Hi, Thanks Chiachen for the reply.
In my case, I was getting line_length from FBIOGET_FSCREENINFO ioctl as 2560 since the hardware supported 720p resolution. This was the cause of problem since DirectFB was writing 640 pixels (1280 bytes), skipping next 1280 bytes and then writing 640 pixels which seemed as alternate fields. I overrided the line_length to 1280 and it started coming properly. This has raised some questions in my mind. Why is config->width hardcoded to 640 in osdInitlayer function on davinci_osd.c? Isnt this to be set from ioctl? Is there a proper way of solving this problem since i'm overriding the ioctl? 2008/7/9 chiachen <[EMAIL PROTECTED]>: > Hi, Harinandan S, > > Yeah, I have ever come across this problem. > > First, you should run dfbinfo in the terminal, to make sure the layer > support :SCREEN_LOCATION SCREEN_SIZE SCREEN_POSITION > > Second, you could try to adjust the parameters of the layer size, screen > size, screen position. > > This is a sample: > > /* to set the width and height of layer*/ > layer->GetConfiguration(layer, &config) > config.flags |= DLCONF_WIDTH; > config.width = w; > config.flags |= CLCONF_HEIGHT; > config.height = h; > layer->SetConfiguration(layer, &config); > > > You could try it. > Hope that could help you. > > > Best regards, > chiachen > [EMAIL PROTECTED] > 2008-07-09 > > ======= 2008-07-08 20:29, your message: [directfb-users] GTK+ over DirectFB > on Davinci - OSD window display on TV======= > > Hi All, > > I am using GTK+ over DirectFB 1.1.1 on TI Davinci.
