What's the correct way to test this? I tried
$ ffmpeg -input foo.mpg -vcodec libx264 output.avi
with and without the patch and didn't notice any performance
improvement nor any (visible) output difference. If Altivec applies
only to decoding, I've to do some more tests.
And on arm, I get bus errors for the above command line regardless
of what version fo x264 is used.
