<DIV> </DIV> <DIV> <DIV> Hi All,<BR></DIV> <DIV> Currently, I have the same problems Jianjun said. </DIV> <DIV> <DIV id="result_box" dir="ltr">Jianjun's mail as follows:</DIV></DIV> <DIV><BR> Currently, I am working on Gtk+/X for embedded system, which runs on an<BR>Intel PXA27x processor. The LCD driver supports three frame buffer layers:<BR>base, overlay1 and overlay2. They are /dev/fb0, /dev/fb1 and /dev/fb2 in my<BR>system. On Xserver there is kdrive server and fbdev driver. I would like the<BR>windowing system to make use of three layers simultaneously.<BR> As for a Video Capture application, the common gtk window should be<BR>placed on fb0, the live video should be on overlay2, while the text or icon<BR>on video should be on overlay1 for the sake of transparent effect.<BR> That is to say, the Gtk application should be able to create windows on<BR>a specified layer, either one of the three frame buffers. And kdrive should<BR>be capable of rendering the window to the correct frame buffer.<BR> But the fbdev driver support only one frame buffer (the base, /dev/fb0)<BR>by default in kdrive server. Also the depth of overlay1 is 19(RGB cover 18<BR>bit, and a transparent bit). But fbdev does not support depth 19.<BR> Is there any solution for this issue?<BR><BR><BR>Best Regards<BR></DIV> <DIV>Jianxiu<BR></DIV></DIV> <DIV> </DIV> <DIV> </DIV><br><br> <hr> <font style="font-size:12px;line-height:15px;"></font><a style="font-size:12px;line-height:15px; color:blue; text-decoration:underline;" href="http://popme.163.com/link/004062_0416_4599.html">飙舞赚QQ秀赢旅行券</a>
