安装yasm，一般这个 yum 仓库会有这个包，可以直接安装
| 1 | yum install yasm |
安装ffmpeg
svn checkout svn://svn.ffmpeg.org/ffmpeg/trunk ffmpegcd ffmpeg/./configure --prefix=/usr/local/ffmpeg --enable-sharedmakemake install |
可以使用ffmpeg命令查看是否安装成功：
成功会返回如下信息

我在安装的时候出现了报错：
ffmpeg: error while loading shared libraries: libavdevice.so.52 : cannot open shared object file: No such file or directory解决方法：在 /etc/ld.so.conf 中最后一行添加你的ffmpeg的安装目录，并确保安装目录下有此文件 lib/libavdevice.so.52在运行 ldconfig 重新加载信息 |
下面安装php-ffmpeg
下载地址：http://ffmpeg-php.sourceforge.net/
版本为：ffmpeg-php-0.6.0.tbz2
支持的最低版本：
ffmpeg-0.4.9_pre1 or higher.
php-4.3.0 or higher
gd-2.0 or higher (the version of GD bundled with PHP works too)
如果没有 phpize ，则需要安装 php-devel
tar xjf ffmpeg-php-0.6.0.tbz2cd ffmpeg-php-0.6.0/phpize./configure --with-ffmpeg=/usr/local/ffmpeg可以先使用make test查看是否有报错然后在使用make clean 重新编译makemake install |
在安装 php-ffmpeg 出现如下报错
/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: (Each undeclared identifier is reported only once/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: for each function it appears in.)/root/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function ‘zim_ffmpeg_frame_ffmpeg_frame’:/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:421: error: ‘PIX_FMT_RGBA32’ undeclared (first use in this function)make: *** [ffmpeg_frame.lo] Error 1/root/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function ‘zim_ffmpeg_frame_toGDImage’: |
需要将 ffmpeg_frame.c 里面的 PIX_FMT_RGBA32 替换为 PIX_FMT_RGB32，总共有三处
所有编译服务安装完成之后，需要在 php.ini 中最后一行加入：extension=ffmpeg.so
重启 php 使生效
使用下面方式可以查看是否生效：
php -m|grep ffmpegphp -r 'phpinfo();' | grep ffmpeg |
