`Info: version 'v364-bd783dd' using ffmpeg '3.3.4' Lavc57.89.100 Info: reading DJI_0154.mp4 Info: parsing healthy moov atom ... Composition time offset atom found. Out of order samples possible.

Damaged file is > 2GB and seems the tool sees 7 mins of footage but still the chunk error.

Please send me the files (healthy+broken) and I might take a look at some point. You can upload them on dropmefiles.net. If you think they are too big, you can use untrunc -sh file.mp4. In case you want to keep the link private, you can send me an email - see my Profile page. Thank you!
