[mythtv-users] MPEG2 Encoded Program Playback Performance w/VIA Unichrome xvmc

[Jules Gosnell]

I have a 1ghz Ezra running :

FC4
kernel-2.6.12-1.1447_FC4
kernel-devel-2.6.12-1.1447_FC4
kernel-module-via-drm-2.6.12-1.1447_FC4-2.6.7-1.ucr
gcc-4.0.1-4.fc4
xorg-x11-6.8.99.900-0.FC4.ucr.2 (rebuilt with gcc32)
xine-lib-1.1.0-0.lvn.3.4.ucr.1
xine-0.99.4-0.lvn.1.4
mythtv-suite-0.18.1-55.at

I have glxinfo reporting direct rendering enabled.

I have xine playing dvds at about 15-20% cpu (that means I run up Gnome 
with bubblemon, start up xine and read the value off bubblemon - so 
actually xine's usage is a bit lower - maybe 5% or so...), as compared 
to 60-80% without h/w acceleration.

I have MythTV set up to use XvMC, but I just get a 'unable to initialize 
video' error... - log enclosed...

I would be grateful for any help. I have tried rebuilding the myth SRPM 
but it breaks on gcc32 because it doesn't like the '-mtune=pentium4' 
that FC4 rpmbuild seems to throw at it and it breaks on gcc4 because 
some warning has become an error :-(...

I'd be happy to help anyone on FC4 get to where I am.

Anyone any ideas ?

cheers,


Jules
