dsh-video-tools 🎬

Browser-local audio/video tools for DeepSeek Harness (DSH), powered by FFmpeg.wasm.

No uploads, no servers — every operation runs in your browser via WebAssembly.

Install

dsh plugin add @piedpiper911/dsh-video-tools

Tools

Example: give a vision model frames from a local video

1. upload the video → workspace
2. video_frames { input: "demo.mp4", count: 4 }
3. describe what you see in each frame

How it works

• One shared FFmpeg instance is lazily loaded on first use and reused for the
  whole session — the ~30 MB core downloads exactly once.
• All I/O happens in FFmpeg's in-memory virtual filesystem; nothing touches disk.
• Tool arguments are validated with the DSH schema DSL (defineTool), so the
  model only ever sees well-formed inputs.
