camera_preview

Preview local camera devices directly through OpenCV.

s6 camera_preview

By default the command opens device indices 1 and 3, displays them in one window with per-camera FPS overlays, and exits when you press q.

Use --device to override the list:

s6 camera_preview --device 1 3

The current defaults are:

• --device 1 3

• --width 1280

• --height 960

• --fps 50

• --max-seq-skew 0

Use --flip-stage to apply one or more videoflip stages to every preview camera.
