centos编译ffmpeg

yum install -y automake autoconf libtool gcc gcc-c++ 


安装yasm，ffmpeg编译中为了提高编译速度，使用了汇编指令，于是需要使用这个工具。
wget
tar xzfv yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure --prefix="$HOME/ffmpeg_build" --bindir="$HOME/bin"
make
make install
export "PATH=$PATH:$HOME/bin" 


Install Aacenc
wget
tar xzvf vo-aacenc-0.1.2.tar.gz
cd vo-aacenc-0.1.2
./configure --prefix="$HOME/ffmpeg_build" --disable-shared
make
make install






 wget


tar -zxvf faac-1.28.tar.gz
 cd faac-1.28
./configure 
make
会出现
mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’
vim faac-1.28/common/mp4v2/mpeg4ip.h +123   
删除char *strcasestr(const char *haystack, const char *needle);


修改前：
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif


修改为：
#ifdef __cplusplus
extern "C" {
#endif


#ifdef __cplusplus
}
#endif
然后
make install


wget
tar zxvf lame-3.98.4.tar.gz
cd lame-3.98.4
