Media app : all songs listed as "unknown artist"

[MorrisJobke]

Hi,

Since I updated my owncloud installation from 5.0.0 to 5.0.2 (or .3, I don't remember !), all the music I have in my music collection is listed as an unknown artist. My 811 tracks are now just in a single list by artist "unknown", ordered by song title.
Previously the media app worked well but now is no longer usefull anymore.
My entire music library is made of OGG files.

Is there some cache I have to clear somewhere ?

Hope someone finds a solution.

I am facing the same issue after upgrading from 5.0.5 (my initial install) to 5.0.6, however all my files are mp3. I tried clearing oc_media_albums in the sqlite database and rescanning the library but it did not fix the issue. After upgrading, I only found a couple of messages

{"app":"search_lucene","message":"need mimetype for content extraction","level":3,"time":1368657223}

in owncloud.log, which occurred before the update anyway, and no other error messages.

Are you running 32bit OS?
owncloud/core#3084
owncloud-archive/apps#963

Yes sorry, I forgot to reapply the fix for the size limit. Problem solved, thank you @VicDeo!

Thanks for your comments and the link to the issues #3084 and #963 . I applied the patch but unfortunately there are still 567 music files listed as "unknown" after refreshing the music collection. Is there a cache or a table I should clear to get everything work correctly ?

hi.
i have a small workaround for the shared music and the files listed as "unknown" issues.
this is dirty, and will be just for using local storages.

make the following changes:

1. owncloud\3rdparty\getid3.php

   // Check whether file is larger than 2GB and thus not supported by 32-bit PHP (null: auto-detect based on PHP_INT_MAX)
   public $option_max_2gb_check     = false;
   

2. owncloud\apps\media\lib\extractor.php (workaround over oc-protocoll bug?)

    public function extract($path) {
            $absolutePath = \OC\Files\Filesystem::getView()->getAbsolutePath($path);
            $absolutePath = \OC\Files\Filesystem::normalizePath($absolutePath);

            list($storage, $internalPath) = \OC\Files\Filesystem::resolvePath($absolutePath);
            $file = $storage->getLocalFile($internalPath);//let's get the phys. path
            $data = @$this->getID3->analyze($file);

            \getid3_lib::CopyTagsToComments($data);
        return $data;
    }

1. owncloud\apps\media\lib\scanner.php (add shared music)

    /**
     * get a list of all music files of the user
     *
     * @return array
     */
    public function getMusic() {
        $music = \OC\Files\Filesystem::searchByMime('audio');
        $ogg = \OC\Files\Filesystem::searchByMime('application/ogg');
        $shared = $this->getSharedMusic("//Shared");
        $music = array_merge($music, $ogg, $shared);
        //$music = array_merge($music, $ogg);
        foreach ($music as &$file) {
            $file = $file['path'];
        }
        return $music;
    }
    /**
     * get a list of all shared music files 
     * @param path to Shared Folder $sharedFolder
     * @return array
     */
    public function getSharedMusic($sharedFolderPath) {
            $sharedFolder = \OC\Files\Filesystem::getDirectoryContent($sharedFolderPath);
            $files = array();
            $this->getSharedMusicREK($sharedFolder,$sharedFolderPath,$files);
            return $files;
    }

    /**
     *  helper function for getSharedMusic
     *
     * @return void
     */
        private function getSharedMusicREK($array,$path,&$files) {
            foreach($array as $key => $value) {
                if($value["mimepart"] == 'audio') {
                    $value["path"] = $path."/".$value["name"];
                    $files[] = $value;
                } elseif($value["type"] == 'dir') {
                    $this->getSharedMusicREK(\OC\Files\Filesystem::getDirectoryContent($path."/".$value["name"]),$path."/".$value["name"],$files);
                }
            }
        }

i hope this bugs will be fixed soon ;).
good luck guys
