Problem with --stop-time in vlc-3.0.2

Hi all

I have a problem with vlc-3.0.2 when i want to convert a video file from one format to mp4 format. The problem has occured when i use the "--stop-time" option of vlc command line to convert only some part of video file ( not all of it ).

The problem is that the "--stop-time" option has no effect and all of video file is converted.

I had not this problem with vlc-2.-- and i have this problem only with vlc verion 3.0.2 .

I am using the Ubuntu 18.04 and vlc for linux from the ubuntu original repository .

Extra explanation : I even tested the "--run-time" option for solving above problem , but "--run-time" also had no effect :-(

I have a bash shell script that i used it for converting , and i was using it with vlc-2.-- and anything was ok but when i use that script with vlc-3.0.2 the --stop-time had no effect :-(

I am using the vlc-3.0.2 on ubuntu 18.04 and the vlc-2.* on ubuntu 17.10 . And my hardware is an Intel-Core-i7 based PC . And both versions of vlc was not compiled by myself , both are installed from formal ubuntu software repository.

This problem is occured every time with vlc-3.0.2 not often .
