- Fix TsDemuxer: dynamic PID table size for DVD PIDs
- Set max read speed after scan for DVD riplock removal
- Disc::copy() hardcoded batch=64 sectors, exceeding BU40N's 60-sector
hw limit. Now accepts batch_sectors param, defaults to 60.
- IFO PGC: playback time at offset 0x04 not 0x02, cell time at cell+4
- DiscStream: set demuxer from content_format (TS for BD, PS for DVD)
- Flush TS/PS demuxers at EOF to avoid losing last PES frame

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)
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.
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.

- All inputs and outputs support PES
- Unified Stream trait: read() and write() on one type
- PesFrame serialize/deserialize for wire format

- 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>
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>.
- 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
- pes.rs: PesFrame, InputStream, OutputStream traits
- sector.rs: SectorReader now public, added FileSectorReader (ISO = file)
- Foundation for unified DiscStream that handles both disc and ISO
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.
Previously returned HandshakeResult with zeros when all host certs
failed. Now returns None. Also propagates volume_id read failure
instead of silently using zeros.
Previously used all-zeros AES key when unit_key_idx was out of range,
producing silently corrupted output. Now returns DecryptFailed error.
Also wired --raw flag through InputOptions → set_raw() on streams.
IsoStream decrypts in its read path using keys from scan.
IOStream trait gets keys() method with default DecryptKeys::None.
Pipeline no longer handles decrypt — just reads decrypted bytes.
- IOStream::keys() default returns DecryptKeys::None
- IsoStream and DiscStream override with real AACS/CSS keys
- Pipeline calls input.keys() instead of separate scan_keys()
- Streams are self-contained: read bytes + provide keys
- Rename DriveSession → Drive across entire codebase
- find_drives() returns Vec<Drive>, find_drive() returns Option<Drive>
- resolve_device() now pub(crate) — internal only
- StreamUrl is now a typed enum (Disc, Mkv, M2ts, Iso, Network, Stdio, Null)
with scheme() and path_str() accessors, replacing struct of Strings
- Add lock_tray() / unlock_tray() for safe disc access during rips
- Improve reset() with eject cycle that clears LibreDrive stuck state
- Add Send bounds to ScsiTransport and PlatformDriver traits
- DiscOptions uses PathBuf instead of String for device/keydb paths
- Update doc example to use new Drive API
- DriveStatus enum: TrayOpen, NoDisc, DiscPresent, NotReady, Unknown
- drive_status(): GET EVENT STATUS NOTIFICATION with TUR fallback
- reset(): PREVENT ALLOW → START STOP → init() escalation
- wait_ready(): tries reset on Illegal Request, falls back to drive_status
- Remaining: standard READ(10) still fails in LibreDrive stuck state
- wait_ready: detects MMkv vendor probe when TUR returns Illegal Request
- scan: capacity fallback to 0 when READ CAPACITY fails
- Still needs: re-init to restore standard SCSI commands, or use raw reads for UDF
- Doc comments on DriveSession, find_drives, all Error variants, Result type
- 24 format! strings inlined (clippy pedantic)
- 25 long hex literals with separators (0xFFFFFFFF → 0xFFFF_FFFF)
- README install example updated to 0.8

- has_profile() check for callers
- AACS 2.0: handshake wired into resolve_aacs() — real VID + read_data_key
- DriveId: added raw_gc_010c field for GET_CONFIG 010C response bytes
- Split AacsError { detail } into 13 specific error variants (AacsCertShort,
AacsAgidAlloc, AacsCertRejected, etc.) with unique error codes E7001-E7012

ClpiParse, UdfNotFound, DiscNoTitles, DiscTitleRange, DiscNoExtents)
- Add WriteError (E5001), KeydbLoad (E8005), MuxLookahead (E9000), MuxWrite (E9001)
- Add OpenDisc API for single-call open+scan+rip workflow
- Remove all English text from error Display impl (code-only output)
- Normalize doc comments to use -- instead of em dash for ASCII consistency
Firmware payload was extracted 12 bytes too early — included handler
table pointers instead of actual microcode. Fixed by scanning for
function table position (VM address pattern) instead of magic offsets.
All 206 profiles regenerated. Cold boot firmware upload should now work.
Two MPLS parsing issues:
1. PGS subtitle (0x90) appearing in audio stream slot: language was read
from audio offset sa[2..5] instead of PG offset sa[1..4], causing
truncation ("ng " instead of "eng"). Fixed by detecting PGS coding
type in audio slots and using correct offset.
2. Secondary PG (PiP subtitle) entries were not consumed, causing
position tracking to drift. Added missing n_pip_pg loop.
3. Added stream_type 5/6/7 attribute parsing for secondary audio/video.
Platform trait is no longer publicly exported. External code uses
DriveSession only — cannot call unlock, load_firmware, calibrate directly.
- Platform trait: pub(crate) with 3 methods only
- All handlers are private methods on Mt1959
- DriveStatus moved to mt1959 internal struct
- init() has guard: no re-init if already ready
- set_read_speed() has guard: no-op if not calibrated
- Removed open_unlocked() — open() is the only entry
- Removed Platform and DriveStatus from public exports
Prevents: out-of-sequence SCSI commands, double-init, wrong firmware writes.
- Removed open_unlocked() — open() is the only entry
- Removed redundant init() call from open_title()
- init() called once in open(), handles everything
- Each function does one thing: open→init→scan→read
status() (sub_cmd 0x13) returns ILLEGAL REQUEST on some drives.
Was retrying 6× with 30s timeouts = 180s hang during init().
Steps 1-10 all pass on hardware:
unlock: OK, load_firmware: OK, calibrate: OK,
register_a: OK, register_b: OK
Only status fails — not needed for reads.
When MPLS STN table parsing drifts (disc-specific alignment issue),
a PGS subtitle entry (coding_type 0x90/0x91) can appear in the audio
stream section. Previously this showed as garbled "ng PGS 5.1" audio.
Fix: guard in stream builder checks if audio-typed streams have
subtitle codecs and reclassifies them as subtitles.
Also: unknown stream types now filtered out (filter_map) instead of
creating fake Video entries that showed as "?" in output.
Tested on V for Vendetta BD — "ng PGS 5.1" gone, clean output.
