The error message “Unable to load dynamic library ‘\/usr\/lib64\/php\/modules\/ffmpeg.so”<\/strong> is received when you add the ffmpeg.so extension to the PHP configuration file i.e. php.ini file and tries to run PHP. You can easily reproduce the error message by executing “php -v”:<\/p>\n

PHP Warning:\u00a0 PHP Startup: Unable to load dynamic library ‘\/usr\/lib64\/php\/modules\/ffmpeg.so’ – \/usr\/lib64\/php\/modules\/ffmpeg.so: undefined symbol: _php_create_ffmpeg_frame in Unknown on line 0<\/strong><\/span><\/p><\/blockquote>\n

You may also notice the “PIX_FMT_RGBA32” error message while compiling ffmpeg-php<\/p>\n

ffmpeg-php-0.5.0\/ffmpeg_frame.c:495: error: \u2018PIX_FMT_RGBA32\u2032 undeclared (first use in this function)<\/strong><\/span><\/p><\/blockquote>\n

The above error messages is the result of incorrect function declared in the ffmpeg_frame.c file<\/strong> under the ffmpeg-php-0.x.0 directory.<\/p>\n

Solution:<\/strong><\/span><\/p>\n

Goto the the ffmpeg-php-0.x.0 directory and edit the ffmpeg_frame.c file<\/p>\n

vi ffmpeg-php-0.x.0\/ffmpeg_frame.c<\/strong><\/span><\/p><\/blockquote>\n

Now replace every instance of ‘PIX_FMT_RGBA32’ with ‘PIX_FMT_RGB32’ in the file by executing<\/p>\n

:%s\/PIX_FMT_RGBA32\/PIX_FMT_RGB32<\/strong><\/span><\/p><\/blockquote>\n

OR<\/strong><\/p>\n

replace “PIX_FMT_RGBA32” “PIX_FMT_RGB32” — ffmpeg_frame.c<\/strong><\/span>
\n<\/strong><\/span><\/p><\/blockquote>\n

Save the file and compile ‘ffmpeg-php’ again using the following steps<\/p>\n

cd ffmpeg-php-0.x.0
\nmake clean
\n.\/configure
\nmake
\nmake install<\/strong><\/span><\/p><\/blockquote>\n

Once done, ffmpeg should work along with PHP now.<\/p>\n","protected":false},"excerpt":{"rendered":"
