Trying to recover an MP4 file that is 157MB in size. This is the tail end of the output after running the program. I used an MP4 that worked First byte expected 0. Track 0 codec: mp4a mp4a: Success because of large s value. [aac @ 0x5590b8020cc0] channel element 2.8 is not allocated Duration: 0

Invalid length: -1052488119. Wrong match in track: 0. Track 1 codec: avc1 avc1: Failed for no particular reason. Found 1 packets.

Saving to: /home/charles/Desktop/mp4temp/snag2.mp4_fixed.mp4 Track 0 (mp4a): duration: 0 timescale: 44100 Adjusting track duration to movie timescale: New duration: 0 timescale: 44100. Track 1 (avc1): duration: 1503 timescale: 15000 Adjusting track duration to movie timescale: New duration: 4419 timescale: 44100. Movie duration: 4419 timescale: 44100

Any suggestions on how to fix this issue?

In case you are using ffmpeg instead of avlib, your issue might got fixed with 'support using ffmpeg > 3.3'.

Otherwise, in order to help you, the files are needed. Just the log is not enough.

I'm having a very similar if not the same issue:

Would you send me the samples, so I can see what's the problem?

I can't because they contain footage of other people, and I need their permission for distributing these videos. I can however have a call with you if you're willing, and we can investigate. How does that sound to you?

if you could share a couples video from the same source it could be enough at least yo ser whay yhe problem could be.. Anyway just write me an email at [email protected] and we can arrange a call, it's fine for me.
