Video & Camera Issues
Fix camera, video tile, and screen sharing problems in InterMIND.
Video & Camera Issues
Camera Not Detected
| Symptom | Likely cause | Fix |
|---|---|---|
| "Camera not found" or no devices in selector | Camera blocked at OS level | macOS: System Settings → Privacy & Security → Camera → enable browser. Windows: Settings → Privacy → Camera |
| Browser asks for permission every join | Permission was denied or set to "Ask every time" | Address bar → lock icon → set Camera to Allow |
| External webcam not listed | Driver issue or USB hub power | Replug directly into the laptop, not through a hub; reinstall driver |
| Camera works in other apps but not InterMIND | Another tab is holding the device | Close other tabs using the camera (Google Meet, Zoom Web, etc.) and reload |
Black or Frozen Video Tile
| Symptom | Likely cause | Fix |
|---|---|---|
| Your tile shows your avatar instead of video | Camera is off (click the camera icon to toggle) | Toggle camera back on |
| Your tile is black even with camera on | Camera privacy shutter is closed | Open the physical shutter on your webcam |
| Video frozen on your end, others see you fine | Local rendering issue | Reload the page (Cmd/Ctrl+R) |
| Video frozen on others' end | Network bandwidth too low | See Network & Connection |
| Wrong camera being used (e.g. external instead of built-in) | Default device mismatch | Click the arrow next to the camera button → select the right device |
Video Quality Issues
| Symptom | Likely cause | Fix |
|---|---|---|
| Pixelated, low-resolution video | Bandwidth-saving auto-adjust | Move closer to your router, switch to wired; InterMIND auto-restores HD when bandwidth allows |
| Lighting is too dark | Your face is back-lit (window behind you) | Add a front-facing light or sit facing a window |
| Video lag (you move, video stutters) | CPU bottleneck from other apps | Close heavy apps (browser tabs with video, IDEs running builds) |
Screen Sharing
| Symptom | Likely cause | Fix |
|---|---|---|
| "Screen sharing not supported" | Safari ≤16 doesn't support getDisplayMedia() on some platforms | Use Chrome, Edge, or update to Safari 17+ |
| Black screen when sharing on macOS | Screen Recording permission not granted | System Settings → Privacy & Security → Screen Recording → enable the browser, then quit and reopen the browser |
| Audio not shared when sharing a tab | Tab audio sharing requires Chrome/Edge | Switch browsers, or share window without audio and unmute the source |
