//! Reading the chapter list out of the player.
|
|
//!
|
|
//! The chapters themselves — what a name claims, what the rest of the file
|
|
//! settles, where the tail begins — live in [`pstr_core::chapters`], because
|
|
//! Android reads its chapter list through its own JNI adapter and must reach
|
|
//! the same verdict as this crate does. Only the mpv read is here.
|
|
//!
|
|
//! Read the same way as the track list — `chapter-list/N/title`, one
|
|
//! sub-property at a time — for the same reason: those are plain strings and
|
|
//! doubles, and a node walk would buy nothing.
