- For
- Raspberry Pi owners who want local HDMI capture
- Worth noticing
- The setup uses Python, FastAPI, ffmpeg, and one HTML file, with no Docker, database, or JavaScript build step.
Field notes
The setup instructions start with Raspberry Pi OS, ffmpeg, and Python 3, then install the project from GitHub into a virtual environment. The page says saved clips are stitched without re-encoding and that the buffer restarts if HDMI drops. It also warns that the interface has no login: anyone on the same network can open it, and the Pi should not be exposed to the internet.
