Yes, it compiles on x86_64 (cvs checkout from today). And kino 0.7.4
compiles also fine with it.
And hey, loading the scenes of an existing project (SMIL) file
needs about 3-4 seconds (estimated) with the old
libdv-0.103, and less than 1 second with the recent libdv.
Good job!

I personally prefer computers talking english with me :-)

But I can try. Tell me, what to do.

excellent. I already deleted your original email.. are you on intel or
amd? we still need an intel test.

OK, in that case, you are probably not the right person to help with
this. We would want someone who is really interested in seeing this
translation.

It is an AMD Athlon 64.

Today I compiled libdv-cvs-2004-10-26 on three 64bit platforms
and ran playdv with pond.dv:

Dual AMD Opteron 2.2GHz
compiles, playdv uses about 16% CPU, framerate fine.

Dual Intel Xeon 3.2GHz with EM64T extension (x86_64 instruction set):
compiles, playdv uses about 13% CPU, framerate fine.

Dual Itanium 2 1.6 GHz
compiles, playdv uses 50% CPU (on complete CPU), framerate bad.

All three machines are running RedHat Enterprise Linux 3.0.
I think, the result is not surprising. The Opteron and the
Xeon-EM64T are almost fully binary comatible as far as I know.
They are running the identical OS in this case, only the kernel as
different.
The Itanium is worse, as there is no asm optimization for it...?

Great! Thank you for doing this.

> The Itanium is worse, as there is no asm optimization for it...?

Correct, this was an x86-64 port, not IA64, which the Itanium uses.

Hmm.. can anyone reproduce the crash on encoding with Kino as recently
reported? Otherwise, we can make a new libdv release.
