“ffmpeg headers not found” error while installing ffmpeg in cPanel servers

Thu, 21 Aug 2008 21:08:36 +0000

The error received is

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 is due to missing header files in “/usr/local/include/ffmpeg” directory.

Check whether the directory “/usr/local/include/ffmpeg” exists else create it.

mkdir /usr/local/include/ffmpeg

The copy the header files.

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

You need to install your ffmpeg again. After installing the ffmpeg, install ffmpeg-php.

wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.1.2.tar.gz

3.Uncompress all the source files
bunzip2 essential-20061022.tar.bz2; tar xvf essential-20061022.tar
tar zxvf flvtool2_1.0.5_rc6.tgz
tar zxvf lame-3.97.tar.gz
bunzip2 ffmpeg-php-0.5.0.tbz2; tar xvf ffmpeg-php-0.5.0.tar
tar zxvf libogg-1.1.3.tar.gz
tar zxvf libvorbis-1.1.2.tar.gz

4.Create the new codecs directory and move the codecs
mkdir /usr/local/lib/codecs/
mv essential-20061022/* /usr/local/lib/codecs/
chmod -R 755 /usr/local/lib/codecs/

5.Install SVN and Ruby
yum install subversion
yum install ruby
yum install ncurses-devel

6.Download the latest FFMPEG and Mplayer from the subversion
svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer

7.Compile LAME
cd /usr/local/src/ffmpeg/lame-3.97
./configure
make
make install

8.Compile libOGG
cd /usr/local/src/ffmpeg/libogg-1.1.3
./configure
make
make install

9.Compile libVorbis
cd /usr/local/src/ffmpeg/libvorbis-1.1.2
./configure
make
make install

10.Compile flvtool2
cd /usr/local/src/ffmpeg/flvtool2_1.0.5_rc6
ruby setup.rb config
ruby setup.rb setup
ruby setup.rb install

11.Compile MPlayer
cd /usr/local/src/ffmpeg/mplayer
./configure
make
make install

12.Compile FFMPEG
cd /usr/local/src/ffmpeg/ffmpeg
./configure –enable-libmp3lame –enable-libogg –enable-libvorbis –disable-mmx
–enable-shared
echo ‘#define HAVE_LRINTF 1′ >> config.h
make
make install

13.Create symblinks
ln -s /usr/local/lib/libavformat.so.50 /usr/lib/libavformat.so.50
ln -s /usr/local/lib/libavcodec.so.51 /usr/lib/libavcodec.so.51
ln -s /usr/local/lib/libavutil.so.49 /usr/lib/libavutil.so.49
ln -s /usr/local/lib/libmp3lame.so.0 /usr/lib/libmp3lame.so.0
ln -s /usr/local/lib/libavformat.so.51 /usr/lib/libavformat.so.51

14.Compile FFMPEG-PHP
cd /usr/local/src/ffmpeg/ffmpeg-php-0.5.0
phpize
./configure
make
make install

15.Install FFMPEG-PHP (make sure the php.ini path is correct.)

Get correct php.ini path add the extesion ffmpeg.so Usually it is given as extension=ffmpeg.so and the extension_dir=/usr/local/lib/php/extensions/

Make sure that the ffmpeg.so is in /usr/local/lib/php/extensions/
echo ‘extension=/usr/local/lib/php/extensions/no-debug-non-zts-20020429/ffmpeg.so’>>
/usr/local/Zend/etc/php.ini

Or the best way is to check the path for extension_dir in php.ini Then locate the file ffmpeg.so. Copy the file ffmpeg.so to extension_dir and add the line
extension=ffmpeg.so

in php.ini

16.Restart Apache to load FFMPEG-PHP
service httpd restart

17.Verify the installation
php -r ‘phpinfo();’ | grep ffmpeg

If you get a few lines such as

ffmpeg
ffmpeg support (ffmpeg-php) => enabled
ffmpeg-php version => 0.5.0
ffmpeg.allow_persistent => 0 => 0

Then everything is installed and working. FFMPEG, FFMPEG-PHP, MPlayer, MEncoder, flv2tool, LAME MP3 encoder & libOGG.
