- 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

# test-sunrise.sh — smoke-test the sunrise pipeline using recent captured frames.
|
|
#
|
|
# Uses the last ~10 minutes of JPEGs from SUNRISE_CAM then runs the same
|
|
# 4-step pipeline as daily_sunrise_video.sh:
|
|
# 1. raw video from captured JPEGs
|
|
# 2. speed-adjust to SUNRISE_TARGET_SECS
|
|
# 3. grab SUNRISE_TARGET_SECS of live RTSP audio
|
|
# 4. mix audio + burn vertical time overlay
|
|
#
|
|
# Usage:
|
|
# ./test-sunrise.sh [output_path]
|
|
# ./test-sunrise.sh ~/drives/data2-main/test3.mp4
