I need to write a semi-realtime Linux-based GUI for an embedded app. It pulls data in from two V4L infra-red cameras and displays a synthesized with some somewhat-synchronized data from a sensor array connected over USB-to-serial.
Last time I did this, I wrote it as a svgalib app. This time I'd like to do it in X. Is there a simple framework I can use for this? Anyone here with experience to recommend something?
