HOW TO APPLY TRANSITION EFFECTS IN FFMPEG ? [closed]
8 janvier 2023, par SMARTI have 7 videos with audio, i tried to apply transition effects on these files, written code in python for this , i got error .


python code :

Issue with repairing 3GP video using untrunc - Error : bad track : 's263'
2 juillet 2023, par sifiribI am trying to repair a corrupted 3GP video using the untrunc program, but I'm facing an issue due to an error.


The command I ran :


./untrunc -v ~/Desktop/logic/Video0086.3gp ~/Desktop/logic/Video0035.3gp



I am running Ubuntu 20.04 LTS and using the 'v308-d72ec32' version of the untrunc. The error message I encounter is as follows :

**Error: bad track: 's263'**



This error message indicates that the untrunc program is having trouble with a track named 's263'. This track could be a track or codec within the video file.


How can I resolve this error and successfully repair the corrupted 3GP video ? What steps should I follow or can you suggest an alternative approach ?


Thank you in advance !


I was expecting trunc tool to fix the corrupted/trunced video. But it gave me this error and no matter how much I searched for a solution, I couldn't find anything.
