Solin User Guide

Download Solin from the official website and choose the installer for the computer being used. The main installers support Windows 10 or later and macOS 13 or later.

The first time Solin opens, it asks for a profile. Use a name that clearly identifies the congregation or setup, then choose the interface language and the content language used for songs and meeting media.

Solin does one simple job in OBS: it asks OBS to change scenes at the right moment.

Think of OBS as the video table. One scene shows the camera or the usual meeting view. Another scene shows the Solin projection screen. When Solin starts showing a song, image, or video, OBS can move to the media scene automatically.

Create at least two scenes in OBS: one for the normal view and one for Solin's projected media. Clear names help a lot later, for example Camera and Solin Media.

Tip: keep the media scene simple. If it only needs to show Solin's projection, one monitor-capture source pointing to the secondary monitor is usually enough.

Now prepare OBS so Solin and the meeting app can use it. WebSocket is the connection Solin uses to ask OBS to change scenes. In recent OBS Studio versions it is already included, so you normally only need to turn it on.

If your OBS does not show this menu, update OBS Studio first and try again.

After OBS is ready, connect Solin using the same port and password. When the connection works, Solin can read the OBS scene list and you can choose exactly which scenes should be used.

NDI lets Solin receive the video that OBS is already producing. It can be useful as an alternative to OBS Virtual Camera, for local-network video, or for more advanced setups.

The setup is simple: install DistroAV and the NDI 6 Runtime, restart OBS, turn on the DistroAV Main Output, then let Solin find that source.

Download DistroAV 6.2.1 from the DistroAV release page. On Windows, use distroav-6.2.1-windows-x64-Installer.exe. On macOS, use distroav-6.2.1-macos-universal.pkg.

Then install the NDI 6 Runtime: Windows or macOS.

OBS scene switching controls the video view. Audio is a separate choice. Use the path that is easiest to test and most reliable for the congregation.

One option is to share the computer audio in Zoom when sharing the screen. Another option is to use a virtual mixer to combine the hall microphone and Solin media into one virtual microphone. Examples include MIXLINE on Windows and BlackHole on macOS. If there is already a stable audio setup, it can continue being used.

This setup teaches Solin two things: which Zoom shortcut starts/stops screen sharing, and where to click inside Zoom's sharing window.

After that, the workflow becomes automatic. When Solin starts playing media, Zoom shares the target you chose. When the media stops, Solin tells Zoom to stop sharing.

In Zoom, choose one global keyboard shortcut that starts/stops screen sharing. Then enter that same shortcut in Solin under Auto Screen Share > Share hotkey.

Now tell Solin where to click after Zoom opens the Share window. This is the step that lets Solin choose the right screen automatically.

For fully online meetings, you will usually share Solin's media window instead of a secondary screen. For a cleaner result, adjust Zoom's screen-capture mode before the meeting.

Once the hotkey and click position are saved, join the meeting in Zoom and use Solin normally.

When an image or video starts, Solin opens Zoom sharing and clicks the saved target. When the media ends or projection stops, Solin sends the same Zoom shortcut again to stop sharing.
