Fix "PlaylistManager not initialized" error in play_and_cache example.
The error occurred because pmoplaylist's WriteHandle calls
pmoupnp::get_audio_cache() to validate cache pks, but the global
cache registry wasn't initialized.
Changes:
- Add register_audio_cache() and register_cover_cache() functions
- Export them from pmoupnp lib.rs
- Call them in play_and_cache example after creating caches
This mirrors how UpnpServer initializes the cache registry.
Corrections pour que l'exemple utilise les bonnes API:
- Utilisation directe de Cache::new() au lieu de méthodes de config
- Suppression des appels à root() qui n'existent pas
- Utilisation du singleton PlaylistManager() au lieu de new()
- Ajout de cache-sink comme dépendance de playlist feature dans pmoaudio-ext
L'exemple devrait maintenant compiler correctement avec:
cargo run --example play_and_cache --features full -- <channel_id>
Crée un nouvel exemple complet qui démontre l'utilisation de tout le pipeline:
- Téléchargement d'un bloc Radio Paradise
- Cache FLAC via FlacCacheSink
- Playlist alimentée automatiquement
- Lecture en temps réel via PlaylistSource et AudioSink
Architecture à deux pipelines :
Pipeline 1 (Download & Cache):
RadioParadiseStreamSource → FlacCacheSink (avec playlist abonnée)
Pipeline 2 (Playback):
PlaylistSource (lit la playlist) → AudioSink (joue l'audio)
Les deux pipelines s'exécutent en parallèle, permettant la lecture pendant le
téléchargement.
Modifications:
- Ajout pmoaudio-ext avec feature playlist dans pmoparadise
- Nouvelle feature "full" combinant pmoaudio + pmoaudio-ext
- Logs détaillés à tous les niveaux (DEBUG)
Usage: cargo run --example play_and_cache --features full -- <channel_id>
Add a new example that demonstrates downloading a complete Radio Paradise
block and saving each track as a separate FLAC file.
The example:
- Takes a channel ID as argument (0-3)
- Fetches current block metadata
- Creates an output directory ./rp_channel_{id}block{blockid}
- Uses RadioParadiseStreamSource to stream and decode the block
- Uses FlacFileSink to automatically detect TrackBoundary markers
- Saves each track as a separate FLAC file with metadata
Example usage:
cargo run --example download_block --features=pmoaudio -- 0
This demonstrates the full pipeline integration between pmoparadise
and pmoaudio, showing how RadioParadiseStreamSource and FlacFileSink
work together to handle multi-track FLAC blocks seamlessly.
The old streaming API has been completely replaced by RadioParadiseStreamSource
which integrates directly with the pmoaudio pipeline.
Removed:
- src/stream.rs (179 lines) - BlockStream, stream_block(), download_block()
- src/track.rs - Per-track extraction functionality
- examples/stream_block.rs - Obsolete streaming example
- examples/extract_track.rs - Per-track extraction example
- Feature "per-track" and dependencies (hound, tempfile)
Updated:
- Cargo.toml: Removed per-track feature and obsolete examples
- lib.rs: Removed module declarations and re-exports
The new RadioParadiseStreamSource provides:
- Direct integration with pmoaudio pipeline
- FLAC decoding via pmoflac
- Automatic TrackBoundary insertion
- Better performance and lower latency
- Add comprehensive technical documentation (RADIO_PARADISE_STREAM_SOURCE.md)
- Add practical usage example (examples/radio_paradise_stream.rs)
- Document architecture, timing algorithm, and API
- Include both basic and advanced usage patterns with nowplaying stream
