user14458: I have an app which records mp4. Some videos are fine and some corrupt. But even the corrupt ones are huge in size which I conclude have data.However, I have tried ffmpg, avconv and media info. I am pasting media info from both working and corr ones. How do I recover the corrupt video ?
Possible solution:
I found this webpage (look at the Incomplete files - or not finalised  section). I am guessing this is one of the issues that while recording my phone would have died ? Anyway to recover this ? If you notice in the ffmpeg output only for corrupt video that the video stream is not detected.I do not know how to do this on ubuntu.

user16042: Untrunc may be able to help.  
It's a Linux based command line utility that will restore lost MOOV sections.  Using it currently requires libav and a C++ build environment, though instructions are provided to do the build.  After it is built, you call it via the command line and just provide the path to a working video from the same phone, the broken video and it will write out a new file that should hopefully work.

<p>It's a Linux based command line utility that will restore lost MOOV sections.  Using it currently requires libav and a C++ build environment, though instructions are provided to do the build.  After it is built, you call it via the command line and just provide the path to a working video from the same phone, the broken video and it will write out a new file that should hopefully work.</p>
