[directfb-users] Setting the video mode to a lower bpp

[Otto Wyss]

I tried to set the bpp via SetVideoMode to lower values (16 and 8) to
see how my CheckDFB looks like but it seems this doesn't work. With
fbset I can reduce the bpp of the frame buffer but DirectFB allways
seems to use the 32 bpp regardless what I specify via SetVideoMode.

This is my source code:

    DFBCHECK (DirectFBInit (NULL, NULL));
    DFBCHECK (DirectFBCreate (&dfb));
    dfb->SetVideoMode (dfb, width, height, m_var_info.bits_per_pixel);
    dfb->SetCooperativeLevel (dfb, DFSCL_NORMAL);
    dsc.flags = DSDESC_CAPS;
    dsc.caps  = (DFBSurfaceCapabilities)(DSCAPS_PRIMARY | DSCAPS_FLIPPING);
    DFBCHECK (dfb->CreateSurface( dfb, &dsc, &primary ));

Can anyone say what's wrong?
