VLC srpos plugin - Automatic save playback position in VLCSection: Video | Actuality: Unspecified
Srpos automatically saves and restores the last played position unlike some other extensions, such as Remember Position that require you to click on to restore and maintain this position.
Installation into Linux Mint:
sudo add-apt-repository ppa:samrog131/ppa sudo apt update sudo apt install vlc-srpos-plugin
For older releases, you may need to update your version of VLC.
If you do not want to add the PPA to your system, you can download the plugin Srpos for VLC as a deb package from here.
Once you have enabled this option, restart VLC.
