Hello Guys, i hope you can help me, i'm using youtube-dl since 1 year. I wanna try to parse the flv url trow php now.

$yt_video_id = "ID";
$check_status = curl_init('http://www.youtube.com/get_video_info?video_id='.$yt_video_id.'&fmt=18');
curl_setopt($check_status, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($check_status, CURLOPT_RETURNTRANSFER, true);
$get_youtube_src = curl_exec($check_status);
curl_close($check_status);

if (eregi('url_encoded_fmt_stream_map',$get_youtube_src))
{
$vidUrl = end(explode('url_encoded_fmt_stream_map=',$get_youtube_src));
$vidUrl = urldecode(urldecode(current(explode('&',$vidUrl))));
$vidUrl = current(explode(';',$vidUrl));
$vidUrl = urldecode(end(explode('url=',$vidUrl)));
$complete = $vidUrl;

echo "complete";

The $complete should be the Download Url, but sometimes it isn't working. Can you tell me why? From 10 Videos, 8 isn't working 2 is working?

regards mike

It looks like you're not using youtube-dl at all, but writing a similar application in php. Therefore, this is not a valid bug report for youtube-dl. However, you're in luck: youtube-dl can print out the download URL you're currently calculating in php, with the -g option:

$ youtube-dl -g http://www.youtube.com/watch?v=uHlDtZ6Oc3s
http://v23.lscache1.c.youtube.com/videoplayback...

From php, you can use this functionality like this:

$complete = exec('youtube-dl ' . escapeshellarg($yturl));
if (!$complete) throw new Exception('Cannot download video');

If this fails for any youtube URLs, please file a new bug report, and include:

The URL
Your physical location (country or public IP)
The precise output of youtube-dl -g $url
The output of youtube-dl --version; md5sum $(which youtube-dl)
The output of python --version

Thanks!

This belongs in a stackoverflow question, not a youtube-dl bug report.
