The bad thing is that I can't have many windows open when I start mplayer or DirectFB can't allocate video memory when blitting. I think the surface manager should throw out less used stuff but this doesn't seem to happen consistently. Perhaps the other windows are really busy somehow or video memory may be too fragmented. This is problem happens @ 32bpp with a 32MB card. With a 16 MB card I can't even run XDirectFB @ 32bpp since there won't be enough memory left for the CRTC2 buffers. > > I've attached a patch againgst the latest cvs > > mplayer.

Unfortunately this doesn't help as much as I'd like. Flip() waits for the card to become idle before flipping and since we do Blit() and Flip() in this order the blit will keep the card busy for some time. The wait for idle function polls the status register in a tight loop which keeps my CPU busy. Perhaps it would work better with a dual CPU machine. -- Ville Syrjälä firstname.lastname@example.org http://www.sci.fi/~syrjala/ -- Info: To unsubscribe send a mail to email@example.com with "unsubscribe directfb-dev" as subject.
