First time user of untrunc so please excuse my ignorance. I have a file that is not playing with a size of 1.49GB and have multiple files that are working from the same camera but so far none of the ones I have tried was able to help me create a playable file.
I am using untrunc on MacOS from an image container via the supplied Dockerfile but can build it locally from scratch if you think it will change anything, since this one uses ffmpeg 3.4.11-0ubuntu0.1.
The error I am getting is the one of the title: Error: unable to find correct codec -> premature end (~0.00165%)
Does it matter the size of the "OK" files? Do they need to be larger than the "to be repaired" file?
I have tried with files around 400MB, 500MB and 1.2GB.
Would it make any difference if I keep trying with other "OK" files?
Any other ideas or pointers please?
Thanks and regards
