Similar thing happens to me as well. The bad video is 1.4 GB, and the good video is 1.5 mb, both from the same source (twitch.tv recordings). The errors shown below seem to continue for at least 5 minutes unless I stop them.

Hi! Same problem here. Source files are GoPro Hero5, 4K video format. Any idea what is causing this?

same problem here

charsi commented 5 years ago

Was having the same problem. Adding the -a flag fixed it somehow and I got a working file!

I don't even know what -a is supposed to do. It is undocumented.

anthwlock commented 5 years ago

untrunc -a <ok.mp4> lets you analyze (Mp4::analyze) the codecs inside ok.mp4 It should not change the result of Mp4::repair.

Future readers should try this fork, it even supports GoPro videos!

gregology commented 4 years ago

How do you add flags to the untrunc command when using the docker container?
