//! Structured scan diagnostics — the `--log-level 3` self-diagnosing dump.
|
|
//!
|
|
//! A bug report log must be self-diagnosing: everything needed to explain
|
|
//! *why* freemkv made the choices it did at scan must be in the log, in a
|
|
//! compact, machine-parseable form. This module emits one terse line per row
|
|
//! (title, cell, stream, decision) under the `tracing` target
|
|
//! `freemkv::diag`, which the CLI routes to `log.txt` when `--log-level 3`
|
|
//! (debug) is set.
|
|
//!
|
|
//! Format conventions (stable, greppable):
|
|
//! - Every line is prefixed by a `tag=` so a log scraper can filter
|
|
//! (`disc`, `title`, `dvd.cell`, `dvd.vattr`, `dvd.aattr`, `bd.clip`,
|
|
//! `bd.mark`, `aacs`, `stream`, `decision`).
|
|
//! - Raw bytes are shown as `0xNN` next to their decode so a wrong decode
|
|
//! is obvious against the raw value.
|
|
//! - This module only READS already-parsed scan state — it never re-reads
|
|
//! the disc and never mutates anything.
|
|
//!
|
|
//! The DVD per-cell table (with the raw cell-category byte) is emitted from
|
|
//! the IFO scan itself ([`dump_dvd_cells`]), because the per-cell
|
|
//! `ifo::DvdCell` detail is lowered away before the `Disc` is built. The
|
|
//! `Disc`-level dump ([`dump_disc`]) covers everything that survives
|
|
//! lowering: titles, streams, the picked main feature, and AACS state.
