[SOLVED] PHP can't find external binary, need debugging help

[3than]

I'm working with a drupal installation and the op_video module and am fairly new to PHP.  I installed ffmpeg here: /usr/bin/ffmpeg but the module says it can't find it there.  I suspect it's something to do with the way my server is configured, but I have both safe mode and open_basedir off.  Is there some code I can insert into the module to get a verbose error message that shows what's actually happening when it tries to find ffmpeg?  I want to know where it's actually looking for it, and what happens when it tries to access it.  I think I've quoted the relevant code below.

 

thanks

Ethan

 

	$output = array();
_op_video_ffmpeg_exec('-version', $output, $result);

if($result == 0) {
	$fieldset[] = _op_video_ffmpeg_version_info_fieldset($output);

	$output = array();
	_op_video_ffmpeg_exec('-formats', $output, $result);

	$fieldset[] = _op_video_ffmpeg_formats_fieldset($output);
	$fieldset[] = _op_video_ffmpeg_codecs_fieldset($output);
}
else {
	$fieldset[] = array(
		'#value' => '<p><b>' . t('FFmpeg binary not found.') . '</b></p>'
	);
}

Can I see this function's code?

_op_video_ffmpeg_exec()

i think i may know what your problem is.

 

run this command for me on your box: cat /etc/ld.so.conf

 

and tell me the output

Oh hey, I got quoted in your sig.    And have you seen this problem before?   Just curious.

_op_video_ffmpeg_exec()

 

function _op_video_ffmpeg_exec($params, &$output, &$result, $mode = 0) {

$ffmpeg = variable_get('op_video_ffmpeg_binary', OP_VIDEO_DEFAULT_FFMPEG_BINARY);
$extra_params = variable_get('op_video_ffmpeg_extra_params', '');

$command = array($ffmpeg, $params, $extra_params, '2>&1');

_op_video_exec($command, $output, $result, $mode);
_op_video_reset_cron();
}

I ran into it when I was configuring ffmpeg, actually

 

You have to add some things to your conf file for it to work, if it is the identical problem.

[Jabop]

run:

 

find / -name 'libavdevice.so.*'

 

add the directories that come up with results into that conf file, then run sudo ldconfig

[3than]

run:

 

find / -name 'libavdevice.so.*'

 

add the directories that come up with results into that conf file, then run sudo ldconfig

 

no results, just this:

 

find: WARNING: Hard link count is wrong for /proc/vz/vzaquota: this may be a bug in your filesystem driver.  Automatically turning on find's -noleaf option.  Earlier results may have failed to include directories that should have been searched.

I can run ffmpeg from the command line, it's just that the module says it can't find it.  Any suggestions for tracking what the module is actually doing?

OK here's another clue -- I set up a test.php file:

 

<?php
$ffmpeg = "/usr/bin/ffmpeg -version";
$out = @fopen('php://output', 'a') or die("Could not open STDOUT");
exec($ffmpeg);
echo $out;
?>

 

it works fine from the command line, I think:

wouldnt this need mysql_result() or mysql_fetch_array() to output anything???

I don't know -- I don't think there are any mysql calls required here?  I'm just trying to figure out why the call to ffmpeg isn't working.

[Jabop]

3than, try echo passthru("ffmpeg -v");

[3than]

3than, try echo passthru("ffmpeg -v");

 

works from the command line but yields a blank page via http

tried it with mysql --version instead and that worked, same result from command line and in the browser. hmmm.

[3than]

I reinstalled ffmpeg and the test pages work now.

[3than]

However, the module still doesn't work, and if I change the test page back to

 

<?php
$ffmpeg = "/usr/bin/ffmpeg -version";
$out = @fopen('php://output', 'a') or die("Could not open STDOUT");
exec($ffmpeg);
echo $out;
?>

 

I still get "Resource id #3" and the same result if I replace ffmpeg with mysql.

 

is there anything wrong with the test page as above?
