I was meaning that it works for a very small test, not that it was working on a large scope of inputs...

After more tests I hit some problems with some videos:
ffmpeg -hide_banner  -i /mnt/archivescollection/test_file.iso -f null -af ebur128=peak=true:framelog=verbose -vf idet,cropdetect=0.12:2:1 -y /dev/null /mnt/archivescollection/test_file.iso: Invalid data found when processing input

Those .iso works when mounted manually.

OK, understood.

Thanks for your time.
