Removes dependency on MotionEye or any NVR software. Everything is now
CLI/ffmpeg configured entirely from sky-cam.conf.
capture.sh
Long-running systemd service (one per camera) that pulls frames from the
camera's RTSP stream at CAPTURE_INTERVAL seconds, writing HH-MM-SS.jpg
into BASE_DIR/<cam>/YYYY-MM-DD/. Restarts at midnight for the new date
directory; auto-reconnects on camera disconnect.
sunrise-audio-capture.sh
One-shot service triggered at 03:00. Waits until (sunrise minus
SUNRISE_PRE_MIN minus AUDIO_PRE_BUFFER_MIN), then records the RTSP audio
stream for the full sunrise window. Output deleted after mixing.
daily_sunrise_video.sh
Step 3 now mixes in sunrise-audio.m4a when AUDIO_ENABLED=true and the
file exists. Audio is centred on actual sunrise time at natural speed
while the video plays as the sped-up timelapse. Uses filter_complex
when audio is present (can't combine -vf with -filter_complex).
install.sh
Generates sky-cam-capture-<cam>.service for each camera with CAM_RTSP_<cam>
set, and sky-cam-audio-capture.{service,timer} when AUDIO_ENABLED=true.
sky-cam.conf
New settings: CAM_RTSP_<cam>, CAPTURE_INTERVAL, AUDIO_ENABLED,
AUDIO_PRE_BUFFER_MIN, CAPTURE_AUDIO_BITRATE.

daily_sunrise_video.sh:
- Fixed: was using undefined \$MOVIES_DIR (now \$BASE_DIR/movies)
- Fixed: sunrise_overlay.py was called but never existed — would fail daily
- Fixed: speed-adjust step had no explicit codec (-c:v libx264 missing)
- New: sunrise time overlaid as stacked vertical characters on the right
side using ffmpeg drawtext — no Python/Pillow dependency
- New: upload removed from script; now triggered by systemd OnSuccess=
- Combines speed-adjust and overlay into one ffmpeg pass (was two)
- SUNRISE_OVERLAY_OPACITY from conf controls transparency
install.sh:
- sky-cam-sunrise.service gains OnSuccess=sky-cam-sunrise-upload.service
so upload only runs when video creation succeeds, with separate log
- New sky-cam-sunrise-upload.service runs sunrise2mm.py
sunrise2mm.py: add shebang + chmod +x so systemd ExecStart= calls it directly
sky-cam.conf: add SUNRISE_OVERLAY_OPACITY=0.45

sky-cam.conf:
- CAMERAS array replaces single CAM_NAME; add a name, add its schedules,
re-run install.sh — no script editing needed
- SCHEDULE_SUNRISE, SCHEDULE_SEASONS_<cam>, SCHEDULE_FULLDAY_<cam> replace
hardcoded times in install.sh
- Notification options commented out (uncomment to enable)
- Lat/lon set to mid-Atlantic (25.0, -38.0) as neutral placeholder
install.sh:
- Loops over CAMERAS to generate per-camera sky-cam-seasons-<cam> and
sky-cam-fullday-<cam> timers with schedules from conf
- Sunrise timer remains a single sky-cam-sunrise unit (SUNRISE_CAM only)
fullday-video.sh, 4-seasons.sh, montage-mvt.sh, year-end-join.sh:
- Each accepts camera name as an argument (systemd passes it via ExecStart)
and falls back to conf default when run manually without an arg
- Camera name propagates through the full call chain:
4-seasons → montage-mvt → year-end-join

sky-cam.conf
- Add SCRIPT_DIR (install location) and CAM_NAME (camera/folder name)
- These are the only values that change when deploying to a new machine
install.sh (new)
- Sources sky-cam.conf, generates all systemd .service and .timer units
with correct ExecStart paths, then enables and starts the timers
- Run once after editing sky-cam.conf; run again if paths change
- Supports --system flag for system-wide install
All .sh scripts + sunrise2mm.py
- No hardcoded paths remain
- script_name=$(basename ...) derivation replaced by $CAM_NAME from conf
- sunrise_video.10s.sh now sources sky-cam.conf for BASE_DIR, CAM_NAME,
and SCRIPT_DIR (replaces all /home/motion/... references)
- sunrise2mm.py builds video path from BASE_DIR + CAM_NAME in conf
systemd/ template files kept as reference but no longer need editing
