untrunc on Ubuntu 16.04.2 LTS

[jauling]

Are there maybe some options I can pass to untrunc to get this to work right? Correct me if I'm wrong, but it looks like this output suggests that untrunc has some problems reading the 'ok' file?

i have exactly the same error, and it would seem you have the same camera as my, may i ask which one? i recently brought 2 elecam elite and so far most of the videos i have shot with them have been corrupted .. i did think it was my memory cards as they are unbranded and had problems saving at all till i formatted with minitool partition and been searching for a way to recover my videos.

Hi @wolfied sorry for the delayed response. I have a Gitup Git2 camera. I think maybe there is an onboard battery short, which I've heard happens sometimes. I've had the camera for a couple years now, and its only malfunctioned this one time.

I think my Samsung EVO microSD card is fine.

[wolfied]

I descovered the underlying prob for me was the cards themselves they were faked 32gb . And would only save the first file partial second then the rest just blank.. I brought 2 samsung evo+ and recorded a straight 3hrs on both cameras no problem. :)

Hi, @jauling did you had any more luck later? I got the same error and am still not sure were the problem started.

I think the problem are the data streams. (and lack of error reporting, sorry!).

To rebuild the index untrunc needs to determine start and length of all packets, and has no idea of what to do with the data.

It might be possible to discard those streams, with some modification, (and some luck). Could you send me a couple of samples (one at least working)?

Can do. I will send them later this day. Luckily I have at least 3 of both, working and broken. Vg Chris
