ffmpeg ffmpeg-php 安装及出错解决办法

在centos 5.4环境下安装 FFMPEG 和 FFMPEG-PHP 。

1. 下载ffmepg及ffmpeg-php
   wget http://www.ffmpeg.org/releases/ffmpeg-export-snapshot.tar.bz2
   wget http://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php/0.6.0/ffmpeg-php-0.6.0.tbz2?use_mirror=ncu
2. 安装ffmpeg

   tar -xjf ffmpeg-export-snapshot.tar.bz2
   #进入解压后的源文件目录
   cd ffmpeg-export-2010-03-02/
   ./configure --prefix=/usr/local   --enable-shared
   make
   make install

   测试是否能正常使用：

   [root@mail ffmpeg-export-2010-03-02]# ffmpeg
   FFmpeg version SVN-r22144-snapshot, Copyright (c) 2000-2010 the FFmpeg developers
     built on Mar 30 2010 23:53:53 with gcc 4.1.2 20080704 (Red Hat 4.1.2-46)
     configuration: --prefix=/usr/local --enable-shared
     libavutil     50. 9. 0 / 50. 9. 0
     libavcodec    52.55. 0 / 52.55. 0
     libavformat   52.54. 0 / 52.54. 0
     libavdevice   52. 2. 0 / 52. 2. 0
     libswscale     0.10. 0 /  0.10. 0

   如果提示：“ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory”

   vi /etc/ld.so.conf.d/ffmpeg.conf
   #在里面加入：usr/local/lib，这个目录，为ffmpeg安装后libavdevice.so.52等lib文件所在目录。
   ldconfig -v

3. 安装ffmpeg-php

   tar -xjf ffmpeg-php-0.6.0.tbz2
   cd ffmpeg-php-0.6.0
   /usr/local/php/bin/phpize
   ./configure --with-php-config=/usr/local/php/bin/php-config  --with-ffmpeg=/usr/local
   make test
   make
   make install
   #在php.ini中加入extension=ffmpeg.so

   如果在make test中发现错误提示：make: *** [ffmpeg_frame.lo] Error 1
   则：

   mv ffmpeg_frame.loT ffmpeg_frame.lo

   测试是否安装成功：

   php -r 'phpinfo();' | grep ffmpeg
   ffmpeg
   ffmpeg-php version => 0.6.0-svn
   ffmpeg-php built on => Mar 31 2010 14:17:14
   ffmpeg-php gd support  => enabled
   ffmpeg libavcodec version => Lavc52.55.0
   ffmpeg libavformat version => Lavf52.54.0
   ffmpeg swscaler version => SwS0.10.0
   ffmpeg.allow_persistent => 0 => 0
   ffmpeg.show_warnings => 0 => 0

   如果有ffmepg-php模块错误提示：php: symbol lookup error: /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so: undefined symbol: register_ffmpeg_frame_class

   nm /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so|grep register_ffmpeg_frame_class
   #输出U register_ffmpeg_frame_class
   

   则修改ffmpeg_frame.c,将3处的PIX_FMT_RGBA32 更改为PIX_FMT_RGB32即可。

   vi ffmpeg_frame.c
   :%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
   :w
   :q!
   ./configure --with-php-config=/usr/local/php/bin/php-config  --with-ffmpeg=/usr/local
   make test
   make
   make install
