libyuv compile options suboptimal #66

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
libyuv built with gyp uses generic compile options.
built with hammer/scons, different, more optimal options are used.
in particular msse2/ssse3 fastfpu /arch:sse2 should be used.
Affine unittest with C code is a good metric for fpu/sse2 performance.

For now this seems to be controllable enough thru gyp defines, so may not 
require a change.
