Re: [x265] How can I enable the AVX2 version of DCT and IDCT?

Hi Ximing, If your machine (and OS also) supports AVX2 instruction set then you are already compiling and using AVX2 version of DCT functions. x265 automatically detects & sets all assembly primitives to highest/latest available instruction sets. When you run encoder, you can check command

[x265] How can I enable the AVX2 version of DCT and IDCT?

I read the source code of the /source/common/vec/dct-sse3.cpp and I found the comments said "Note: We have AVX2 assembly for these functions, but since AVX2 is still somewhat rare on end-user PCs we still compile and link these SSE3 intrinsic SIMD functions". But now both my PC and server support
