The demux pipeline is declaration-driven off DiscTitle.streams (build_demux_state,
DiscStream::new, and the MKV writer all key off that list), so 'which streams to
keep' is already a pipeline capability with no public knob. This adds the knob:
- mux/select.rs: StreamSelection { audio, subtitle: PidFilter::All | Only(Vec<u16>) }
+ apply(&mut DiscTitle): keep Video always, keep Audio/Subtitle whose PID the
filter lists, prune the rest (and the parallel codec_privates in lockstep);
error SelectionPidUnknown on a listed PID absent from the title (fail loud, not
a silently-missing track). Pure; 6 unit tests. Re-exported at crate root.
- Error::SelectionPidUnknown (E6014).
- MuxOptions gains (+ derives Default now) applied in mux_stream's
Iso/Session arms before the highway/DiscStream builds demux state (and before
probe_and_remap's DVD AC-3 PID rewrite). InputOptions gains applied
in input()'s iso arm right after the title-index bounds check.
PIDs not languages -- language->PID is caller/engine policy. Default All/All is a
no-op (apply gated on !is_all()), so the no-selection path is byte-identical:
nothing below the title-finalization line changes (ts/ps/demux_thread/
pipelined_stream/mkv/disc untouched). All 2488 lib tests pass on 1.86.
Design: freemkv-private/audit/engine-split/STREAM-SELECTION-DESIGN.md (Fable).
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.
The library's public-facing docs were sitting on the 0.17 trait
surface — Disc::copy, pes::Stream, SectorReader, etc. — even though
all in-tree callers migrated in 0.18 rounds 1-3. With 0.18.1 about
to ship, a user copy-pasting the README sample from crates.io would
have hit a compile error.
This commit is purely doc-side:
- README.md: Quick Start rewritten onto Disc::sweep + Disc::patch
with caller-orchestrated multipass; Streams table footnote and
Architecture row reference FrameSource / FrameSink.
- CHANGELOG.md: 0.18.1 entry describing the redesign — primitives,
trait splits, deprecations (kept alive through 0.18.x, deletion
target 0.18.2), throughput numbers.
- docs/{rip-recovery,api-design,architecture,disc-to-rip,
drive-access,udf}.md: every Disc::copy / pes::Stream /
SectorReader reference updated to the 0.18 trait surface.
- FEATURES.md: deleted (8+ versions stale; capabilities live in
README.md and CHANGELOG.md now, matching the workspace-top
FEATURES.md removal in 84acd65).
- examples/iso_dump.rs: verified compiles against 0.18.1.
No code changes.

Updates docs/ to reflect the recovery-loop strip:
- rip-recovery.md: drops Phase 1/2/3 description, replaces with three-layer
model (Disc::patch multi-pass / DiscStream batch halving / Drive::read
single-shot). Notes that no SCSI resets fire from any retry path.
- drive-access.md: removes SG_SCSI_RESET + STOP/START UNIT escalation
references; SgIoTransport::reset is now kernel SG_IO flush + ALLOW
MEDIUM REMOVAL only.
- src/mux/disc.rs + tests/: cargo fmt cleanup.
- README quick-start gains a multi-pass example using the new
Disc::copy + Disc::patch primitives.
- New docs/rip-recovery.md documents the two-stage rip model: mapfile
format (ddrescue-compatible), CopyOptions/PatchOptions surface, the
pass-1/pass-2 algorithm, and the design decisions (why no MODE
SELECT, why ISO intermediate, why ddrescue mapfile).
No code change.
