x264 [info]: using cpu capabilities: none!

[littletim]

Hi all,
I'm using Mencoder encode wmv/rmvb to avi with Xeon 3.0G cpu.

Encoding speed goes from 15fps to 20fps only!:mad::mad:

x264 log :x264 [info]: using cpu capabilities: none!

Mencoder log:

thanks for your help.

Is x264 compiled by yourself? Did you use NASM with it? If you compiled it, it's possible that it didn't compile the ASM parts, which is why it's not "found" anything. Double-check everything enabled in "configure". Also, when you run x264, make sure "--no-asm" isn't used.

Install Yasm (preferably 0.6.2) and build the latest x264 version, install it (to /usr/local with make install) and then rebuild MEncoder. Make sure that there are no other x264 libraries on the system.

And you may want to let x264 use more than one encoding thread by specifying threads=auto in your x264encopts.
