Cleaned up excessive INFO logging that was added during debugging.
Logs are now properly categorized by verbosity:
- Frequent/repeated logs (every chunk) → TRACE
* TimerNode SLEEPING messages
* Broadcaster "Read X bytes" messages
- Occasional/setup logs → DEBUG
* Node::run() starting/spawning
* TopZeroSync received
* Cancelled during sleep
- Important events remain INFO
* Encoder initialization
* Header captured
* Stream ended
* Broadcaster task started
This makes INFO logs clean and useful for production monitoring,
while keeping detailed information available via DEBUG/TRACE levels.
Tested with RUST_LOG=info - output is now clean with only
meaningful events logged.
Affected files:
- pmoaudio/src/nodes/timer_node.rs: SLEEPING → trace, TopZeroSync → debug
- pmoaudio/src/pipeline.rs: Node::run/Spawning → debug
- pmoaudio-ext/src/sinks/streaming_flac_sink.rs: Read bytes → trace
Enhanced logging to INFO level for key TimerNode operations:
- TopZeroSync reception and timer reset
- Sleep operations when lead_time exceeds max_lead_time
- Warning when no timer is set (missing TopZeroSync)
This diagnostic logging confirmed that:
1. TopZeroSync is properly received from RadioParadiseStreamSource
2. TimerNode correctly calculates lead_time and sleeps ~48ms per 50ms chunk
3. Real-time pacing is working as expected (3.0s max lead time)
The backpressure mechanism is functioning correctly - chunks flow at
real-time speed (~50ms per chunk) rather than downloading at maximum speed.
Changes:
- Add TimerNode (pmoaudio/src/nodes/timer_node.rs): Rate-limits audio chunk flow based on timestamps with configurable max_lead_time
- Integrate TimerNode into play_and_cache.rs pipeline: PlaylistSource → TimerNode (3s pacing) → AudioSink
- Improve EOF retry in playlist_source.rs: Wait for prebuffer (512KB) before decoding, retry on temporary EOF with 200ms delay
- Export TimerNode in pmoaudio lib.rs and nodes/mod.rs
Known issue: Cache files may still be truncated when TrackBoundary arrives before pump completes flushing.
This requires allowing parallel write tasks as suggested.
