Failed to read audiofile

Hi,

I'm trying Beatunes.

The Library is folder based.

There's around 6000 tracks, only 4000 are showing up in beatunes.

This is what I found a lot in the logs :
2020-07-25 13:34:00,239 [205335] [ERROR][HibernateFileSystemLibraryLoader] com.tagtraum.audiokern.AudioMetaData: Failed to create AudioMetaData object: com.tagtraum.audiokern.AudioMetaDataException: Failed to read audiofile /xxx.m4a

I looked at the files permissions and stuff, I tried but couldn't find how to fix it.

When I switch the library to itunes based, the 6000 files are showing up.
The same files with the error message can be played and analyzed.

Any idea ?

Thanks

   Hey there,

   thanks for the logs.

   When using beaTunes for a folder-based library, all metadata (like id3 tags) is read using the library jaudiotagger. Apparently it believes your .m4a files are malformed and therefore cannot read them.

   When using beaTunes together with iTunes or Music.app, metadata is (in many cases) not read by beaTunes itself, but by iTunes/Music.app, which does not seem to have a problem with your files.

   Since jaudiotagger usually does not have an issue with .m4a files, there is at least something unusual about yours. To get to the bottom of this, I'd have to actually have one of these files for testing. Can you send one please?

   That all said, files don't get into this state on there own. Is there anything you did with them that could explain this? I.e. used some tagging software or so?

   Thank you,

   -hendrik

   Hey,

   thanks for the file. It indeed appears to be malformed. I have checked with AtomicParsely. It reports

   APar_readX_noseek read failed, expect 8, got 1: end of file
   

   which basically means that the file ended prematurely. This kind of error may be ignored by some software packages and leads to errors with others.

   Thanks for the quick answer.

   Do you know any way to fix this?

   Thanks again.

   Hi,

   I have implemented a workaround for this for Jaudiotagger (here). But it will take a while (at least a week or two, but that is no promise!) until it finds its way into beaTunes.

   If you're Python-savy, you might want to run mp4file --optimize (see mp4file) on your .m4a files. The file you sent to me was fixed by this (the extra byte at the end was removed).

   Hope this helps,

   I converted them in flac and they were instantly added to the Beatunes library.

   Thanks

    That's another way of solving the issue! :-)
