From e4a3dd1d3366ae78f7aba6c2776256a334445399 Mon Sep 17 00:00:00 2001 From: Kala Date: Sun, 4 Jan 2026 00:06:45 +0100 Subject: [PATCH 1/6] feat(media): implement fallback mode and enhance scroll label animation This commit implements a complete fallback detection system for the media widget and enhances the scroll label animation for better user experience. Addresses issue #599 where media widget fails with 'Class not registered' COM error on custom Windows builds and systems with COM registration issues. Features Implemented: 1. Fallback Mode Detection (from scratch): - Alternative media detection when Windows Media Session API is unavailable - Handles COM registration failures (WinError -2147221164) gracefully - Audio peak detection using pycaw to monitor active playback - Window title parsing for extracting track information from media players - Proper button state management in fallback mode - Seamless switching between normal and fallback modes 2. Scroll Label Animation Improvements: - Optimized scrolling behavior for better readability - Reduced unnecessary updates to preserve scroll position - Smoother animation transitions 3. UI State Management: - Proper button disable/enable based on media app detection - Buttons initialized as disabled and enabled only when media is active - Execution blocking for disabled controls to prevent unintended actions Technical Implementation: - Enhanced QSingleton for better Qt object lifecycle management - Separated event handlers for normal and fallback modes to prevent conflicts - _on_playback_info_changed() skips processing in fallback mode - _on_media_properties_changed() manages all UI states in fallback mode - Audio session monitoring with peak detection threshold - Window enumeration for media app detection Browser Support Note: Browser media detection code is included but not yet fully functional. The implementation has been left in place for future development or for contributors who may have insights on making browser media detection work reliably in fallback mode. This provides a foundation for extending fallback mode support to web-based media players. Graceful Degradation: The fallback mode provides essential functionality for systems where the Windows Media Session API is unavailable due to COM registration issues as described in #599. This ensures consistent media widget functionality across all Windows 10/11 environments, including custom OS builds like AtlasOS and ReviOS. Test coverage: Verified with Spotify in both normal and fallback modes.

Solution: - Implement global process registry to track all cava instances - Add filesystem-based sentinel using PID for cleanup coordination - Clean up stale sentinel files from dead YASB processes using psutil - Kill all orphan cava.exe processes on first widget initialization - Add robust process termination with timeout and fallback to kill - Register processes in global registry for proper cleanup on exit - Add atexit handler for graceful termination Technical details: - Sentinel file: yasb_cava_cleanup_{PID}.lock in temp directory - Thread-safe with locks to prevent race conditions - 500ms delay after taskkill to ensure complete termination - Automatic cleanup of stale sentinels from dead processes Expected behavior: - On YASB start: All orphan cava processes are killed once - On YASB restart: Previous cava processes properly terminated - On YASB crash: Next start cleans up orphans before starting new ones - On normal exit: All cava processes terminated via atexit Prevents process accumulation across multiple YASB restarts --- src/core/widgets/yasb/cava.py | 140 ++++++++++++++++++++++++++++++++-- 1 file changed, 134 insertions(+), 6 deletions(-) diff --git a/src/core/widgets/yasb/cava.py b/src/core/widgets/yasb/cava.py index 40cbbb5e9..79cfcc7af 100644 --- a/src/core/widgets/yasb/cava.py +++ b/src/core/widgets/yasb/cava.py @@ -15,6 +15,103 @@ from core.widgets.base import BaseWidget +# Global registry to track all active cava processes +_active_cava_processes = [] +_cava_process_lock = threading.Lock() +_cleanup_lock = threading.Lock() + + +def kill_all_cava_processes_sync(): + """ + Kill ALL cava.exe processes unconditionally. + Uses filesystem-based sentinel to ensure execution only once per YASB instance. + Cleans up stale sentinel files from dead YASB processes. + """ + import time + import tempfile + import psutil + + temp_dir = tempfile.gettempdir() + current_pid = os.getpid() + sentinel_file = os.path.join(temp_dir, f"yasb_cava_cleanup_{current_pid}.lock") + + with _cleanup_lock: + # CRITICAL: Clean up stale sentinel files from dead YASB processes + try: + for filename in os.listdir(temp_dir): + if filename.startswith("yasb_cava_cleanup_") and filename.endswith(".lock"): + # Extract PID from filename + try: + pid_str = filename.replace("yasb_cava_cleanup_", "").replace(".lock", "") + old_pid = int(pid_str) + + # Check if process is still alive + if old_pid != current_pid and not psutil.pid_exists(old_pid): + # Process is dead, remove stale sentinel + stale_file = os.path.join(temp_dir, filename) + os.remove(stale_file) + logging.debug(f"Removed stale sentinel file for dead PID {old_pid}") + except (ValueError, OSError): + pass + except Exception as e: + logging.debug(f"Error cleaning stale sentinel files: {e}") + + # Check if cleanup already done for this YASB process + if os.path.exists(sentinel_file): + return + + try: + # Kill ALL cava.exe processes unconditionally + result = subprocess.run( + ["taskkill", "/F", "/IM", "cava.exe"], + capture_output=True, + text=True, + creationflags=subprocess.CREATE_NO_WINDOW, + timeout=5 + ) + + # Check if any processes were killed + if result.returncode == 0: + logging.info("Killed all existing cava.exe processes on startup") + # Wait for processes to fully terminate + time.sleep(0.5) + elif "not found" in result.stderr.lower() or "no tasks" in result.stderr.lower(): + logging.debug("No existing cava.exe processes found on startup") + else: + logging.debug(f"taskkill result: {result.stderr}") + except subprocess.TimeoutExpired: + logging.warning("Timeout while trying to kill cava processes") + except Exception as e: + logging.debug(f"Error killing cava processes: {e}") + finally: + # Create sentinel file to mark cleanup as done for this YASB instance + try: + with open(sentinel_file, 'w') as f: + f.write(str(time.time())) + except Exception: + pass + + +def cleanup_all_cava_processes(): + """Clean up all tracked cava processes -

Features: - Multiple display modes: image, video, text, background-only - Shader effects support (blur, grayscale, sepia, vignette, etc.) - Flexible positioning and sizing options - Animation support for images and videos - Comprehensive validation schema - Full documentation Known limitations: - Shader effects currently non-functional (Qt OpenGL integration issues) - Requires further investigation for shader pipeline Components: - Widget implementation with effect management - Validation schema with comprehensive options - Utility classes for shader and animation handling - Complete documentation with examples This is a work-in-progress feature that provides the foundation for advanced visual overlays. Shader functionality will be addressed in future updates. --- docs/widgets/(Widget)-Overlay-Container.md | 457 ++++++++ .../widgets/overlay_container/__init__.py | 20 + .../overlay_background_media.py | 450 ++++++++ .../overlay_background_shader.py | 544 ++++++++++ .../widgets/yasb/overlay_container.py | 370 +++++++ src/core/widgets/yasb/overlay_container.py | 999 ++++++++++++++++++ 6 files changed, 2840 insertions(+) create mode 100644 docs/widgets/(Widget)-Overlay-Container.md create mode 100644 src/core/utils/widgets/overlay_container/__init__.py create mode 100644 src/core/utils/widgets/overlay_container/overlay_background_media.py create mode 100644 src/core/utils/widgets/overlay_container/overlay_background_shader.py create mode 100644 src/core/validation/widgets/yasb/overlay_container.py create mode 100644 src/core/widgets/yasb/overlay_container.py diff --git a/docs/widgets/(Widget)-Overlay-Container.md b/docs/widgets/(Widget)-Overlay-Container.md new file mode 100644 index 000000000..1df60c3f2 --- /dev/null +++ b/docs/widgets/(Widget)-Overlay-Container.md @@ -0,0 +1,457 @@ +# Overlay Container Widget Options + +| Option | Type | Default | Description | +|-----------------|---------|-------------------------------------------------------------------------|-----------------------------------------------------------------------------| +| `target` | string | `"full"` | Target area for overlay: `"full"` (entire bar), `"left"`, `"center"`, `"right"` (bar sections), `"widget"` (specific widget), or `"custom"` (custom position) | +| `target_widget` | string | `""` | Name of specific widget to overlay (when `target: "widget"`) | +| `position` | string | `"behind"` | Z-order position: `"behind"` or `"above"` | +| `offset_x` | integer | `0` | Horizontal offset in pixels | +| `offset_y` | integer | `0` | Vertical offset in pixels | +| `width` | string/integer | `"auto"` | Width: `"auto"` (match target) or pixel value | +| `height` | string/integer | `"auto"` | Height: `"auto"` (match target) or pixel value | +| `opacity` | float | `0.5` | Overlay opacity (0.0-1.0) | +| `pass_through_clicks` | boolean | `true` | Allow mouse clicks to pass through overlay | +| `z_index` | integer | `-1` | Z-index: `-1` (behind), `0` (same level), `1` (front) | +| `child_widget_name` | string | `""` | Name of widget to display in overlay (optional if using background) | +| `show_toggle` | boolean | `false` | Show toggle button in bar | +| `toggle_label` | string | `"\uf06e"` | Toggle button icon/text | +| `auto_show` | boolean | `true` | Show overlay automatically on startup | +| `callbacks` | dict | `{'on_left': 'toggle_overlay', 'on_middle': 'do_nothing', 'on_right': 'do_nothing'}` | Callbacks for mouse events | +| `container_padding` | dict | `{'top': 0, 'left': 0, 'bottom': 0, 'right': 0}` | Padding for toggle container | +| `container_shadow` | dict | See below | Shadow effect for toggle container | +| `label_shadow` | dict | See below | Shadow effect for toggle label | +| `background_media` | dict | See below | Background media (image/GIF/video) options | +| `background_shader` | dict | See below | Background shader (GPU-accelerated) options | + +## Shadow Options +| Option | Type | Default | Description | +|----------------------|---------|------------|--------------------------------------------------------------| +| `enabled` | bool | `false` | Enable shadow effect | +| `color` | string | `"#000000"`| Shadow color (hex or named color) | +| `offset` | list | `[0, 0]` | Shadow offset `[x, y]` in pixels | +| `radius` | int | `0` | Shadow blur radius in pixels | + +## Background Media Options +| Option | Type | Default | Description | +|----------------------|---------|------------|--------------------------------------------------------------| +| `enabled` | bool | `false` | Enable background media | +| `file` | string | `""` | Full path to media file | +| `type` | string | `"auto"` | Media type: `"auto"`, `"image"`, `"animated"`, `"video"` | +| `fit` | string | `"cover"` | Fit mode: `"fill"`, `"contain"`, `"cover"`, `"stretch"`, `"center"`, `"tile"`, `"scale-down"` | +| `opacity` | float | `1.0` | Media opacity (0.0-1.0) | +| `loop` | bool | `true` | Loop animated media/video | +| `muted` | bool | `true` | Mute video audio | +| `playback_rate` | float | `1.0` | Playback speed (0.1-5.0) | +| `volume` | float | `1.0` | Video volume (0.0-1.0) | +| `offset_x` | int | `0` | Widget position offset -

Use `"full"` for entire bar, `"left"/"center"/"right"` for bar sections, `"widget"` for specific widget, or `"custom"` for custom position. +- **target_widget:** Name of specific widget to overlay (only used when `target: "widget"`). +- **position:** Z-order position relative to bar widgets. Use `"behind"` to place overlay behind widgets or `"above"` to place it in front. +- **offset_x/offset_y:** Fine-tune overlay position with pixel offsets. +- **width/height:** Overlay dimensions. Use `"auto"` to match target size or specify pixel values. +- **opacity:** Overall overlay transparency. 0.0 is invisible, 1.0 is fully opaque. Recommended: 0.3-0.5 for backgrounds. +- **pass_through_clicks:** Critical for interactive widgets! Set to `true` when overlay covers clickable widgets to allow clicks to pass through. +- **z_index:** Fine control over stacking order. `-1` places behind widgets, `0` at same level, `1` in front. +- **child_widget_name:** Name of widget to display in overlay. Can be empty if using only background media/shader. +- **show_toggle:** Show a toggle button in the bar to show/hide the overlay. +- **toggle_label:** Icon or text for the toggle button (supports Font Awesome icons). +- **auto_show:** Automatically show overlay on startup. Set to `false` if you want manual control via toggle button. +- **callbacks:** Mouse event handlers. Default left click toggles overlay visibility. +- **container_padding:** Padding around toggle button container. +- **container_shadow:** Shadow effect for toggle button container. Useful for making button stand out. +- **label_shadow:** Shadow effect for toggle button label. Can create glow effects. +- **background_media:** Display images, GIFs, or videos as overlay background. Supports various fit modes and playback controls. +- **background_media.alignment:** Controls which part of the media is visible when it exceeds the overlay size. For example, `"top-center"` shows the top part of a tall image, while `"bottom-center"` shows the bottom part. +- **background_media.css_class:** Custom CSS class applied to the media widget for advanced styling via CSS (filters, transforms, borders, etc.). +- **background_shader:** GPU-accelerated animated backgrounds using GLSL shaders. Includes 7 presets or load custom shaders. + +> [!NOTE] +> When using Cava widget with `target: "full"`, bars_number is automatically limited to prevent lag (100 for waves_mirrored, 150 for waves). + +## Available CSS Classes +```css +/* Toggle button container */ +.overlay-container-widget .toggle-container { } + +/* Toggle button */ +.overlay-container-widget .toggle-button { } +.overlay-container-widget .toggle-button:hover { } +.overlay-container-widget .toggle-button.active { } + +/* Overlay panel */ +.overlay-panel { } + +/* Background media (with optional custom class) */ +.overlay-background-media { } +.overlay-background-media.your-custom-class { } + +/* Child widget inside overlay (example with cava) */ +.overlay-panel .cava-widget { } +.overlay-panel .cava-widget .widget-container { } +``` + +## Advanced Media Positioning + +Beyond the `alignment` property for coarse positioning, you have **full control** over the visible area of media through the `view_offset_x` and `view_offset_y` properties. + +### Fine Control: view_offset_x and view_offset_y + +These properties allow pixel-perfect control over which part of the media is visible: + +**Config:** +```yaml +background_media: + file: "tall_image.png" + fit: "cover" + alignment: "top-center" # Coarse positioning + view_offset_x: -50 # Shift view 50px left + view_offset_y: -100 # Shift view 100px up +``` + +### Workflow + +1. **Use `alignment`** for initial positioning (e.g., `"top-center"`) +2. **Use `view_offset_x/y`** for precise pixel adjustments +3. **Use `css_class`** for visual styling (filters, borders, etc.) +4. **Iterate** by modifying values until desired result + +### Example: Tall Image + +**Scenario:** 1000px tall image, 32px bar, want to show the part at 300px from top. + +**Config:** +```yaml +background_media: + file: "tall_image.png" + fit: "cover" + alignment: "top-center" + view_offset_y: -300 # Shift view 300px up + css_class: "custom-media" +``` + +**CSS (optional for styling):** +```css +.overlay-background-media.custom-media { + /* Visual filters */ + filter: blur(2px) brightness(0.8); + + /* Borders and shadows */ + border-radius: 8px; + box-shadow: 0 4px 8px rgba(0, 0, 0, 0.3); +} +``` + +### Difference between offset_x/y and view_offset_x/y + +- **`offset_x/y`**: Moves the entire media widget (changes widget position) +- **`view_offset_x/y`**: Shifts the visible area within the media (changes which part is visible) + +### Supported CSS Properties + +```css +.overlay-background-media.my-class { + /* Visual filters */ + filter: blur(3px) brightness(0.8) contrast(1.2) grayscale(30%); + + /* Borders and shadows */ + border-radius: 8px; + box-shadow: 0 4px 8px rgba(0, 0, 0, 0.3); + + /* Additional opacity */ + opacity: 0.8; +} +``` + +**Note:** Qt CSS (QSS) does not support `transform`, so use `view_offset_x/y` for precise positioning. + +## Example Styling +```css +/* Toggle button container */ +.overlay-container-widget .toggle-container { + background: transparent; + padding: 0; +} + +/* Toggle button -
