What I don't understand is why there is such an issue about root
permissions. v4l devices, for example, have been user-accessible for a
while. Bill - if you are willing to settle for your application to work
with one video card (i.e. ATI) you could get such functionality much
sooner. Just e-mail me what you want (in terms of sync), and I'll try to
include this in our "extended" v4l module (http://gatos.sf.net )
