Triage of a 10-lens code audit of the 3D branch. Fixes for real defects;
rejected three spec false-positives that matched the ISO/IEC 14496-15
§7.6.2 record verbatim.
Robustness / correctness:
- Never panic when a title's only video is the MVC dependent view: the
base is now the first NON-dependent video, so a dependent-only title
sets up no merge (muxed as an ordinary track) instead of hitting an
`expect` on the skipped track slot.
- Drop a per-frame BlockAdditional (BlockAddID=2) when the track declared
no mvcC mapping (dependent params not captured before the header) — a
plain block keeps the file conforming instead of an orphaned add.
- A non-keyframe MVC base frame always carries a ReferenceBlock (fall back
to a 0 offset in the pre-first-keyframe corner) so it is never mistaken
for a seek point.
- Reference the last keyframe on the PRIMARY video track only, so a
secondary video track's keyframe can't become a cross-track reference.
- dep_by_pts overflow: bound BEFORE inserting so the just-arrived
dependent survives the drift-clear; count a displaced duplicate-PTS
dependent as an orphan instead of losing it silently.
API / docs:
- Fold write_frame_with_additional into write_frame(..., Option<&[u8]>)
per the "no foo_with_X" convention.
- Fix mvc_params doc (StereoMode is intentionally not emitted); remove a
stale PAT/PMT comment describing an approach that was never taken.
Tests: MVCDecoderConfigurationRecord over-length guards; write_int minimal
two's-complement widths; BlockGroup/BlockAdditions/BlockAdditional +
ReferenceBlock emission; additional dropped without a mapping; h264 MVC
passthrough keeps param sets in-band; extract_mvc_params no-panic on
truncated/empty input; pairing window + dep-overflow edges; no-panic on a
dependent-only title.
Fold the MVC dependent (right-eye) view into the base H.264 track as a
per-frame BlockAdditional under an mvcC BlockAdditionMapping, so a 3D
title produces one MVC video track instead of two independent H.264
tracks.
- h264: MVC-passthrough parser mode keeps the dependent view's subset
SPS/PPS in-band, so each emitted frame is a self-contained dependent
access unit for a BlockAdditional
- resolve: route the dependent stream through the passthrough parser
- mkvstream: detect the dependent view, pair it to the base frame by
PTS (bounded FIFO), attach it as a BlockAdditional (BlockAddID=2),
and skip building its own track; build the mvcC
MVCDecoderConfigurationRecord from the captured subset SPS/PPS and set
it on the base track at activation
- mkv: emit the mvcC BlockAdditionMapping and BlockGroup/BlockAdditions,
with a ReferenceBlock on non-keyframe base frames
- ebml: add BlockAdditions/BlockMore/BlockAdditional/BlockAddID/
BlockAddIDValue/ReferenceBlock elements and a signed-int writer
Verified against a Blu-ray 3D ISO: ffprobe shows a single MVC track,
the mvcC mapping is present, ~144k BlockAdditionals carry the dependent
view (8.7 GB), and the base view decodes cleanly with no regression.
MVCDecoderConfigurationRecord follows ISO/IEC 14496-15 7.6.2; StereoMode
is intentionally omitted (no enum value describes MVC-in-BlockAdditional;
the mvcC mapping is the primary 3D signal per RFC 9559).
Surgical fixes (each with a regression test that fails without the change):
mux/mkv.rs, mux/demux_sink.rs: drive the clip-boundary timeline epoch
off the resolved PRIMARY VIDEO track, not the literal stream index 0.
An M2TS/PMT title can list an audio ES before video, so streams[0] may
be audio; a non-video epoch driver ratchets the frontier and inflates
the timeline. mkv cluster-opening falls back to track 0 for audio-only
titles so they still open clusters.
mux/codec/ac3.rs: correct ACMOD_CHANNELS — acmod=5 (3/1) is 4 channels,
not 3 (was undercounting a 3/1 stream); fix the A/52 Table 5.8 doc.
disc/mod.rs: HDMV coding_type 0x91 (Interactive Graphics / menus) no
longer maps to PGS subtitle — it falls through to Unknown so the PMT/STN
walker drops it instead of surfacing a bogus subtitle track.
mux/videomap.rs + mux/mkv.rs: FVI colour now mirrors the MKV muxer's CICP
precedence (measured CICP authoritative; HDR-driven PQ/HLG transfer
override) via a shared cicp_for_video helper, so the two sinks can't
disagree (HDR10 BT.2020 no longer emits SDR transfer 14).
mux/mkvstream.rs: saturating_add on cluster_ts + rel_ts so an adversarial
CLUSTER_TIMESTAMP near i64::MAX can't overflow/panic before the existing
saturating_mul.
mux/timeline.rs: tighten the tail-straggler clamp so a normal new-epoch
non-video frame leading the sparse video frontier by >3s is not demoted
into the previous clip's epoch.
mux/m2ts_mux/mod.rs: re-stamp PCR per video TS packet (mid-PES), not only
at PES boundaries, so a large UHD I-frame can't open a multi-second PCR
gap; modular 33-bit PTS rebasing so a real 90 kHz clock wrap is not
collapsed to PTS 0 (pre-base frames still floor to 0).
io/byte_prefetcher.rs, sector/prefetched.rs: wrap the producer feed loop
in catch_unwind and emit a typed error sentinel on panic, so a mid-stream
producer panic is not read as a clean EOF at the demux boundary (which
would silently truncate the mux).
mux/codec/h264.rs: extend HIGH_PROFILES to the full ISO/IEC 14496-15 set
that mandates the avcC chroma/bit-depth extension (adds 244 et al.).
Doc/comment accuracy: css/mod.rs (50000 sectors, not scrambled-sectors),
aacs/decrypt.rs (decrypt_unit already-clear path), ifo.rs (TT_SRPT at
0xC4), css/lfsr.rs (LFSR0 24-bit; TAB1-then-XOR cipher; real scramble-flag
predicate), disc/read_error.rs (for_sweep does bounded transient retries).
Skipped: keydb.rs SSRF guard (low/latent, no live caller) — a hard
loopback block breaks an existing behavioral test that exercises the
header-EOF path over a loopback server; a clean fix needs a resolver test
seam beyond this surgical pass. The sibling keydb_fetch.rs comment fix is
out of scope (freemkv crate).
Parse the two HDR10 HEVC SEI messages and emit the corresponding
Matroska Colour metadata, only when actually present in the bitstream
(SDR / no-SEI tracks omit it; nothing is fabricated).
Parse (Rec. ITU-T H.265 Annex D):
- Mastering Display Colour Volume SEI, payloadType 137 (D.2.28):
display_primaries_x/y[3] (SEI order G,B,R), white_point_x/y
(0.00002 units), max/min_display_mastering_luminance (0.0001 cd/m²).
- Content Light Level Info SEI, payloadType 144 (D.2.35):
MaxCLL / MaxFALL (cd/m² integers).
HevcParser::scan_sei walks the sei_rbsp ff-extension payloadType/
payloadSize coding and de-emulates (00 00 03) before reading, reusing
the existing strip_emulation_prevention helper. Both SEI are required
before any metadata is surfaced; SEI NALs still pass through unchanged.
Carry: the measured Hdr10Metadata rides PictureInfo (the same per-coded-
picture seam FieldOrder uses), flowing through from_codec_frame onto
PesFrame.coding to the deferred-muxer activate path, where
apply_coding_to_track stamps it on the video track before the header is
written. Set only when both SEI were seen.
Emit (RFC 9559 / Matroska): new Colour children in ebml.rs
(MasteringMetadata 0x55D0, Primary R/G/B + WhitePoint chromaticity
0x55D1..0x55D8, Luminance max/min 0x55D9/0x55DA, MaxCLL 0x55BC,
MaxFALL 0x55BD). write_hdr10 converts chromaticity SEI int × 0.00002 →
Matroska float, luminance SEI int × 0.0001 → cd/m² float; MaxCLL/MaxFALL
are uints verbatim. SEI primary index 0/1/2 (G/B/R) mapped to the
Matroska R/G/B element layout. Emitted only when hdr10 is present.
Tests: SEI parse with exact raw values, requires-both-SEI, SDR omission,
and emulation-prevention stripping (hevc.rs); muxer emit with exact unit
scaling + SDR omission of MasteringMetadata/MaxCLL/MaxFALL (mkv.rs);
apply_coding_to_track HDR10 plumbing (mkvstream.rs).
Carry per-picture truth and byte-exact source provenance THROUGH the stream so
the muxer (and the upcoming video index) read MEASURED facts instead of
assuming them. Honest data in, honest data out.
- codec/coding.rs: codec-agnostic PictureInfo (CodingType / FieldOrder + the
accessors field_order/coding_type/nb_fields/progressive/keyframe). Each codec
folds its raw signals in; consumers use only accessors, never branch on codec.
- mpeg2: builds PictureInfo from the picture coding extension and carries it +
SourcePos (source_marks, parallel to pts_marks) on every emitted frame.
- pes / codec::Frame: additive `coding` + `source`, forwarded through the
highway; None for audio/subtitle and the network/stdio deserialize hop.
- mkvstream: DEFER muxer construction until the first coded picture, set the
video track's FieldOrder from the MEASURED value, THEN write the header —
right the first time, no guess, no seek-back. An interlaced track that arrives
with no measured order is LOGGED loudly and left UNDETERMINED, never faked.
- mkv: MkvTrack::video no longer guesses TFF (a bitstream property the scan
cannot know is UNDETERMINED at build). Removed VideoStream::top_field_first
(the dead scan-time guess) crate-wide.
- Tests: parser population (every PictureInfo facet + per-PES source carry) and
mux-stream consumption (measured -> correct; missing -> UNDETERMINED, not
faked). Two obsolete tests updated only after confirming (their own comments)
they existed to enforce the deleted hardcoded-TFF.
- FieldOrder now derives from the bitstream's measured top_field_first
(Some(true)→TFF, Some(false)→BFF) instead of hardcoding TFF for all
interlaced content; falls back to TFF when unmeasured. Adds
VideoStream::top_field_first; DVD/BD scan sets None with a precise
TODO(spec) for parser→title plumbing.
- CICP (matrix/transfer/primaries/range) now prefers measured CICP from
the bitstream (VideoStream::measured_cicp) over the coarse ColorSpace
enum, so the container stops assuming a colour space the stream may
contradict. Enum remains the fallback.
- VobSub S_VOBSUB CodecPrivate now emits a `size: WxH` line ahead of the
palette per the .idx format so players place/scale subs correctly.
- SeekHead: when zero cues are written, the CUES Seek entry is Voided
instead of leaving a dangling pointer to the Cues offset (now Tags/EOF).
- AC-3 Channels back-patch offset is captured from the writer instead of
the hardcoded chan_elem_pos+2 (decoupled from the VINT width choice).
- Hoisted inline CICP codes and the dvcC fourcc to named constants citing
ITU-T H.273 / RFC 9559; fixed the stale FieldOrder comment.
- DefaultDuration vs pulldown: precise TODO(spec) left (needs the same
parser→title channel as top_field_first).
Tests: BFF-from-measured-flag, measured-CICP-overrides-enum, VobSub size:
line present/omitted, zero-cue SeekHead Void. precommit (1.86) green.
Three Silence-of-the-Lambs (R2 PAL SD-DVD) follow-ups for rc.5.2.
SUB-TASK 1 — Windows Explorer showed 12.5 fps (half) for the 576i25 track.
Root cause: the DefaultDecodedFieldDuration (20 ms field) element rc.5.1
added to "fix" Windows fps did the opposite. With FlagInterlaced=1 +
DefaultDuration=40 ms + DefaultDecodedFieldDuration=20 ms, Explorer halved
to 12.5 fps and MediaInfo flipped to VFR. MakeMKV's correct rip omits the
field-duration element, keeps FlagInterlaced=1 + FieldOrder=TFF +
full-frame DefaultDuration (40 ms), and Explorer shows 25 fps / MediaInfo
CFR. Fix: MkvTrack::video now passes field_duration_ns == 0 so the element
is no longer written; the 1/DefaultDuration = 25 fps signal (the only one
tools trust) is the full-frame value. Interlace signalling (FlagInterlaced,
FieldOrder=TFF) is retained — MediaInfo reads scan type from the MPEG-2 ES
picture coding extension, so it still reports Interlaced / Top Field First.
Tests pin the new TrackEntry elements (element present/absent + values).
SUB-TASK 2 — opening "menu"/still-frame video. Traced the MPEG-2
opening-GOP path; the wrong/last seq header and PTS-floor-to-0 hypotheses
are RULED OUT with file:line evidence: codecPrivate is the FIRST sequence
header (read once at headers-ready, mkvstream.rs:115 + pipelined_stream.rs:289),
DVD VOBU structure guarantees each title opens on seq header + I-frame (no
mid-GOP open), the parser back-anchors leading still-frames to the disc's
real timeline (mpeg2.rs:296-303), and the muxer anchors base on the opening
keyframe's real PTS so the t=0 floor (mkv.rs:963) never corrupts it.
Regression tests pin all three (parser + muxer level).
SUB-TASK 3 — make --log-level 3 self-sufficient (diag.rs + minimal hooks).
(a) dump the ACTUAL MKV TrackEntry elements written per track
(tag=mkv.track: FlagInterlaced, FieldOrder, DefaultDuration, field duration,
Display dims, codecPrivate hex) so Windows-fps-class metadata is verifiable
from a log alone. (b) capture the first ~100 coded frames per track (raw)
to <output>.opening.bin with a per-frame summary line (tag=mkv.opening.frame:
track, key/delta, size, PTS) so opening-GOP/menu issues are diagnosable from
a future log without the disc. Both gated to log-level 3; normal runs open
no side file and record nothing.
CI gate (Rust 1.86): fmt --check, clippy -D warnings, and test --tests all
green.
Fix three DVD video-attribute bugs surfaced by a PAL disc detected as
NTSC:
- PAL/NTSC: parse video_format from VTS_V_ATR bits 5-4, not bits 1-0
(the old mask read permitted_df, so PAL 576i/25fps was mis-detected
as NTSC 480i/29.97). Named consts replace the magic bit positions.
- Anamorphic aspect: write MKV DisplayWidth/Height from the disc's
display_aspect (16:9 720x576 -> 1024x576) instead of square pixels,
so 16:9 DVDs no longer render as 4:3.
- Colour: stamp SD colorimetry (PAL=BT.470BG, NTSC=SMPTE-170M) instead
of BT.709 (HD).
Adds VideoStream.display_aspect (threaded through every muxer) plus
TvSystem/DvdAspect/ColorSpace plumbing, with regression tests. Removes
the deprecated Disc mux set_halt bridge (use with_halt).
Test-hardening release, no runtime changes. Adds spec-grounded unit tests
across the silent-corruption surfaces — UDF/MPLS/CLPI/IFO parsing, BD/DVD
title + extent assembly, AACS/CSS key handling, TS/PS demux + codec parsers,
MKV/EBML container output, the mux pipeline, sector prefetch + decrypt
decorator, drive/SCSI sense decoding, label extraction, and core I/O. Each
test is grounded in the format spec or real on-disc behavior and verified to
fail under a targeted source mutation. No behavior changed.
Library-wide review-and-fix pass: tightened AACS keydb/handshake/variant
handling and trailing-partial-unit policy, corrected MPLS mark offset and
added UDF allocation bounds, hardened the mux/codec framing and M2TS paths,
guarded SCSI READ CAPACITY short transfers and unified error mapping, added
overflow guards on untrusted disc input, and made prefetch shutdown
deterministic. Release profile now builds with thin LTO + single codegen unit.
Audit-driven fixes (rounds 1–3):
- hevc: correct hvcC profile/level SPS offsets (HEVC has a 2-byte NAL header)
- mkv: map all DTS variants to the registered A_DTS codec id; force a new
cluster before the i16 cluster-relative timestamp can overflow
- ebml/mkvstream: bound untrusted EBML sizes (no multi-GB allocs); reject
uint>8 (was an OOB panic) and non-{0,4,8} float widths (were a desync)
- ts: skip PES-header bytes that span a TS packet boundary; add the PMT
section_len/prog_info_len bounds the PAT parser already had
- ac3: preserve a 0x0B77 syncword split across a PES boundary; cap buffer
- dts: validate each next-core boundary by decoded core size (a 0x7FFE8001
pattern inside XLL payload no longer false-splits/drops the lossless
extension); reject sub-minimum core frames; fix forced-emit PTS base
- lpcm: DVD program-stream PCM no longer double-strips the BD LPCM header
- vc1/mpeg2: do not emit a parameter-set-only PES as a standalone frame
- pgs/truehd: cap the pending reassembly buffer (parity with ac3/dts)
- aacs: ts_syncs_intact uses the exact packet count
- prefetched: capacity-guard the recycled-buffer set_len
- Cargo.toml: exclude project docs from the published crate
Convergence: a third independent audit pass found no remaining material
(CRITICAL/HIGH/MEDIUM) issues. Full precommit (fmt + clippy -D + tests,
Rust 1.86) green.
- MkvTrack::audio emits A_DTS/MA, A_DTS/HR, A_DTS per the DTS family
instead of mislabelling everything as A_DTS. Plex transcoder and
strict hardware decoders reject DTS-HD MA payload under a plain
A_DTS track.
- PgsParser is now stateful: pairs display PCS with the following
empty PCS to compute a duration. Frame::duration_ns + PesFrame::duration_ns
carry it through; MkvMuxer::write_frame gains a final Option<u64>
parameter that emits BlockGroup + BlockDuration when set. Fixes
subtitle bitmaps lingering past their intended end-time.
The 0.18 trait split into FrameSource (read-only) and FrameSink
(write-only) was an over-engineered API. Consumers don't think
"frame source backed by MKV" — they think "open MKV for reading".
The split paid a real API-complexity cost (two trait names, two
re-exports, dual impls per bidirectional type, deprecation bridge)
for one marginal property: compile-time direction-safety at the
trait-object boundary. The runtime error path on a wrong-direction
call (StreamReadOnly / StreamWriteOnly) is unambiguous and rare in
practice.
Deletions:
- pes::Stream is no longer #[deprecated]
- pes::FrameSource trait + its blanket-from-Stream bridge
- pes::FrameSink trait + the trampoline impls on every concrete type
- The compile-time-direction-safety test scaffolding
- Crate-root FrameSource / FrameSink re-exports
Additions:
- Stream is now Send-bounded (Stream: Send supertrait). Every
concrete impl was already Send-compliant — Box<dyn Read + Send>
and Box<dyn Write + Send> were already in place on the trait
objects MkvStream / M2tsStream / etc hold internally. Promoting
Send into the trait makes Box<dyn Stream> Send too, which lets
autorip drop its SendStream unsafe newtype.
The public API is now: one Stream trait, one concrete type per
format, two constructors (open/create or input/output). Bidirectional
types route through internal Mode { Read | Write } discriminants.
Net: -347 lines libfreemkv, -38 lines autorip, -5 lines freemkv.
Per-impl migration of MkvStream / M2tsStream / NetworkStream /
NullStream / StdioStream from the deprecated pes::Stream trait
to the typed pes::FrameSink trait. Both impls coexist during
the 0.18 deprecation window — the existing Stream impls are
unchanged.
The FrameSink::finish signature differs (Box<Self> vs &mut self),
which is why this couldn't be a blanket impl. Each migration
re-borrows the box and delegates to the underlying Stream::finish
body.
FrameSink: Send forced two struct fields (M2tsStream's boxed
Write/Read, MkvStream's boxed WriteSeek/Read) to gain `+ Send`
bounds — minimum surface needed to make the Send-bounded trait
impl-able. mux::resolve::output's local Box<dyn WriteSeek>
construction picks up the same `+ Send`. tests/streams.rs's
shared `stream.write/.finish/.info/.read` calls were
disambiguated to `PesStream::*` to resolve the now-multiple
candidates from coexisting trait impls.
Caller migration (mux::resolve::output return type, autorip,
CLI) is a later slice. This commit only adds new impls; nothing
removed.

Splits the bidirectional pes::Stream into one-direction traits so
calling read() on a write-only sink is a compile error instead of
runtime E9001. Keeps Stream alive as deprecated through 0.18 with a
blanket FrameSource impl so existing concrete types compile unchanged.
FrameSink can't be blanket-impl'd from Stream (different finish
signature), so concrete impls migrate per-type in a follow-up.
Concrete `impl pes::Stream for X` blocks in mux/* and the existing
tests gain a one-line `#[allow(deprecated)]` to keep `-D warnings`
clean during the deprecation window — no behavior changes.

Audit pass against the project docs "no English text in library code" rule.
Found 9 call sites that violated the contract by stuffing English into
io::Error::new(kind, "…") or by abusing Error::DeviceNotFound { path }
as a free-form description field. Each is now a typed Error variant.
New variants and codes: ScsiInterfaceUnavailable (E1004), DeviceLocked
(E1005), IoKitPluginFailed (E1006), UnsupportedPlatform (E2003),
PlatformNotImplemented (E2004), MapfileInvalid (E6011), DiscUrlNotDirect
(E9009).
labels::apply() previously pushed Commentary/Descriptive/Score/IME and
" (Secondary)" English literals into AudioStream.label, leaking into
MKV titles + autorip UI. AudioStream now exposes structured `purpose:
LabelPurpose`, SubtitleStream `qualifier: LabelQualifier`. Callers
translate to localized text. label keeps codec-formatting only.
API hygiene: 11 mux/* modules dropped from `pub` to `pub(crate)` —
their *types* are still re-exported from lib.rs, but the modules were
leaking low-level EBML/TS/network primitives. Stream trait gets a real
rustdoc explaining read-vs-write split. lib.rs grouped re-exports into
documented sections. ScanOptions::with_keydb() removed (one-method-per-
action rule); use struct literal.
Dead-code sweep: removed lookahead.rs (orphan, never declared as mod),
tsreader.rs (TsDemuxReader unused), ebml::{write_int,read_vint,SEEK_*},
ts::{scan_first/last_pts,scan_duration,SCAN_HEAD/TAIL_SIZE,take/set_
remainder}, MkvMuxer codec_private_slots/filled fields and
fill_codec_private method (deferred-codecPrivate path never used since
the v0.10 PES rewrite). cargo clippy --all-targets -D warnings clean.
Tests: new error::tests for variant codes + Display "no English" guard +
io::ErrorKind mapping. 233 lib tests, all green (was 230).
Breaking: ScanOptions::with_keydb removed; mux/* modules pub(crate);
AudioStream and SubtitleStream gained required fields; UnsupportedDrive
{ product_revision: "Renesas not yet implemented" } no longer produced
(use PlatformNotImplemented).
Architecture:
- One stream per format, bidirectional PES (read/write on same type)
- IsoStream merged into DiscStream (one type, any SectorReader)

- ContentReader/OpenDisc/open_title/open_input/open_output deleted
- CountingStream wrapper for progress tracking
Error codes:
- All io::Error English strings replaced with Error enum variants
- From<Error> for io::Error conversion
- Unused variants removed, new stream/mux variants added
Deleted: mkvout.rs, pesout.rs, isowriter.rs, mkv-muxer-plan.md
Updated: all docs, README stream table, CHANGELOG
238 tests, 0 clippy warnings.
Streams are streams — they take impl Read, not Read+Seek or File.
- MkvStream::open takes impl Read (was Read+Seek)
- EBML element skipping uses skip_bytes() instead of seek(Current)
- Byte position tracking uses remaining-bytes counter, not stream_position()
- Removed file_size from open (progress is CLI concern)
- M2tsStream::open takes impl Read (was Read+Seek)
- Buffers first 1MB for FMKV header / PMT scan
- Uses chain reader (buffered head + rest) for sequential reading
- Duration unknown without seeking (0.0) — CLI can set from metadata
- Removed ReadSeek trait (no longer needed)
- WriteSeek kept (MKV muxer container format requires seeking internally)
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.
- 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)
- Unified Stream trait: read() and write() on one type
- PesFrame serialize/deserialize for wire format
- TsDemuxReader: shared BD-TS demux for any Read source
- MkvStream: PES read from MKV (EBML → PesFrame)
- M2tsStream: PES read via TsDemuxReader
- Network/Stdio output: PES serialization directly (no BD-TS wrap)
- Network/Stdio input: deferred (needs PES deserialization protocol)
- TsMuxer for M2TS output from PES frames
- input() and output() functions return Box<dyn Stream>
When the MKV muxer transitions from Scanning to Streaming phase,
it creates a fresh TsDemuxer. The old demuxer's remainder bytes
(partial 192-byte BD-TS packets) were lost, causing the new demuxer
to lose sync. All subsequent feed() calls found 0 packets.
Fix: transfer remainder via take_remainder/set_remainder so the
new demuxer maintains packet alignment.
- Doc comments on DriveSession, find_drives, all Error variants, Result type
