不是吧,你怎么测的,我怎么看不出区别:(
avs直接扔32位的x264 avs2yuv pipe 到64位的x264 x264用相同的参数,最后结果平均fps做比较 - G:\RIP\EVA1.11>E:\msys\src\x264\x264.1376.core2 --partitions all --direct auto --level 4.1 --crf 22 --ref 3 --threads auto --weightp 1 --aq-strength 0 --me esa --subme 9 --trellis 2 --no-fast-pskip --psnr --ssim -o EVAtest.mp4 EVA.avs

这里的测试快了8.2%。pipe的时候要加上--frames的参数,不然速度确实和32位相差无几。不加--frames如下 - G:\RIP\EVA1.11>avs2yuv -raw EVA.avs -|E:\msys\src\x264\x264_x64.1376.core2 --partitions all --direct auto --level 4.1 --crf 22 --ref 3 --threads auto --weightp 1 --aq-strength 0 --me esa --subme 9 --trellis 2 --no-fast-pskip --psnr --ssim -o EVAtest_x64.mp4 --fps 24000/1001 - 1920x1080

ps 今天还测试了x264 LAVF/FFMS input public beta test (v2.1),64位比32位快11%,不过它检测片源fps类型的误差较大(只测试了m2ts,有错请指正),把cfr认成vfr,导致最终的成品fps不正确。并且貌似还没办法挂字幕,所以没啥实际用途。
