Dear Dennis, I am working on a project that needs to overlay an OSD onto video. The platform is TI Davinci and there are 3 display layers: fb0 – used for The OSD fb1 – Used for video fb2 – alphaplane used to blend fb0 and fb1 together
We initialise the alphaplane with zeros so that by default all the pixels in the OSD layer are invisible (i.e. only video is displayed). The only way to make graphics in the OSD layer visible is to set the corresponding pixel values on the aplhaplane to a certain value > 0. I read in one post here that there is a new TI Davinci driver available in directfb version 1.2 that allows control of the fb2 alphaplane. Here is the post I read: http://www.nabble.com/Re%3A-Anybody-know-this--thanks-in-advance-td13571474.html#a13571474 My question is how exactly is this done? Is it simply a matter of creating an IDirectFBWindow and using SetOpacity ?? I currently have version 1.1 of DirectFB and when I use SetOpacity nothing seems to happen? Thanks for any help on this Ryan American Dynamics -- View this message in context: http://www.nabble.com/TI-Davinci-Driver-question-tp18978313p18978313.html Sent from the DirectFB Dev mailing list archive at Nabble.com. _______________________________________________ directfb-dev mailing list directfb-dev@directfb.org http://mail.directfb.org/cgi-bin/mailman/listinfo/directfb-dev
