After database end message on the image viewer control

When requesting a live video stream (without a ​playback controller) using the image viewer control an “After database end” message is periodically displayed for a few seconds. Does anyone know what this message means?

“after database end” is the message you get in playback mode, when trying to show video newer than what was recorded in the system.

I recommend your troubleshooting to begin with making sure you are in live mode as you expect to be.
