YouTube: download 1080p videos when CLive is unavailable

Today's addition to the tips series has a funny history. A friend of mine was stuck in an envrionment, where she couldn't install Perl or CLive but PHP with some PECL modules was installed. She needed to download a few videos for a presentation, but didn't know how to fetch the videos from YouTube. So I was asked to help. ;-)

After some pondering of the problem, I came up with the following script:

 * Small little script to help out in the absence of Perl/Clive but with
 * PHP present.
 * License: GPLv3 

if(php_sapi_name() !== 'cli')
  die("This script needs to be run on the CLI!\n");

if($argc !== 2 )
  die("No URL given on CLI or too much parameters!\n");

// Script expects a URL like http://www.youtube.com/watch?v=[ID]
if(filter_var($argv[1], FILTER_VALIDATE_URL, FILTER_FLAG_QUERY_REQUIRED) === false)
  die("Parameter given as URL does not seem to be an URL or contain a query!\n");

if(!$ch = curl_init($argv[1]))
  die("Couldn't init cURL handle for »".$argv[1]."«\n");
curl_setopt($ch, CURLOPT_HEADER,          false );
curl_setopt($ch, CURLOPT_RETURNTRANSFER,  true  );
$htmlsource = curl_exec($ch);
$error = curl_error($ch);
if($htmlsource === false)
  die('cURL returned an error: '.$error."\n");

               $htmlsource, $matches))
  die("No matches found for url_encoded_fmt_stream_map!\n");

$final = NULL;
foreach(explode(',', urldecode($matches[1])) as $decoded_url_map) {
  parse_str($decoded_url_map, $tmp);
  if($tmp['quality'] === 'hd1080') {
    $final = $tmp;
    $final['url']   = urldecode($tmp['url']);
    // $final['type']  = urldecode($tmp['type']); // Not used
    break;  // Not really needed, but should save us some
            // iterations, since 1080p seems to come always first.

if(!is_array($final) || is_null($final))
  die("No 1080p version of the video was found!\n");


You can download it from my website or you can just copy the code given above into a file. No matter how you obtain the code, the invocation will look like: php -f /path/to/script.php http://www.youtube.com/watch?v=[ID].

Now, before I get a lot of e-mails telling me, what could be improved on the script or its other limitations (like only being able to download 1080p videos), please remember that it was hacked together for a simple use case with no real intent on my part to use it for anything else. It only later occurred to me, that others might be in a similar pinch sometime. Thus I'm releasing the above code "as is" under the GNU GPLv3. Therefore you're free to adapt it to your needs. Please also note, that I'm not recommending using the above script instead of CLive. If you can install CLive, do so and don't bother with the above.

wine-unstable: partly broken on amd64

Just a short entry, as I've already got a few e-mails about this: the JPEG is broken at the moment for my unofficial wine-unstable packages on amd64. This is due to #638543 in ia32-libs-dev. Please see the bug report for a detailed explanation.

A rebuild with libjpeg62-dev isn't an option, as other build dependencies pull libjpeg8-dev in anyway. Thus forcing the older version on amd64 just generates a FTBFS.

Full multi-arch support in the toolchain (including dpkg) or an update for ia32-libs are the two viable solutions for this as far as I can tell.
