i faced this problem while i was trying to use youtube-dl by php on ubuntu.
I am using XAMPP for Linux v1.8.3 (PHP 5.5.9)
The error i received after executing:
{"status":0,"errors":"Traceback (most recent call last): File \"/usr/bin/youtube-dl\", line 3, in import youtube_dl File \"/usr/lib/python2.7/dist-packages/youtube_dl/_init_.py\", line 65, in from .utils import ( File \"/usr/lib/python2.7/dist-packages/youtube_dl/utils.py\", line 18, in import ssl File \"/usr/lib/python2.7/ssl.py\", line 61, in import _ssl # if we can't import it, let the error propagate ImportError: /usr/lib/python2.7/lib-dynload/_ssl.x86_64-linux-gnu.so: symbol GENERAL_NAME_free, version OPENSSL_1.0.0 not defined in file libcrypto.so.1.0.0 with link time reference
And this is my php code
<?php
$url = 'https://www.youtube.com/watch?v=xFQFMSNZW08&list=RDV-jLo0Ovems';
//escapeshellarg
$string = ('youtube-dl --max-quality 2180 --write-thumbnail -x --audio-format mp3 -c -o "/home/bahaa/%(id)s.%(ext)s" https://www.youtube.com/watch?v=xFQFMSNZW08&list=RDV-jLo0Ovems');
$descriptorspec = array(
0 => array("pipe", "r"), // stdin
1 => array("pipe", "w"), // stdout
2 => array("pipe", "w"), // stderr
);
$process = proc_open($string, $descriptorspec, $pipes);
$stdout = stream_get_contents($pipes[1]);
fclose($pipes[1]);
$stderr = stream_get_contents($pipes[2]);
fclose($pipes[2]);
$ret = proc_close($process);
echo json_encode(
array(
'status' => $ret,
'errors' => str_replace(array('', "
"), "<br />", $stderr."<hr />"),
'output' => $stdout,
)
);
?>
Any help will be appreciated.
