centos ubuntu 安装 ffmpeg php-ffmpeg
最近在做一个视频网站安装本地环境费了不少时间。本地是 ubuntu 9.10 而服务器是redhat as4 所以到时候本人会把服务器安装过程和大家分享出来。
本人环境如下
- php ―- 5.210
- apache 2.2
- ubuntu 9.10
- ffmpeg 功能很强大包括视频抓图，视频信息，视频转换，在线视频录制，而且是免费的。所有一般的视频网站都会采用他。
- 本人首先是采用编译安装，但是一直都没有成功。编译过程中出现了很多问题。安装要使用ffmpeg往往需要编译很多包。感觉很麻烦。这些包又依赖于很多其他包。安装顺序也有要求。所以放弃了。
- 最终采用ubuntu 强大的 apt-get (使用dpkg进行安装) 进行安装（当然cenos,red hat这类使用rpm的系统都可以使用yum进行安装,具体的安装方法可以在本站进行查找）.
- apt-get 安装步骤如下:
sudo apt-get update ##更新以下源
sudo apt-get install ffmpeg
sudo apt-get install php5-ffmpeg
sudo apt-get install mencoder
sudo apt-get install flvtool2 ##视频转换flv
sudo apt-get install lame ##音频
sudo apt-get install yasm - 编译安装ffmpeg 如下:
从 http://ffmpeg.mplayerhq.hu 下载
./configure �Chelp ##查看有那些参数
./configure�Cprefix=/usr�Cenable-gpl�Cenable-shared�Cenable-libmp3lame�Cenable-libamr_nb�Cenable-libogg�Cenable-libvorbis�Cenable-libxvid�Cenable-liba52�Cenable-liba52bin�Cenable-pp�Cenable-libfaad�Cenable-libfaadbin�Cenable-libfaac�Cenable-pthreads�Cdisable-ffserver�Cenable-x11grab
如果报错则安装该包，或者直接去掉该参数，只需要配置自己使用过程中需要使用到的就行了。
make & make install
其他的则一个一个的下载解压在编译就是了。 - 具体参考本文：centos+zendce+red5+ffmpeg安装配置
- 下面是php-ffmpeg 使用的api。功能是很少了。
- 如果需要给视频抓图择需要使用shell脚本。也就是用到php当中的(system,exec,passthru)这类执行外部命令函数。
往往很多服务器都将种类函数视为危险函数屏蔽掉了。所以想做视频网站对服务器的配置要求比较高。
当然最好是自己的独立服务器。vps 也可以。随便你怎么整都可以。

测试用例： ffmpeg-execute.php
安装过程出现错误解决:
- make: *** [ffmpeg-php.lo] Error 1
解决:.编译时加上 （php-config）路径：
--with-php-config=/usr/local/php/bin/php-config - make: *** [ffmpeg_frame.lo] Error 1
解决:mv ffmpeg_frame.loT ffmpeg_frame.lo - 其他问题请检查自己的php版本。和php-ffmpeg是否一致。
