libfreemkv 0.16.3

//! libfreemkv -- Open source optical drive library for 4K UHD / Blu-ray / DVD.
//!
//! Handles drive access, disc structure parsing, AACS decryption, and raw
//! sector reading. 206 bundled drive profiles. No external files needed.
//!
//! # Quick Start
//!
//! ```no_run
//! use libfreemkv::{Drive, Disc, ScanOptions, find_drive};
//!
//! let mut drive = find_drive().expect("no optical drive found");
//! drive.wait_ready().unwrap();
//! drive.init().unwrap();
//! let disc = Disc::scan(&mut drive, &ScanOptions::default()).unwrap();
//!
//! for title in &disc.titles {
//!     println!("{} -- {} streams", title.duration_display(), title.streams.len());
//! }
//!
//! // Stream via PES pipeline
//! let opts = libfreemkv::InputOptions::default();
//! let mut input = libfreemkv::input("disc://", &opts).unwrap();
//! let title = input.info().clone();
//! let mut output = libfreemkv::output("mkv://Movie.mkv", &title).unwrap();
//! while let Ok(Some(frame)) = input.read() {
//!     output.write(&frame).unwrap();
//! }
//! output.finish().unwrap();
//! ```
//!
//! # Architecture
//!
//! ```text
//! Drive           -- open, identify, unlock, read sectors
//!   ├── ScsiTransport    -- SG_IO (Linux), IOKit (macOS)
//!   ├── DriveProfile     -- per-drive unlock parameters (206 bundled)
//!   ├── DriveId          -- INQUIRY + GET_CONFIG identification
//!   └── Platform
//!       └── Mt1959       -- MediaTek unlock/read (Renesas planned)
//!
//! Disc                   -- scan titles, streams, AACS state
//!   ├── UDF reader       -- Blu-ray UDF 2.50 with metadata partitions
//!   ├── MPLS parser      -- playlists → titles + clips + STN streams
//!   ├── CLPI parser      -- clip info → EP map → sector extents
//!   ├── JAR parser       -- BD-J audio track labels
//!   └── AACS             -- encryption: key resolution + content decrypt
//!       ├── aacs         -- KEYDB, VUK, MKB, unit decrypt
//!       └── handshake    -- SCSI auth, ECDH, bus key
//! ```
//!
//! # AACS Encryption
//!
//! Disc scanning automatically detects and handles AACS encryption.
//! If a KEYDB.cfg is available (via `ScanOptions` or standard paths),
//! the library resolves keys and decrypts content transparently.
//!
//! Supports AACS 1.0 (Blu-ray) and AACS 2.0 (UHD, with fallback).
//!
//! # Error Codes
//!
//! All errors are structured with numeric codes. No user-facing English
//! text -- applications format their own messages.
//!
//! | Range | Category |
//! |-------|----------|
//! | E1xxx | Device errors (not found, permission) |
//! | E2xxx | Profile errors (unsupported drive) |
//! | E3xxx | Unlock errors (failed, signature) |
//! | E4xxx | SCSI errors (command failed, timeout) |
//! | E5xxx | I/O errors |
//! | E6xxx | Disc format errors |
//! | E7xxx | AACS errors |

// ─── Drive lifecycle ────────────────────────────────────────────────────────
//
// `Drive::open(path)` → `wait_ready()` → `init()` → `Disc::scan()`. `Drive`
// owns the SCSI session; `DriveCapture` etc. let advanced callers introspect
// drive identity / profile data for sharing.
pub use drive::capture::{
    CapturedFeature, DriveCapture, capture_drive_data, mask_bytes, mask_string,
};
pub use drive::{Drive, DriveStatus, find_drive};

// ─── Errors ─────────────────────────────────────────────────────────────────
//
// All fallible APIs return `Result<T, Error>`. `Error` is a typed enum with a
// numeric `code()`; **no English text in the library** — applications map
// codes to localized messages. See `error.rs` for the full taxonomy.
pub use error::{Error, Result};

// ─── Drive events (low-level callbacks) ─────────────────────────────────────
pub use event::{Event, EventKind};
pub use identity::DriveId;
pub use profile::DriveProfile;
// Platform trait is pub(crate) — callers use Drive, not Platform directly.

// ─── Decryption (AACS / CSS) ────────────────────────────────────────────────
//
// `Disc::scan()` resolves keys and stores them on `Disc`; in most flows you
// don't touch `DecryptKeys` directly — `DiscStream::new(reader, title, keys, …)`
// accepts whatever `Disc::decrypt_keys()` returned. `decrypt_sectors()` is
// for callers that operate on raw sector buffers (e.g. ISO patching).
pub use decrypt::{DecryptKeys, decrypt_sectors};

// ─── Disc structure ─────────────────────────────────────────────────────────
//
// `Disc::scan()` produces a fully-populated `Disc` (titles, streams, AACS
// state). `Disc::identify()` is the fast path — UDF only, no playlist parse,
// for displaying disc name + format quickly while a full scan runs in the
// background. The codec / channel / resolution enums are the canonical
// structured representation; never compare against display strings.
pub use disc::{
    AacsState, AudioChannels, AudioStream, Clip, Codec, ColorSpace, ContentFormat, DamageSeverity,
    Disc, DiscFormat, DiscId, DiscTitle, Extent, FrameRate, HdrFormat, KeySource, LabelPurpose,
    LabelQualifier, Resolution, SampleRate, ScanOptions, Stream, SubtitleStream, VideoStream,
    classify_damage,
};

// ─── Streams ────────────────────────────────────────────────────────────────
//
// All stream types implement `pes::Stream` — read PES frames from a source,
// write PES frames to a sink. Pick the right type at construction:
//
// - `DiscStream` — physical drive or ISO (any `SectorReader`). Always read.
// - `MkvStream`  — Matroska container. Read on `open()`, write on `create()`.
// - `M2tsStream` — Blu-ray Transport Stream. Read on `open()`, write on `create()`.
// - `NetworkStream` — TCP. Read on `listen()`, write on `connect()`.
// - `NullStream` — write-only black-hole sink. Useful for benchmarks.
// - `StdioStream` — pipe to/from stdin/stdout. Read or write.
//
// Most consumers use the URL resolvers (`input()` / `output()`) which pick
// the right type from a scheme:// URL. Direct construction is for callers
// that need to wire custom readers (e.g. autorip's drive-session reuse).

pub use mux::MkvStream;
pub use mux::NetworkStream;
pub use mux::NullStream;
pub use mux::StdioStream;
pub use mux::{InputOptions, StreamUrl, input, output, parse_url};

// ─── Lower-level surfaces ───────────────────────────────────────────────────
//
// `ScsiTransport` is the platform-abstraction trait Drive uses; expose for
// out-of-tree platform backends. `SectorReader` lets callers feed any byte
// source (test harness, network image, SMB share) into the disc scan
// pipeline; `FileSectorReader` is the standard ISO-on-disk implementation.
