archives: Making a file with chapters

Unlike OGM, MKV can import an MPEG2 vob, if you don't want to rip/re-encode.

mkvmerge --chapters <file> -o movie.mkv dvd.vob

av_metadata_set(&s→metadata, “title”, matroska→title);

av_metadata_set is in metadata.c

libmpdemux/demux_lavf.c

    if(avfc->title    [0]) demux_info_add(demuxer, "title"    , avfc->title    );

 compat_tab[] = {

    { "author",          SIZE_OFFSET(author)    },
    { "copyright",       SIZE_OFFSET(copyright) },
    { "comment",         SIZE_OFFSET(comment)   },
    { "album",           SIZE_OFFSET(album)     },
    { "year",            SIZE_OFFSET(year)      },
    { "track",           SIZE_OFFSET(track)     },

    { "artist",          SIZE_OFFSET(author)    },

    { "tracknumber",     SIZE_OFFSET(track)     },
    { "part_number",     SIZE_OFFSET(track)     },
};

Looks like these are the only ones actually supported:

    FILL_METADATA_STR(ctx, title);
    FILL_METADATA_STR(ctx, author);
    FILL_METADATA_STR(ctx, copyright);
    FILL_METADATA_STR(ctx, comment);
    FILL_METADATA_STR(ctx, album);
    FILL_METADATA_INT(ctx, year);
    FILL_METADATA_INT(ctx, track);
    FILL_METADATA_STR(ctx, genre);
