Per-camera capture interval:
CAPTURE_INTERVAL_<cam> in sky-cam.conf overrides the global value for
a specific camera. capture.sh and 4-seasons.sh both respect it.
Example: south at 30s saves storage; north at 5s gives smoother motion.
4-seasons.sh one-frame bug fix:
Same root cause as the sunrise scripts — concat list had no 'duration'
entries, collapsing all JPEG frames to timestamp 0. Fixed by writing
'duration INTERVAL' per frame. Added fps=25 to the speed-adjust step
so the VFR source resamples to a standard frame rate.
ambient-record.sh (new):
Continuous AAC recorder for natural sounds (birds, rain, wind).
Saves AMBIENT_CHUNK_SECS chunks to AMBIENT_DIR/<cam>/YYYY-MM-DD/HH-MM-SS.m4a.
Reconnects automatically on stream failure. Rolling retention via
AMBIENT_RETENTION_DAYS. Enabled by setting AMBIENT_ENABLED=true and
listing cameras in AMBIENT_CAMS in sky-cam.conf, then re-running install.sh.
