# Camera Skill ## Available Cameras | Camera | Index | Position | Best For | |--------|-------|----------|----------| | **Brio 100** | 0 | On external monitor, facing user directly | Front view, face shots | | **FaceTime HD** | 1 | MacBook on right side, angled toward user | Side/profile view | ## Capture Commands Use `-loglevel error` to suppress ffmpeg spam. Always warm up for 5s (camera needs exposure adjustment). ### Brio (front view) ```bash ffmpeg -loglevel error -f avfoundation -framerate 30 -i "0" -t 5 -y /tmp/brio_warmup.mp4 && \ ffmpeg -loglevel error -sseof -0.5 -i /tmp/brio_warmup.mp4 -frames:v 1 -update 1 -y /tmp/brio.jpg ``` ### FaceTime (side view) **Must use `-pixel_format nv12`** to avoid buffer errors. ```bash ffmpeg -loglevel error -f avfoundation -pixel_format nv12 -framerate 30 -i "1" -t 5 -y /tmp/facetime_warmup.mp4 && \ ffmpeg -loglevel error -sseof -0.5 -i /tmp/facetime_warmup.mp4 -frames:v 1 -update 1 -y /tmp/facetime.jpg ``` ### Both cameras (parallel) Run both commands simultaneously for multi-angle shots. ## Output - Photos saved to `/tmp/brio.jpg` and `/tmp/facetime.jpg` - Warmup videos in `/tmp/*_warmup.mp4` (can be deleted) - Photos are ~80-100KB each ## Gotchas - Close Photo Booth or other camera apps first (can conflict) - FaceTime camera REQUIRES `-pixel_format nv12` or it fails with buffer errors - 5s warmup is necessary for proper exposure
