I don't think i is the asm. As pad_alpha is 1.0 dy default it should do the
memcpy

GST_DEBUG="videom*:3,default:3" gst-launch-0.10 -v videotestsrc !
video/x-raw-yuv,format="(fourcc)I420" ! videomixer sink_0::alpha=1.0 !
xvimagesink

0:00:01.767935936 17707  0x9170ab0 INFO                 default
blend.c:558:_blend_i420_mmx: Fast copy (alpha == 1.0)

...

and the MEMCPY is a plain memcpy according to blend.c:377.

I thing we should make this as a blocker, as it was working previously (I420
was not supported and it worked via ffmpegcolorspace).
