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
