I understand. Will fix my guide ASAP.

I have copied those option from 2 site which I referred.  


http://blog.k-tai-douga.com/article/87476810.html  (Japanese site)

Then I googled about those 3 option and found that as follows:

About qtkit:

I also know that QuickTime is already replaced with AV Faundation on Mac OS X 10.9 and later...

About x11grab_xcb

After I read above two, I thought that I should add "--disable-indev=qtkit" option and "--disable-indev=x11grab_xcb" option for Mac OS X.  If this is wrong, I will remove those option...

About --disable-outdev=sdl, the site which I referred mentions that "If you want to disable SDL in ffmpeg, add '--disable-outdev=sdl' option."  Since I'm installing SDL in ffmpeg compile partition (Diskimage), I thought that I should add this option.  If this is wrong, I will remove those option...
