v0.3.1

[0.3.1] - 2026-06-12

Fixed

• HLS playback on macOS no longer clicks/jumps every few seconds.
  Four cumulative fixes, in order of audible impact:
  • Continuous decode across HLS segments. decode_segment is now
    a StreamDecoder struct that owns one Box<dyn Decoder> for the
    whole stream. The format reader is still rebuilt per segment, but
    the AAC decoder's state (predictor history, SBR/PS continuity,
    encoder priming) persists — so the ~50 ms of priming silence /
    decoder warm-up no longer reappears at every segment boundary.
    This is the model ffplay uses against libavcodec.
  • CpalSink rewrite. Replaced Mutex<VecDeque<u8>> + Condvar
    with an rtrb lock-free SPSC ring and moved the consumer half
    into the cpal callback. The CoreAudio realtime thread now does
    zero locks, allocations, or syscalls per buffer. Resampler upgraded
    from nearest-neighbour (which audibly aliased 44.1 → 48 kHz) to
    linear interpolation between adjacent source frames.
  • 1.5 s sink pre-buffer. Resampler waits for ~1.5 s of source
    frames before priming so brief producer hiccups can't immediately
    underrun. Ring capacity bumped to 512 K samples so the bigger
    pre-buffer fits well under the 50 % cap.
  • Background per-segment prefetch. The playback loop no longer
    .awaits fetcher::prefetch; it's tokio::spawn-ed instead, so
    HTTP latency for upcoming segments is hidden from the gap between
    writes. Cache miss in the main loop still falls back to a
    synchronous fetch, so correctness is preserved.
