-scenarios.md)

```
