|
## 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
