安装记录

yum install -y autoconf automake cmake freetype-devel gcc gcc-c++ git libtool make mercurial  pkgconfig zlib-devel

mkdir /software

tar -zxvf  ffmpeg_sources.tar.gz  -C /software

tar -zxvf nasm-2.13.02rc2.tar.gz  -C /software

cd /software/nasm-2.13.02rc2
./configure --prefix="/software/nasm"
make
make install
修改环境变量vim /etc/profile
加入export PATH=/software/nasm/bin:/software/ffmpeg_build/bin:$PATH
然后source /etc/profile

cd /software/ffmpeg_sources/yasm
autoreconf -fiv
./configure --prefix="/software/ffmpeg_build" --bindir="/software/ffmpeg_build/bin"
make && make install

cd /software/ffmpeg_sources/x264
#PKG_CONFIG_PATH="/software/ffmpeg_build/lib/pkgconfig" ./configure --prefix=/software/ffmpeg_build --bindir=/software/ffmpeg_build/bin --enable-static
PKG_CONFIG_PATH="/software/ffmpeg_build/lib/pkgconfig" ./configure --prefix=/software/ffmpeg_build --bindir=/software/ffmpeg_build/bin --enable-static --disable-asm
make && make install

cd /software/ffmpeg_sources/x265/build/linux
cmake -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX="/software/ffmpeg_build" -DENABLE_SHARED:bool=off ../../source
make && make install

cd /software/ffmpeg_sources/fdk-aac
autoreconf -fiv
./configure --prefix="/software/ffmpeg_build" --disable-shared
make && make install

cd /software/ffmpeg_sources/lame-3.99.5
./configure --prefix="/software/ffmpeg_build" --bindir="/software/ffmpeg_build/bin" --disable-shared --enable-nasm
make && make install

cd /software/ffmpeg_sources/opus
autoreconf -fiv
./configure --prefix="/software/ffmpeg_build" --disable-shared
make && make install

cd /software/ffmpeg_sources/libogg-1.3.2
./configure --prefix="/software/ffmpeg_build" --disable-shared
make && make install
make distclean

cd /software/ffmpeg_sources/libvorbis-1.3.4
LDFLAGS="-L/software/ffmeg_build/lib" CPPFLAGS="-I/software/ffmpeg_build/include" ./configure --prefix=/software/ffmpeg_build --with-ogg=/software/ffmpeg_build --disable-shared
此时如果有如下报错
checking for OGG... no
checking for Ogg... no
*** Could not run Ogg test program, checking why...
*** The test program compiled, but did not run. This usually means
*** that the run-time linker is not finding Ogg or finding the wrong
*** version of Ogg. If it is not finding Ogg, you'll need to set your
*** LD_LIBRARY_PATH environment variable, or edit /etc/ld.so.conf to point
*** to the installed location Also, make sure you have run ldconfig if that
*** is required on your system
***
*** If you have an old version installed, it is best to remove it, although
*** you may also be able to get things to work by modifying LD_LIBRARY_PATH
configure: error: must have Ogg installed!
我们上面已经安装过libogg了，此时这个提示没有安装，可能是路径问题
解决方案，创建库文件
[root@restapi_1 libvorbis-1.3.4]# cat /etc/ld.so.conf.d/local-libraries.conf
/software/ffmpeg_build/lib
[root@restapi_1 libvorbis-1.3.4]# ldconfig -v
此时解决了库依赖问题，在次跑编译安装，没有报错了
LDFLAGS="-L/software/ffmeg_build/lib" CPPFLAGS="-I/software/ffmpeg_build/include" ./configure --prefix=/software/ffmpeg_build --with-ogg=/software/ffmpeg_build
make && make install

cd /software/ffmpeg_sources/libvpx
./configure --prefix="/software/ffmpeg_build" --enable-pic --enable-shared
make && make install

cd /software/ffmpeg_sources/ffmpeg3
PKG_CONFIG_PATH="/software/ffmpeg_build/lib/pkgconfig" ./configure --prefix="/software/ffmpeg_build" --extra-cflags="-I/software/ffmpeg_build/include" --extra-ldflags="-L/software/ffmpeg_build/lib" --bindir="/software/ffmpeg_build/bin" --pkg-config-flags="--static" --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265 --enable-pic --enable-shared --enable-gray --enable-avresample --enable-openssl
此时如果有编译报错，如下
/usr/bin/ld: /software/ffmpeg_build/lib/libx264.a(common.o): relocation R_X86_64_32 against `.rodata.str1.1' can not be used when making a shared object; recompile with -fPIC
/software/ffmpeg_build/lib/libx264.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make: *** [libavcodec/libavcodec.so.57] Error 1
解决方法是:
config.mak L75加入 -fPIC，然后重新编译
HOSTCFLAGS=-O3 -g -std=c99 -Wall -fPIC
我比较着急，直接去掉最后几个参数(询问开发，说不用这些模块)，开始搞
PKG_CONFIG_PATH="/software/ffmpeg_build/lib/pkgconfig" ./configure --prefix="/software/ffmpeg_build" --extra-cflags="-I/software/ffmpeg_build/include" --extra-ldflags="-L/software/ffmpeg_build/lib" --bindir="/software/ffmpeg_build/bin" --pkg-config-flags="--static" --enable-gpl --enable-nonfree --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libx265
然后不报错了，make && make install

安装完成后启动报错，发现是没有文件库
ffmpeg: error while loading shared libraries: libvpx.so.4: cannot open shared object file: No such file or directory
进入相关库查看
[root@zookeeper_rest-api-node1 ffmpeg3]# cd /usr/lib64
ls -l 查看后发现没有，于是从安装目录/software/ffmpeg_build/lib/libvpx.so.4找到这个文件，并做好软链接
[root@zookeeper_rest-api-node2 lib64]# ln -s /software/ffmpeg_build/lib/libvpx.so.4 /usr/lib64/libvpx.so.4
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ffmpeg -v
ffmpeg: error while loading shared libraries: libvpx.so.4: cannot open shared object file: No such file or directory
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ln -s /software/ffmpeg_build/lib/libvpx.so.4 /usr/lib64/libvpx.so.4
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ffmpeg -v
ffmpeg: error while loading shared libraries: libvorbisenc.so.2: cannot open shared object file: No such file or directory
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ln -s /software/ffmpeg_build/lib/libvorbisenc.so.2 /usr/lib64/libvorbisenc.so.2
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ffmpeg -v
ffmpeg: error while loading shared libraries: libvorbis.so.0: cannot open shared object file: No such file or directory
[root@iZ2zehjeved0zzfkdndbc5Z ffmpeg3]# ln -s /software/ffmpeg_build/lib/libvorbis.so.0 /usr/lib64/libvorbis.so.0

此时解决了问题，ffmpeg -v后如下图所示，没有报错
