Matt Jackson 66e474c338 v0.11.5: MKV container fixes — timestamps, frame rate, HDR, chapters, disposition 2026-04-18 16:29:21 +00:00

MattJackson 75066744d1 Move codec_privates onto DiscTitle, eliminate duplicate methods 
Design fix: codec_privates are now a field on DiscTitle, not a separate
parameter passed through the pipeline. This eliminates the root cause of
the network codec_private bug (forgot to pass the separate param).

API changes:
- output() takes (url, &DiscTitle) — no separate codec_privates param
- MkvOutputStream::create, M2tsOutputStream::create, NetworkOutputStream::connect
  all read codec_privates from title.codec_privates
- M2tsMeta::from_title() takes only &DiscTitle — reads privates from title
- Deleted from_title_with_privates (was the wrong-name duplicate)
- Merged read_header + read_header_from_stream into one read_header(impl Read)
- Deleted finish(self) from TsMuxer, keep only finish(&mut self)

Rule: ONE public method per action. No _with_X, _from_Y, _ref variants.

MattJackson 5287dd65ce 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 55d1aff2b3 Fix M2TS/MKV roundtrip: codec_private in FMKV header, Annex B conversion 
Bug 1: M2TS roundtrip dropped frames — TsMuxer converts length-prefixed
NALs to Annex B, prepends VPS/SPS/PPS from HEVCDecoderConfigurationRecord.

Bug 2: MKV remux lost codec_private — MkvStream.codec_private() now returns
data from EBML header.

FMKV header carries codec_private (base64) per video stream for lossless
M2TS roundtrip.

MattJackson 1a9956cea0 Fix all clippy warnings: dead code, match patterns, type complexity, docs 
- Remove unused pes_buf field from M2tsStream and unused TS_PACKET/BD_TS_PACKET constants
- Replace match-with-single-pattern with if let (3 instances in drive/mod.rs)
- Replace match-can-be-? with ? operator for scsi::open call
- Add type aliases PesSetup and MkvHeaderResult to reduce type complexity
- Collapse identical if/else branches in tsmux.rs build_pes_header
- Use RangeInclusive::contains instead of manual range checks
- Make WriteSeek trait pub (was pub(crate) but leaked through pub fn)
- Remove empty line after doc comment in disc.rs
- Fix doc list item indentation in scsi/linux.rs (12 instances)

MattJackson 323d04b7b7 100% PES pipeline — all streams produce/consume PES frames 
- TsMuxer: PES frames → BD-TS packets (new, reverse of TsDemuxer)
- M2tsOutputStream: PES → TsMuxer → file
- NetworkOutputStream: PES → TsMuxer → TCP
- StdioOutputStream: PES frames → stdout
- NullOutputStream: discard
- MkvOutputStream: PES → MKV mux
- All outputs via open_pes_output()
- All inputs via open_pes_input() (ISO, disc)
- No byte-level fallback — everything is PES
