Changed stream_handler to always serve ICY-wrapped FLAC instead of
checking for the Icy-MetaData header. This ensures all clients
(including VLC) receive metadata updates.
Changes:
- Removed conditional ICY/pure FLAC logic
- Always use subscribe_icy() for all connections
- Added standard ICY headers (icy-genre, icy-pub)
- Updated documentation to reflect default ICY mode
This allows clients to see "Now Playing" information without needing
to send specific HTTP headers.
Removed references to non-existent VLC options:
- --icy-metadata (doesn't exist)
- --http-continuous (not needed)
VLC automatically sends the "Icy-MetaData: 1" HTTP header when
connecting to HTTP audio streams, and the server responds with
ICY metadata blocks. No special VLC flags are needed.
Also fixed the stream URL in help text (/stream → /test/stream).
The streaming FLAC implementation was experiencing severe lag warnings
(clients skipping 700-2200 messages) because:
1. The broadcast channel capacity (512) was too small for network backpressure
2. The pipeline had no rate limiting, sending data faster than real-time
Changes:
- Increased BROADCAST_CAPACITY from 512 to 4096 (~5min buffer)
- Added TimerNode (3s lead time) to stream_block example pipeline
- Pipeline now: RadioParadiseStreamSource → TimerNode → StreamingFlacSink
This ensures data flows at real-time playback speed with sufficient
buffering for network jitter, eliminating client lag warnings.
- Fix import paths to use public pmoaudio API instead of private modules
- Change AudioError::ConfigurationError to ProcessingError
- Use Node::new_with_input() instead of non-existent Node::new()
- Fix borrow checker issues in IcyClientStream::poll_read()
- Use flatten() on metadata getters to unwrap Result<Option<T>>
- Fix chunk.get_sample_rate() to chunk.sample_rate()
- Remove get_album_artist() call (not in TrackMetadata trait)
- Update pmoparadise Cargo.toml to enable pmoserver feature for axum
- Simplify example init_logging() call to match new pmoserver API
Creates a new example demonstrating StreamingFlacSink usage with pmoserver
for real-world HTTP streaming testing with media players like VLC.
Features:
- Uses pmoserver instead of raw Axum for realistic testing
- Streams a single Radio Paradise block over HTTP
- Supports both pure FLAC and ICY metadata modes
- Provides /test/stream endpoint for streaming
- Provides /test/metadata endpoint for JSON metadata queries
- Includes health check endpoint
Usage:
cargo run --example stream_block --features full -- <channel_id>
Testing with VLC:
# Pure FLAC mode
vlc http://localhost:8080/test/stream
# ICY metadata mode (Now Playing)
vlc --http-continuous --icy-metadata http://localhost:8080/test/stream
Dependencies:
- Requires pmoserver for HTTP server
- Requires StreamingFlacSink from pmoaudio-ext (http-stream feature)
- Integrated with full feature set (pmoaudio + pmoaudio-ext + pmoserver)
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
