FFMpeg-PHP安装错误

Question

在安装FFmpeg-PHP时，我得到了一个有趣的错误：

当我运行php -r 'phpinfo();' | grep ffmpeg时，我得到了这个：

PHP Warning:  PHP Startup: Unable to
load dynamic library
'/usr/lib/php/modules/ffmpeg.so' -
libavformat.so.52: cannot open shared
object file: No such file or directory
in Unknown on line 0

知道我怎么能解决这个问题吗？我在Centos上跑。

(预先谢谢:)

Answer 1

为此：

PHP Warning:  PHP Startup: Unable to
load dynamic library
'/usr/lib/php/modules/ffmpeg.so' -
libavformat.so.52: cannot open shared
object file: No such file or directory
in Unknown on line 0

使用您需要的ffmpeg配置选项

--enable-shared

如果仍然有问题，请检查路径：

 export LD_LIBRARY_PATH=/usr/local/lib/
 echo /usr/local/lib > /etc/ld.so.conf.d/custom-libs.conf
 ldconfig

运行：

ldconfig

之后

make && make install

Answer 2

看起来你错过了libavformat库。您应该能够通过yum软件包管理器来安装它。

yum install ffmpeg

如果仍然无法工作，请尝试安装开发库。

yum install ffmpeg-devel

Answer 3

检查您的系统中的libavcodec/libavformat，它可能只是从库路径中丢失，或者您可能安装了与预期不同的版本。

find / -name 'libavformat*.so*' -print

如果您有libavformat.so.53，那么当您安装的ffmpeg被期望为.so.52时，就会出现问题。
