In case you receive an error as:

checking for ffmpeg support… yes, shared checking for ffmpeg headers… configure: error: ffmpeg headers not found. Make sure you’ve built ffmpeg as shared libs using the –enable-shared option 

This error is generally due to some header files not located in “/usr/local/include/ffmpeg” directory.

Can be fixed by doing the following:

First, check whether “/usr/local/include/ffmpeg” directory is created while installing ffmpeg. If not, create this directory by:

mkdir /usr/local/include/ffmpeg

Now copy the necessary ffmpeg header files to “/usr/local/include/ffmpeg”

cp -p /usr/local/src/ffmpeg/libavformat/avio.h /usr/local/include/ffmpeg
cp -p /usr/local/src/ffmpeg/libavformat/avformat.h /usr/local/include/ffmpeg
cp -p /usr/local/src/ffmpeg/libavcodec/avcodec.h /usr/local/include/ffmpeg

Once you have done this you need to install your ffmpeg package again. Later, install ffmpeg-php.
