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
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.
- scsi::open() returns Box<dyn ScsiTransport> on any platform
- 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")
Features:
- Open drive identification via SPC-4 INQUIRY + MMC-6 GET CONFIGURATION
- 141 supported drives with bundled profiles
- MT1959 platform: unlock, calibrate, raw sector reads
- DriveSpeed enum: BD1x-BD12x, DVD1x-DVD16x
- Field names follow SPC-4 §6.4.2 and MMC-6 §5.3.10 standards
- No proprietary fingerprints — open matching by SCSI fields
- Zero config: profiles compiled into binary
Tested on real hardware: HL-DT-ST BD-RE BU40N 1.03
