joren 9402dca7ed Initial implementation of qobuz-qt

- Rust backend (qobuz-backend static lib): Qobuz API client (reqwest/tokio),
  Symphonia audio decoder, CPAL audio output, extern "C" FFI bridge
- Qt 6 frontend mirroring spotify-qt layout: toolbar with playback controls,
  left library dock, central track list, right search panel
- Auth: email/password login with MD5-signed requests; session token persisted
  via QSettings
- Playback: double-click a track → Rust fetches stream URL → Symphonia decodes
  → CPAL outputs to default audio device
- Dark Fusion palette matching spotify-qt feel

Building qobuz-qt

Dependencies

Debian / Ubuntu

sudo apt install -y \
    cmake \
    ninja-build \
    qt6-base-dev \
    qt6-svg-dev \
    libssl-dev \
    libasound2-dev \
    libdbus-1-dev \
    pkg-config \
    curl

# Rust toolchain
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
source "$HOME/.cargo/env"

Arch Linux

sudo pacman -S cmake ninja qt6-base qt6-svg openssl alsa-lib rust

Fedora

sudo dnf install cmake ninja-build qt6-qtbase-devel qt6-qtsvg-devel \
    openssl-devel alsa-lib-devel rust cargo

Build

cmake -B build -G Ninja -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)

The first build will take longer as it compiles the Rust backend via Corrosion.

Run

./build/qobuz-qt

On first launch a login dialog appears. Enter your Qobuz email and password. Credentials are stored via QSettings in the standard user config directory.

Audio Quality

Open File → Settings to choose the preferred streaming quality:

Hi-Res 24-bit/192 kHz (format 27)
Hi-Res 24-bit/96 kHz (format 7)
CD 16-bit (format 6) ← default
MP3 320 kbps (format 5)
