Troubleshooting IP Camera Video Issues, Live Streaming Problems, and Video Capture Complications

A 'No Video' message is displayed when there is an issue with the camera setup, such as an unplugged Ethernet cable.

We recommend that you check your camera setup first and ensure it is correctly connected to the PC. If the problem persists, determine whether the issue affects multiple programs or only the NV Play Cricket application.

If video cannot be viewed in other programs, check your camera setup or contact the camera manufacturer's support team.

1. Check Camera Connection via Web Browser:

• Open a web browser and log in to your camera's setup page.
• Confirm that the video preview is visible.
• Consult the camera manual for detailed connection instructions.

2. Check for Timeouts in the NV Play Cricket software:

• Open the View menu.
• Select Video and enable Live Video Statistics.
• Ensure there are no timeouts recorded under the IP Camera section, as they indicate network issues.

Additional Steps:

If video displays correctly in an external browser following the steps above but still shows as No Signal in the software:

• Click on the Video Display and open the Settings cog in the top-right corner.
• Select Reconnect to IP Camera.
  
• Open the Tools > Configuration > Video Capture tab from the software's main menu.
• Click on Advanced Settings under Performance Options.
• Disable Enable Hardware Decoding for Video Capture Devices and then click OK.

This message indicates that the connection to the IP camera has been disrupted. Try the following to resolve this issue:

1. Check Physical Setup:

• Ensure all cables are firmly connected.
• Place devices as close as possible.
• Maintain a clear line of sight between the IP camera and network receiver.
• Remove potential signal interference sources (e.g., microwaves).

2. Check for Network Issues:

• Verify timeouts in Live Video Statistics.
• Try viewing the IP camera feed in an external video player.
• Disconnect unnecessary devices from the network to reduce load.

3. Adjust IP Camera Settings:

• Lower the IP camera resolution by selecting the 720p thirdStream in the Video Capture configuration menu (Tools > Configuration > Video Capture > IP Camera > Settings > Search).
  
• Enable Frame Stabilisation in the advanced IP camera settings (Tools > Configuration > Video Capture > IP Camera > Settings > Show Advanced Settings).
• Disable Use UDP Protocol and Use Low Delay Buffer under Advanced Settings.
  

If the video feed appears distorted or broken, the issue is likely due to poor network conditions. Try the following to resolve this issue:

• Reconnect to the Camera:
  • Open Tools > Configuration > Video Capture > IP Camera > Settings.
  • Use the Search function to reconnect the camera.
• Enable Frame Stabilisation in Advanced Settings (Tools > Configuration > Video Capture > IP Camera > Settings > Show Advanced Settings).
• Disable UDP Protocol (Tools > Configuration > Video Capture > IP Camera > Settings > Show Advanced Settings).
• Enable Use Low Delay Buffer (disable if this does not resolve the issue).

If the video display or live stream is not showing score overlays, follow these steps:

1. Restart the Overlay:

• Right-click the Settings cog in the top-right corner of the Video Display.
• Select Restart Overlay Engine.

2. Check Overlay Graphics Settings:

• Go to Overlay and Watermark Settings and ensure Show Overlay Graphics is enabled (Tools > Configuration > Live Streaming > More Settings > Overlay and Watermark Settings > Show Overlay Graphics).

3. Check Firewall and Antivirus:

• Ensure the NV Play Cricket software has been granted private and public network access in your Windows Defender Firewall.
• Add the Pro Cricket Scorer software to your anti-virus exclusion list.

4. Verify Match Folder Login:

• Go to Tools > Configuration > General.
• Ensure the Match Folder path includes the correct user login (that is, the path has your login name in it).

If live streaming is buffering or playing too quickly, the likely causes are high CPU usage or insufficient internet bandwidth. Try the following to resolve this issue:

1. Check System and Network Performance:

• Open the Live Video Statistics panel and check CPU usage, timeouts, network latency and IP camera health (shown as orange or red).
• Run an internet speed test (minimum 8Mbps upload speed recommended) using a service such as speedtest.net.
• Check the live stream health in your streaming service account (e.g., YouTube).
  

2. Adjust Stream Settings:

• Disable Remote Video Broadcast (Tools > Configuration > Video Capture > Remote Video Connections).
• Lower the Live Stream Resolution to 720p or 480p (Tools > Configuration > Live Streaming > Live Streaming Service).
  
• Reduce the Target Bitrate (e.g., 2,500 to 1,500 for 720p; 1,000 to 700 for 480p) via Tools > Configuration > Live Streaming > Live Streaming Service > Target Bitrate and then restart the live stream.

If ball clips are not aligned with live video, try the following:

• Enable Frame Stabilisation in the advanced IP camera settings (Tools > Configuration > Video Capture > IP Camera > Settings > Show Advanced Settings).
• Open the Live Video Statistics panel and check CPU usage. Try to reduce if above 90% (as detailed in the High CPU Usage section below).
• Reconnect to the Camera (Tools > Configuration > Video Capture > IP Camera > Settings > Search) and select the 720p IP camera substream.

If web clips fail to record or are low quality, follow these steps:

• Open the Live Video Statistics panel and check CPU usage. Try to reduce if above 90% (as detailed in the High CPU Usage section below).
• Disable Hardware Accelerated Video Encoding via Advanced Settings. (Tools > Configuration > Video Capture> Advanced Settings > Encoding and Decoding Settings > Enable Hardware Accelerated Video)
  
• Ensure at least 10GB of free disk space on your laptop.

If your computer’s CPU use is consistently above 90%, try these optimisations:

• Plug laptops into a power socket (avoid running on battery power).
• Close other applications (e.g., web browsers, email clients).
• Reduce the number of camera inputs in Video Capture Settings (Tools > Video Capture).
• Lower camera resolution (e.g., from 1080p to 720p or 720p to 480p).
• Enable Reduce High Frame Rates Automatically in Performance Options (Tools > Configuration > Video Capture > Performance Options) to reduce 60fps inputs to 30fps, and 50fps inputs to 25fps.
• Enable Hardware Accelerated Video Encoding/Decoding via Advanced Settings (Tools > Configuration > Video Capture > Advanced Settings > Encoding and Decoding Settings).
