- sky-cam.conf: CAMERAS now includes east, north, south with staggered
SCHEDULE_SEASONS times (01:00, 01:30, 02:00); fullday schedules and
tuning removed
- install.sh: fullday service/timer generation removed entirely
- fullday-video.sh + systemd units: deleted
- montage-mvt.sh: post-build technical checks (duration drift, video/audio
stream presence) added; notification now includes check results and the
exact verify-mvt.sh command to run
- verify-mvt.sh: new interactive CLI for montage review — shows checks,
plays video, deletes source JPEG folders on approval, or re-runs montage
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
capture-watchdog.sh: long-running script that checks the newest JPEG mtime
in each camera's output directory every CAPTURE_STALE_SECS/3 seconds (min 5s).
Sends a stall notification via notify.sh if no new frame has arrived within
CAPTURE_STALE_SECS. Sends a recovery notification once new frames resume.
Only alerts if the camera was previously working (avoids false positives on
first start or overnight before the first frame of the day).
sky-cam.conf: CAPTURE_STALE_SECS=30 added next to CAPTURE_INTERVAL with a
note that it should be at least 2x the interval.
install.sh: generates sky-cam-watchdog-<cam>.service for every camera that
has a RTSP URL configured. The watchdog service starts after and alongside
the capture service, restarts on failure, and is enabled/started with the
same loop as the capture service.
README.md: note about watchdog and journalctl command for its logs.

Cameras are now named by direction (east, north, south, west) throughout
config defaults, examples, and documentation. The config key SUNRISE_CAM
is unchanged — it still means 'which camera faces east and gets the sunrise
job'. Only the camera instance name value changes from 'sunrise' to 'east'.
sky-cam.conf: CAMERAS=(east), SUNRISE_CAM=east, SCHEDULE_*_east,
example comments updated to show all four compass points.
README.md: all command examples updated (4-seasons.sh east, journalctl
sky-cam-capture-east, etc.) — phenomenon references ('sunrise window',
'sunrise time') left unchanged.
bootstrap.sh: example updated to show compass directions.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Previously sunrise-audio-capture.sh recorded the entire capture window
(70+ minutes) and daily_sunrise_video.sh sought to the right position with
a complex offset calculation.
Now: record floor(TARGET/2) seconds before sunrise and ceil(TARGET/2) after —
odd second goes to post-sunrise. The file is exactly SUNRISE_TARGET_SECS long
and already centred, so no offset is needed when mixing.
AUDIO_PRE_BUFFER_MIN removed — it was part of the old whole-window scheme
and is no longer meaningful.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sky-cam.conf:
- SCRIPT_DIR auto-detects from its own location via BASH_SOURCE — no manual
path entry needed after bootstrap; override still works via environment.
- BASE_DIR defaults to \$SCRIPT_DIR/data; MOVIES_DIR defaults to \$BASE_DIR/movies.
Override either to point at a drive/mount as before.
- SCHEDULE_SUNRISE changed to 03:00 — the script now waits internally until
the capture window closes before touching images, so the schedule just needs
to be early enough, not timed exactly to sunrise.
- Schedule section rewritten to explain what each job does and what day's data
it processes (SEASONS/FULLDAY always process yesterday).
- SUNRISE_PRE_MIN/POST_MIN comments explain the window and its relationship to
SUNRISE_TARGET_SECS.
- SUNRISE_OVERLAY_ENABLED=true added; set false to skip the timestamp entirely.
daily_sunrise_video.sh:
- After calculating the capture window, sleep until end_sec+30s if we fired
before the window finished — guarantees all images are present.
- DT (drawtext filter) is only built when SUNRISE_OVERLAY_ENABLED=true.
- Step 3b skips ffmpeg entirely when overlay is disabled, moving work_video
directly to final_video (faster, no re-encode).

sky-cam.conf now sources .env from the same directory at the bottom of the
file, so RTSP URLs, Mattermost tokens, and notification credentials can live
outside version control. Plaintext credential placeholders removed from conf.
install.sh generates .env.example on every run with the correct CAM_RTSP_*
variable names derived from the CAMERAS list, so users always know exactly
what to put in .env for their specific camera setup.
.gitignore: add .env and sunrise-sounds/ (downloaded audio library).
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
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.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
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
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Adds six CRF vars, AUDIO_BITRATE, and three MONTAGE_* overlay durations.
Values match previous hardcoded defaults so behavior is unchanged.
The same CRF appeared in several scripts but with intentionally different
values per purpose (28 for draft intermediates, 26 for polished output).
Each script's CRF is now its own variable in conf, so changing one never
silently changes another.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
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
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- sunrise_video.10s.sh: use $TIMEZONE (was hardcoded America/New_York),
$SUNRISE_PRE_MIN/$SUNRISE_POST_MIN for capture window, $SUNRISE_TARGET_SECS
for output duration (was wrong value 8 in a script named 10s)
- fullday-video.sh: remove hardcoded FULLDAY_FPS/RETENTION_DAYS; both now
come from sky-cam.conf
- 4-seasons.sh, montage-mvt.sh: export TIMEZONE after sourcing conf so
season_info.py subprocess picks it up via env rather than falling back
to its hardcoded America/New_York default
- sky-cam.conf: add SUNRISE_PRE_MIN, SUNRISE_POST_MIN, SUNRISE_TARGET_SECS,
FULLDAY_FPS, RETENTION_DAYS
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sunrise.py now reads LATITUDE, LONGITUDE, and TIMEZONE from sky-cam.conf
instead of hardcoded values, using the same pathlib-based pattern as
sunrise2mm.py. sky-cam.conf gains a comprehensive header with manual
systemd setup instructions and a full script map for future reference.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sky-cam.conf
- Add SCRIPT_DIR (install location) and CAM_NAME (camera/folder name)
- These are the only values that change when deploying to a new machine
install.sh (new)
- Sources sky-cam.conf, generates all systemd .service and .timer units
with correct ExecStart paths, then enables and starts the timers
- Run once after editing sky-cam.conf; run again if paths change
- Supports --system flag for system-wide install
All .sh scripts + sunrise2mm.py
- No hardcoded paths remain
- script_name=$(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
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
sky-cam.conf (new)
- Single file replaces mattermost_config.txt reference, notify_config.txt,
and the hardcoded BASE_DIR/MUSIC_DIR/TIMEZONE scattered across scripts
- Bash-sourceable and Python key=value readable (same format)
All .sh scripts
- source sky-cam.conf at startup; BASE_DIR / MUSIC_DIR from config
sunrise2mm.py
- Reads sky-cam.conf relative to script location; no hardcoded path
notify.sh
- Sources sky-cam.conf; Mattermost credentials come from there directly,
no separate mattermost_config.txt lookup needed
systemd/sky-cam-notify-failure@.service (new)
- Template unit called by OnFailure= in each service
- Sends notification via notify.sh when any sky-cam job fails
- All three .service units now have OnFailure=sky-cam-notify-failure@%n.service
Removed: notify_config.txt, sky-cam.crontab (superseded)
