Lauri Kasanen 46c5693ea3 swscale/output: Altivec-optimize yuv2plane1_8 ... ./ffmpeg_g -f rawvideo -pix_fmt rgb24 -s hd1080 -i /dev/zero -pix_fmt yuv420p \ -f null -vframes 100 -v error -nostats - 1158 UNITS in planar1, 65528 runs, 8 skips -cpuflags 0 19082 UNITS in planar1, 65533 runs, 3 skips 16.48 speedup ratio. On x86, SSE2 is ~7. Curiously, the Power C version takes as many cycles as the x86 SSE2 version, yikes it's fast. Note that this function uses VSX instructions, but is not marked so. This is because several existing functions also make that mistake. I'll submit a patch moving them once this is reviewed.
