#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 --disable-yasm --enable-libx264  --enable-gpl  --prefix=/home/jiajia/ffmpeg-x64
make
make install
 

./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
