ffmpeg in virtual machine

corina.pelmus · 02-09-2010, 02:42 AM

Hi!

I try for some weeks now to install ffmpeg in a CentOS 3.9 VM. The configuration is successful, but when I try to complete the test I receive the error:
/usr/local/apache-2.0.63/bin/httpd: relocation error: /usr/local/apache-2.0.63/php5/ffmpeg.so: undefined symbol: av_picture_copy

I searched a lot regading this error, but I couldn't find any solutions.
Does anybody have any ideas?

Thanx!

Hi and welcome to LQ

How did you install ffmpeg and ffmpeg-php? I've always used sources from svn for both programs, and never had such problems.
You can also try this guide and see if it helps

Hello!
Thank you for the welcome wishes.

I installed the ffmpeg and the ffmpeg-php from sources, and the installation was successful.
I looked on the guide you suggested and is basically the same thing I did.

Same error:
/usr/local/apache-2.0.63/bin/httpd: relocation error: /usr/local/apache-2.0.63/php5/ffmpeg.so: undefined symbol: av_picture_copy

What versions of ffmpeg and ffmpeg-php have you used? av_picture_copy is defined in libavcodec, so I guess ffmpeg is not, let's say, compatible with ffmpeg-php.
You should get the latest sources from svn for both. For reference here are the options I've used to build ffmpeg:

Code:

./configure --enable-shared --enable-libvorbis --enable-gpl --enable-nonfree --enable-pthreads --enable-libfaac --enable-libfaad --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab

Of course you might not need all these options (at least the 3-4 last ones).
Remember to run "make distclean" before running ./configure

Hello!

Sorry for the delay.

I tried to configure ffmpeg as you pointed, but the last 5 options are rejected, and the make command shows the following error:

"# make
make: *** No rule to make target 'libadevice/libadevice.so' , needed by 'all'. Stop. "

I must mention again that i'm trying to install it on a Centos 3.9 machine.

Regards,
Corina

Hi,

The only important option if you want to build ffmpeg-php, is "--enable-shared". The others depend on the specific file formats you're going to deal with.
Anyway you should use the latest sources from svn for both programs. There is also a howto for Centos here.

Hi,

After recompiling, the 'make test' command output is:

=====================================================================

I believe that I need some more libraries, but I can't figure out which one.

I doesn't matter since it compiles successfully.
Run "make install" to install it and add the extension into php.ini. Then restart apache and test.

corina.pelmus · 02-16-2010, 02:42 AM

Ok, I made it work. It shows me the ffmpeg as a loaded function in php.

But the test still fails.

bathory · 02-16-2010, 03:09 AM

If you want to test the installation, follow the instructions on ffmpeg-php site:

Quote:

Testing the Installation

* Put the directory test_media and test_ffmpeg.php script under your web root somewhere (put both in the same directory).
* Load test_ffmpeg.php into your browser.

RESULTS: You should get a listing of the methods provided by the ffmpeg-php module as well as some test output from the methods.

Mind that you might need to change "<?" to "<?php" in the 1st line of test_ffmpeg.php

I already did that before:

The output is:

'/' . $file; if (!is_dir($fullpath) && $file != "CVS" && $file != "." && $file != "..") $filesArr[] = trim($fullpath); } closedir($handle); } return $filesArr; } ?>

Sorry, missed the php adding thing.

corina.pelmus · 02-16-2010, 03:14 AM

It works, and the output is the mentioned one.

Thank you!

But how can I test to see that a video works well for example?

When I load the run-tests.php in the browser I get:

Quote:

ERROR: environment variable TEST_PHP_EXECUTABLE must be set to specify PHP executable!

Don't bother with that. run-tests.php is used by "make test". If ffmpeg extension is loaded, then you're ok.

corina.pelmus · 02-16-2010, 05:26 AM

Ok, I understand.

Thank you very much!

Kind regards,

Hi again!

I tried to make a test using ffmpeg and the output is:
