## What it does

This skill brings together guidance for the Zoom Video SDK on Windows, including a session-join pattern, API references, callback details, and examples for video rendering and raw audio or video data. The SDK also supports screen sharing, cloud recording, live streaming, chat, and real-time transcription.

The material includes build troubleshooting and examples for C++ and C#. C++ development requires Windows 10 version 1903 or later, or Windows 11, Visual Studio 2019 or 2022, and Windows SDK 10.0.19041.0 or later. Your application must process the Windows message queue; otherwise SDK callbacks will not fire. C# applications require .NET Framework 4.8 or later.

## Install

### Codex (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill windows -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/windows/SKILL.md` — For all projects use ~/.agents/skills/

### Claude Code

1. **Skills CLI (Vercel)**
```bash
npx skills add openai/plugins --skill windows -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/windows/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/windows/

### Cursor

**Manually: put the files in place**
- File: `.cursor/skills/windows/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install openai/plugins windows
```

2. **Manually: put the files in place**
- File: `.github/skills/windows/SKILL.md`

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/openai/plugins --path plugins/zoom/skills/video-sdk/windows
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/windows/SKILL.md` — The legacy .windsurf/skills/ path still works

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/openai/plugins/tree/HEAD/plugins/zoom/skills/video-sdk/windows/SKILL.md

## When to use it
- join a Zoom Video SDK session from a Windows application
- capture or inject raw audio and video data
- add screen sharing to a Windows application
- troubleshoot SDK build errors or callbacks

## Example prompts
- Show me how to join a Zoom Video SDK session from a C++ Windows app.
- Explain how to capture YUV420 video frames with the SDK.
- Help me diagnose why Zoom Video SDK callbacks are not firing.

## SDK Overview

The Zoom Video SDK for Windows is a C++ library that provides:
- **Session Management**: Join/leave video SDK sessions
- **Raw Data Access**: Capture raw audio/video frames (YUV420, PCM)
- **Raw Data Injection**: Send custom audio/video into sessions
- **Screen Sharing**: Share screens or inject custom share sources
- **Cloud Recording**: Record sessions to Zoom cloud
- **Live Streaming**: Stream to RTMP endpoints (YouTube, etc.)
- **Chat & Commands**: In-session messaging and command channels
- **Live Transcription**: Real-time speech-to-text
- **Subsessions**: Breakout room support
- **Whiteboard**: Collaborative whiteboard features
- **Annotations**: Screen share annotations
- **C# Integration**: C++/CLI wrapper for .NET applications
