Low Latency Viewer


Troubleshooting

No software without its problems, here are known issues and some advice what to do when it doesn't work

Known issues

  • On Windows, the joystick control won't work when starting video for a second time. Restart the application instead
  • The program stores the last-used password(s) unencrypted

Troubleshooting

Since version 0.0.10 connection errors are displayed in the video viewport. Some usual errors and their possible causes of failure are:

  • Communiction error: Timeout was reached
    IP Address is wrong? Check your typing, use Ping or a discovery tool  to find the correct one.
    UDP stream is blocked by local firewall or network? Use RTP-over-RTSP instead
    RTSP (port 554) is blocked on network? Use HTTP-JPEG (at a price) as HTTP tunneling is not yet supported
  • Server error: 401 (Unauthorized)
    Wrong username and password: You know what to do

  • Server error: 404 (Not found)
    Did you type the URL yourself? Likely a mistake in there.

When video works but PTZ control doesn't, or the controls in the settings dialog are not working:

  • Guest access is enabled and your credentials are wrong (and the video works because it doesn't require the credentials)

  • HTTPS is enabled, HTTP is disabled. The application doesn't support HTTPS

  • The functions are not supported by the camera (e.g. PTZ on a non-PTZ model, or focus/zoom on a non autofocus or remote zoom model).
