2 Flash the ISO

Write the ISO to a USB drive using one of these tools:

Windows

Use Rufus — select the ISO, choose your USB drive, click Start. Use DD mode if prompted.

macOS / Linux

sudo dd if=ato-switcher-dev.iso of=/dev/sdX bs=4M status=progress

Replace /dev/sdX with your USB device. Use lsblk to find it.

Proxmox / VM

Upload the ISO to your Proxmox storage, create a VM, and attach the ISO as a CD-ROM. Boot from it.

3 Boot & Setup Wizard

Boot from the USB drive (or VM CD-ROM). The system will start automatically and present a setup wizard on the console:

  1. Keyboard layout — select your keyboard language
  2. Hostname — set the device name on the network (default: ato-switcher)
  3. Network — configure DHCP or static IP
  4. Admin password — set a password for SSH access (user: ato-admin)

After the wizard completes, the mixer starts automatically.

4 Connect

Open a browser and navigate to the device's IP address:

The IP address is displayed on the console after boot. You can also run show-ip from the console at any time.

5 Quick Start

  1. Add inputs — connect NDI sources, SRT streams, or upload media files via the control page
  2. Switch — use the Mixer Desktop to cut, crossfade, or wipe between sources
  3. Add overlays — upload PNG images, assign to OVL 1 or OVL 2 in the Overlays tab, toggle on/off
  4. Add outputs — configure SRT push, RTMP stream, or NDI output via the control page or API
  5. Record — start recording to MP4 or MKV from the control page

NDI Configuration

NDI sources are auto-discovered on the same subnet. For sources on different subnets or VLANs:

  1. SSH into the device: ssh ato-admin@<ip>
  2. Edit /etc/vismixer/default.conf
  3. Add: NDI_EXTRA_IPS=192.168.1.100,192.168.1.101
  4. Restart: sudo systemctl restart ato-switcher

SRT / RTMP Output

Add outputs via the control page or API:

# SRT Push
POST /api/outputs
{
  "type": "srt",
  "url": "srt://destination:9000",
  "auto_start": true
}

# RTMP Push
POST /api/outputs
{
  "type": "rtmp",
  "url": "rtmp://live.twitch.tv/app/YOUR_STREAM_KEY",
  "auto_start": true
}

Install to Disk (Optional)

The ISO runs as a live system by default. To install permanently to the internal disk:

  1. Log in via console or SSH
  2. Run: sudo install-to-disk
  3. Follow the prompts to select the target disk
  4. Reboot and remove the USB drive

This will erase the target disk. Make sure you select the correct device.

SSH Access

ssh ato-admin@<device-ip>

Use the password you set during the setup wizard. Useful commands:
