The real sky-cam repo's capture.sh already replaces MotionEye/any NVR itself (plain ffmpeg RTSP frame-grab) - it and daily_sunrise_video.sh's optional audio capture are the only places that touch a camera's RTSP URL directly. Every other script (4-seasons, montage-mvt, year-end-join, moon-track, moon-phase-monthly) only reads JPEGs/audio already on disk. So the entire motionEye->Frigate transition is pointing CAM_RTSP_<cam> at Frigate's go2rtc restream (rtsp://<frigate-host>:8554/<cam>) instead of the camera directly - no upstream script changes needed. Replaces the previous frigate-retime.sh/export-API approach, which solved a problem (matching an arbitrary recording length to music duration) that sky-cam's own 4-seasons.sh/montage-mvt.sh already handle via JPEG frame counts.

# services/sky-cam-frigate.sh — Automated sky / timelapse camera scripts
|
|
# (sky-cam), configured to source frames from Frigate instead of a camera's
|
|
# RTSP stream directly.
|
|
# Part of the modular post-install system (sourced by setup.sh).
|
|
#
|
|
# Can also be run standalone on any machine:
|
|
# sudo bash sky-cam-frigate.sh
|
|
# (Docker must already be installed when run standalone; Frigate should
|
|
# already be configured with the cameras you want — see services/frigate.sh.)
|
|
#
|
|
# NON-DOCKER module — this is the exact same upstream sky-cam project as
|
|
# services/sky-cam.sh (same clone, same scripts, same systemd timers). The
|
|
# only difference is what CAM_RTSP_<cam> points to in .env:
|
|
#
|
|
# sky-cam.sh CAM_RTSP_<cam> = the camera's own RTSP URL directly
|
|
# sky-cam-frigate.sh CAM_RTSP_<cam> = Frigate's go2rtc restream for that
|
|
# camera (rtsp://<frigate-host>:8554/<cam>)
|
|
#
|
|
# Why this is the only change needed: sky-cam's capture.sh is itself a
|
|
# from-scratch RTSP frame-grabber that "replaces MotionEye or any NVR" (its
|
|
# own header comment) — it pulls one JPEG frame every CAPTURE_INTERVAL
|
|
# seconds from whatever CAM_RTSP_<cam> points to and writes it to
|
|
# BASE_DIR/<cam>/YYYY-MM-DD/HH-MM-SS.jpg. Every other script in the pipeline
|
|
# (4-seasons.sh, montage-mvt.sh, year-end-join.sh, moon-track.sh,
|
|
# moon-phase-monthly.sh, daily_sunrise_video.sh) only ever reads JPEGs/audio
|
|
# already sitting in BASE_DIR — none of them know or care whether the camera
|
|
# was reached directly or through Frigate's restream. Pointing capture.sh at
|
|
# Frigate's go2rtc endpoint instead of the camera means Frigate stays the
|
|
# single RTSP client against the camera (recording + detection), and sky-cam
|
|
# becomes a second, cheap consumer of Frigate's already-open stream — no
|
|
# upstream sky-cam script edits required.
