qbz/snapcraft.yaml

# QBZ Snap recipe — SOURCE build of the Slint app (crates/ workspace).
#
# Rewritten 2026-07-02 for the Tauri -> Slint migration (v2.0). This root
# file is what `snapcraft` picks up when building from the repo (local
# builds / any builder pointed at the repo root). packaging/snap/snapcraft.yaml
# is a symlink to THIS file — keep it that way.
#
# NOTE: the CI release path (release-snap.yml) does NOT use this file — it
# builds the binary on a swap-equipped 16 GB runner and wraps it with the
# dump-plugin recipe in packaging/snap-slint/snapcraft.yaml. Reason: the
# qbz_ui rustc peaks ~30 GB (RSS+swap); small remote builders (e.g.
# Launchpad) will OOM building this recipe from source. Keep the runtime
# sections (apps/plugs/stage-packages) in sync with packaging/snap-slint/.

title: "QBZ — Native Qobuz Client for Linux"
version: git
summary: Native Qobuz player for Linux with bit-perfect audio and DAC control
description: |
  QBZ is a native Linux desktop client for Qobuz(TM), built for high-fidelity
  playback with a native audio pipeline (direct ALSA and PipeWire), bit-perfect
  output, exclusive device access, and per-track sample-rate switching for
  external DACs — up to 24-bit / 192 kHz.

  This is the native (Slint) build: a single self-contained binary, no web
  runtime. Features: native Qobuz(TM) streaming, bit-perfect ALSA exclusive
  mode, DAC passthrough, Hi-Res FLAC, queue/playlists/favorites/offline cache,
  local library, Chromecast and DLNA, MPRIS media keys and desktop integration.

  QBZ uses the Qobuz(TM) API but is not affiliated with, endorsed by, or
  certified by Qobuz.
