ld export metadata

ld-export-metadata

This application reads an ld-decode JSON metadata file, typically as produced by ld-process-vbi, and exports information in standard formats that other tools can read. At present, it can export:

• Per-frame signal quality information from the VITS test signals, as CSV
• Per-frame LaserDisc VBI control signals, as CSV
• LaserDisc navigation information, as Audacity labels
• LaserDisc navigation information, as FFMETADATA1 (which FFmpeg can use to add chapter navigation to a video file)
• Closed Captions, as SCC format (which tools like ttconv can read)
