Fix trailing sectors dropped at extent boundaries when sector_count % 3 != 0.
Add verify_title stop support via progress callback returning bool.
Add O_CLOEXEC on all SCSI fd opens to prevent leak to child processes.
Fix SCSI sense descriptor format detection (0x72/0x73 vs 0x70/0x71).
Replace blocking ioctl(SG_IO) with the sg driver's async interface.
Commands are submitted via write(), waited on via poll() with a hard
wall-clock timeout, and completed via read(). If poll() times out,
the fd is abandoned and a fresh one opened — the kernel can no longer
hold us hostage during USB error recovery.
- write() submits command, returns immediately
- poll() enforces exact timeout (EINTR-safe with deadline tracking)
- read() retrieves result + copies data to caller's buffer
- On timeout: old fd closed in background thread, new fd opened
- No SG_FLAG_DIRECT_IO — kernel buffers for safe timeout abandonment
- Store device_path for fd reopen after timeout
- Drop guards fd=-1 (abandoned fd)
Use UDF file_extents() to read actual allocation descriptors instead
of assuming m2ts files are contiguous from file_start_lba. Dual-layer
UHD discs split large files across 70+ extents (~1 GB each) — the old
code created one extent from packet count which only covered the first
chunk, causing silent truncation at ~37%.
Also changed fill_extents() to return io::Result<bool> so read errors
propagate instead of being silently treated as EOF.
A stream is a stream. DiscStream::new() takes reader + title + keys +
batch + format — same pattern as every other stream constructor.
Deleted: open_drive(), open_iso(), from_reader() — these were helper
functions that chained multiple operations. Library provides primitives,
callers decide the sequence.
Removed disc:// case from input() — callers use Drive::open() +
Disc::scan() + DiscStream::new() directly for disc sources.
- DTS: buffer with core sync detection + frame size from header
- TrueHD: buffer with unit length field parsing
- Same pattern as AC3 fix: incomplete frames held for next PES
- When PES boundaries align (normal case), buffering is a no-op
- Add state to Ac3Parser (was stateless, split frames at PES boundaries)
- Buffer leftover bytes from incomplete frames for next PES packet
- Calculate exact AC3 frame size from fscod/frmsizecod table
- Calculate EAC3 frame size from frmsiz field
- Skip invalid frame sizes (0 or >8192)
- Eliminates all AC3 decode errors on BD and UHD output
- DVD PS path now calls parser.parse() like BD-TS path does
- MPEG-2 sequence headers extracted for codec_private
- Keyframe detection from parser instead of always-true
- Fix CSS roundtrip tests: descramble uses TAB1 permutation, not pure XOR
- Implement complete CSS key chain: bus auth → disc key → title key
- Add 31 player keys for disc key decryption
- Read disc key via READ DVD STRUCTURE format 0x02
- Read title key via REPORT KEY format 0x04
- Fix CryptKey round 1: use original scratch for term, not modified tmp1
- Fix decrypt_key: use TAB5 for LFSR1 output, TAB4 for LFSR0^invert
- Fix descramble_sector: use TAB5 for LFSR1, TAB4 for LFSR0 (no invert),
and apply TAB1 permutation to ciphertext before XOR
- Fix title key bus XOR: forward order (bus_key[i]), not reversed
- Two-session auth: disc key and title key need separate AGID sessions
- Fix crack_key: scan across extents for scrambled sectors
- Fix TsDemuxer: dynamic PID table size for DVD PIDs
- Set max read speed after scan for DVD riplock removal
- Disc::copy() hardcoded batch=64 sectors, exceeding BU40N's 60-sector
hw limit. Now accepts batch_sectors param, defaults to 60.
- IFO PGC: playback time at offset 0x04 not 0x02, cell time at cell+4
- DiscStream: set demuxer from content_format (TS for BD, PS for DVD)
- Flush TS/PS demuxers at EOF to avoid losing last PES frame
- M2tsStream: flush demuxer at EOF
- StdioStream: FMKV metadata header for roundtrip compatibility
