Is there not to use Timer, you can update the image data to the image memory modules.
Thinks.

Hello,

I suppose, you call in your timer event handler the sequence
startLive()
snapImages()
stopLive()

This starts the live video, shows the live image stream and stops the live video again. The window, that is used to show the live video will be blank again after stopLive(). This is normal, because you need to draw the last image like shown in the "demoapp" sample on your client window.

However, you may show me, what you are doing in your source code.
