v2.0

What's new

• NVIDIA support: uses Vulkan renderer instead of OpenGL (nvdec hardware decoding)
• Lock screen: wallpaper pauses instantly on lock, resumes on unlock (D-Bus signal, zero polling cost)
• Fix: minimized/hidden windows no longer keep wallpaper paused
• Fix: mpv window ID set before init (no more black frame timing issues)
• Fix: duration/position signals corrected to double precision
• Fix: GPU detection cached, runs once instead of once per screen
• Fix: play() now uses retry logic same as refreshSource()

v1.5

dde-desktop-videowallpaper-plugin (1.5) stable; urgency=medium

• fix: HiDPI display support - video now renders at physical pixel size
  instead of logical pixels, fixing small video block on scaled displays
• fix: portrait monitor no longer crashes dde-shell on plugin load
• fix: mpv GL context failure is now handled gracefully instead of
  throwing and killing dde-shell
• fix: setProperty renamed to setMpvProperty to avoid Qt base class conflict
• chore: hwdec set to auto for universal GPU compatibility
• chore: video looping enabled by default
• chore: default volume set to 0 (muted) on load

v1.4

What's Changed

Bug Fixes

• Remove resizeEvent override from VideoProxy (fought layout)
• predicateAction lookup uses key() instead of values().contains()
• turnOn() was unsubscribing instead of subscribing WindowAboutToBeBuilded
• ffprobe stdout read before deleteLater() (read-after-free)
• play() early-returns if videos still empty after refreshSource()
• checkResource() debounced to suppress notification spam
• CMakeLists now calls find_package(PkgConfig) before pkg_check_modules
• %0 → %1 in notification string
• Volume migration now persisted to DConfig on first run
• checkResource lambda guarded against stale this after turnOff()
• disableAction no longer wipes pauseOnFullscreen/pauseIdleSeconds

New Features

• Volume control (0–100) replacing binary enableAudio toggle
• Playback speed control (0.25×–2×) persisted in DConfig
• Per-screen video assignment for multi-monitor setups
• applyMpvSettings() applies volume + speed on every play/refresh
• Idle/scale/speed/volume menus use QActionGroup (exclusive)

v1.3 — Bug fixes & HiDPI render correction

fix: bug fixes, HiDPI render correction, async ffprobe, cache sync

- wallpaperconfig: configChanged() now updates cached values before emitting signals
- wallpaperengine: fix enable handler guard, fix play/refreshSource race, fix premature malloc_trim
- wallpaperengine: turnOn() guards against double-call watcher/timer leak
- wallpaperengine: getVideos() now filters by video extension only
- videowallpapermenuscene: ffprobe is now async to avoid freezing the UI thread
- videoproxy: document MpvWidget::setProperty routing to mpv
- rootwidgeteventfilter: replace dynamic_cast with qobject_cast
- mpvwidget: use physical pixels (dpr) for HiDPI displays (fix by @DonkeyKongG3me)
- README: credit @DonkeyKongG3me on Telegram for HiDPI fix
