[MPlayer-users] syncfb from cvs not working

[Brian J. Murrell]

I am trying to use the "syncfb" output driver (performs fabulously
with removing tearing from the output and smooth scrolls -- like on
CNN -- really are smooth.  Very smooth.

The problem is that the syncfb that is supplied with Mplayer panics my
kernel and the one from cvs does not work.  I get

# /usr/src/mplayer/p3/mplayer -v -ao alsa5 -vo syncfb /video/test
.mpeg

and a black screen.  Other drivers like fbdev and directfb work fine
on the framebuffer as does the syncfb in mplayer (other than panicing
my kernel after a bit of playing), the syncfb (from the teletux CVS)
does not.

Ideas?
