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.
