PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/ffmpeg.so'

While Installing FFMPEG, when I was installing ffmpeg-php, I got this warning and it didn't work any further.

PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/ffmpeg.so' - /usr/lib/php/modules/ffmpeg.so: undefined symbol: le_ffmpeg_frame in Unknown on line 0

Tried to find the solution but didn't get any help. So I ended up reinstalling with different changes and using different guides. Following changes helped:::

First of all get 0.6.0 version, i.e ffmpeg-php-0.6.0.

Now after download: use vi to edit the ffmpeg_frame.c and search and replace PIX_FMT_RGBA32 with PIX_FMT_RGB32

To do this run the following commands:

cd ../ffmpeg-php-0.6.0

vi ffmpeg_frame.c

Now run this command:

:%s/PIX_FMT_RGBA32/PIX_FMT_RGB32

Now run ./configure && make && make install

This should solve the problem. Worked for me.
