# Error: "unknown signal name: rollover"
# - Cause: Linescan plugin not found or not properly registered with GStreamer

# 1. Build plugins: .\build.ps1
# 2. Ensure GST_PLUGIN_PATH environment variable includes build output directory
# 3. Check plugin was built: look for linescan.dll in build directory
# 4. Test plugin availability: gst-inspect-1.0 linescan
