Hi,
I have a problem with some gopro mp4 files, I tried to play those with several player but they doesn't works, if I try to fix with ffmpeg with the command

Code:
ffmpeg -i GX010018.MP4 -vcodec copy -acodec copy -movflags faststart out.mp4


i get this error

Code:
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x557822cb4180] moov atom not found
GX010018.MP4: Invalid data found when processing input


It's strange because gopro split the records in files of 4GB if bigger and only those files give me problems, the others (with less of 4GB size) are ok

I download files from gopro with gphoto2, same issue on two different computers

can somebody help me to fix those mp4 files? thanks a lot in advance

I cannot merge the files in any way, all the ways tried tell me the file type is not supported or corrupt

Hm. I wonder if the files are splitted without any termination..?

You could try
Code:
cat video_01.mp4 video_02.mp4 video_03.mp4 > full_video.mp4
... and then try to play it.
