Video-Framebuffer with Queue Module
This is how to build a simple “Framebuffer”, using the Queue-module: The video-input is feed into the Queue-module. The Queue Size set the length of the framebuffer-delay. To get the delayed image, we use the Structure Index Member module. Set the Index to “0” (zero) to get the frame, that is delayed by the Queue Size value. Of cause you also have access to all other structure-members from the queue, settings the index value from the Structure Index Member from 0..(Queue Size-1).
To get a bigger delay, you would normally set to Queue Size to a higher value, while setting the Index of the Structure Index Member always to 0.
You do not has to use a video-signal as input source. With that given design, you can build a buffer for any value that are present in your patch.
