See x86/swscale_template.c, the assignment should only be if pixfmt !=
NV21/12. NV21/12 output writing is obviously different than "regular"
planar YUV, and thus the function does something else also.

yuv2yuvX_altivec() doesn't handle alpha (at all). Should probably be
included in the if() as mentioned above also.
