vs9 vpxenc is slower than linux msys build for windows #535

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
vpxenc built with vs9 takes 76236 ms to encode graytone
vpxenc built with gcc-mingw on linux takes 37000 ms to encode.

vs9 is 2.06 times slower?

Both are release builds.
vs9 sln was upgraded and built with vs2012.

Does this mean the Visual C version disabled assembly?
If so, the instruction on 'yasm' are missing.

We'll look at this when we're closer to a release. Please use Visual Studio for 
now.

Visual Studio build is the issue.
msys build no longer works.
I'm using linux msys cross build for now.

This is for current vp8, as well as vp9.
Possible impact on chromium
