Description

Hey,

I'm using ffmpeg version

ffmpeg version 4.2.1 Copyright (c) 2000-2019 the FFmpeg developers
  built with Apple clang version 11.0.0 (clang-1100.0.33.8)

When I try to process this video https://s3-ap-southeast-1.amazonaws.com/filestore.getselect.co/IMG_0029.mp4 using this command

ffmpeg -i IMG_0029.mp4 -y newvideo2.mp4

I get this output

[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f8a1f008200] could not find corresponding trex (id 1)
[mov,mp4,m4a,3gp,3g2,mj2 @ 0x7f8a1f008200] could not find corresponding track id 0

IMG_0029.mp4: Invalid data found when processing input

I don't understand what is the problem as the video is playable.

Would appreciate any help.

How was the input file created?

by using a tool online (redv.co) to download reddit video

comment:4 by Balling, 14 months ago

redv.co -- very bad idea. Try to use youtube-dl, it supports reddit.

Ok but this is not the point. This video is a potential video our users can have on their device so I want to be able to compress also videos that were created by redv.co.

Sorry, but I don't understand this report: You found a website that can produce invalid mov files, ffmpeg allows to read such files, what would you like to change?

Why are we even discussing the website? ... I have an mp4 file that is playable in all devices and computers so clearly the file is not corrupted, however, when I try to compress it using ffmpeg I get the above error.

Maybe it is a bug that got fixed in the latest ffmpeg version?

After installing version 4.3.1 I no longer have the error message, however, the command ffmpeg -i IMG_0029.mp4 -y newvideo2.mp4 only produces a 5 seconds videos instead of the full length which is 2 minutes and 20 seconds.

Do you know why?
