Matt Jackson 8843833ea7 v0.11.15: lint cleanup — fmt + clippy clean 2026-04-21 18:52:55 +00:00
Matt Jackson 1bea8eb650 v0.11.7: TrueHD parser rewrite — 12-bit length, AC-3 skip, cross-PES buffering 2026-04-19 01:36:56 +00:00
Matt Jackson ca3914d537 Fix TrueHD: strip BD-TS access unit header before muxing to MKV 2026-04-18 19:26:14 +00:00
MattJackson 911d260695 Buffer audio parsers across PES boundaries 
- 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
 2026-04-16 19:02:23 +00:00
MattJackson 59d4eb8854 Fix AC3 parser: buffer across PES boundaries, proper frame sizing 
- 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

MattJackson 597f512eca Fix MPEG-2 PS demuxer: codec parsers, sequence header extraction, descramble 
- Route DVD PS packets through codec parsers (was bypassing them)
- Extract MPEG-2 sequence header with quantizer matrices for MKV codec_private
- Calculate exact sequence header size from intra/non-intra matrix flags
- Capture sequence extension (B5) from subsequent PES packets
- Revert TAB1 permutation in descramble (XOR-only is correct)
- Fix CSS roundtrip tests for new descramble behavior

MattJackson e0f40583c4 Fix cargo fmt formatting 2026-04-15 22:32:53 +00:00
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 ff6004a567 Unified Stream trait: read() and write() on one type 
Stream trait: read() returns PesFrame, write() accepts PesFrame.
A stream is a stream — you read from it or write to it.
No separate Input/Output traits.

API: libfreemkv::input(url) and libfreemkv::output(url, title, codecs)
Returns Box<dyn Stream>.

- 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
