Does X264 Support the 64bits CPU or the double-core CPU?

[beyondway]

Hello,

My question is that does X264 do some optimization or any special algorithm with the 64bits CPU or the double-core CPU?

And, if it does, how exactly can we use it to improve the coding speed while we coding with the double-core CPU?

:confused:

Thanks and Best Regards!

yes, x264 has assembly files with optimized functions for 64-bit processors. You can improve encoding speed on multicore cpu-s by using multiple threads.

Thanks!
Would you just give me more detail information?
I am a new guide of using x264!
Thank you very much!

start by using the forum search function and reading some guides.

err 64bit is only on *nix isn't it? so no to 64 yes to multi-threaded for a windows user.

[Sharktooth]

there were 64bits windows builds floating around. i think squid_80 was providing them.

I've had some weird experiences with the eta timecount being all messed up with that build. I suspect a register isn't being saved correctly but can't pin it down, if anyone experiences the same thing please let me know.

What is this? I find out it is an *.exe file, but I can't use it.

It's x264 CLI. It will only work on 64bit Windows. Use it either at the command line or using a GUI like MeGUI or StaxRip. If you're using MeGUI just overwrite the one in megui\tools\x264, if you're using StaxRip overwrite the one in StaxRip\Applications\x264

But, I think that MeGUI can't call x264.exe because MeGUI is 32-bit application.

[akupenguin]

Doesn't matter.
Thought experiment: If a 32-bit app couldn't call a 64-bit app and vice versa, how could you ever have both on the same computer? Windows Explorer is just an application too...

You will need 64-bit avisynth for MeGUI (and presumably for general use of x264, unless you like mencoder), which will still not have several features, because many of the plugins have no 64-bit version available yet. Still, you have dgdecode and degrainmedian, what more could you need? :p

Alternately you could force MeGUI to work in 32-bit mode and have both 32 and 64-bit avisynth, but all you gain there is severe compatbility problems.

Thank you very much! And now I have a double-core 64 bits CPU, how can I config the codec to using the max resource of the CPU to improve the coding speed?
