regression test

#ffmpeg-develでDark Shikari氏のregression test用スクリプトを見つけた。

#!/bin/sh
vid=videos/foreman_cif.y4m
for tune in film zerolatency
do for m in "--intra-refresh" ""
  do for j in "" "--no-cabac"
    do for i in "--keyint 250 --slice-max-size 1000" "--no-weightb --interlaced"
      do for p in ultrafast superfast veryfast faster fast medium slow slower
        do ./x264 $vid --quiet --preset $p --tune $tune $i $j $m -o test.h264 --dump-yuv test.yuv
           ~/x264/JM/bin/ldecod.exe -i test.h264 > /dev/null
           cmp test.yuv test_dec.yuv
        done
      done
    done
  done
done

えーと、2x2x2x2x8=128パターンか。
