Fix Common iPhone OBS Camera Issues

Symptoms:

When adding a Video Capture Device in OBS, your iPhone doesn't appear in the dropdown menu.

Solutions:

1. Trust the Computer: Unlock your iPhone, you should see "Trust This Computer?" prompt. Tap "Trust"
2. Try Different USB Port: Switch to another USB port on your computer, preferably USB 3.0 (blue port)
3. Check Cable: Use official Apple cable or MFi-certified cable. Some third-party cables only charge
4. Restart OBS: Completely quit OBS Studio and reopen it
5. Update iOS: Make sure your iPhone is running iOS 14 or later
6. Reinstall iTunes/Apple Devices (Windows): Ensure Apple device drivers are installed

Symptoms:

iPhone appears in device list, but OBS shows a black screen or no video.

Solutions:

1. Open the App: Make sure "Pro Camera for OBS Studio" is open and you've clicked "Start Wired Camera"
2. Check Permissions: Go to iPhone Settings → Privacy → Camera, ensure the app has permission
3. Unlock iPhone: Keep your iPhone unlocked while streaming
4. Remove and Re-add Source: Delete the video source in OBS and add it again
5. Check OBS Properties: Right-click source → Properties, make sure correct device is selected

Symptoms:

Video appears but is choppy, freezes, or has significant delay.

Solutions:

1. Use USB 3.0 Port: Plug into a blue USB 3.0 port instead of USB 2.0
2. Replace Cable: Try a different, high-quality cable
3. Close Other Apps: Close unnecessary apps on both iPhone and computer
4. Reduce Resolution: Lower the video resolution in OBS properties
5. Check Computer Performance: Make sure your computer isn't overloaded (check CPU usage)
6. Update Graphics Drivers: Ensure your graphics card drivers are up to date

Symptoms:

Video appears sideways or upside down in OBS.

Solutions:

1. Use Transform: Right-click source → Transform → Rotate 90° CW/CCW
2. Lock Orientation: In the app, ensure you're holding the phone in the correct orientation
3. Flip Vertical/Horizontal: Right-click source → Transform → Flip Vertical/Horizontal if needed

Symptoms:

iPhone doesn't appear in the NDI source dropdown in OBS Studio.

Solutions:

1. Check Same Network: Ensure both devices are on the SAME Wi-Fi network (not different networks)
2. Enable Local Network Permission: iPhone Settings → Privacy & Security → Local Network → Enable for app
3. Click Send Button: In the app, make sure you've tapped the "Send" button to start broadcasting
4. Disable VPN: Turn off any VPN on either device
5. Check Firewall: Temporarily disable firewall to test (Windows Defender / macOS Firewall)
6. Allow NDI Ports: Open ports 5353 (mDNS) and 5960-5969 (NDI) in firewall
7. Restart Router: Power cycle your Wi-Fi router
8. Reinstall NDI Plugin: Remove and reinstall OBS NDI plugin

Symptoms:

NDI connection works but frequently disconnects or freezes.

Solutions:

1. Use 5GHz Wi-Fi: Switch to 5GHz band instead of 2.4GHz for better performance
2. Move Closer to Router: Reduce distance between iPhone and Wi-Fi router
3. Reduce Network Traffic: Pause downloads, stop streaming on other devices
4. Close Background Apps: On iPhone, close unused apps to free resources
5. Lower Video Quality: In app settings, reduce resolution or frame rate
6. Check Router Settings: Disable AP Isolation, enable QoS for streaming

Symptoms:

Noticeable delay (more than 200ms) between iPhone and OBS display.

Solutions:

1. Use 5GHz Network: 2.4GHz has higher latency
2. Reduce Network Congestion: Stop other network activities
3. Enable Low Latency Mode: In NDI source properties, check for low latency options
4. Upgrade Router: Consider a better Wi-Fi router with faster speeds
5. Use Ethernet: Connect your computer via Ethernet cable for better stability
6. Consider Wired Connection: For lowest latency, switch to USB wired mode

Symptoms:

Video skips frames, appears choppy or jerky.

Solutions:

1. Reduce Bitrate: Lower the video bitrate in app settings
2. Change Frame Rate: Try 30fps instead of 60fps
3. Lower Resolution: Use 720p instead of 1080p
4. Improve Wi-Fi Signal: Get closer to router or remove obstacles
5. Check Computer Performance: Ensure OBS isn't overloading your CPU
