- DriveSession::open() no longer requires profile match — works on any optical drive
- init()/probe_disc() return error gracefully for unknown drives
- find_drives() returns all optical drives (PDT 0x05), not just profile-matched
- has_profile() check for callers
- AACS 2.0: handshake wired into resolve_aacs() — real VID + read_data_key
- DriveId: added raw_gc_010c field for GET_CONFIG 010C response bytes
- Split AacsError { detail } into 13 specific error variants (AacsCertShort,
AacsAgidAlloc, AacsCertRejected, etc.) with unique error codes E7001-E7012
- Split DiscError { detail } into 7 specific variants (DiscRead, MplsParse,
ClpiParse, UdfNotFound, DiscNoTitles, DiscTitleRange, DiscNoExtents)
- Add WriteError (E5001), KeydbLoad (E8005), MuxLookahead (E9000), MuxWrite (E9001)
- Add OpenDisc API for single-call open+scan+rip workflow
- Remove all English text from error Display impl (code-only output)
- Normalize doc comments to use -- instead of em dash for ASCII consistency
- 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
When MPLS STN table parsing drifts (disc-specific alignment issue),
a PGS subtitle entry (coding_type 0x90/0x91) can appear in the audio
stream section. Previously this showed as garbled "ng PGS 5.1" audio.
Fix: guard in stream builder checks if audio-typed streams have
subtitle codecs and reclassifies them as subtitles.
Also: unknown stream types now filtered out (filter_map) instead of
creating fake Video entries that showed as "?" in output.
Tested on V for Vendetta BD — "ng PGS 5.1" gone, clean output.
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.
BD drives reject the MediaTek unlock command (sense 0x05).
Unlock is only needed for UHD raw access. Standard BD reads
work with standard READ(10) without vendor unlock.
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)
labels::apply(session, udf, titles) does everything internally.
Disc::scan() is one line: crate::labels::apply().
No intermediate variables, no fallback logic in disc.rs.
App reads disc.titles[].streams — labels already applied if
disc had config files, empty otherwise. MPLS data always there.
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.
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.
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.
- 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
- 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
