#下载x264源码编译生成libx264.so库，重新编译FFmpeg并将x264添加进去
[root@VM-16-6-centos ~]# git clone https://code.videolan.org/videolan/x264.git
cd x264 //进入x264源码文件目录下
./configure --enable-shared
make
sudo make install
sudo cp /usr/local/lib/libx264.so.164 /lib //生成文件的默认路径为：/usr/local/lib
cd ffmpeg //进入ffmpeg源码文件目录下

./configure --enable-shared编译想264报错Found no assembler
Minimum version is nasm-2.13 处理方式如下
Linux下编译x264 If you really want to compile without asm, configure with --disable-asm 的解决办法 下载 nasm https://www.nasm.us/pub/nasm/releasebuilds/2.13.03/ 解压 tar -zxvf nasm-2.13.03.tar.gz 进入目录 cd nasm-2.13.03 安装即可 ./configure make make install 安装nasm之后再进入x264目录 ./configure
