Hi, thanks a lot, would have been a hard/impossible job to find it by myselfe, cause to me it's an attribute of the frame. I'm one of the guys, who don't see the butter on the table if they're shure that it's in the fridge ;) Cheers, Thomas _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
