Yeah sorry for providing poor information about my issue and thanks for helping. 
I am in need of streaming a TS 1080i file from my Vu+ satellite, linux based decoder for a MagicMirror project.
It was running fine and smooth on a poor Raspberry Pi 3 B+ by using either omxplayer or VLC, but it is not on the powerfull Rock Pi 4B.
Do you still think that moving to Ubuntu Server would do the trick? 
Here are the example informations of a 1080i stream (taken from the Windows 10 version):
Also @NicoD if you live in Europe and are in need of the Rock Pi 4 you can already buy it at https://www.innet24.de/ or at http://www.pishop.at/ .
