Interesting! Please send me the files (healthy+broken) to the email mentioned on my profile. For uploading you can use wetransfer.

OK, but these are XXX films. You OK with that?

anthwlock commented 4 years ago

yes, as long as it contains nothing illegal

anthwlock commented 4 years ago

For some reason your files contain two mdat atoms, the first one containing nothing but itself. untrunc now skips such mdat atoms. However, it probably would still fail if the first one wasn't empty. But since I have no such file, I can't test this further.

Will close this soon if you don't report any further problems/bugs.

So I should re-pull source from git and try it again?

anthwlock commented 4 years ago

sounds reasonable.
