This is a relatively minor issue, I just wanted to mention it somewhere. The delogo filter does not include special-casing for logos that touch the side of the screen. Because of that, trying to filter such a logo out will lead to the edge of the logo smearing itself across the delogo'd area. A possible fix would be to special case this situation and allow the user to specify a "border" color on the command line - alternately, wrap around and use the color on the other side of the logo instead.
