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.jpgand/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 nv12or it fails with buffer errors - 5s warmup is necessary for proper exposure
