Good Morning, I have a question about video overlay and window repainting. I have a project in which I need to show a video on a non-rect part of an application window. After some attempts I decided to use play the video on one window (window 1) and over it put the application window (window 2) where the zone I want the video to show is painted using the color key of the video overlay. With this configuration the video should be shown as if it were embedded in window 2. However, it works only in some situations, which I describe bellow:
1.- If window 1 (video) is completely covered by window 2, the video doesn't show. 2.- If window 1 (video) is not completely covered by window 2 (app) by the left, the video is only show on the part that is not covered. 3.- If window 1 (video) is not completely covered by window 2 (app) by the bottom, the video is only show on the part that is not covered. 4.- If window 1 (video) is not completely covered by window 2 (app) by the bottom and by the left simultaneously, the video is shown on the parts not covered and also on the parts of window 2 (app) which are painted using the color key of the video overlay. For my project, I need to reproduce the behaviour of case 4 in the situation of case 1 but I don't know how to do it. I have tried it with and without a window manager with the same result. I don't know very much about the X server but the problem seems to be that when it needs to update a window, it repaints the minimum rectangle which cover all pixels that need to be updated so it only shows the video in case 4 where the minimum rectangle is the entire window 1 (because of the parts not covered). So my question is, is there a solution for this problem? Can I tell the X server that some windows must be always completely repainted? Is there any other way for managing the video overlay that avoids this problem? Thank you very much in advance.
