Ajout d'un noeud puis vers le cache audio

//! Extensions pour pmoaudio
//!
//! Cette crate fournit des nodes d'extension pour pmoaudio qui dépendent
//! d'autres crates du projet. Elle permet d'éviter les dépendances cycliques
//! en plaçant ces extensions en "bout de chaîne" de dépendances.
//!
//! # Features
//!
//! - `cache-sink` : Active le `FlacCacheSink` qui encode l'audio en FLAC et le stocke dans pmoaudiocache
feat: Add PlaylistSource and ResamplingNode for playlist playback This commit implements a new audio source that reads from pmoplaylist and streams tracks continuously, along with a resampling node to normalize sample rates. ## New Components ### PlaylistSource (pmoaudio-ext) - New source in pmoaudio-ext/src/sources/playlist_source.rs - Reads from pmoplaylist ReadHandle - Decodes tracks from audio cache (pmoaudiocache) - Emits PCM with heterogeneous sample_rate and bit_depth - Polls playlist when empty (configurable interval, default 100ms) - Emits TrackBoundary markers between tracks - Graceful shutdown with EndOfStream on stop - Gated behind 'playlist' feature flag **Design Philosophy:** - Keeps each node simple (single responsibility) - Emits raw PCM without format normalization - Pipeline designer chooses how to handle heterogeneity - Ideal for Radio Paradise (homogeneous streams) - Requires ResamplingNode + ToI24Node for mixed playlists ### ResamplingNode (pmoaudio) - Generic resampling node in pmoaudio/src/nodes/resampling_node.rs - Normalizes variable sample rates to a target rate - Uses libsoxr for high-quality resampling - Automatically detects sample rate changes - Recreates resampler as needed - Preserves chunk type (I16/I24/I32/F32/F64) - Quality adapts to bit depth (Medium/High/Very High) ## Architecture PlaylistSource is placed in pmoaudio-ext to avoid circular dependencies: - pmoaudio-ext depends on: pmoaudio, pmoplaylist, pmoaudiocache - No reverse dependencies = clean dependency graph ## Configuration ### pmoaudio-ext/Cargo.toml - Updated 'playlist' feature to include pmoaudiocache, pmocache, pmoflac - Added sources module export ### pmoaudio - Added resampling_node module - Public export: ResamplingNode ## System Requirements ⚠️ **IMPORTANT**: libsoxr-dev must be installed for compilation See INSTALL_NOTES.md for installation instructions per platform. ## Usage Example ```rust // Radio Paradise (homogeneous 44.1kHz/16bit) let mut source = PlaylistSource::new(playlist, cache); let to_i24 = ToI24Node::new(); source.register(Box::new(to_i24)); // Mixed playlist (needs normalization) let mut source = PlaylistSource::new(playlist, cache); let mut resampler = ResamplingNode::new(48000); // Force 48kHz let to_i24 = ToI24Node::new(); source.register(Box::new(resampler)); resampler.register(Box::new(to_i24)); ``` ## Files Changed - pmoaudio-ext/Cargo.toml: Update playlist feature - pmoaudio-ext/src/lib.rs: Add sources module - pmoaudio-ext/src/sources/mod.rs: New sources module - pmoaudio-ext/src/sources/playlist_source.rs: New PlaylistSource (580 lines) - pmoaudio/src/nodes/resampling_node.rs: New ResamplingNode (350 lines) - pmoaudio/src/nodes/mod.rs: Register resampling_node - pmoaudio/src/lib.rs: Export ResamplingNode - INSTALL_NOTES.md: System requirements documentation ## Future Work - GapInsertionNode (inserts silence between tracks) - CrossfadeNode (fade-in/fade-out mixing) - Examples (deferred until implementation validated)

//! - `playlist` : Active l'intégration avec pmoplaylist (sources et sinks)
Ajout d'un noeud puis vers le cache audio
2025-11-03 06:55:45 +01:00
//! - `all` : Active toutes les features d'un coup
//!
//! # Architecture
//!
//! Cette crate dépend de :
//! - `pmoaudio` : Types de base (AudioSegment, AudioError, etc.)
//! - `pmoaudiocache` (optionnel) : Cache audio pour le stockage FLAC
//! - `pmoflac` (optionnel) : Encodage FLAC
//! - `pmometadata` (optionnel) : Gestion des métadonnées
//! - `pmoplaylist` (optionnel) : Intégration playlist
//!
//! Aucune des crates ci-dessus ne dépend de `pmoaudio-ext`, évitant ainsi
//! tout cycle de dépendances.
