I am trying to combine chunks of reversed videos but this error hits me. I have seen many solutions but none of them worked.

[mov,mp4,m4a,3gp,3g2,mj2 @ 0xe8db4600] moov atom not found
/storage/emulated/0/Movies/VideoPartsReverse/reverse_video0.mp4: Invalid data found when processing input

This is the command for concatenation.

[-i, /storage/emulated/0/Movies/VideoPartsReverse/reverse_video1.mp4, -i, /storage/emulated/0/Movies/VideoPartsReverse/reverse_video0.mp4, -filter_complex, [0:v0] [0:a0] [1:v1] [1:a1] concat=n=2:v=1:a=1 [v] [a], -movflags, faststart, -preset, ultrafast, -map, [v], -map, [a], /storage/emulated/0/Movies/reverse_video.mp4]

Even adding this didn't help -movflags, faststart

this is the detailed error message

mov,mp4,m4a,3gp,3g2,mj2 @ 0xe8db4600 moov atom not found Invalid data found when processing input

moov atom not found can be a pain. because you have to stream the content and recreate an mp4 in order to get this metadata created. For Windows, follow the instructions from here: https://www.videohelp.com/software/recover-mp4-to-h264

Step 1: Use any good previous file with the same resolution and bitrate to generate the header files

Step 2: Recover streams from the corrupted file

Step 3: Use any other utility (Yamb or ffmpeg for example) to recreate the MP4/MOV file from the streams (recovered.h264 and recovered.aac).

  • I have tried the solution above, not worked for me. However, I found another better solution in that website https://www.videohelp.com/software/MP4-Repair-untrunc-GUI. This software integrates the famous untrunc and ffmpeg into a GUI version, thus can repair the videos in a very simple manner. – 童学智 Jan 15 '22 at 22:51
