daily_sunrise_video.sh:
- Insert continuous ambient recording extract as 2nd fallback (after today's
scheduled sunrise audio, before live RTSP). Finds the chunk file in
AUDIO_DIR/<cam>/<date>/ whose start time is the latest one at or before
sunrise, then ffmpeg-copies SUNRISE_TARGET_SECS centred on sunrise_sec.
- Renumber remaining fallbacks: live RTSP → 3rd, yesterday → 4th, library → 5th.
sunrise-audio-capture.sh:
- Fix: retention find pipeline could exit non-zero (directory not yet created
or permission error) and with set -euo pipefail cause the service to report
status=1/FAILURE even after a successful capture. Guard with [ -d ] and
add || true so a retention failure never masks a successful recording.

The retention block ended with `[ test ] && echo`, which under `set -e`
returns exit 1 when `deleted` is 0 — the normal case on most days. As
the script's last command, that bash exit propagated to systemd, which
marked the unit failed and fired the OnFailure ntfy even though the
audio file was written successfully.
Add `|| true` and an explicit `exit 0` so a no-op retention pass is
treated as success.
New AUDIO_DIR variable (like BASE_DIR/MOVIES_DIR) is the root for all
audio recordings. Set in .env to put audio on a separate drive.
Directory layout:
AUDIO_DIR/<cam>/YYYY-MM-DD/HH-MM-SS.m4a — ambient recordings
AUDIO_DIR/sunrise/<cam>/YYYY-MM-DD/sunrise-audio.m4a — sunrise clips
sky-cam.conf:
- Add AUDIO_DIR="${AUDIO_DIR:-$BASE_DIR/audio}" in storage section
- Remove AMBIENT_DIR (replaced by AUDIO_DIR)
- Add SUNRISE_AUDIO_RETENTION_DAYS=7 (sunrise clips kept separately from ambient)
- Add per-camera ambient retention examples:
AMBIENT_RETENTION_DAYS_south=60 (keep bird recordings longer)
ambient-record.sh:
- Use AUDIO_DIR instead of AMBIENT_DIR
- Per-camera retention: AMBIENT_RETENTION_DAYS_<cam> overrides global default
sunrise-audio-capture.sh:
- Save clips to AUDIO_DIR/sunrise/<cam>/<date>/sunrise-audio.m4a
- Rolling retention of sunrise clips (SUNRISE_AUDIO_RETENTION_DAYS)
daily_sunrise_video.sh:
- Look for cam_audio in new AUDIO_DIR/sunrise path first, fall back to
old BASE_DIR path so existing recordings keep working
install.sh:
- Pre-create AUDIO_DIR/<cam> and AUDIO_DIR/sunrise/<SUNRISE_CAM> dirs
- Add AUDIO_DIR to .env.example storage section

montage-mvt.sh, year-end-join.sh: CAM_NAME fallback referenced undefined
\$CAM_NAME — crashes under set -euo pipefail on manual runs without args.
Fixed to fall back to \$SUNRISE_CAM (same fix applied earlier to other scripts).
notify.sh: Mattermost notification guard only checked MM_NOTIFY_CHANNEL_ID,
not mattermost_url or access_token. If those are unset, curl would send a
malformed request silently. Added guards for all three required values.
install.sh: seasons/fullday service units had literal \n in After=/Wants=
lines because bash does not interpret \n in heredoc variable expansions.
Changed to \$'...' syntax so actual newlines are written, making valid
systemd unit files. Also: audio capture timer now uses \$SCHEDULE_SUNRISE
instead of hardcoded 03:00, keeping it in sync if the user changes the
schedule.
sunrise-audio-capture.sh: record_start_sec could theoretically go negative
(sunrise very early + large SUNRISE_TARGET_SECS). Added floor-at-zero guard.
daily_sunrise_video.sh: added comment explaining why audio_offset is always 0.
README.md: fix CAM_RTSP_sunrise example to CAM_RTSP_east.

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
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.
