Changes:
- Remove all volume management (use VolumeNode in pipeline instead)
- Detect hardware format (I16/U16/F32) at startup
- Accept all AudioChunk formats (I16/I24/I32/F32/F64) as input
- Use optimized SIMD functions from dsp::int_float module
- SharedBuffer stores raw AudioChunk + intermediate F32 buffer
- Callbacks adapted to hardware format with proper conversion
Architecture:
1. AudioChunk pushed to SharedBuffer
2. Lazy conversion to F32 interleaved using dsp functions
3. Callback converts F32 → hardware format (I16/U16) if needed
Benefits:
- SIMD optimized conversions (dsp module)
- Clean separation of concerns (volume in VolumeNode)
- Hardware format detection (use native format when possible)
- Flexible input (accepts any AudioChunk type)
Note: Requires ALSA (libasound2-dev) on Linux for compilation
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>
Implémente AudioSink qui permet la lecture audio en temps réel sur la sortie audio
standard via rodio avec architecture thread-safe.
- Nouveau nœud AudioSink avec thread dédié pour gérer rodio (OutputStream non-Send)
- Accepte tous formats audio (I16/I24/I32/F32/F64) et convertit vers I16
- Support volume, arrêt gracieux, transitions gapless
- Exemples: play_audio.rs et play_with_resampling.rs
- Documentation: INSTALL_LIBSOXR.md mise à jour avec instructions ALSA
- Tests unitaires inclus, tous passent
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
Remove unused FFmpeg-based progressive streaming implementation that was
never completed and is not used anywhere in the codebase.
Changes:
- Delete src/ffmpeg_streaming.rs (173 lines of unfinished code with TODOs)
- Remove ffmpeg module import from lib.rs
- Remove ffmpeg feature from Cargo.toml
- Remove ffmpeg-next dependency from Cargo.toml
The current implementation uses claxon (StreamingPCMDecoder) and symphonia
(decode_block_audio) for FLAC decoding, which are fully functional.
Verified: cargo check passes successfully after removal.
Implement a new pmoaudio source node that streams Radio Paradise blocks
with automatic TrackBoundary insertion at the correct timing.
Features:
- Downloads and decodes FLAC blocks from Radio Paradise API
- Queue management for block IDs via push_block_id()
- Recent blocks cache (10 blocks) to avoid re-downloads
- Automatic TrackBoundary insertion based on sample count timing
- Converts Song metadata to TrackMetadata with cover URLs
- Timeout of 3 seconds for new block IDs (radio real-time)
- Support for 16-bit and 24-bit FLAC audio
Architecture:
- RadioParadiseStreamSourceLogic: Pure business logic implementing NodeLogic
- RadioParadiseStreamSource: Wrapper using Node<> pattern
- Uses logic_mut() for push_block_id() configuration
The node emits:
- TopZeroSync at block start
- TrackBoundary before each song (with same order as next chunk)
- Audio chunks (I16 or I24)
- EndOfStream on timeout or completion
New pmoaudio feature gate with dependencies on:
- pmoaudio, pmoflac, pmometadata, futures-util
Resolved compilation error where netstat2 v0.9.1 was accessing
tcp_info.state instead of tcp_info.tcpi_state on Linux systems.
The latest version 0.11.2 includes the fix for this field name change.
