ffmpeg.so unable to load dynamic library

jonn · Apr 26, 2009

if anyone has installed FFmpeg + FFmpeg-PHP + Mplayer + Mencoder + flv2tool + LAME MP3 Encoder + Libogg + Libvorbis + AMR on a Linux Based Server

please Im going insane this is the second day on this install, I followed about 13-20 different sites instructions, google groups, and finally it installed

BUT. and a big BUT

These are the files I used to install after many many different tries with many different versions to get it to install.

Code:

Setup the directory to use
(Wouldn’t want /root to start getting crowded, would we?)
mkdir /usr/local/src
cd /usr/local/src

Dowload the necessary files.
wget http://www3.mplayerhq.hu/MPlayer/releases/codecs/essential-20061022.tar.bz2
wget http://rubyforge.org/frs/download.php/9225/flvtool2_1.0.5_rc6.tgz
wget http://easynews.dl.sourceforge.net/sourceforge/lame/lame-3.97.tar.gz
wget http://internap.dl.sourceforge.net/sourceforge/ffmpeg-php/ffmpeg-php-0.5.1.tbz2
wget http://downloads.xiph.org/releases/ogg/libogg-1.1.3.tar.gz
wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.1.2.tar.gz
wget http://ftp.penguin.cz/pub/users/utx/amr/amrnb-6.1.0.4.tar.bz2
wget http://ftp.penguin.cz/pub/users/utx/amr/amrwb-6.0.0.1.tar.bz2

It installed I was so happy, but I think I celebrated too early.

=============////

when trying the make test to see if it worked

[root@ns1 ffmpeg-php-0.5.1]# make test

I got errors -- it doesnt load the ffmpeg.so

Code:

[root@ns1 modules]# cd /usr/local/src/ffmpeg-php-0.5.1/
[root@ns1 ffmpeg-php-0.5.1]# make test

Build complete.
Don't forget to run 'make test'.

now I know it's there because I see it in:
/usr/local/lib/php/extensions/no-debug-non-zts-20060613/

and everywhere else:
ffmpeg: /usr/bin/ffmpeg /usr/local/bin/ffmpeg /usr/share/ffmpeg

Any help is greatful.
Ive looked at many websites over 2 days. And every page here on directadmin, nothing helped all are outdated by nearly 2 years or for another OS, I still get the error regardless what I try.

I tried removing ./ in extension_dir=""
I also tried extension_dir="/usr/local/lib/php/extensions/no-debug-non-zts-20060613/"
in both Zend/php.ini & lib/php.ini
with & without extension=ffmpeg.so
added it in many variations, then removed the changes to php.ini's I did and tried 'make test' and again the same error with ffmpeg.so. It didnt matter what I tried.

What Am I missing. I know it's a stab in the dark asking.
The server is custombuild CLI 32bit. If that helps understand what I rambling on about.

nah got a lot of errors.

make: *** [ffmpeg_frame.lo] Error 1

So I looked inside the folder /root/ffmpeg-php-0.5.3.1/ to find the spelling error is still there. so I typed:

Code:

cp ffmpeg_frame.loT ffmpeg_frame.lo

Now make worked, then make install, installed okay to:

Code:

Installing shared extensions:     /usr/local/lib/php/extensions/no-debug-non-zts-20060613/

I did the cp ffmpeg to php.ini and tried make test and it spat out:

Code:

jonn · Apr 27, 2009

I got the ffmpeg to convert. Finally...

So for anyone else having to install FFMPEG
Use floyd example, to load only the ffmpeg stuff in the yum statement he noted:
I wish I new earlier.

My system is:
Red Hat 9
CentOS 5
CLI Custombuild
PHP 5.2.9

to make my software identify the video in /usr/local/bin/ffmpeg
I moved the ffmpeg.so to the lib directory, rebuild php restarted and wallah.
funny enough before i rebuild php it didnt load, so something in php got screwed up.

Code:

cp /root/ffmpeg-php-0.5.3.1/modules/ffmpeg.so /usr/local/lib/

I used this to test ffmpeg is working.

Code:

<html>
<head>
<title></title>
</head>
<body>
<h1>FFMPEG Video Plugin Server Test</h1>
<?
if(!isset($_GET['ffmpeg_path'])) { // show form
if(in_array('exec', explode(',', ini_get('disable_functions')))) {

<br><br>Please enable this function by editing the "disable_functions" variable in your php.ini file';
exit; }
$ffmpeg_path = '';
$error = false;
} else { // verify that ffmpeg is installed
$ffmpeg_path = escapeshellcmd(strip_tags($_GET['ffmpeg_path']));
$error = false;
$result = null;
exec($ffmpeg_path.' -version', $result);
if(empty($result) || !isset($result[0]) || !strstr($result[0], 'FFmpeg')) {
$error = true; } else { echo 'Your server has got all video plugin requirements.';
exit;}}
?>

<? } ?>
<br><br>
<input type="submit" value="Find FFmpeg installation">

</html>

anyway it now works, thanks to floyd and the sample install alternative. Well done.

Glad you got it working.

You cannot have both RedHat9 and CentOS 5

My example will probably work ok if you have not already tried it the other way. I have done this on dozens of servers now without a glitch.

jonn · Apr 29, 2009

Appreciate it, but for that one I would say a big "woops", no doubt they are two different operating systems. I clicked copy'n'paste from a textpad, didnt pay attention to the part I clicked copy. should have typed it.

Do I still get an A for effort.

iFusion · May 9, 2009

i have err0r

Code:

[root@trance ~]# php -r 'phpinfo();' | grep ffmpeg
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/local/lib/php/extensions/no-debug-non-zts-20060613/ffmpeg.so' - /usr/lib/libavcodec.so.51: undefined symbol: av_crc04C11DB7 in Unknown on line 0
[root@trance ~]#

how i can fix this

Thank you.

sligh · May 10, 2009

iFusion,

Did you create the library symlinks?

Code:

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

You can also try updating your shared libraries.

Code:

ldconfig -v

Good luck,
Ted

sligh · Jun 19, 2009

iFusion,

How did you go about your install, RPMs or Source? Did you gather instructions from somewhere, if so, where? I have a crude bash script I threw together as I have performed installs on a number of Redhat based OSes... saves me loads of time.

If your interested PM me.

Hello,

I have this problem:

Code:

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

My system is:
VPS with Centos 5.2
PHP 5.2.10 (cli) (built: Aug 1 2009 11:00:52)

Can anybody help me?

Thank you.

Solved

I was getting the following error too:::

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

Found the solution here along with the guide for installing ffmpeg

hosaya · Jul 9, 2010

I solved this problem by changing the extension_dir in php.ini to the real directory.

#
#
; Directory in which the loadable extensions (modules) reside.
extension_dir = "/usr/local/lib/php/extensions/no-debug-non-zts-20060613/"
I wish it would help
