[SOLVED] Thumbnail Generator Issue in 9.0.0

[philrandal]

I also have issues with tumbnails scanning and I don't know how to check/debug what the problem is. The scanning stops in a folder with mp3 files and I checked other files that were scanned before and have the thumbnail.

Here's one of the files that passed the scanning:

Code:

eyeD3 Bagpipes/Bagpipes\ 01\ -\ Inverness\ Gathering\ -\ Australian\ Ladies.mp3
/zet/Muzica/Andreea/Bagpipes/Bagpipes 01 - Inverness Gathering - Australian Ladies.mp3                                                                                          [ 2.02 MB ]

b'WXXX' [Description: ]:

I removed the WXXX frame and tried to rescan, but it still stops at the same folder. Then I checked and some of the files had "OTHER IMAGE", so I removed that too, but still no change. How can I see which file breaks  the process?

I'm on 9.0.0 on a RPi 4.

I renamed all the files in the folder but one and rescanned, until I hit the block.  In my case, it was the first file I chose.

Same issue here. Scanner stopped at 3 folders. Since those had been very old and in low quality I did not bother further and just deleted them.

I don't think this is a solution. Some of the albums I have in mp3 format may not be available anymore. Also, this didnt/doesn't happen with the older version of moode.

I had this issue on 2 installations, both sd cards, and because I had another issue I tried a usb stick, strangely thumbnail generation issue was gone.

I don't think this is a solution. Some of the albums I have in mp3 format may not be available anymore. Also, this didnt/doesn't happen with the older version of moode.

Can you just check if the issue happens on files that have "unpolite" characters in their name, such as ' (apostrophe) or & ?
Also. are you playing local files, or say, from a Windows shared folder in your computer...?

[Tim Curtis]

I don't think it's the file name. One failure case that was reported had to do with a URL in a tag.
The challenge is the time consuming process of tracing and debugging the Zend media code. Not trivial but if a dev want's to give it a try I can help out a bit.

FWIW I had this issue and it was a URL in the tag also. Deleted the URL and everything seems fine now.

Hi,

I also have problems with the Thumbnail generator in 9.0.0.

It stops scanning (without any error or warning message with debuging enabled) at a certain direcory. If I remove that directory (containing a single album) it scans until it finds another problem (and stops again). I have seen it stop on MP3 files and on FLAC files as well.

Is there a command I can run from the command line to see/verify success or failure scanning this particular directory?

It appears that if I add another ('good') MP3 file into the directory where the scanning halts, it continues... 
It even works if I add a JPG file into the offending directory...

Can I increase the debug level further, to see what the thumbnail generator is doing?

Could it be something else? I did not change anything and now it hangs on a directory it previously scanned properly.
My library is on an SMB share...
Nope: same issue when NFS mounting my library...

There are some logging statements commented out in /var/www/util/thm-gen.php that might provide more detail.

Look for lines like //workerLog(

Hi Tim,

It seems that this statement in thumb-gen.php (line 318) does not return:

$id3v2 = new Zend_Media_Id3v2($path, array('hash_only' => false)); // r44a

Code:

                case 'mp3':
                        require_once __DIR__ . '/../inc/Zend/Media/Id3v2.php';

                        try {
workerLog('thumb-gen: getImage(): 4 (path = ' . $path . ')');
                                $id3v2 = new Zend_Media_Id3v2($path, array('hash_only' => false)); // r44a
workerLog('thumb-gen: getImage(): 5');

                                if (isset($id3v2->apic)) {

The log prints:

Code:

20240528 201917 thumb-gen: getImage(): 4 (path = /var/lib/mpd/music/NAS/NFS/2/stevie wonder - (2001) vocals and instrumentals pt2 (lg100)/11 - for once in my life.mp3)

and then the thumbnail generator stops and I do not get debug output 'thumb-gen: getImage(): 5' anymore...

Now investigating Zend_Media_Id3v2 ...

Seems to fail in /var/www/inc/Zend/Media/Id3v2.php, line 213:

Code:

workerLog('Id3v2 Constructor: 18 classname = ' . $classname);
                $frame = new $classname($this->_reader, $options);
workerLog('Id3v2 Constructor: 19');

Log shows:

Code:

20240528 203325 Id3v2 Constructor: 18 classname = Zend_Media_Id3_Frame_Wcom

Would that be: '/var/www/inc/Zend/Media/Id3/Frame/Wcom.php' ? 
Wcom.php seems to refer to /var/www/inc/Zend/Media/Id3/LinkFrame.php. This file has another constructor. Here the thumbnail generator fails at line 56:

Code:

    public function __construct($reader = null, &$options = array())
    {
        parent::__construct($reader, $options);

workerLog('Zend_Media_Id3_LinkFrame: 1');
        if ($this->_reader !== null) {
workerLog('Zend_Media_Id3_LinkFrame: 2');
            $this->_link = implode
                ($this->_explodeString8
                 ($this->_reader->read($this->_reader->getSize()), 1), '');
        }
workerLog('Zend_Media_Id3_LinkFrame: 3');
    }

Log file shows that debug line '3' is never reached:

Code:

20240528 204059 Id3v2 Constructor: 18 classname = Zend_Media_Id3_Frame_Wcom
20240528 204059 Zend_Media_Id3_LinkFrame: 1
20240528 204059 Zend_Media_Id3_LinkFrame: 2

Seems that 'implode' crashes without any trace... Now its getting too complicated for me, I guess .
