Hi all,

Any further comment for this single patch?
This version has only changed a little compared with V4 (reviewed by Paul), which is that the check of SIMD has been moved from the wrapper function (in libswscale/x86/yuv2rgb_template.c) to format check (in libswscale/x86/yuv2rgb.c).
While assembly code is exactly same with the V4.

Thank you,
Ting Fu.
