Again some progress :-) . This time with an unmodified DirectFB version.
So I'll bring that back to list.
Mark, thank you for your patience.
Level handling is now working with softdevice and VIA again.
But I had to change some parts, which will influence all other driver
handling too, so I'll have to test all my cards :-( .
The reason was, softdevice allocated the surface on which the OSD is
drawn, via (shortend):
scrDsc.flags = (DFBSurfaceDescriptionFlags) (DSDESC_CAPS |
DSDESC_PIXELFORMAT);
scrDsc.caps = DSCAPS_NONE;
DFB_ADD_SURFACE_CAPS(scrDsc.caps, DSCAPS_FLIPPING);
DFB_ADD_SURFACE_CAPS(scrDsc.caps, DSCAPS_PRIMARY);
DFB_ADD_SURFACE_CAPS(scrDsc.caps, DSCAPS_VIDEOONLY);
scrDsc.pixelformat = DSPF_ARGB;
scrSurface = dfb->CreateSurface (scrDsc);
and _not_ via (shortend) as DOK suggested here
( http://mail.directfb.org/pipermail/directfb-users/2006-May/001848.html ):
osdLayer=dfb->GetDisplayLayer(DLID_PRIMARY);
osdLayer->SetCooperativeLevel(DLSCL_EXCLUSIVE);
osdLayer->SetConfiguration(osdLayerConfiguration);
scrSurface = osdLayer->GetSurface();
