Creating a Video Display in a GUI

I currently trying to put a video display that will except inputs from multiple cameras and switch seamlessly between different cameras in a GUI that is controlling the cameras that are providing the video. Thus far I have had no success. Does anyone have any ideas???

I haven't done it with two cameras but I have with one camera. I used the preview() function. Have you tried that yet?

I have used preview. However, preview has a few limitations that hinder the development of my GUI that I was trying to avoid.

For example, the program that I am currently using the GUI for is building an image from multiple cameras and then exporting the image to a figure. As I understand it, preview can only read raw video or a file, but not a function variable. So I would have to save to a file and have preview() read that file. This is produces overhead that I’m trying to reduce the program.

Also preview, as I have seen thus far, tends to take over the size of my GUI and I personally have not seen an automated way to scale the size of the preview window to the size of my GUI window.

Thanks for the idea though, if you know a way to get around these two problems. Please let me know. It would be greatly appreciated.
