AAX Audio Converter flags error message on some .aa file types about aaxaudioconverter

[Sailfish]

Okay, seeing how fast the aax transcoding work versus .aa, I have already decided to go ahead and download the aax version for all author titles I have flagged as worth listening to again. With well over 1000 titles, and most of them flagged as worthy, that will be a daunting task but one, ultimately, be worth it.

Thanks for your time on this.

I've attached the log file as requested

Where can I find it?

[Sailfish]

That's odd? I know I used the "Attach files by dragging & dropping, selecting or pasting them." feature below. ah, I see now that the attachment didn't work with an older version of Firefox that I was using. I will be using it again but since the log is short I will also add it here. Let me know if you receive the attachment.

Thank you. It appears to be related with the initial reading of the meta data. I will investigate.

[Sailfish]

As an aside, using the "-Log=3" command line switch on all the *.aa titles in my library, I was able to ID and isolate the 14 files that have exhibited this problem. I can run AAC with just those files and send that log file if you think it would be of help.

Also, if you find something and wish me to test it out, I will be able to efficiently do so with just-Log=3 those files.

[audiamus]

AAX Audio Converter uses a 3rd party library to extract the meta data, not FFmpeg directly. Nonetheless it might help to see what FFmpeg does with it. Can you try two things please:

1. Run the following command from a console window:
   <path to>\ffmpeg.exe -hide_banner -i <offending file>.aa 2> out.txt
   FFmpeg.exe will be in the same folder as AAXAudioConverter.exe.
   One of the problematic files appears to be DeadSixPart3_mp332_ARKLXNBG8DW1U.aa

2. Run the original AAX Audio Converter session again, but this time with log level 4 and let's see how and if FFmpeg will be involved.

Per your request, attached are the item 1 ffmpeg output file and your AAC log file.

Note: apologies for mixing two issues in my response earlier. I've deleted that response and broke them into responses to the appropriate issues separately.

[audiamus]

Thank you again. That's all I need at the moment. At first glance, there is nothing unusual in the FFmpeg output. I will have to dig into the source code.

[audiamus]

It could be the cover image. Audible has used more than one way of embedding the cover image into the .aa file. AAX Audio Converter is aware to two methods, but neither might fit here.

I will handle this exception differently in the next version, to allow such books to be loaded even without the cover image.

For the moment I recommend to download the .aax variant.
