//! Dump `ADV`'s voice chunks as RIFF/XMA, so each can be decoded and identified.
|
|
//!
|
|
//! `intro-audio-decomposed.md` measured that the intro's output is the movie's own
|
|
//! WMA Pro 5.1 track at 0.600 **plus** three streams occupying a front pair, a
|
|
//! centre (with a silent partner) and a rear pair. What it could **not** say is
|
|
//! *which* stream sits where — the assignment there is by position, not content.
|
|
//! The port needs that to weight a positional downmix.
|
|
//!
|
|
//! This writes the chunks out so they can be decoded (ffmpeg has `xma2`) and
|
|
//! correlated against the per-channel residuals.
|
|
//!
|
|
//! cargo run -p sylpheed-formats --example adv_voice_dump -- OUTDIR [MOVIE]
