Camera

Capture photos from MacBook webcams. Use when user asks to take a photo, picture, snapshot, or see them. Two cameras available - Brio (front-facing on monitor) and FaceTime (side angle from MacBook).

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)

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.

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
