I have multiple video series in different folders.
Need a video player with tracking feature - remember which video last played.
Almost got it : the great VLC has it. https://www.vlchelp.com/grouping-listing-video-orientation-android/
Still, I am looking for other apps…
There is Just (Video) Player ;) https://f-droid.org/packages/com.brouken.player/
Thanks for this. But the fdroid release seems outdated compared to GitHub.
