Platform trait is no longer publicly exported. External code uses
DriveSession only — cannot call unlock, load_firmware, calibrate directly.
- Platform trait: pub(crate) with 3 methods only
- All handlers are private methods on Mt1959
- DriveStatus moved to mt1959 internal struct
- init() has guard: no re-init if already ready
- set_read_speed() has guard: no-op if not calibrated
- Removed open_unlocked() — open() is the only entry
- Removed Platform and DriveStatus from public exports
Prevents: out-of-sequence SCSI commands, double-init, wrong firmware writes.
- Removed open_unlocked() — open() is the only entry
- Removed redundant init() call from open_title()
- init() called once in open(), handles everything
- Each function does one thing: open→init→scan→read
DriveProfile now has every field traced from firmware:
- drive_signature, unlock_init_value, unlock_response_size_minus_init
- ld_microcode (base64, ~1888B firmware payload)
- hardware_register_a_cdb, hardware_register_b_cdb (10B pre-built CDBs)
- drive_nominal_speed_cdb (12B calibration speed)
- speed_zone_table (28B), speed_calc_table (25B)
drive.rs simplified:
- open() calls init() instead of unlock()
- init() is the ONLY entry point — handles full dispatch sequence internally
- Removed read_config, read_register, maintain_speed, read_sectors from public API
- Added set_read_speed() for per-zone speed during content reads
- disc.rs updated to call init() instead of unlock()
Compiles clean, all tests pass.
Back to basics: open, unlock, SET CD SPEED max, read.
Remove all calibration probes, register reads, maintain_speed calls.
This is closest to the build that hit 17 MB/s earlier.
Also: drive discovery moved to libfreemkv (find_drive, resolve_device),
AACS via UDF only, clean pipeline, sg device support.
- Fixed: extents were relative to m2ts file, not absolute disc LBAs
- Fixed: u16 truncation of remaining sector count (13M → 36!)
- Added: UdfFs::file_start_lba() for m2ts LBA lookup
- Added: DriveSession::read_content() with 30s timeout for bulk reads
- Added: SET CD SPEED 0xFFFF on title open
- Added: adaptive batch reading (96→48→3 on error, ramp back up)
- Rip working end-to-end: scan → AACS → decrypt → write
Architecture:
- Each BD-J format in own file: paramount.rs, criterion.rs, pixelogic.rs, ctrm.rs
- Standard interface: detect() → bool, parse() → Option<Vec<StreamLabel>>
- PARSERS array in mod.rs — drop in a new parser with one line
- Shared vocab.rs for BD spec codec names only (MLP→TrueHD, AC3→Dolby Digital)
- All other label data passes through raw from disc — no guessing
Changes:
- New: paramount.rs (playlists.xml — Paramount/onQ format)
- Renamed: bluray_project.rs → pixelogic.rs
- Renamed: stream_properties.rs → criterion.rs
- Merged: language_streams.rs + menu_base.rs → ctrm.rs
- Removed: jar module (superseded by labels), dead apply functions
- Added: DriveSession::eject() with PREVENT ALLOW MEDIUM REMOVAL
- Added: DiscRegion enum (Free/BluRay/Dvd)
- Fixed: capture sector ranges now include all files (only skip STREAM/)
- Renamed: StreamLabel.region → variant (not a BD spec field)
- 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.
- 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
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.
- 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
