Some codecs for music hosting services

Well, I tried to use emfield's "eminline" submodule first to achieve what I wanted. However, I soon found out that eminline only supports video embedding, even though emfield also has support for audio services. That made it useless for what I wanted to achieve.

First I considered extending eminline to also support audio services, but that seemed very challenging (I'm a newbie when it comes to Drupal module development), and something else I didn't like about eminline was that it extracts all URLs, i.e. not just the ones wrapped in some tag. That makes it impossible to link media instead of embedding.

The Video Filter module turned out to be a perfect fit, because of its easy extensibility. I whipped up most of the code in an evening.

I'm not arguing that you should include my code in the module (in fact I would argue against it, as it's way too half-assed for that), but I thought I would share it nevertheless in case someone else wants to achieve something similar. I think renaming 'Video Filter' to 'Media Filter' at some point wouldn't be a bad idea though ;)

I agree that duplicate work should be avoided, but it seems that eminline is mostly neglected by the emfield developers. So I was happy to find that this module exists :) I haven't looked into Drupal 7's Media module yet as I'm sticking with Drupal 6 for the time being.

Yeah, Bandcamp changed their HTML at some point. Here's the code I'm currently using. Should work for albums as well as individual tracks :)

  $codecs['bandcamp'] = array(
    'name' => t('Bandcamp'),
    'sample_url' => 'http://bandname.bandcamp.com/track/trackname',
    'callback' => 'video_filter_bandcamp',
    'regexp' => '@((?:\w+)\.bandcamp\.com/(?:[^"\&]*))@i',
    'ratio' => 400 / 100,
  );


function video_filter_bandcamp($video) {
  // based on the 'Media: Bandcamp' module: http://drupal.org/project/media-bandcamp
 
  $response = drupal_http_request("http://" . $video['codec']['matches']['0']);
  if ($response->code == 200) {
    //extract 'album' or 'track' and unique numerical identifier
    // preg_match('@(?:video_src.+)(album|track)=([\d]+)@i', $response->data, &$matches); // old way, doesn't work anymore
    // match against: tralbum_param : { name : "album", value : 3782954029 },
    preg_match('@tralbum_param : { name : "(album|track)", value : ([\d]+) }@i', $response->data, &$matches);

    $type = $matches[1]; // 'album' or 'track'
    $code = $matches[2]; // the numerical identifier for the album or track
  }
  
  $width = 400;
  $height = 100;
