merging Multi-Track MP4 Files with ffmpeg show error time porgress bar
9 juillet 2024, par EasonWaiiI need to merge two videos into one using ffmpeg. The resulting video should have two video tracks and one audio track, with the audio track taken from the longer video.


When playing the merged video in a player like PotPlayer or VLC, it should default to playing the shorter video track. However, users should be able to switch to the other video track if they want.


The problem I am facing :
Everything is working fine, except when the player defaults to the shorter video track, it shows the timeline of the longer video track.

I want the timeline to display correctly according to the shorter video track when it is being played, without truncating the timeline of the longer video track and affecting its playback.
