注:如果要编译mod_av,则需要以下步骤
wget http://download1.rpmfusion.org/free/el/updates/7/x86_64/x/x264-libs-0.148-24.20170521gitaaa9aa8.el7.x86_64.rpm

rpm -hiv x264-libs-0.148-24.20170521gitaaa9aa8.el7.x86_64.rpm
rpm -hiv x264-devel-0.148-24.20170521gitaaa9aa8.el7.x86_64.rpm
cd /usr/local/src/freeswitch/libs
git clone https://gitee.com/nwaycn/libav.git
cd libav
./configure --enable-pic --enable-shared --enable-libx264 --enable-gpl --extra-libs="-ldl"
make
make install
cp /usr/local/lib/pkgconfig/libavcodec.pc /usr/lib64/pkgconfig/

cp /usr/local/lib/pkgconfig/libavfilter.pc /usr/lib64/pkgconfig/

cp /usr/local/lib/pkgconfig/libavresample.pc /usr/lib64/pkgconfig/
cp /usr/local/lib/pkgconfig/libavutil.pc /usr/lib64/pkgconfig/
cp /usr/local/lib/pkgconfig/libswscale.pc /usr/lib64/pkgconfig/
ldconfig
然后
cd /usr/src/freeswitch
重新编译freeswitch ```
