FFmpeg运行出现的错误

ffmpeg正常安装后执行ffmpeg时出现如下错误：

ffmpeg: error while loading shared libraries: libavdevice.so.53: cannot open shared object file: No such file or directory

解决办法：

vi /etc/ld.so.conf

加入：/usr/local/lib

执行ldconfig

“The encoder 'aac' is experimental but experimental codecs are not enabled”

重新编译如下命令:

./configure --enable-shared --disable-yasm --enable-libfaac --enable-nonfree --prefix=/root/ffmpeg_build/
