Have to put some comments on this. Sometime ago we already looked at the subpicture layer of matrox cards. But the disadvantage of this layer is that it only supports a few lookup entries. There are less entries than vdr can handle. Vdr's OSD drawing consists of drawing to several areas and each area has it's own lookup table. Vdr in native mode (without OSD plugins) draws it's OSD in a single area with only a few colors entries. So you'll eventually don't see a problem. When i remember our OSD drawing correct, we map all OSD drawing to a single RGB32 area and so we don't need to have separate areas ourself. -- Stefan Lucke _______________________________________________ Softdevice-devel mailing list [email protected] https://lists.berlios.de/mailman/listinfo/softdevice-devel
