configure:13747: error: You requested FFmpeg (h264, h263, theora, mp4v-es) but not found...die
config.log中错误如下：
/* end confdefs.h. */

这个错误看起来很奇怪，我so都有，怎么报错？原因是使用的库太新了。需要老的库。多老的库？2.8
http://ffmpeg.org/releases/ffmpeg-2.8.15.tar.bz2
如果还出错：
机器上有别的版本的ffmpg编译库，删除
编译错误。参考：

编辑configure，have_ffmpeg=no改为yes
