Changelog

Added:

• Option to disable scene engine (Windows): Added a setting in preferences to turn off the native scene engine and revert to the classic projection mode (requires application restart).

Fixed:

• Freezing when switching scenes (Windows): Fixed the freezing of real-time content (such as browser and timers) when performing successive scene switches.
• Media projection button in browser: Fixed the interference of the floating projection button with page structure, which caused blank slides in image carousels. Also fixed the issue that prevented projecting paused videos displaying a cover image.
• Remote Control update (PWA): Fixed an issue where the service worker in the browser would get stuck in an obsolete state, preventing the remote control interface from loading the latest version after application updates.

Added:

• Toolbar hover activation: Option to automatically trigger scene dropdown menus when hovering over the icon. This option is located within the scene dropdown panel itself.

Fixed:

• High-precision frame rate camera detection: Fixed the incorrect rejection of valid formats with fractional FPS during device enumeration on Windows, preserving the exact frame rate value and keeping cameras available for selection.
• Residual frames when reactivating scenes: Fixed the momentary display of old frames (images, videos, or idle screens) when switching to a media scene on the virtual camera.
• Virtual camera registration in installer: Fixed the failure to register DirectShow filters when installing in all-users mode, ensuring proper permissions and isolation between machine (HKLM) and user (HKCU) scopes.

Added:

• Live recording: Native support for recording Solin scene streams in MP4 format (H.264/AAC), allowing capture of microphone and system audio, with recording controls in the toolbar and editor.
• Guided framing and layer mirroring: Visual tool to facilitate the creation of close-ups and camera crops. Allows previewing and adjusting the focus area over the source with composition guides and applying the crop to fill the screen in the correct aspect ratio, as well as horizontal layer mirroring via the context menu.
• PiP Camera grouping in the toolbar: Organization of scenes in the toolbar into dedicated sections (Configured, PiP Camera, and Others), automatically identifying compositions with a camera overlaid on active content.

Improved:

• Infrastructure and language coverage: Complete correction and update of translation catalogs for all supported languages.

Added:

• Hardware acceleration on Windows (D3D11): Direct processing and output of GPU-decoded videos to the projection and virtual camera, reducing CPU usage.

Improved:

• Automatic scene switching (Solin Scenes): When manually changing scenes during playback, the automatic return to the original scene is maintained if the new scene also displays media. If a scene without media is selected, the system respects the operator's decision and suspends the automatic return.
• General video performance: Optimization in full-screen rendering, previews, and virtual camera, avoiding unnecessary recreation of visual resources.
• Camera active by default: New scenes are now created with the Keep camera active option enabled by default.

Fixed:

• Audio playback on projection: Playing audio files no longer causes flickering in projection windows, improper scene switching, or interruption of media configured for idle mode.
• Stability during rapid media switching: Image and video projections no longer get stuck on old/black frames when switching content quickly.
• Program and Virtual Camera fluidity: Fixed frame rate (FPS) drops when starting playback while the camera and video engine were still in the process of initialization and stabilization.

Fixed:

• Media display: Fixed a failure in the rendering pipeline that could cause projection windows and the virtual camera to remain permanently black during transitions or media loading delays.
• Framing and aspect ratio: Fixed aspect ratio coupling, preventing secondary monitor resolutions (such as 4:3 screens) from altering the framing of images displayed on screens with different aspect ratios.
• Fallback rendering: Fixed the missing opengl32sw.dll library in the Windows installer, ensuring correct software rendering functionality when GPU initialization fails.

Added:

• Scenes and Virtual Camera (Beta - Windows): Native real-time composition engine with support for multiple video sources (local media, physical cameras, and RTSP streams with PTZ control), profile management, GPU-accelerated transitions, and output streaming via DirectShow Virtual Camera.

The system now allows configuring, via a dedicated picker, the exact coordinates for automated virtual clicks on the meeting sharing screen, eliminating the need for manual selection by the user. Details on shortcut and click parameterization can be found in the Configuration Guide.
• OBS return scene definition: Ability to manually override the scene to which OBS will return after media playback ends. By right-clicking a scene in the OBS control panel (located in the Solin toolbar), the selected scene will flash green, indicating it will be the automatic post-playback destination.

Fixed:

• Playback synchronization on fast loads: Resolved an inconsistency where light remote media or media loaded over high-speed connections finished downloading before the first frame was displayed. This behavior caused the media to start in a paused state, requiring manual action to unpause. The playback state is now maintained consistently regardless of local loading time or network reconnections, even on high-speed connections.
• System: Small internal adjustment to the macOS application bundle structure.

Added:

• Camera: Implemented support for camera projection.
• OBS Studio: Added network stream integration. For more details, see this guide.

Fixed:

Improved:

• Linked Folders: Fully integrated linked (cloud-synced) folders into the app’s standard playlist workflow. Items that were previously displayed only in the system’s alphabetical order now support all standard playlist interactions. This includes manual media reordering, export options, and full support for the new section creation feature.

Added:

• macOS support: Introduced native compatibility with the macOS operating system, expanding the availability of the application, which was previously exclusive to Windows environments.
• New web engine for the browser tab: Built a new internal navigation system based on C/C++. The implementation introduces native support for video playback with modern codecs (such as H.264), solving previous format limitations.

Improved:

• Substantial optimization in application size: The structural replacement of the old Chromium-based engine with the new native infrastructure eliminated the loading of massive dependencies. The final executable shows a drastic reduction in volume, delivering a lighter and more efficient application while keeping the visual behavior and interface event management intact.

Added:

• Multiple configuration profiles: Added the possibility to create separate profiles in the application. Although Solin continues to work perfectly with a single profile for most situations (even when managing more than one congregation), this new feature brings flexibility for advanced users or more complex scenarios.
• 16:9 aspect ratio lock in the browser: The browser tab now has an option to lock the display area to 16:9. The aspect ratio is maintained regardless of the current application window size, which is ideal for ensuring proper framing when projecting the live tab on external monitors.
• Start video paused: New option in settings that allows loading videos already in a paused state when clicking play, offering greater control in specific contexts.
• Event-based shortcut automation: A new feature has been introduced that links keyboard shortcuts to application events. It is possible to configure shortcuts to be triggered automatically whenever you start, stop, pause, or unpause media.

Improved:

• Attendance count via Zoom Meetings: The participant counting logic has been improved to facilitate the recording of large groups. In addition to continuing to sum through separators (e.g., "Felipe & Julia" = 2), the system now recognizes a number at the end of the participant's name. For example, renaming to "Alves Family 7" will automatically count 7 people. The number to the right of the name always takes priority over mathematical separators.
• Performance and stability: Small code adjustments and internal enhancements were made to ensure the application runs stably and securely.

Added:

• Zoom Meetings integration: New feature (requires enabling in settings) that automates the use of Zoom during meetings. Includes automatically starting and stopping screen sharing, controls to leave computer audio, and an option to unmute everyone (ideal for allowing brothers to converse after the meeting ends).
• Smart attendance counting in Zoom: Added support for attendance counting. To use it, include separators such as &, |, or + in the user’s name (example: "Felipe & Julia"). The system will automatically count this as 2 people.
• New languages: The system has been expanded and now includes full support for German, Finnish, Dutch, Indonesian, Polish, Swahili, Tagalog, and Ukrainian.

Fixed:

• Sign language support: Improved and resolved a data deduplication issue affecting sign languages, ensuring stable and proper support.

Fixed:

• Stability: Minor bug fixes.

Added:

• Linked folder: Added a new feature in the settings screen that allows selecting a folder synced with cloud services (such as OneDrive, Dropbox, etc.).
• Automatic cloud playlists: With the new linked folder feature, subfolders automatically turn into playlists in the app. This allows sending media even from home directly to the computer remotely, and the files will automatically appear in the app.
• Direct playback in internal browser: Now, when clicking audio or video download buttons in the integrated browser (including the JW Stream platform), the media will automatically play in the app.

Improved:

• Settings interface: The settings tab has been completely redesigned, receiving a new design to offer a more intuitive and pleasant navigation experience (UI/UX).
• Week Selection (Meetings): The dropdown menu used to select specific weeks in the Meetings tab has been redesigned.

Fixed:

• General maintenance: Small internal code adjustments and system optimizations.

• IDLE Screen: Support for setting media from Solin itself or any local image/video from the PC as the idle screen (monitor icon in the bottom left corner).

Improved

• Live Tab Streaming: Enhanced live projection of browser tabs on secondary monitors.

Fixed

• Minor bug fixes.

Added

• Window Preview: New resizable window on the main monitor that mirrors the secondary projection, ideal for screen sharing in virtual meetings (monitor icon).
• Independent Languages: Option to set the interface language separately from the content/media language. This means that the app now works in all languages supported by the official JW website.
• Song Announcement Mode: New option in settings that starts the song video without sound to display the title during the announcement, waiting for the play command to start the music.

Added

• OBS integration feature.
