Review question: I put the FFMETADATA1 code in ld-export-metadata, because it's a bit too complex (and magical) to be an LdDecodeMetaData method. Should the other two existing export modes be the same? Or should they all be in, say, library/tbc/export.cpp...? |

I'm not a big fan of duplicating functionality :) I also think a separate tool is the better approach to metadata export. I'd be happy if both export functions in the metadata library were removed and placed in the ld-export-metadata app locally. Then both functions can be removed from the library and ld-analyse as they will not be required. |
To start with, this provides a command-line interface to LdDecodeMetaData's existing CSV export methods.
Simon suggested that it'd be better to have this in the export tool.
You can feed the output of this into ffmpeg, to produce (for example) Matroska output with chapter markers. Stop codes are just listed as comments at the moment. This is a straight translation of my decode-vbi Python program.

This now moves all the export code into ld-export-metadata, and removes the ld-analyse GUI bits for it. |

This is a new command-line tool for converting information from the JSON file into formats that other tools can understand. At present, it can do:
I've tested FFMETADATA1 export against all the decoded discs I had around, and it seems to produce reasonable results for anything that has chapters.
Exporting CC subtitles as SRT would be a useful future extension.
