Well, xine does work on G3 CPUs (without AltiVec) as well as on G4 (with
AltiVec). I'd strongly recommend you use an AltiVec enabled kernel if
running on an AltiVec CPU, because otherwise any application using AltiVec
extensions will lead to a kernel oops (or might even have unrecognized
side effects on other applications).
ok, good to know these 'without altivec' bugs are not present on G3.
I'm not sure if there's a way to check for AltiVec support in the kernel
(in addition to the checks on CPU capability that xine already does), but
I'll see if there's a way to work around this crash (other than disabling
AltiVec support altogether)...
i would also like to know about detecting the presence of altivec. there
was a talk about it at last debconf, but i could not get any more info.
there was a discussion in http://bugs.debian.org/225959
Just out of curiosity: What kind of machine is that? Does it really have
32 processors?!
it's a G5, or PowerMac 7,2 to be precise. these bugs are faced on debian
kernels -power4{,-smp} 2.6.12 , which were compiled without altivec
support. so essentially xine and totem have these bugs in sarge.
cheers, piem
