- verify-mvt.sh: remove dead first _info= line (used MVT_START before defined); fix JPEG size loop to accumulate bytes correctly and display human-readable total; show size in delete confirmation - montage-mvt.sh: grep -c uses || echo 0 instead of || true to be unambiguous about the no-match value under set -e - capture.sh, capture-watchdog.sh: require camera name arg, remove silent SUNRISE_CAM fallback - migrate-seasons.sh: require --cam arg, error if missing - README.md, sky-cam.conf: remove stale fullday-video.sh references; README pipeline diagram updated to show verify-mvt.sh https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ

# capture.sh <cam-name> — continuous JPEG frame capture from a camera's RTSP
|
|
# stream. Replaces MotionEye or any NVR for sky-cam's timelapse pipeline.
|
|
# Pure ffmpeg — no NVR software required.
|
|
#
|
|
# Run as a long-running systemd service (Type=simple), one per camera.
|
|
# install.sh generates sky-cam-capture-<cam>.service automatically when
|
|
# CAM_RTSP_<cam> is set in sky-cam.conf.

#
|
|
# Writes: BASE_DIR/<cam>/YYYY-MM-DD/HH-MM-SS.jpg
|
|
# Restarts ffmpeg at midnight so images land in the correct date directory.
|

# On camera disconnect, waits 30 s then reconnects automatically.
