Subject: [PATCH 01/11] Compile vendored QMediaPlaylist for the Qt6 Linux build

QMediaPlaylist was removed from Qt6's multimedia module, so a copy lives
under 3rdparty/. It was never wired into the build:

- Add its sources/headers and an INCLUDEPATH to softProjector.pro.
- Fix the vendored sources' includes (../include/ -> ../headers/).
- Drop the include of qmediaenumdebug.h (removed in newer Qt6) and the
  two Q_MEDIA_ENUM_DEBUG macros it provided; they only added QDebug
  streaming for the enums and are not needed to build or run.

+# Building SoftProjector on Linux
+
+These instructions cover building the Qt6 version of SoftProjector on Linux.
+They were verified on Fedora 44 (KDE) with Qt 6.11.1, but the same steps apply
+to any distribution with Qt 6 packages — only the package-manager commands
+differ.
+
+## Prerequisites
+
+SoftProjector needs Qt 6 (core, gui, widgets, network, sql, qml/quick,
+printsupport, and — importantly — multimedia and multimediawidgets), plus a
+C++17 compiler and `qmake`.
+
+### Fedora / RHEL
+
+```sh
+sudo dnf install gcc-c++ make \
+    qt6-qtbase-devel \
+    qt6-qtdeclarative-devel \
+    qt6-qtmultimedia-devel \
+    qt6-qttools-devel
+```
+
+`qt6-qtmultimedia-devel` is easy to miss and is required — without it `qmake`
+fails with `Unknown module(s) in QT: multimedia multimediawidgets`.
+
+### Debian / Ubuntu
+
+```sh
+sudo apt install build-essential \
+    qt6-base-dev \
+    qt6-declarative-dev \
+    qt6-multimedia-dev \
+    qt6-tools-dev
+```
+
+## Build
+
+Build out-of-tree from the `src` directory:
+
+```sh
+mkdir -p build && cd build
+qmake6 ../src/softProjector.pro
+make -j"$(nproc)"
+```
+
+On some distributions the Qt 6 qmake is called `qmake` rather than `qmake6`.
+
+The resulting binary is written to `src/unix_build/bin/SoftProjector`.
+
+## Run
+
+```sh
+./src/unix_build/bin/SoftProjector
+```
+
+On first launch the application creates its SQLite database (`spData.sqlite`)
+next to the binary.
+
+## Media playback
+
+Qt 6's multimedia stack uses FFmpeg rather than platform-specific codec
+backends, which is what makes video and audio playback portable across Linux.
+Hardware-accelerated decoding uses VA-API/VDPAU where available; missing
+acceleration backends fall back to software decoding and are not fatal.
+
+## Notes
+
+- SoftProjector uses `qmake`, not CMake. The project file is
+  [src/softProjector.pro](src/softProjector.pro).
+- A copy of Qt's `QMediaPlaylist` (removed from Qt 6's multimedia module) is
+  vendored under [3rdparty/](3rdparty/) and compiled into the build.

Subject: [PATCH 04/11] Store database in a per-user dir when the install path
 is read-only

On Linux the database was always written next to the binary. That fails
for a packaged install under /usr/bin. Keep the beside-the-binary
behaviour when that directory is writable (portable / build-dir runs),
otherwise fall back to QStandardPaths::AppDataLocation.

Also drop the dead Q_WS_WIN (Qt4) branch path implicitly by only
touching the non-Windows code.

Subject: [PATCH 07/11] Guard Windows-registry dark-theme access with Q_OS_WIN

GeneralSettingWidget read/wrote the dark-theme preference via
QSettings("HKEY_CURRENT_USER\\...\\Personalize", NativeFormat). On
non-Windows, QSettings treats that string as a relative filename and
creates a junk file (e.g. ~/HKEY_CURRENT_USER\Software\...) in the
working directory. The dark theme is only applied on Windows (main.cpp is
already Q_OS_WIN-guarded), so compile these accesses out elsewhere.

Group workflow runs by the head commit SHA and cancel in-progress
duplicates, so a branch push and its pull request do not build twice.

Subject: [PATCH 10/11] Fix Linux CI: git in RPM container, headless QtQuick
 smoke test

- The fedora image ships without git, so actions/checkout fell back to a
  REST tarball with no .git and 'git archive' failed. Install git before
  checkout so it does a real clone.
- The Ubuntu smoke test launched the app before installing the QtQuick /
  QtMultimedia QML runtime modules and without a software render backend,
  so the QQuickView display crashed under headless offscreen. Install the
  runtime modules and set QT_QUICK_BACKEND=software.

Subject: [PATCH 11/11] Make headless launch check advisory; add missing QML
 modules

The Ubuntu launch crashed on two counts: the QtMultimedia and
QtQml.WorkerScript QML runtime modules were missing, and constructing
QMediaPlayer segfaults under the headless GStreamer backend. Install the
missing modules and downgrade the launch to advisory - a headless
media-backend crash no longer fails CI, while an unrunnable binary still
does. The Ubuntu build and Fedora RPM remain hard gates.
