在Red Hat Enterprise Linux Server release 5.3 (Tikanga)环境下安装 FFMPEG 和 FFMPEG-PHP 。
[*]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
[*]这两个链接没用了 直接上官网下载吧：http://www.ffmpeg.orghttp://downloads.sourceforge.net/project/ffmpeg-php/ffmpeg-php
[*]安装ffmpeg1tar-xjf ffmpeg-export-snapshot.tar.bz2
2#进入解压后的源文件目录
3cdffmpeg-export-2010-03-02/
4./configure --prefix=/usr/local--enable-shared
5make
6makeinstall
测试是否能正常使用：
1# ffmpeg
2FFmpeg version SVN-r22144-snapshot, Copyright (c) 2000-2010 the FFmpeg developers
3built on Mar 30 2010 23:53:53 with gcc 4.1.2 20080704 (Red Hat 4.1.2-46)
4configuration: --prefix=/usr/local--enable-shared
5libavutil 50. 9. 0 / 50. 9. 0
6libavcodec 52.55. 0 / 52.55. 0
7libavformat 52.54. 0 / 52.54. 0
8libavdevice 52. 2. 0 / 52. 2. 0
9libswscale 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”
1vi/etc/ld.so.conf.d/ffmpeg.conf
2#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。
3ldconfig -v
[*]安装ffmpeg-php1tar-xjf ffmpeg-php-0.6.0.tbz2
2cdffmpeg-php-0.6.0
3/usr/local/php/bin/phpize
4./configure --with-php-config=/usr/local/php/bin/php-config --with-ffmpeg=/usr/local
5maketest
6make
7makeinstall
8#在php.ini中加入extension=ffmpeg.so
如果在make test中发现错误提示：make: *** Error 1
则：
1mvffmpeg_frame.loT ffmpeg_frame.lo
测试是否安装成功：
01php -r 'phpinfo();'| grepffmpeg
02ffmpeg
03ffmpeg-php version => 0.6.0-svn
04ffmpeg-php built on => Mar 31 2010 14:17:14
05ffmpeg-php gd support => enabled
06ffmpeg libavcodec version => Lavc52.55.0
07ffmpeg libavformat version => Lavf52.54.0
08ffmpeg swscaler version => SwS0.10.0
09ffmpeg.allow_persistent => 0 => 0
10ffmpeg.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
1nm /usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so|grepregister_ffmpeg_frame_class
2#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。
1viffmpeg_frame.c
2:%s/PIX_FMT_RGBA32/PIX_FMT_RGB32
3:w
4:q!
5./configure --with-php-config=/usr/local/php/bin/php-config --with-ffmpeg=/usr/local
