Is there a problem if > it is enabled? I have red documents provided by http://ffmpeg.org and tested in my environment then found that: 1.qtkit is still functionable with FaceTime HD camera. So "--disable-indev=qtkit" option don't have any meaning. 2.Without disabling x11grab, xcbx11grab does not function on Mac OS X including XQuartz. So "--disable-indev=x11grab_xcb" option don't have any meaning. 3.I don't have any reason to disable ffmpeg's output to SDL window. So "--disable-outdev=sdl" option too don't have any meaning. I have already re-build my ffmpeg and will correct my guide soon. Regarding my beginning question, video aspect ration correction, my question was wrong. I crop setting value 640x360 crops additional 10x120 pixel from video. Also re-encoding result shows me the video's aspect ratio are not incorrect. I wish I could sink through the floor...
