Traces <clinit> bytecode to find ldc/putstatic pairs that map
enum field names to display name strings. Pattern: new X, dup,
ldc "English", invokespecial X.<init>, putstatic X.a.
Proven on Dune UHD JAR: aw.a="English", aw.b="French", etc.
Next: trace mapping class (ISO code → enum field) to complete the chain.
Labels like eng_MLP_ now match to the correct stream by checking language
and codec hint against the stream's properties. Fixes Barbie where labels
were swapped (TrueHD label was on DD stream). TextField format (Civil War)
still uses index matching.
TrackLabel now carries language + codec_hint for structured matching.
- Extract all class strings once, try format parsers in chain
- Format 1: TextField,Audio{N} (A24/Lionsgate) — fixes Civil War
- Format 2: eng_MLP_ label strings (Warner UHD) — Barbie, Dune
- Format 3: playlist-only (MAIN_FEATURE etc.)
- Simplified TrackLabel to just description + raw
- 5 unit tests for both formats
- Tested on 12 disc captures: Civil War now gets 3 audio + 2 sub labels
Known issues: Barbie labels swapped, Dune returns 0 labels (different format?)
apply_jar_labels() matches JAR audio/subtitle labels to streams by
position and sets AudioStream.label. Apps read labels directly from
streams instead of doing their own JAR matching.
Each stream type has only its relevant fields. No more HDR on audio
or channels on video. Added SubtitleStream.forced field (TODO: parse).
Removed display helpers from lib (belongs in CLI).
- Size from source_packet_count * 192 (matches libbluray approach)
- metadata_sector_ranges() uses actual metadata partition size from ICB
instead of arbitrary +256 margin (fixes Top Gun missing CLIPINF)
- Store metadata_sectors in UdfFs
- Fix CLPI CPI bit-packed field parsing (partial, EP map still needs work)
- Disc.volume_id: UDF Volume ID from PVD (always present)
- Disc.meta_title: from META/DL/bdmt_eng.xml (falls back to other languages)
- Disc.format: UHD/BluRay/DVD detected from video codec
- Disc.capacity_bytes, Disc.layers
- Disc.jar_labels: extracted from BDMV/JAR
- Fixed MPLS STN parsing: 16-byte header (was 8), proper stream entry offsets
- Streams now include: HDR, color space, Dolby Vision EL, secondary audio/video
- parse_dstring() for UDF d-string fields
- wait_ready() polls TEST UNIT READY before unlock
Tested on 12 disc captures — all return correct titles, streams, format.
Walk UDF tree to discover sector ranges for all metadata files
(MPLS, CLPI, JAR, AACS certs, etc). Skips STREAM/, BACKUP/,
DUPLICATE/, MKB_RO.inf, ContentHash. Exposes partition_start()
and metadata_start() getters. Used by bdemu smart capture.
- Error codes as public constants (E_DEVICE_NOT_FOUND etc.) — single source of truth
- SCSI opcodes as named constants (SCSI_READ_10, SCSI_REPORT_KEY, etc.)
- AACS key class constant, MKB format constant
- No magic numbers in CDB construction
- docs/disc-to-rip.md — end-to-end flow from disc insert to decrypted content
- Links all module docs together as a starting point
- Removed specific drive counts (was "206 bundled")
- Removed version-specific install instructions
- Added Disc::scan() + ContentReader as primary API example
- Added AACS section explaining transparent decryption
- Added docs/ link for technical documentation
- Added E7xxx AACS error range
- Evergreen — no dates or counts that need manual maintenance
File data extents are in the physical partition (partition_start + lba),
not the metadata partition. ICBs (directory/file entries) are in metadata,
but the data they point to is in physical. This one-line fix makes all
MPLS playlists readable — previously only 1/18 had correct MPLS magic.
Tested on Civil War UHD: 18 playlists, main movie at 00400.mpls (57min, 6 clips).
- AacsState now exposes: version (1/2), bus_encryption, mkb_version,
disc_hash, key_source (KeyDb/KeyDbDerived/ProcessingKey/DeviceKey),
vuk, unit_keys, read_data_key, volume_id
- All keys are public — apps that contribute to KEYDB ecosystem can
read VUK, unit keys, Volume ID, disc hash for database submission
- resolve_keys reports which path succeeded (key_source 1-4)
- Cleaned up resolve_keys with shared builder to reduce duplication
- Device key subset-difference tree: aesg3 key derivation, v_mask calc,
tree traversal from device key to processing key to media key
- MKB SCSI read: REPORT DISC STRUCTURE 0x83 with multi-pack support
- resolve_keys now has 4 paths:
1. disc hash → KEYDB → VUK
2. KEYDB media key + VID → VUK
3. MKB + processing keys → media key → VUK
4. MKB + device keys → processing key → media key → VUK
- setup_aacs reads MKB from drive (not just from file)
- AACS 2.0 detection: drive cert type 0x11 detected, falls back to
AACS 1.0 handshake (P-256 crypto path prepared but not yet built)
- STN table parsing in mpls.rs: video format/rate, audio format/rate/lang,
subtitle lang, coding type — all streamed into Disc title streams
- 31 tests passing
Parses device keys, processing keys, host cert, per-disc VUKs.
Full KEYDB.cfg (60MB, 180K entries) parsed in 1.85 seconds.
All test discs found with VUKs.
Next: disc hash computation, title key decryption, content decryption.
Prevents indefinite hangs on encrypted/unreadable sectors.
Some discs put MPLS/CLPI/JAR data in AACS-encrypted regions
that block reads without proper AACS authentication.
Scans BDMV/JAR/*.jar class files for track label patterns:
eng_MLP_ → TrueHD, eng_ADES_US_ → Descriptive Audio (US)
dan_PGStream4 → Danish subtitles
Solves the "3x AC-3 English" problem — we identify Descriptive Audio, commentary, compatibility tracks.
Future: set MKV "visual impaired" flag automatically during mux.
Local only — needs more disc samples to validate before publishing.

- Linux SG_IO behind #[cfg(target_os = "linux")]
- macOS IOKit and Windows SPTI stubs with TODO
- drive.rs uses scsi::open() — no platform-specific imports
- Compiles on macOS (returns "platform not yet supported")
- Removed supported field — if we have a profile, try unlock
- Removed ReadinessStatus, DriveMatch, flashable detection
- N0 and NM firmware both unlockable (library is agnostic)
- README: full API docs, chipset table, error codes, example output
Features:
- Open drive identification via SPC-4 INQUIRY + MMC-6 GET CONFIGURATION
