Hi

This is my first post so i hope its in the right area.

I have a centos 5.8 installation and have installed ffmpeg but am getting errors when trying to run it.

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

I am not sure where to go with this now. I have been browsing the web for days and tried various different how tos?

Please help.

regards

Try to find the module that it's complaining about.

If it can find it and it's not in the location specified in the error, copy it or create a symlink to that location. If find doesn't find anything, then the module isn't installed.

HI

Can i simply copy the .so from somewhere else and put it in the location its looking for?

thanks

How did you install ffmpeg? From your package mgr? Or did you compile it yourself?
Sounds like a bad install of ffmpeg perhaps.
Also don't know why it's looking there. Are you using this as part of a script?

Post the command that you are using when you get that error.

I used an online how to using yum.

Cant remeber which one as there are quite a few.

I an running a cron job which converts video files.

Yes, you'll just need to find where the .so file is located.

If that file isnt on my server can i download it from somewhere?

I think I'm piecing together everything you've done. I'm assuming you installed ffmpeg and ffmpeg-devel using yum, but didn't build the extension. The ffmpeg.so file is actually a PHP module that needs to be built. Once you build the extension you should be able to find the ffmpeg.so file and copy it or symlink it to where ever it needs to be.

Here's how to do it if you need the steps.

Download the tarball

Go to the folder where the tarball downloaded and run the following commands:

You should be fine after that.

Ive followed your instructions but when i get to phpize i get the error


Cannot find config.m4.
Make sure that you run '/usr/bin/phpize' in the top level source directory of the module

Sorry, I forgot a step. After you extract the tarball, you have to cd into the ffmpeg-php-0.6.0 directory. That's where the config.m4 file for ffmpeg is located.

Thanks.

I get a bit further now but when running make

i get the following error at the end.

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

There is also a couple of these:

/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: (Each undeclared identifier is reported only once
/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:336: error: for each function it appears in.)
/root/ffmpeg-php-0.6.0/ffmpeg_frame.c: In function'zim_ffmpeg_frame_ffmpeg_frame':
/root/ffmpeg-php-0.6.0/ffmpeg_frame.c:421: error: 'PIX_FMT_RGBA32' undeclared (first use in this function)

In the ffmpeg-php-0.6.0 directory, run:
Or you can edit the ffmpeg_frame.c file and remove the A.

FYI. You should never compile as root. You should compile as a user and then sudo on the install.

I think thats got it, thanks.

No errors when running my cron job.

Great to hear!
