> Hi, I am totally new to V4L. Currently I am woking on a project whcih will use two Philip 740 toU USB cam. I need use QT or other GUI tools to show the image obtained from the cams. I can use V4L interface to query the cams, but I don't know how to show them in the window. How can I connect the v4L API to the GUI. Is there a simple example I can study? Just fire up xawtv. It's also got all the different techniques for X display in it - using Xv, copying via shm and pushing pixmaps for remote updates
