Missing Movie Header Atom #17

Closed d1ma5 closed 5 years ago

d1ma5 commented 5 years ago

Hello,

I have a truncated mp4 file that i produced using a home brewed powershell script that leverages ffmpeg to record a multicast stream. Script was not able to lay down the last atom moov packet and I now have a 7.3GB file that is not playable. I tried using the windows (x64) exe to read another working mp4 file that was created the same exact way but i keep getting "Missing movie header atom"

What am i doing wrong?

Are you sure the first argument is the healthy one? If so what is the output of untrunc -i ok.mp4 and untrunc -f ok.mp4? Please also provide the output of mp4dump.

I recorded a live even with this:

fmpeg -i 'rtsp://192.168.1.2/?inst=1&enableaudio=1&audio_line=1' -map 0 -c:v libx264 -c:a aac stream.mp4

Computer froze a while after the event. Trying to play it I get "missing moov atom" and trying to repair it with untrunc I get "missing movie header atom".

Mp4dump gives:

Recording from the same camera, and closing normally, gives:

All the obvious non-movie-buff approaches so far have failed ie .playing with different players, trying to force settings with ffplay and ffmpeg. Any ideas? Will post here if I figure it out.

The easiest solution to fix this was running this on wine: https://codecpack.co/download/recover-mp4.html
