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- Removed: jar module (superseded by labels), dead apply functions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)
- 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.
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).
