Fixes and tests from the second audit across bdnav, labels, ifo, codec
parameter sets, mkv/mp4/stdio, css, aacs, keysource, keys, decrypt and
sector code. An HD DVD copy already in the clear needs no key, with one
encryption decision for every AACS format; image and folder titles are
named by the meta title, else the playlist, as in 1.7.7.
One run context (halt, events, loss counters) serves every stage; keys
come from KeyEvidence into a KeyRing. open_source opens every input,
disc:// included, replacing MuxSource; PesSource/PesSink replace
pes::Stream; one Read stage replaces DiscStream and the byte
prefetcher. iso://, null:// and dir:// are sinks. Dead error variants
(E9009, E9063, E9082) and scaffolding removed.
Every input decrypts through one stage that detects its content, with
strict stale-CPI handling and partial units only at EOF. Damage no
longer ends a rip where usable content remains (E7031, UDF FID,
MPLS/CLPI truncation, whole-disc E7032). M2TS output declares tracks in
an HDMV PMT and paces PCR; network:// allows LAN and loopback and
is_blocked_ip is public; parity goldens pin today's outputs.
MKV read-back carries display shape, colour, frame rate, content
encodings and BCP47 language, and drops malformed blocks with a count.
The FMKV header carries display aspect, CICP, labels, chapters and
format. Live reads refuse a zero read batch (E9085) and treat a stopped
read as a stop. freemkv-unlock becomes a version dep with a git-tag
override; dependency bumps (#27, #28); LPCM keeps its source bit depth; 1.8.0
changelog.
E9077-E9084 for engine remux and preflight refusals; MuxOptions loses
its send deadline. The MKV writer drops unwrap/expect and overflow
paths, tags SDR BT.2020 correctly, leaves out streams with no Matroska
CodecID and derives the Dolby Vision level. On-arrival damage with no
vouching partner is blanked, and a garbled head is damage, not a stop.
A bus-encrypted stream file whose File Entry cannot be located is
re-read, then recorded rather than failing the scan; MKV staging ranges
and E6022 for a partial image. Audio framing chains headers while
resyncing, reports every lost slot, keeps good frames beside corrupt
ones and places locks by PTS, with ADTS and MPEG property fuzzing.
DVD subtitles and audio route by PGC SPST_CTL and AST_CTL instead of
stream ordinal, and MPEG audio is fed from its PES id. The DVD MPEG-2
extension stream rides the IR with its channel count verified by CRC.
Audio framing stops false syncs poisoning a track; PGS and DVD subtitle
parser fixes; E9073 and E7034 declared.
Scan reads UDF and the AACS files before the drive handshake and records
a missing DVD /AACS key file instead of failing. Decryption needs an
explicit AACS unit base and refuses off-grid units; an all-broken
host-cert list is its own error (E7033). Every whole-disc and image to
ISO copy goes through one shared reader that refuses an unkeyable file
up front (E7032). HD DVD XPL tick and timecode fixes; CI action bumps.
Fixes from the mkv, mp4, network and ts sink audit; track timing and
DiscardPadding ride the FMKV wire. MP4 writes DTS per ETSI TS 102 114
(ddts rates and timescales). The MKV PCM depth probe is bounded and
evidence-based. Network receives use keepalive and wait on readiness,
so a Stop or a dead peer ends them.
Disc presence is tri-state per MMC-6, an empty drive fails fast, a
cleaning cartridge reads as no disc, and the tray is unlocked only when
we locked it. BD and DVD LPCM decode to plain PCM, with whole-frame DVD
blocks and the BD layout carried through M2TS.
DVD and HDMV navigation commands follow the reference semantics
(SetGPRMMD, set-links, saturating ADD/MUL, unmasked shifts). Label
detection bounds the BD-J menu walk, opens large jars in place and
tightens Paramount, Deluxe and BD-J feature evidence. The CLPI audit
keys streams by clip and PID; channel layouts keep the LFE split and
TrueHD counts for unnamed layouts.
Read-time key fetches are validated and source, halt and drive faults
surface. Every BDMV/STREAM file is bus-decrypted per the BEE flag and
unit copy-permission bits; a missing or unparseable cert fails safe.
Extract treats a drive Stop as a halt, not a hole. io latches writeback
errors, fixes the read eviction window and never waits on writeback
during seeks.
Bumps Cargo.toml + Cargo.lock to 1.7.6. Also fixes a CI-shape defect the
previous release left behind: dev's CHANGELOG still said
`## [1.7.5] — UNRELEASED` after 1.7.5 shipped (release-orchestrate dated
main but did not push a fresh UNRELEASED heading back to dev). Corrects
that here so the changelog job accepts 1.7.6 on the way to qa:
## [1.7.6] — UNRELEASED
- Version aligned; unified release driven by freemkv 1.7.6.
## [1.7.5] — 2026-09-23
- Version aligned (or actual content, per the shipped main entry).
The driver for 1.7.6 is the freemkv Linux desktop shell (GTK4 +
libadwaita) + rip-finished desktop notification (issue #56).
Version aligned to 1.7.5. No functional change to this crate — the release
is driven by freemkv-unlock mirroring the freemkv-firmware 0.9.0 ABI, where
the drive's separate Ake (0x06) and Bus (0x07) levers are retired into a
single Encryption (0x06) lever.
Fixed
- mux/mp4: honour 64-bit largesize (size==1) and size==0 (run-to-end) in the
capped child-box scan; a largesize sibling previously ended the walk early and
later boxes vanished from a MOV/MP4.
Version 1.6.15 (unreleased) -> 1.7.0; changelog folded under 1.7.0.
Earlier 1.7.0 work remains as its own commits below this one: the
GHSA-j8ww-f5fg-9pmh sector-recycle soundness fix, CI/lint hardening (#15/#17),
docs, and Rob Ekl's scsi raw_command / fd-handoff change (#16).
raw_command clamped CDBs with cdb.len().min(16) instead of routing through
the shared checked_cdb_len guard, so an over-length or empty CDB became a
different command rather than a rejected one; it now returns the crate Result
so a rejected CDB is distinguishable from an I/O failure.
The recovery/Drop fd hand-off lacked a release edge: the teardown swap was not
a release op and the recovery CAS was not an acquire load, so a recovery thread
publishing its fd after Drop drained the slot could miss dead==true and leak the
descriptor. Both sides are now AcqRel, with the execute() drain left at Acquire
(sound via the release-sequence rule). A loom model (cfg(loom) dev-dep, its own
CI job) provides the regression coverage cargo test cannot.
Module docs for fd_handoff and timeline now resolve in their own scope, and item
docs stay within comment-guard's caps.
Fixes#16.
Lower the crate MSRV from 1.97 to 1.94 -- the lowest toolchain on which
`cargo build`, `cargo clippy --all-targets -D warnings`, and
`cargo test --tests` all pass clean. Dependencies floor the build at 1.90
(freemkv-unlock 1.90, zip 1.88), but clippy is only warning-clean from
1.94 (older clippy has a `duplicated_attributes` false positive on
`#![cfg(test)]` and flags a now-documented `let_and_return`). Update
`rust-version` and every `dtolnay/rust-toolchain` CI pin to 1.94.0, and
add a CHANGELOG Unreleased entry.
Extend the byte-provenance coverage added in f7d38ca (currently one
TS-path test) with two PS-path tests driving the real `Mpeg2Parser`:
- `ps_stream_stamps_source_provenance`: the PS path forwards `ps.source`
onto `PesPacket`, so demuxed frames carry `Some(SourcePos)`.
- `ps_stream_carries_feed_base_across_reads`: the cumulative `fed_bytes`
base carries ACROSS read buffers -- a frame decoded from the second
sector is stamped `source.byte >= 2048`, not reset per read.
Also record the f7d38ca provenance fix in the CHANGELOG, inline a
`let_and_return` test binding, and trim a redundant sentence from
`PsDemuxer::feed_at`'s doc comment.
MLP/TrueHD carries predictor + restart state across access units, so after a source transport-stream discontinuity (continuity-counter gap) the parser was splicing post-gap audio mid-stream, decoding against stale state and producing a decoder-choking seam (a burst of "restart header sync incorrect" / "Invalid blocksize" errors that could flag the whole track corrupt).
Honor the source's own gap signal: drop forward to the next CRC-valid major-sync AU (a clean re-init point) before resuming, guarded so it never arms before a validated baseline exists (no stream-head whole-track drop). Mirrors the video keyframe resync and the ResyncGate design. Corrects the "audio has no inter-frame refs" comments in truehd/dts/resync. Adds a regression test.
Version bump and changelog for the 1.6.3 sync. All eight crates ship the
same version, so the crates with no functional change this cycle say so
rather than carrying an empty section.
release.sh dates the heading when it cuts the tag, and refuses a bare
'## [1.6.1]' because it cannot tell an undated heading from one it has
already stamped. Shipping a tag whose public changelog says UNRELEASED is
permanent and cannot be corrected inside that tag, so the check is right
to stop rather than guess.
