* feat(playback): stream buffering UI, ranged M4A tail prefetch, demuxer fix
Defer seekbar/progress until HTTP stream is armed for both legacy and
RangedHttpSource; show buffering overlay on cover art. Add MP4 tail
prefetch and Symphonia isomp4 bounded-mdat/moov-at-EOF probing so
moov-at-end M4A can start without reading the full mdat.
* feat(hot-cache): spill large ranged streams to disk for promote
When a ranged HTTP download completes above the 64 MiB RAM promote cap,
write the existing buffer once to app-data stream-spill/ and register it
for hot-cache promote (rename) and replay via fetch_data. Analysis seeds
from the spill file up to the local-file cap (512 MiB).
* fix(ui): stream buffering — grayscale cover and static clock icon
Desaturate player and queue cover art while isPlaybackBuffering; keep a
non-animated clock overlay for visibility without the spinning animation.
* fix(playback): review follow-up — tests, i18n, spill cleanup, changelog
Clippy and test layout fixes; stream spill orphan cleanup on startup;
buffering flag guard in progress handler; bufferingStream in all player
locales; CHANGELOG and contributor credits for stream/M4A work.
* docs: attribute stream buffering and M4A streaming to PR #737
* test(audio): avoid create_engine in stream spill unit test
CI runners have no audio output device; test spill take/consume via
the Mutex slot only, matching install_stream_completed_spill tests.
Moves all audio playback code (Symphonia decode, rodio output, HTTP
streaming, gapless, previews, and the seven stream/ source-type
submodules from the prior split) out of the top crate into a new
psysonic-audio crate.
crates/psysonic-audio/ new lib crate, depends on
psysonic-core + psysonic-analysis
src/{engine,helpers,decode,…}.rs flattened layout (no more
extra audio/ namespace level)
src/stream/ seven submodules from M0
src/lib.rs re-exports macros from
psysonic-core and the public
API surface
The audio↔analysis edges identified in the dep survey are now real
crate deps (audio depends on analysis directly: AnalysisCache reads,
recommended_gain_for_target, submit_analysis_cpu_seed). Only the
analysis→audio back-edge goes through the PlaybackQueryHandle port
registered in M2.
Cross-crate ref migrations applied via batch sed:
crate::audio::* → crate::* (intra-crate)
crate::analysis_cache::* → psysonic_analysis::analysis_cache::*
crate::submit_analysis_cpu_seed → psysonic_analysis::analysis_runtime::*
crate::subsonic_wire_user_agent → psysonic_core::user_agent::*
Top crate keeps `crate::audio::*` paths working via
`pub use psysonic_audio as audio;` — lib_commands/cli callers untouched.
`stop_audio_engine` (mac process-exit cleanup) moved into the audio
crate as `pub fn stop_audio_engine` since it reaches AudioEngine
internals; tray.rs now re-exports the moved fn.
Two small visibility promotions in engine.rs:
pub(crate) fn analysis_track_id_is_current_playback → pub
pub(crate) fn ranged_loudness_backfill_should_defer → pub
Behaviour preserving. Cargo check + clippy --workspace clean.
