As you had told me, exceptions that appear in error.log are normal.
But I wonder if it is normal for error.log file getting bigger everyday because of this.
I see everyday exceptions like these:

To figure out which tracks this might be, you might open that media library within a new and empty playlist and see which tracks are 'not playable'.

Bernd this is something I can not do because this is a library containing more than 50000 entries.
How can I test so many tracks if are playable or not ?

Hmm, then I need to provide some more details in my logs to tell you which file (data) is causing the error...

Posted: **06 Oct 2014 20:34**

No, this is not what I told you. Exceptions in the "Error.log" file are never normal !
I once told you, that a very specific exception in the debug log file (you send me) can actually happen and was no reason to worry about.
This doesn't mean, that all errors in the "Error.log" file are normal - note, that the debug log and the Error.log are totally different things.
So each exception is subject to investigation...

The errors you are showing here seems to be from an error when parsing a result from the remote media lib "Ελληνικά".
It is hard to say what exact error it is, but it is clear, that the data returned from the Media Library Server leads to an error - meaning the track is not recognized.
As such, some tracks in that "Ελληνικά" media lib are corrupt, do have invalid meta data etc.

To figure out which tracks this might be, you might open that media library within a new and empty playlist and see which tracks are 'not playable'.
Once you figured one or two, please send them over to me to take a look.

After sending me some test files we figured the following:

Various files contained 'a lot of garbage' at the beginning of the file (after the TAGs).
ProppFrexx finally played those files fine with a verification size of 96KB (see below).

Some files where encoded using a nonstandard, proprietary MPEG 2.5, Layer I format.
This format is not supported (as it is proprietary).

Some files are missing a mandatory MP3 frame (which includes among other things the duration and total number of frames).

All files (for which the above exception is reported) might been seen as incorrect MP3 files - as such it is good to have this indication!

Some encoders or taggers might have been used with those files which have added invalid or incorrect MP3 frames (garbage) to the beginning of these files!

Notes:
The audio lib I am using (BASS) determines the file format to use by analyzing the file content.
The amount of data to check in order to verify/detect the file format can be adjusted in the general settings (see General/Audio - File Verification Size).
E.g. increasing this value to e.g. 96KB made the file 1. and 2. play fine!
(the verification length excludes any tags that may be at the start of the file)
