norihiro/obs-face-tracker — reverse-engineered prompt

Build me an OBS Studio plugin that can detect a person’s face in a video source, keep tracking it, and automatically crop or zoom the frame so the face stays centered. I want it to work both as its own Face Tracker source and as a filter you can add to an existing source. Please also include the experimental PTZ camera control filter that follows the tracked face, as long as it matches what this project already supports.

Make it feel usable inside OBS, with the basic properties hooked up so someone can pick a source and adjust tracking behavior. Set up whatever face detection and landmark model files are needed under the data folder, and make sure the install step puts them in the right place. I’d like the project to build cleanly and be reasonably ready for Windows, Linux, and macOS, with notes for any platform specific setup.

If anything is unclear, check the current OBS and related docs online and wire it up in the simplest working way.
