mplayer настраивают Ошибку: заголовок libavutil/x86/asm.h требуется для общего FFmpeg

В Ubuntu 14.04 я работаю ./configure --enable-gui --enable-xvid-lavc --enable-xv --enable-alsa устанавливать mplayer, когда дело доходит до Checking for FFmpeg .... затем ошибка обнаруживается. Я cat config.log, детали ошибки ниже:
