CAM_RTSP_<cam> is set in .env, not sky-cam.conf, but capture.sh was
only sourcing sky-cam.conf — causing the service to fail with "not set"
even after credentials were added to .env.

Root cause: the concat list had no 'duration' entries, so all JPEG
frames collapsed to timestamp 0 and only one frame survived encoding.
Fix: add 'duration CAPTURE_INTERVAL' per entry in both scripts.
Also add fps=25 to the speed-adjust step so the VFR source is resampled
to a standard frame rate — without this, players see ~6fps and may drop
frames to reach the declared rate.
daily_sunrise_video.sh --test [MINUTES]:
Skips sunrise.py lookup and capture-window wait. Uses the last MINUTES
minutes of captured frames (default 2). Overlay shows the mid-point
frame's timestamp. Audio grabbed live from RTSP immediately.
Output: <date>-daily-sunrise-test.mp4 — no notifications or upload.
Usage: ./daily_sunrise_video.sh east --test 2

- fontcolor: white → yellow (both scripts)
- y position: (h-th)/2 → h-th-18 (vertically centered → lower-right corner)
- test-sunrise.sh: reverted to reading last 60 frames from capture directory
(~10 minutes at 10s interval) instead of live RTSP capture
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Overlay fix (both scripts):
Switch from text='...\n...' to drawtext's textfile= option. Writing
each character on its own line eliminates the \n escape ambiguity in
ffmpeg's filter-string single-quote parser, which was causing 'n' to
appear literally instead of as a line break.
test-sunrise.sh redesign:
Now captures NUM_FRAMES fresh RTSP frames (120s at default interval)
at run time instead of reading pre-existing frames from the capture
directory. The RTSP URL must be set in .env — the script fails early
with a clear message if it is not.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- Overlay text was showing characters run together (e.g. '1n2n') because
inside ffmpeg single-quoted filter text, \n is consumed as just 'n'.
Fix: use \\\\n in bash double-quotes which stores \\n in the variable,
which ffmpeg then parses as \n, which drawtext renders as a newline.
Applied to both test-sunrise.sh (MID_VERT) and daily_sunrise_video.sh
(SR_VERT, replacing the awk one-liner with the same bash approach).
- test-sunrise.sh concat list was missing per-frame duration entries,
causing 12 frames to encode as 0.48s (25fps default) and then slow
down instead of compress. Fixed by writing 'duration INTERVAL' per
frame so 12 frames × 10s = 120s raw → 12× compression to 10s.
- Removed 2>/dev/null from audio ffmpeg call in test-sunrise.sh so
capture failures are visible for diagnosis.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Runs the same 4-step pipeline as daily_sunrise_video.sh but uses the
most recent ~2 minutes of captured frames instead of the sunrise window,
grabs live RTSP audio for the audio mix step, and accepts an arbitrary
output path — so it can be run at any time of day to verify the full
pipeline (speed-adjust, audio mix, vertical time overlay) without
waiting for tomorrow's sunrise.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
capture.sh creates the per-day subdirectory at runtime, but BASE_DIR/<cam>
and MOVIES_DIR/<cam> need to exist first. Create them during install so the
capture service works immediately on first start without needing a separate
manual mkdir step.

The shell version had to pass the password through a shell variable into
a Python subprocess, which is fragile for special characters.
The Python version uses getpass.getpass() which reads directly from the
terminal at the Python level — no shell variable, no quoting issues, no
risk of special characters being mishandled.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Prompts for a password without echoing, URL-encodes it via Python's
urllib.parse.quote, and prints the result with a ready-to-paste .env
snippet. Password is passed via environment variable to avoid any
shell quoting or injection issues — never written to disk or network.

- Set XDG_RUNTIME_DIR before systemctl --user calls so daemon-reload
and enable --now work when run outside a login session (e.g. via SSH
or sudo)
- Run loginctl enable-linger so user services start at boot without a
login session
- Update .env.example to use single quotes around RTSP URLs and
document URL-encoding for special characters in passwords
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Older sky-cam.conf versions may not define these. Fall back to the
canonical defaults so make-finals.sh works without requiring the user
to update their local conf.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Allows processing a single movement without waiting for the full backup
scan, e.g.:
./make-finals.sh ~/drives/data2-main --cam north --season Autumn --mvt 1
Filters are applied as soon as the relevant variable is known (cam before
calling season_info.py, season/mvt after) so skipped files cost almost
nothing.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
The previous check used || true which masked ffprobe's non-zero exit
code. For files with a missing/partial moov atom ffprobe can print a
duration estimate then exit non-zero — the || true let that through.
Now use || raw_dur="" to honour the exit code, and add a second probe
for an actual video stream codec so files that report a duration but
have no decodable stream are also caught.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Short adagio movements (Summer Mvt 2 at 107s, Winter Mvt 2 at 132s, etc.)
compress each day to only 3-5 seconds of screen time at 1×. Looping the
music N times multiplies the per-day target duration proportionally so the
footage is less aggressively sped up and more watchable.
- sky-cam.conf: add MONTAGE_MUSIC_LOOPS and per-movement overrides
(Summer Mvt2=3×, Winter Mvt2=3×, Autumn Mvt2=2×, Summer Mvt3=2×, Spring Mvt2=2×)
- 4-seasons.sh: multiply target_per_clip by loops
- montage-mvt.sh: compute effective_duration, use -stream_loop for audio,
fix fade_out_start, -t, and post-build duration check
- make-finals.sh: multiply target by loops
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Check ffprobe output before encoding — empty/N/A duration means the
file is corrupt or truncated; skip with a clear message rather than
passing a bad input to ffmpeg.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Scans all *-temp.mp4 files under a backup root regardless of directory
structure, infers camera name from path, uses season_info.py for correct
movement sizing, writes finals to MOVIES_DIR. Handles messy nested paths
(south/south/, movies/south/, etc.) and deduplicates via EXISTS check.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Restructure find loop to iterate known CAMERAS+sunrise in the main shell
so cam_name is visible in the while body. Previously the for loop ran in
a process substitution subshell, making cam_name unavailable and causing
top-level year dirs (e.g. 2026/) to be treated as camera names.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Moves Season/MvtN mp4 files from flat camera dirs into
astro-YEAR/<cam>/Season/MvtN/ using season_info.py for correct
year assignment. Handles cross-year mixing in old backup structure.
Dry-run support; never deletes files.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
Re-processes *-temp.mp4 files from a backup location using season_info.py
to compute the correct target duration per clip (music_duration / DAYS_IN_MVT),
producing properly-sized *-final.mp4 files without touching the backup source.
Skips finals that already exist. Fixes drift caused by old pipeline sizing clips
to the wrong movement structure.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- sky-cam.conf: add ENCODE_PRESET=slow (applied to all encodes);
split CRF_MONTAGE (intermediates, H.264) from CRF_MONTAGE_FINAL=22
(archive montage, H.265); add SUNRISE_RETENTION_DAYS=10; improve
CAPTURE_INTERVAL comment with storage/density table
- montage-mvt.sh: steps 1+2 use preset; step 3 final switches to
libx265 + CRF_MONTAGE_FINAL + -tag:v hvc1 for broad compatibility
- 4-seasons.sh: both encode steps use ENCODE_PRESET
- daily_sunrise_video.sh: all encode steps use ENCODE_PRESET; rolling
retention deletes sunrise videos older than SUNRISE_RETENTION_DAYS
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- 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
No script defaults to SUNRISE_CAM (east) for the seasons pipeline.
Every direction is treated equally — camera name is a required arg,
not an optional override.
- 4-seasons.sh: $1 required, exits with usage if missing
- montage-mvt.sh: arg order changed to <cam> [date]; $1 required
- year-end-join.sh: $2 (cam) required
- verify-mvt.sh: $4 (cam) required
- migrate-seasons.sh: example commands updated to new arg order
- README.md: montage-mvt.sh examples updated
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- 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
--cam NAME overrides SUNRISE_CAM so the script can be used for any
camera (e.g. north). Summer is now included in the find targets so
any ASTRO_YEAR=2025 Summer clips (Summer 2026) are also migrated.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
The old pattern *Mvt*3* matched .mp3 in every MP3 filename, so sort|head-1
always picked track 01 (Mvt1). Fix by finding all files for the season
then filtering with grep -iE "Mvt[^0-9]*N[^0-9]", which requires the
movement number to be surrounded by non-digit characters (space, dot,
underscore) and cannot match digits embedded in .mp3 or track prefixes.
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
All *-final.mp4 clips are valid footage regardless of what speed factor
the old script used — montage-mvt.sh re-adjusts the full concatenated
video to match music duration anyway, so per-clip speed is irrelevant.
Move every ASTRO_YEAR=2025 clip to the correct new movement directory
based on its date. Spring Mvt1 now gets all 30 clips (Mar 21–Apr 19).
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
- Filter to ASTRO_YEAR=2025 (Winter 2025-26 onward); skip Autumn 2025 and earlier
- Move files instead of creating symlinks
- Quarantine clips matching Day<N>of92 (Spring clips from broken script with
wrong 92-day movement total) to quarantine-old-scripts/ for review + deletion
- Preserve clips with Dayof92 (no day number, old legacy format) — these are
migrated normally since montage-mvt.sh re-adjusts speed regardless
- Summary shows delete commands for temp files and quarantine folder
https://claude.ai/code/session_01C4jbd3waXG3eKZYbGUjLUQ
migrate-seasons.sh uses season_info.py to re-classify every old
*-final.mp4 clip by its YYYY-MM-DD filename prefix, placing a symlink
in the correct new-system directory regardless of how the old system
labelled movements. Handles the boundary mismatches between old and
new movement splits automatically.
Coverage after migration (based on available clips):
Spring 2026 Mvt1 30/31 days (missing Day 1 only — excellent)
Winter Mvt1 ~18/29 days
Winter Mvt2 ~24/29 days
Winter Mvt3 ~20/31 days
Autumn Mvt1 ~24/30 days
Autumn Mvt3 ~18/30 days
Autumn Mvt2 absent — year-end join will not fire for 2024 cycle
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.
