I guess this comment is wrong, since Mac is specifically excluded?  I will bring
it up separately.

[Peter Valchev, 2010/03/25 21:47:29]

it's only excluded in the 64-bit case, i'm not familiar at all with mac to know
why though

[fbarchard, 2010/03/26 01:43:42]

For Mac, its my intent to use the linux x264 code.  Does the Mac have a 64 bit
config now?
For BSD, is there a reason you cant use base/yuv_row_linux.cc?
It'll help video performance substantially.

[Peter Valchev, 2010/03/26 23:49:46]

Yes, yuv_row_linux.cc is actually used on BSD :) Most of the *_linux.cc are
actually OK to use on BSD and the gyp configs include them (and they exclude
only select ones that are truly linux-specific)

[fbarchard, 2010/03/30 01:51:02]

I wrote the mac code, and there is only 32 bit version.
But if there is a need for 64 bit, it would be better to port the 64 bit linux
code.
