"Trying to add item, but missing meta box" error #2832
Comments
I looks like trackID 3 is no longer present after import (I added a more explicit check in mp4box for that). Can you run a -info on the output file without the -set-meta and -add-item options ? |

Hello,
I need to extract some additional data (GoPro GPS data) from a MP4 file and add them to another MP4 file.
I'm able to extract them with the command
mp4box.exe -raw 3 ..\video.mp4
But when I try to import them again with this command
mp4box.exe -add ..\GoproVideo.mp4 -set-meta meta:tk=3 -add-item ..\video_track3.gpmd:tk=3 -new output.mp4
I got the following error
Trying to add item, but missing meta box
Am I missing something? Looking at the documentation, command line seems ok because I set the meta type and then add the item to it. Should I create first the track3? Or is automatically created with the set-meta command?
This is what I get if I run a -info on the original file
