Open multiple instances of alfaview
If you want to open multiple instances of alfaview, please note the following:
- Audio Feedback or Echo Issues: The audio from one room may be picked up by the microphone and played back to another instance due to speaker output. This results in a disruptive echo or feedback between rooms. Use headphones instead of speakers, or mute your microphone when you’re not speaking.
- Use of System Resources: Each running instance consumes CPU, RAM, and bandwidth. This increased resource usage can lead to crashes or overheating. Please ensure that your system has sufficient performance.
- Network and Bandwidth: Each running alfaview instance requires its own bandwidth. High bandwidth usage can lead to stuttering, asynchronous audio output, or connection drops.
To open alfaview multiple times so you can be in several rooms at the same time, please follow these steps:
Windows
- Create a shortcut: To do this, search for “alfaview” in the Start menu, right-click on it, and select “Create Shortcut.”
- Right-click on the new shortcut and select “Properties.”
- Add the following parameter to the end of the line in the “Target” field:
--allowmultiple- Example:
"C:\Program Files\alfaview\alfaview.exe" --allowmultiple- Click “OK.”
- Open the desired number of instances of alfaview using the new shortcut.
- Each instance opens in a separate window and uses the same profile.
Windows may only allow one app at a time to access the default camera. Enable multi-camera mode under Settings > Bluetooth & Devices > Cameras, and select the camera you’re using. Scroll down and click the button next to the “Advanced camera options”. Enable the option “Let multiple apps use your camera”.
macOS (macOS Ventura 13 and later)
- Open alfaview as usual.
- Open the terminal: Press Cmd + Spacebar, type “Terminal,” and press Enter.
- Enter the following command to open additional instances:
open -n -a "alfaview"- Each instance opens in a separate window and uses the same profile.
If alfaview is not installed in the /Applications/ folder, adjust the path in the command (e.g., open -n -a “/path/to/alfaview.app”).
If open -n does not work, try the following instead:
osascript -e 'tell app "alfaview" to activate'
osascript -e 'tell app "alfaview" to activate'Linux
- Open the terminal by pressing Ctrl + Alt + T.
- Enter the following command to open two instances:
alfaview --allowmultiple &- If you want to open more than two instances, repeat the entry.
- Each instance opens in a separate window and uses the same profile.
