ipma-carta

Visual Studio Code extension that loads the IPMA weather forecast map sequence, builds an MP4 animation, and displays it directly in a VS Code webview.

Requirements

• ffpem/ffmpeg installed and available in PATH.

It is required on your machine and is not an npm dependency.

What It Does

• Adds command IPMA Weather Map (ipma-carta.showWeatherMap).
• Downloads IPMA weather map frames.
• Creates weather_output.mp4 with ffmpeg.
• Reuses a fresh local cache.
• Opens video in a VS Code webview.

Usage

1. Open Command Palette.
2. Run IPMA Weather Map.
3. Wait for the first generation (may take longer on first run).
4. The animation opens in a VS Code panel.

If webview playback fails, use the fallback button to open the video externally.

Output location:

• ~/.ipma-carta-images/ipma-cartas/weather_output.mp4

Troubleshooting

• ffmpeg is not installed or not in PATH: install ffmpeg and restart VS Code.
• No frames downloaded: IPMA structure/network may have changed; retry later and check logs.
• Browser launch issues: run npx playwright install chromium.
