Main thread hangs in java.io.FileInputStream.readBytes

[SalomonBrys]

Panako can succesfully store all my MP3 collection, except a few MP3 files (that are perfectly playable) that makes it hang forever.
Here one of the MP3 files in question : https://mega.nz/file/pKFVDAyb#vtjUcy2UfDPt5SJMl7HFTRsnZxFC3vRG_Cqyo0w8fGE

[0] % panako store "Blondie - Maria.mp3"
Audiofile;Audio duration;Fingerprinting duration;ratio

I've extracted the main thread stacktrace with Mission Control:

The same freeze (in java.io.FileInputStream.readBytes) is happening with panako print "Blondie - Maria.mp3".

So, it looks like it's an FFMPEG handling problem.
Looks like the ffmpeg process never completes.

I can see it:

[130] % ps aux | grep ffmpeg
salomonbrys      57759   0.0  0.0 34681224  11468 s000  S+   12:45PM   0:00.19 ffmpeg -ss 0.0 -i /Users/salomonbrys/Downloads/Blondie - Maria.mp3 -vn -ar 16000 -ac 1 -sample_fmt s16 -f s16le pipe:1

If I kill the process (in this instance kill -9 57759), then panako completes succefully.

However, when I run this command manually, it completes correctly, so it looks like it's an issue of the process management by Panako / the JVM.

This issue is fixed by JorenSix/TarsosDSP#212

Thanks for the bug report. I have updated the TarsosDSP dependency, using the maven package which should fix this problem.
Thanks again for digging and reporting this issue!
