Quall Studio 1.0.29

Quall Studio receives a screen or camera from a Quall sender as a native source in OBS Studio over the local network. Devices are discovered automatically; you can also enter an address manually. Each device can be added as a separate source.

Requirements

• OBS Studio 32.2 or newer, 64-bit. Tested with OBS Studio 33.0.1 on Windows and macOS.
• Windows 11 x64 (build 22000 or later).
• macOS 13 or later on Apple Silicon. There is no Intel Mac or Linux package.
• A Quall sender on the same network. Quall 1.0.29 or newer pairs with the code or QR; older versions pair with the PIN.

Get the Quall Studio app
The plugin receives from a device running Quall Studio. Install the free app on the device that sends its screen or camera:

• iPhone and iPad: App Store
• Android: Google Play
• Windows 11: Microsoft Store
• Mac: Mac App Store version awaiting Apple approval.

Install
Close OBS and run the installer for your platform:

• Windows: QuallOBS-1.0.29-x64.msi. It is not code-signed, so Windows SmartScreen may warn (More info > Run anyway).
• macOS: QuallOBS-1.0.29-macos-arm64.pkg (Developer ID signed and Apple-notarized).

Manual install from the ZIP: on Windows, copy the quall-obs folder into %ProgramData%\obs-studio\plugins\. On macOS, copy quall-obs.plugin into ~/Library/Application Support/obs-studio/plugins/.

Connect
Open OBS and add Sources > + > Quall Studio (LAN mirror). On the device, open Quall Studio, choose a screen or camera and start the transmission. In OBS, select the device in the list and click Connect.

• First pairing: OBS shows a 4-digit code. On the device, tap the same number among the three shown. You can also click Show QR and scan it with the phone.
• Next time: the device is remembered and reconnects without a code.
• Older Quall versions: enter the PIN shown in Quall.

Use OBS's own controls to record or stream the scene.

Validation and limitations
The plugin loads in OBS Studio 33.0.1 on Windows x64 and macOS Apple Silicon. On macOS, an iPad running Quall 1.0.29 paired with the 4-digit code and streamed 1080p at 30 fps without loss. End-to-end audio and automatic recovery have not been validated for this release. The macOS packages are Developer ID signed and Apple-notarized. The Windows installer and DLL are not code-signed.
