Recompress an image to JPEG at a target width to shrink it for vision models. |
video_to_gif |
Convert a video clip to an animated GIF (two-pass palette optimization). |
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 frameHow it works
- One shared
FFmpeginstance 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.
