Allowing direct file access for mpd

[manski]

On my installation "Ampache" and "mpd" are running on the same machine. So it would be nice to have a way to pass the local file paths of audio files to mpd (rather than a "play" URL); especially when Ampache is accessible from the internet. (In this the files are streamed from the local server to the internet and then back to the local machine; which might unnecessarily eat up bandwidth.)

One way to do this would be a new configuration variable (mpd_access) that controls the kind of path that is passed to mpd. The following code has to be inserted into the class AmpacheMpd (the ampache mpd controller):

/**
 * get_url
 * This returns the URL for the passed object
 */
public function get_url($object) {

  // This might not be an object!
  if (!is_object($object)) {
    // Stupiidly we'll just blindly add it for now
    return $object;
  }

  $url = null;

  // This can get a little complicated
  if (is_a($object, 'Random')) {
    // Do nothing
  } else if (is_a($object, 'Song') && Config::get('mpd_access') == 'local') {
    $url = $object->get_rel_path();
  } else {
    $url = $object->get_url(Stream::get_session());
  }

  return $url;
} // get_url

(Cross reference: ticket #294)

This solution is not very sophisticated, I know. A better way would be to allow the user to define this configuration variable seperate on each catalog.

This is how MPD used to work, this is undesirable as Ampache loses control of the playlist. Will not be implemented.
