src/labels/ with 4 parsers tried in order: 1. language_streams.txt (Warner CTRM CSV) 2. menu_base.prop (Warner CTRM properties) 3. streamproperties.xml + playbackconfig.xml (Criterion XML) 4. bluray_project.bin (Pixelogic binary tokens) Disc::scan() calls labels::extract() → apply_disc_labels(). If no disc files found, streams keep MPLS data as-is. No JAR fallback — disc files or nothing. Covers 4/8 discs with JARs (Dunkirk UHD, V for Vendetta BD, Being There, Barbie). Remaining 3 (Civil War, Dune, V for Vendetta UHD) have no disc config files.

//! Stream label extraction from BD-J disc files.
|
|
//!
|
|
//! Searches the disc UDF filesystem for known config files that contain
|
|
//! stream labels (language, purpose, codec, forced flags). Four formats
|
|
//! supported, tried in order:
|
|
//!
|
|
//! 1. `language_streams.txt` — Warner CTRM CSV format
|
|
//! 2. `menu_base.prop` — Warner CTRM properties format
|
|
//! 3. `streamproperties.xml` + `playbackconfig.xml` — Criterion XML format
|
|
//! 4. `bluray_project.bin` — Pixelogic binary format
