MattJackson 8bbf630d82 Fix all PES pipeline audit findings (20 issues) 
Critical:
- C1: PES serialize validates track < 256 and data < 4GB
- C2: PES deserialize caps frame size at 256MB (OOM protection)
- C3: TsMuxer stuffing uses static buffer, no per-packet alloc
- C4: PES length uses unbounded (0x0000) for audio >65535 bytes
- C6: TsDemuxer validates AF length <= 183

Warning:
- W1: parse_timestamp validates marker bits, returns Option
- W2: PES header data_start clamped to data.len()
- W3: TsMuxer PTS conversion uses saturating_mul, rejects negative
- W4: AC3/DTS replace debug_assert with runtime bounds check
- W6: MKV block_vint handles 3-4 byte VINTs
- W7: meta.rs to_title() uses unwrap_or fallbacks instead of panic
- W8: MKV reader skips frames for non-existent tracks
- W9: DVD PTS uses higher-precision conversion (1e9/90000)
- FMKV read_header caps JSON at 10MB
- PAT section_len underflow guard

Suggestion:
- S2: TsMuxer uses static STUFF_FF buffer
- S3: HEVC parser single-pass NAL scan (was duplicated)
- S4: TsDemuxer caps remainder at one packet
- S5: PTS 90kHz→ns uses round-to-nearest

MattJackson 75dfd06a02 Fix all v4 audit findings (22 items) 
HIGH: ISO writer multi-extent for >4GB, end-to-end MKV mux test
MEDIUM: AACS cvalue bounds, UV offset, macOS discovery, VC-1 resolution
  from sequence header, HEVC profile flags from SPS, ISO CRC + reserve AVDP
LOW: PS AC3 sub-header, CSS crack first-match break, TrackUID unique,
  AC3 no-sync empty return, --all for iso://, --min warning, dead code removed

320 tests, all passing.

MattJackson ffa0eaba4d cargo fmt + clippy --fix: 104 format violations fixed, 8 clippy auto-fixes 2026-04-11 19:10:20 +00:00
MattJackson 515f2f6bc2 100% codec coverage + disc/ and aacs/ module refactors 
Codec coverage (DVD + BD + UHD):
- E-AC-3 (Dolby Digital Plus): bsid detection, frame size calc — 8 tests
- DTS-HD MA/HR: extension substream (0x64582025) detection — 8 tests
- LPCM: BD header skip, raw PCM extraction — 6 tests
- DVD VobSub subtitles: passthrough parser — 5 tests
- Dolby Vision: verified RPU NAL type 62 preserved in HEVC — 1 test

Module refactors:
- disc.rs → disc/mod.rs + bluray.rs + dvd.rs + encrypt.rs
- aacs/mod.rs (1661 lines) → mod.rs (21) + keydb.rs + keys.rs + decrypt.rs
- All public APIs preserved, all tests pass

270 tests total, 0 failures.

MattJackson ff5547363b Audit fixes + DVD support foundation (IFO, PS demux, MPEG-2, CSS crack) 
Audit fixes (14 critical, 22 warnings):
- UDF: bounds checks on all ICB/FID parsing from disc data
- SCSI Linux: saturating_sub on residual, CDB length guard, buffer size guard
- SCSI macOS: SCSITaskStatus u32 (was u8 — stack corruption)
- AACS: EC mod_inv returns infinity instead of panic, key reduced mod n
- AACS: do_handshake tries all host certs (was returning on first failure)
- H.264: bounds check on SPS < 4 bytes
- ContentReader: error on missing unit key (was zero-fill)
- KEYDB: flat redirect loop (was recursive), 100MB response limit, Windows HOME fallback
- ISO writer: AVDP extent order, partition length, allocation cap
- Network: removed TCP_NODELAY on bulk stream
- MKV: guard on u64::MAX seek
- disc.rs: saturating_sub on extent offset, simplified dead region code
- cargo fmt (610 violations), cargo clippy --fix (55 auto-fixes)

DVD support (new files):
- src/ifo.rs — IFO parser (VIDEO_TS.IFO, VTS_XX_0.IFO, PGC chains, cells, streams) — 13 tests
- src/mux/ps.rs — MPEG-2 Program Stream demuxer (pack headers, PES, private stream 1) — 12 tests
- src/mux/codec/mpeg2.rs — MPEG-2 video parser (sequence headers, I-frame detection) — 15 tests
- src/css/crack.rs — split-attack algorithm (LFSR cipher needs verification — test ignored)

226 tests total (was 186), 1 ignored (CSS crack needs cipher verification).

MattJackson 8c2f3898b8 Add IOStream trait and stream-based I/O architecture 
Introduce IOStream trait for uniform read/write across disc, file,
network, and null streams. Rename Title→DiscTitle, add stream URL
resolver, split old stream.rs into focused modules (m2ts, mkvstream,
network, disc, null, resolve, meta).

MattJackson 48b212c9d2 Add MKV muxer and event system 
- Add event.rs: structured event system for progress reporting
- Add mux/: MKV muxer pipeline (EBML writer, TS demuxer, stream assembly)
  - Codec parsers: H.264, HEVC, AC-3, DTS, TrueHD, PGS, VC-1
  - Lookahead buffer for codec private data extraction
  - Direct m2ts-to-MKV streaming without intermediate files
