When you look at it like this, what you are trying to do is an overlay where you would have your logo on a transparent background that is in front of the output of the image displayed by xawtv. Transcode will overlay an image such as a logo. I think you can do what you propose using vloopback, transcode and xawtv. Best M. Dickens
