- Updated launch_with_signal.py with PEP 723 metadata for uv compatibility - Added day/night mode presets with command-line arguments - Implemented proper rollover-only file saving via Python/PIL callbacks - Removed multifilesink from pipeline (was saving every frame incorrectly) - Added funny auto-generated output directory names (e.g., fuzzy-photon) - Updated rollover_example.py to follow same pattern with uv support - Updated rollover_example.c to demonstrate signal detection without file saving - Updated launch_with_capture.ps1 to remove incorrect multifilesink usage - All scripts now save files ONLY on rollover events, not every frame - Pipeline simplified: camera -> linescan -> display (files saved in callback)

# Linescan Pipeline Example - PowerShell GStreamer Launch
|
|
#
|
|
# This script demonstrates a GStreamer linescan pipeline using gst-launch-1.0.
|
|
# NOTE: This saves EVERY frame using multifilesink, not just on rollover.
|
|
#
|
|
# For proper rollover-only saving, use the Python scripts instead:
|
|
# - launch_with_signal.py (full-featured with camera)
|
|
# - rollover_example.py (simple demo)
|
|
#
|
|
# This script is kept as a reference for the pipeline structure.
|
|
#
|
|
# Prerequisites:
|
|
# 1. Build the plugins: .\build.ps1
|
|
# 2. Run from workspace root: c:\dev\gst-plugins-vision
|
|
#
|
|
# Usage:
|
|
# .\gst\linescan\launch_with_capture.ps1
|
|
#
|
|
# Pipeline:
|
|
# idsueyesrc -> intervalometer -> videocrop -> queue -> linescan -> videoconvert -> autovideosink
|
|
#
|
|
# WARNING: This example saves every output frame, not just on rollover!
|
|
# Use Python scripts for rollover-based capture.
|
